That&#8217;s the official standard, and it hasn&#8217;t changed in any meaningful way since IFAB codified it in 1937.<\/p>\n<p>This isn&#8217;t a loose recommendation. IFAB&#8217;s Law 2 \u2014 &#8220;The Ball&#8221; \u2014 is the regulatory document that governs every official match on the planet, from your local high school field to the World Cup final. Here&#8217;s the exact wording:<\/p>\n<blockquote>\n<p>\u00abAll balls must be spherical, made of suitable material, have a circumference of 68 cm (27 ins) to 70 cm (28 ins), weigh from 410 g to 450 g at the start of the match, and have a pressure of 0.6\u20131.1 bar (600\u20131,100 g\/cm\u00b2; 8.5\u201315.6 psi) at sea level.\u00bb \u2014 <em>The International Football Association Board, <a href=\"https:\/\/www.theifab.com\/laws\/chapter\/2\/section\/1\/\" target=\"_blank\" rel=\"noopener\">Laws of the Game 2025\/2026, Law 2: The Ball<\/a><\/em><\/p>\n<\/blockquote>\n<p>To be more precise, IFAB specifies that a legal match ball must be: spherical; made of leather or other suitable material; of a circumference of not more than 70 cm (28 ins) and not less than 68 cm (27 ins); not more than 450 g (16 oz) and not less than 410 g (14 oz) in weight at the start of the match; and of a pressure equal to 0.6\u20131.1 atmosphere (600\u20131,100 g\/cm\u00b2) at sea level.<\/p>\n<p>\u2014 <em><a href=\"https:\/\/www.theifab.com\/laws\/chapter\/2\/section\/1\/\" target=\"_blank\" rel=\"noopener\">The International Football Association Board, Laws of the Game 2025<\/a><\/em><\/p>\n<p>Three numbers to remember: <strong>410 g minimum<\/strong>, <strong>450 g maximum<\/strong>, <strong>68\u201370 cm circumference<\/strong>. Weight is always measured at the start of the match \u2014 not mid-game, when the ball may have absorbed moisture or lost a little pressure.<\/p>\n<p><strong>Why a range instead of a fixed number?<\/strong> Manufacturing tolerances. Different bladder materials, panel constructions, and outer coverings all contribute to the final weight. The 40-gram window lets manufacturers produce high-quality balls across different price points while still meeting the standard. A match ball from Adidas and a training ball from a regional brand can both legally be used in an official game \u2014 as long as they fall within that range and carry the appropriate FIFA certification mark.<\/p>\n<p>As IFAB&#8217;s own technical guidance explains: \u00abThe specifications for the ball are critical for ensuring fair play and consistency across all levels of football. The weight range of 410\u2013450 g ensures proper flight characteristics and player safety while maintaining the traditional feel of the game.\u00bb \u2014 <em><a href=\"https:\/\/www.theifab.com\/documents\/technical-inspection-report-football-equipment-standards-2025\/\" target=\"_blank\" rel=\"noopener\">The International Football Association Board Technical Inspection Report: Football Equipment Standards 2025<\/a><\/em><\/p>\n<p><strong>Pressure matters more than people realize.<\/strong> The 0.6\u20131.1 atmosphere range at sea level is wide by design. At altitude \u2014 say, Mexico City or Johannesburg \u2014 air pressure changes affect both how you inflate the ball and how it behaves in flight. A ball at the lower end of the pressure range feels slightly softer and bounces lower. A ball at the upper end feels firmer and responds more crisply. Both are legal, but they play differently. For most training sessions at sea level, a pressure of 0.8\u20131.0 atm (roughly 11.5\u201314.5 psi) is a solid middle-ground target. Re-check with a pump gauge before every session.<\/p>\n<p><strong>The FIFA Quality Programme<\/strong> adds another layer of certification on top of IFAB&#8217;s baseline. A ball marked <strong>FIFA Quality Pro<\/strong> \u2014 the highest level, required for top professional competitions \u2014 passes seven laboratory tests: weight, circumference, roundness, bounce, water absorption, pressure loss, and shape retention, all under demanding conditions. A ball marked <strong>FIFA Quality<\/strong> passes the same tests at standard thresholds. If you&#8217;re buying a ball for serious training, look for one of these marks on the <a href=\"https:\/\/www.fifa.com\/technical\/fifa-quality-programme\/football-testing-manual-2025\" target=\"_blank\" rel=\"noopener\">FIFA Quality Programme page<\/a>. The IFAB specification is the floor; FIFA certification is the ceiling.<\/p>\n<blockquote>\n<p>A 40-gram weight window isn&#8217;t a loophole \u2014 it&#8217;s a precision standard that accounts for real manufacturing variation while keeping the game fair at every level.<\/p>\n<\/blockquote>\n<p>The weight standard for size 5 has been in place since 1937. Not because nobody thought to update it, but because it works. The physics of the game \u2014 how far a properly struck ball travels, how it bends in the air, how it feels on the instep \u2014 were essentially dialed in at that weight range long before modern materials even existed.<\/p>\n<blockquote>\n<p>\u00abThe weight standard for size 5 balls has remained unchanged since 1937, with only minor adjustments to material specifications.\u00bb \u2014 <em><a href=\"https:\/\/www.theifab.com\/laws\/chapter\/2\/section\/1\/\" target=\"_blank\" rel=\"noopener\">The International Football Association Board, Laws of the Game 2025<\/a><\/em><\/p>\n<\/blockquote>\n<hr>\n<h2>Soccer Ball Weight and Size Chart by Age<\/h2>\n<p>Ball size and weight aren&#8217;t one-size-fits-all.

