Every argument about whether football was harder in the past comes back, eventually, to the ball. For most of the game’s history it was a heavy, inconsistent, water-absorbing object that behaved differently in every match, and the skills the game valued were shaped accordingly.
Its development is a good example of a sporting object being improved steadily for a century until it reached a point where players started complaining that it had been improved too much.
Bladders and leather
The earliest footballs were an inflated animal bladder, usually a pig’s, inside a protective casing of stitched leather panels. The bladder gave the shape and the leather stopped it bursting, and the whole thing was closed with a lace where the panels met.
Two problems dominated. The first was consistency: a bladder is not a sphere, and a ball built around one was never quite round, so its flight was unpredictable in ways no player could learn. The second was the lace, a hard raised seam that hurt to head and that made the ball behave differently depending on which part struck the foot.
The move to rubber bladders in the middle of the nineteenth century, following the development of vulcanised rubber, solved the first problem substantially. A rubber bladder inflates into a far more consistent shape, holds pressure, and can be replaced without rebuilding the ball. It is the single most important change in the object’s history.
Why did old footballs get so heavy?
Leather absorbs water. An untreated leather ball in heavy rain gained a significant amount of weight over ninety minutes, and on a muddy pitch it gained more, so a ball that started the match within its specified weight could finish it considerably heavier.
This is the origin of the stories about heading the old ball, and the concern is not misplaced — heading a saturated leather ball with a lace in it was a genuinely punishing act, repeated many times a match by players who did it as a core part of their job.
The fix came in stages. Better tanning, then waterproofing treatments applied to the leather, then synthetic coatings, and eventually fully synthetic outer materials that absorb almost nothing. By the nineteen-seventies the water problem was largely solved; by the nineteen-nineties it was gone.
The black and white ball
The design most people picture — thirty-two panels, twenty white hexagons and twelve black pentagons — was adopted for international football in the late nineteen-sixties and became the standard image of a football worldwide.
The reason was television. Black-and-white broadcasting made a plain brown or white ball difficult to follow, and a high-contrast panel pattern made it visible and made its spin readable on screen. It is a rare case of a sporting object being redesigned for the benefit of people not at the match, and it worked so well that the pattern became the universal symbol for football regardless of what balls actually look like now.
The thirty-two-panel construction had its own merit: it produces a very good approximation of a sphere from flat panels, which is why it remained standard for decades. Squad numbers underwent a similar standardisation for similar visibility reasons, as how squad numbers changed football shirts describes.
What are modern balls made of?
A current match ball has a synthetic outer, usually polyurethane, over several layers of backing fabric and foam, around a latex or butyl bladder. The panels are not stitched but thermally bonded, which removes the seams as channels for water and produces a smoother, more uniform surface.
Panel counts have fallen dramatically. Designs with fourteen, eight or even six panels have been used in major tournaments, with the shapes becoming increasingly unlike anything in the traditional pattern. Fewer panels mean fewer seams and a more consistent surface, which is the whole aim.
That consistency has not been universally welcomed. A very smooth ball behaves differently in flight at high speed, and several tournament balls have been criticised by goalkeepers for unpredictable movement — the aerodynamics of a near-perfect sphere are genuinely less stable than those of a seamed one. Manufacturers have responded by texturing the surface deliberately, which is why modern balls have micro-patterning rather than being smooth.
The specification
The laws set the ball’s properties quite tightly: a spherical ball of specified circumference, within a weight range measured at the start of the match, inflated to a pressure within a defined band. Those numbers have barely changed in over a century, which is why the comparison between old and new balls is about materials rather than dimensions.
What is new is testing. Match balls used in major competitions are certified against standards covering weight, circumference, roundness, rebound, water absorption and pressure retention, which means a modern ball is not just better than an old one — it is guaranteed to be the same as the other balls in the same box. That reliability is what has changed the game most, more than any individual material.
What it means for how the game is played
The ball’s improvement has had consequences that are easy to miss. A consistent, waterproof, perfectly round ball rewards technique over strength, because a precise pass arrives where it was aimed and a struck shot behaves predictably. The long, hopeful clearance that was once a sensible response to an unpredictable object is now simply a worse option than passing.
It has also changed what is coachable. Set-piece routines, in-swinging crosses to a specific zone, and the sort of long diagonal switch that top sides play dozens of times a match all depend on the ball doing the same thing every time. None of that was reliably available to a coach working with a leather ball that gained weight through the afternoon.
The flip side is that certain skills have largely disappeared from the game, including the ability to head a heavy ball repeatedly and the knack of reading a flight that no longer varies. Those were real skills, and the players who had them were not simply doing an easier version of the modern job.
Where it goes next
The current frontier is instrumentation. Balls containing motion sensors have been used in major competitions to provide precise data on the moment of contact, which assists officiating decisions around offside and handball by establishing exactly when a ball was touched.
That is a significant change in what a football is for. For a century and a half it was simply an object to be kicked; it is now also a measuring device, and the data it generates is used to make decisions that affect results. Whether that is an improvement depends on what you think officiating should feel like, but it is the clearest sign yet that the ball’s development has not finished. The culture around the game keeps changing with it, and the story of the football scarf is a good example of how slowly some of it moves.
Frequently asked questions
Were old footballs heavier than modern ones?
Not when dry — the specified weight range has barely changed. The difference is that leather absorbed water, so an old ball became much heavier during a wet match.
Why is a football black and white?
The thirty-two-panel black and white pattern was introduced for visibility on black-and-white television, where a plain ball was hard to follow and its spin impossible to read.
What are modern match balls made from?
A polyurethane outer over backing layers and foam, around a latex or butyl bladder, with panels thermally bonded rather than stitched to reduce seams and water absorption.
Why do some tournament balls get criticised?
Because very smooth, low-panel-count balls can be aerodynamically unstable at speed, producing unpredictable flight. Manufacturers now texture the surface deliberately to counter it. Shirt materials went through a comparable arc, covered in how football shirts were made before polyester.