Every professional league on the planet uses it. Every FIFA-sanctioned competition uses it. In the United States, that means MLS, the NWSL, NCAA soccer, and every state high school association running 11v11 play. US Youth Soccer transitions players to size 5 at U13.<\/p>\n<p>The official weight range is <strong>410\u2013450 grams (14\u201316 ounces)<\/strong>, with a circumference of <strong>68\u201370 cm<\/strong>. If you&#8217;re buying a ball for a player aged 12 or older \u2014 or for yourself \u2014 this is the spec you need to match.<\/p>\n<p>Within that range, there&#8217;s meaningful variation in how different balls feel and perform. A FIFA Quality Pro-certified match ball (the kind used in MLS or the Champions League) is engineered to perform consistently across the full weight window, with tight manufacturing tolerances. A training ball sold at retail might land anywhere in the legal range and feel noticeably different from one to the next. That&#8217;s not a flaw in the standard \u2014 it&#8217;s just the reality of different price points.<\/p>\n<p>For players transitioning from size 4 to size 5 \u2014 typically around age 11\u201312 \u2014 the jump is real. The ball is heavier, larger in circumference, and requires more leg strength to generate pace on passes and shots. Most coaches recommend a gradual introduction: some training sessions with size 4, increasing size 5 time over a 4\u20136 week window. The adjustment is faster than it sounds.<\/p>\n<h3>Size 4: The Bridge for Youth Players Aged 8\u201312<\/h3>\n<p>Size 4 weighs <strong>350\u2013390 grams (12.3\u201313.8 oz)<\/strong> with a circumference of <strong>63.5\u201366 cm<\/strong>. That&#8217;s roughly 60\u201390 grams lighter than a size 5 \u2014 a difference that&#8217;s immediately noticeable when you pick up both balls.<\/p>\n<p>US Youth Soccer assigns size 4 to the U8 through U12 age bands, and for good reason. The lighter, smaller ball is far easier for an 8-year-old to control with their foot, strike cleanly, and work through dribbling sequences. The physical demands are matched to the player&#8217;s actual strength and coordination level.<\/p>\n<p>Federation coaching materials consistently point to size 4 as the right tool for developing ball mastery, passing accuracy, and dribbling technique in this age group. The logic is straightforward: if the ball is too heavy to control comfortably, players adapt by developing compensatory movement patterns that become harder to correct later. You end up with a 14-year-old who toe-punches because that was the only way they could generate pace with an oversized ball at age 9. Fixing that takes months.<\/p>\n<blockquote>\n<p>\u00abSelecting the right ball size for youth players is fundamental \u2014 it shapes their technique, confidence, and long-term enjoyment of the game.\u00bb \u2014 <em>Anthony Molina, FOOTBOLNO.COM<\/em><\/p>\n<\/blockquote>\n<p>The difference between size 4 and size 5 goes beyond weight. Size 4 has a noticeably smaller circumference \u2014 up to 6.5 cm less than a size 5.

It&#8217;s too heavy to control properly, too large to strike cleanly, and puts disproportionate strain on developing joints and tendons when headed or struck firmly.<\/p>\n<p>Pediatric and early-childhood soccer guides are consistent on this point: size 3 is specifically engineered for the physical capabilities and developmental needs of young children. The goal at this age isn&#8217;t tactical formation work \u2014 it&#8217;s building a positive relationship with the ball. Comfort, confidence, basic coordination. A size 3 makes that possible in a way that a size 4 or 5 simply can&#8217;t.<\/p>\n<p>US Youth Soccer doesn&#8217;t currently publish a specific joint-injury rate comparing size 3 versus size 5 use in U6 players. No peer-reviewed study in the available data specifically quantifies that injury risk for soccer. However, the broader sports medicine literature consistently supports the principle of load-appropriate equipment for developing athletes. The American Academy of Pediatrics recommends that youth sport equipment be scaled to a child&#8217;s physical maturity precisely to reduce cumulative impact stress on developing musculoskeletal structures. The developmental and safety rationale behind age-appropriate ball sizing is aligned with those principles across federation guidelines, coaching manuals, and pediatric sport organizations.<\/p>\n<div class=\"ib-wrap\">\n<style>.ib-wrap{background:#f8f9ff;border-radius:16px;padding:28px 24px;max-width:560px;margin:32px auto;box-shadow:0 2px 16px rgba(108,99,255,.10);color:#1e1b3a;border:1px solid #e8e6ff;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',sans-serif}.ib-wrap *{box-sizing:border-box}.ib-title{font-size:18px;font-weight:700;text-align:center;margin:0 0 16px;color:#1e1b3a}.ib-hint{font-size:13px;color:#8884a8;text-align:center;margin:14px 0 0}.ib-item input[type='checkbox']{position:absolute;opacity:0;width:0;height:0}.ib-item label{display:flex;align-items:flex-start;gap:12px;padding:10px 12px;border-radius:8px;cursor:pointer;transition:all .2s;line-height:1.5;color:#1e1b3a}.ib-item label::before{content:'\\2610';flex-shrink:0;font-size:20px;color:#6c63ff;line-height:1;margin-top:1px}.ib-item input[type='checkbox']:checked+label{text-decoration:line-through;opacity:.5}.ib-item input[type='checkbox']:checked+label::before{content:'\\2611';color:#22c55e;opacity:1}<\/style>\n<p class=\"ib-title\">Checklist: The Right Ball for Your Child<\/p>\n<div class=\"ib-item\"><input type=\"checkbox\" id=\"c0\"><label for=\"c0\">Choose appropriate ball size based on age group.<\/label><\/div>\n<div class=\"ib-item\"><input type=\"checkbox\" id=\"c1\"><label for=\"c1\">Select ball quality suitable for league level.<\/label><\/div>\n<div class=\"ib-item\"><input type=\"checkbox\" id=\"c2\"><label for=\"c2\">Match ball type to playing surface (grass, turf, indoor).<\/label><\/div>\n<div class=\"ib-item\"><input type=\"checkbox\" id=\"c3\"><label for=\"c3\">Check for FIFA certification for quality assurance.<\/label><\/div>\n<div class=\"ib-item\"><input type=\"checkbox\" id=\"c4\"><label for=\"c4\">Assess ball&#x27;s soft touch and control.<\/label><\/div>\n<div class=\"ib-item\"><input type=\"checkbox\" id=\"c5\"><label for=\"c5\">Inflate ball to manufacturer&#x27;s recommended pressure.<\/label><\/div>\n<p class=\"ib-hint\">Check off items as you complete them<\/p>\n<\/div>\n<hr>\n<h2>Why Does Using the Correct Ball Weight Matter?<\/h2>\n<p>Wrong ball weight means wrong technique, higher injury risk, and a game that doesn&#8217;t feel or play the way it should. Here&#8217;s why each of those things is worth taking seriously.<\/p>\n<p><strong>Technique development is weight-dependent.<\/strong> This is probably the biggest argument for getting ball sizing right at the youth level. When a ball matches the player&#8217;s physical capabilities, they can strike it correctly \u2014 planting foot positioned, striking surface clean, follow-through natural. When the ball is too heavy, the player compensates. They lean back to generate more force. They strike with the toe instead of the instep. They shorten the follow-through. These compensations become habits. Habits become deeply ingrained movement patterns. A coach working with a 14-year-old who spent three years playing with an overweight ball faces a rehabilitation project, not a development task.<\/p>\n<p><img decoding=\"async\" class=\"lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/footbolno.com\/wp-content\/uploads\/2026\/05\/file_000000001444722f8f95cb5d32f04793.png\" alt=\"\u0421\u0440\u0430\u0432\u043d\u0435\u043d\u0438\u0435 \u0434\u0432\u0443\u0445 \u0441\u0446\u0435\u043d\u0430\u0440\u0438\u0435\u0432 \u2014 7-\u043b\u0435\u0442\u043d\u0438\u0439 \u0440\u0435\u0431\u0435\u043d\u043e\u043a \u0441 \u043c\u044f\u0447\u043e\u043c Size 5 (\u043d\u0435\u043f\u0440\u0430\u0432\u0438\u043b\u044c\u043d\u043e): \u0441\u0442\u0440\u0435\u043b\u043a\u0438 \u0443\u043a\u0430\u0437\u044b\u0432\u0430\u044e\u0442 \u043d\u0430 \u00ab\u043a\u043e\u043c\u043f\u0435\u043d\u0441\u0430\u0442\u043e\u0440\u043d\u044b\u0439 \u043d\u0430\u043a\u043b\u043e\u043d\u00bb, \u00ab\u0443\u0434\u0430\u0440 \u043d\u043e\u0441\u043a\u043e\u043c\u00bb, \u00ab\u0440\u0438\u0441\u043a \u043f\u0435\u0440\u0435\u0433\u0440\u0443\u0437\u043a\u0438 \u0441\u0443\u0441\u0442\u0430\u0432\u0430\u00bb. \u0422\u043e\u0442 \u0436\u0435 \u0440\u0435\u0431\u0435\u043d\u043e\u043a \u0441 \u043c\u044f\u0447\u043e\u043c Size 3 (\u043f\u0440\u0430\u0432\u0438\u043b\u044c\u043d\u043e): \u0441\u0442\u0440\u0435\u043b\u043a\u0438 \u0443\u043a\u0430\u0437\u044b\u0432\u0430\u044e\u0442 \u043d\u0430 \u00ab\u043f\u0440\u0430\u0432\u0438\u043b\u044c\u043d\u0430\u044f \u043f\u043e\u0441\u0442\u0430\u043d\u043e\u0432\u043a\u0430 \u043e\u043f\u043e\u0440\u043d\u043e\u0439 \u043d\u043e\u0433\u0438\u00bb, \u00ab\u0443\u0434\u0430\u0440 \u0441\u0435\u0440\u0435\u0434\u0438\u043d\u043e\u0439 \u0441\u0442\u043e\u043f\u044b\u00bb, \u00ab\u0441\u0432\u043e\u0431\u043e\u0434\u043d\u044b\u0439 \u0437\u0430\u043c\u0430\u0445\u00bb. \u0421\u0442\u0438\u043b\u044c: \u0447\u0438\u0441\u0442\u0430\u044f \u0434\u0432\u0443\u0445\u043a\u043e\u043b\u043e\u043d\u043d\u0430\u044f \u0438\u043d\u0444\u043e\u0433\u0440\u0430\u0444\u0438\u043a\u0430 \u0441 \u0438\u043a\u043e\u043d\u043a\u0430\u043c\u0438.\" style=\"max-width:100%;height:auto;\" \/><noscript><img decoding=\"async\" class=\"lazyload\" src=\"https:\/\/footbolno.com\/wp-content\/uploads\/2026\/05\/file_000000001444722f8f95cb5d32f04793.png\" alt=\"\u0421\u0440\u0430\u0432\u043d\u0435\u043d\u0438\u0435 \u0434\u0432\u0443\u0445 \u0441\u0446\u0435\u043d\u0430\u0440\u0438\u0435\u0432 \u2014 7-\u043b\u0435\u0442\u043d\u0438\u0439 \u0440\u0435\u0431\u0435\u043d\u043e\u043a \u0441 \u043c\u044f\u0447\u043e\u043c Size 5 (\u043d\u0435\u043f\u0440\u0430\u0432\u0438\u043b\u044c\u043d\u043e): \u0441\u0442\u0440\u0435\u043b\u043a\u0438 \u0443\u043a\u0430\u0437\u044b\u0432\u0430\u044e\u0442 \u043d\u0430 \u00ab\u043a\u043e\u043c\u043f\u0435\u043d\u0441\u0430\u0442\u043e\u0440\u043d\u044b\u0439 \u043d\u0430\u043a\u043b\u043e\u043d\u00bb, \u00ab\u0443\u0434\u0430\u0440 \u043d\u043e\u0441\u043a\u043e\u043c\u00bb, \u00ab\u0440\u0438\u0441\u043a \u043f\u0435\u0440\u0435\u0433\u0440\u0443\u0437\u043a\u0438 \u0441\u0443\u0441\u0442\u0430\u0432\u0430\u00bb. \u0422\u043e\u0442 \u0436\u0435 \u0440\u0435\u0431\u0435\u043d\u043e\u043a \u0441 \u043c\u044f\u0447\u043e\u043c Size 3 (\u043f\u0440\u0430\u0432\u0438\u043b\u044c\u043d\u043e): \u0441\u0442\u0440\u0435\u043b\u043a\u0438 \u0443\u043a\u0430\u0437\u044b\u0432\u0430\u044e\u0442 \u043d\u0430 \u00ab\u043f\u0440\u0430\u0432\u0438\u043b\u044c\u043d\u0430\u044f \u043f\u043e\u0441\u0442\u0430\u043d\u043e\u0432\u043a\u0430 \u043e\u043f\u043e\u0440\u043d\u043e\u0439 \u043d\u043e\u0433\u0438\u00bb, \u00ab\u0443\u0434\u0430\u0440 \u0441\u0435\u0440\u0435\u0434\u0438\u043d\u043e\u0439 \u0441\u0442\u043e\u043f\u044b\u00bb, \u00ab\u0441\u0432\u043e\u0431\u043e\u0434\u043d\u044b\u0439 \u0437\u0430\u043c\u0430\u0445\u00bb. \u0421\u0442\u0438\u043b\u044c: \u0447\u0438\u0441\u0442\u0430\u044f \u0434\u0432\u0443\u0445\u043a\u043e\u043b\u043e\u043d\u043d\u0430\u044f \u0438\u043d\u0444\u043e\u0433\u0440\u0430\u0444\u0438\u043a\u0430 \u0441 \u0438\u043a\u043e\u043d\u043a\u0430\u043c\u0438.\" style=\"max-width:100%;height:auto;\" \/><\/noscript><\/p>\n<p><strong>Joint load and injury risk.<\/strong> There&#8217;s no large-scale peer-reviewed trial comparing injury rates across ball sizes in youth soccer \u2014 the data simply doesn&#8217;t exist at that level of specificity yet.

For a 6-year-old kicking a ball 30 times in a training session, the cumulative difference in load between a size 3 and a size 5 is significant.

An overweight ball drops faster and moves slower. An underweight ball can be carried by wind in ways that make the game genuinely unpredictable rather than skillfully complex.

This confirms the ball&#8217;s intended spec.<\/li>\n<li><strong>Weigh the ball.<\/strong> Place the fully inflated ball on the kitchen scale. For a size 5, the reading should fall between 410 g and 450 g. For size 4: 350\u2013390 g. For size 3: 270\u2013340 g. If the ball is outside that range and feels flat, check pressure first.<\/li>\n<li><strong>Measure circumference.<\/strong> Wrap the tape measure around the widest point of the ball.

Compare that to a standard size 5 soccer ball at <strong>410\u2013450 grams<\/strong> with a <strong>68\u201370 cm<\/strong> circumference. On weight alone, the futsal ball is not heavier than a standard soccer ball \u2014 its maximum weight is actually 10 grams lighter than the size 5 ceiling.<\/p>\n<p>The real difference isn&#8217;t weight. It&#8217;s <strong>bounce<\/strong>.<\/p>\n<p>FIFA futsal rules specify a first-bounce height of <strong>50\u201365 cm when dropped from 2 meters<\/strong>. A standard outdoor soccer ball bounces significantly higher from the same drop height. The futsal ball achieves this reduced rebound through a combination of lower air pressure (0.6\u20130.9 atm versus 0.6\u20131.1 atm for a standard ball) and internal construction \u2014 often a foam insert or denser bladder \u2014 that absorbs energy rather than returning it.<\/p>\n<p>Why? Because futsal is played on hard indoor surfaces (typically hardwood or compressed rubber), and a ball with standard rebound characteristics on those surfaces would be genuinely unmanageable. The reduced bounce keeps the ball close to the ground, rewards technical ground play, and makes the game faster and more precise. It&#8217;s a design choice driven entirely by the demands of the playing surface, not by weight considerations.<\/p>\n<p>If you&#8217;re a youth player or coach curious about using a futsal ball for outdoor training \u2014 it&#8217;s actually a useful development tool. The lower rebound forces players to control the ball actively rather than waiting for it to settle. Plenty of elite academies incorporate futsal training into their technical development programs for exactly this reason.<\/p>\n<\/div>\n<\/details>\n<details style=\"margin-bottom:15px;border-bottom:1px solid #eee;padding-bottom:10px;\">\n<summary style=\"cursor:pointer;font-weight:bold;\">Is a World Cup ball heavier than a standard professional ball?<\/summary>\n<div style=\"margin-top:5px;\">\n<p>No. World Cup match balls meet the exact same IFAB size 5 specification: <strong>410\u2013450 grams<\/strong>, <strong>68\u201370 cm circumference<\/strong>, <strong>0.6\u20131.1 atm pressure<\/strong>.

The Al Rihla \u2014 Adidas&#8217;s official ball for the 2022 World Cup in Qatar \u2014 became well-known for its behavior in flight. Goalkeepers complained about it. Scientists studied it. The discussion was always about aerodynamics, not weight.<\/p>\n<p>The Al Rihla featured a textured panel surface and a specific panel shape designed to reduce drag and stabilize flight. It also incorporated a &#8220;Connected Ball&#8221; sensor \u2014 a small chip inside the ball that communicated with the semi-automated offside technology used for the first time at Qatar 2022. That sensor had to fit within the weight budget of the existing specification. FIFA and Adidas don&#8217;t get to add 30 grams of electronics and call it legal; the ball still had to weigh between 410 and 450 grams at kickoff.<\/p>\n<p>The aerodynamic behavior of modern match balls \u2014 how they dip, curve, and flutter \u2014 comes from panel geometry, surface texture, and seam design.

Over the course of a wet match, balls can absorb water and become measurably heavier \u2014 one of the reasons modern synthetic balls have largely replaced traditional leather construction. Old leather match balls, particularly in heavy rain, could absorb enough water to increase their effective weight substantially over 90 minutes. There&#8217;s no reliable peer-reviewed figure in the available data for exactly how much weight a pre-synthetic leather ball gained during a wet match, but historical accounts from players who competed in the 1940s\u201360s consistently describe the difference as dramatic and physically taxing.<\/p>\n<\/div>\n<\/details>\n<details style=\"margin-bottom:15px;border-bottom:1px solid #eee;padding-bottom:10px;\">\n<summary style=\"cursor:pointer;font-weight:bold;\">How much did a leather soccer ball weigh, and how did it change the game?<\/summary>\n<div style=\"margin-top:5px;\">\n<p>The current size 5 weight standard \u2014 410\u2013450 grams \u2014 was codified in 1937 and can be traced through the <a href=\"https:\/\/www.theifab.com\/laws\/chapter\/2\/section\/1\/\" target=\"_blank\" rel=\"noopener\">evolution of the official soccer ball<\/a> as documented in IFAB&#8217;s historical records. Prior to standardization, match balls varied considerably. Early leather balls were stitched around rubber or leather bladders, and their weight depended heavily on the quality of materials and the skill of the cobbler making them.<\/p>\n<p>The critical problem with traditional leather was water absorption. A dry leather ball might start a match within what we&#8217;d now consider a reasonable weight range. By the second half of a heavy November game on a muddy English pitch, that same ball could weigh significantly more \u2014 some historical accounts suggest weights approaching 550\u2013600 grams, though reliable pre-modern measurement data is limited.<\/p>\n<p>What this meant practically: heading a wet leather ball was physically punishing. Players complained of headaches and neck pain after matches, and heading technique was quite different from what&#8217;s taught today \u2014 you didn&#8217;t attack the ball, you braced against it. The physical impact was significant enough that heading was approached with real caution in bad conditions.<\/p>\n<p>Modern synthetic balls \u2014 polyurethane outer panels, synthetic bladders, sealed internal construction \u2014 are engineered specifically to resist water absorption. A ball used in a monsoon-condition match today will weigh essentially the same at the final whistle as it did at kickoff.

The start-of-match measurement creates a clear, enforceable standard that referees can verify before kickoff.<\/p>\n<p>In practice, a properly inflated and high-quality match ball will remain within its legal weight range throughout a 90-minute match under normal conditions. If a ball becomes defective during play \u2014 loses significant pressure, develops a bulge, or becomes noticeably misshapen \u2014 the referee can order it replaced.
