Многие люди, далекие от футбола, могут подумать, that the soccer ball always has the same size. However, this is far from the case, and if you think so, then you miss many aspects of such a sporting projectile as a soccer ball. Its dimensions can vary very much depending on, for example, for what purposes this projectile serves. In total there are five sizes that do not have any special name, so they are all simply numbered - from the first to the fifth. So, it's time to find out what size a soccer ball can be. Dimensions can be very important for those people who want to professionally engage in this sport. If you play football exclusively in the yard with your friends, then the physical characteristics of the ball for you are unlikely to play a particularly important role.
How can there be such a projectile as footballball? Dimensions begin with the first, and the first is that ball, which has a circumference of 43 centimeters. This is the so-called promotional ball, which is never used for the game. It is created exclusively for advertising and exhibition purposes, so it is always printed a large number of different logos. People who are little familiar with this field of activity, at first they may think that such a ball can not be played. But in fact it turns out that it is produced from all the same materials as the usual game shell. The only difference is the smaller size and weight. Accordingly, if you wish, you can safely play football using this football. Dimensions, of course, do not stop at the unit - ahead of you there are four more different types of balls.
If you are wondering about what sizea soccer ball played in official matches, so far you will not get an answer to it. The fact is that the second size is also often used for advertising purposes, but not as often as the first. The main purpose of these balls is training, especially for beginners, that is, young children. The circumference of the ball of the second size does not exceed 56 centimeters, and its mass is much less than the weight of a full ball - about 280 grams. With such shells, professional football players can also work - but they use them mainly to improve equipment and the level of possession of the ball, which is achieved due to its ease. As you may have noticed, not everyone immediately understands how the size of a soccer ball is calculated. The diameter in the official data is not indicated in the first place - traditionally it is considered to be the length of the circle, so it is indicated specifically, as well as the weight of the ball. These are the two main characteristics that determine the size of the projectile.
This size is also used mainly fortraining of young children, since its dimensions are also small - only 61 centimeters of circumference and 340 grams of weight. Naturally, this is more than the second size, but still not so much to be considered a full-fledged game shell. But of all three sizes, this one is the closest to a full-fledged ball.
This size stands out from the others,because such balls are designed for mini-football. The size of a mini-soccer ball is different from that used for a big game. The length of its circumference does not exceed 64 centimeters, and weight - 440 grams. But in this case there are already limitations on the reverse side of the scale - that is, the ball should be no less than 62 centimeters in circumference and not less than 400 grams in weight. In balls of such a high level, other indicators, such as the pressure inside the projectile, are also checked. Moreover, a number of experiments are conducted on quality control - for example, if the ball falls from a height of two meters, then its rebound should not exceed 65 centimeters, but it should not be less than fifty centimeters. In general, everything becomes much more strictly and clearly.
Well, the last size, as you already couldto guess, is the balls that are used in all official professional football competitions. This ball weighs about 450 grams and has a circumference of 68 to 70 centimeters. Immediately it is worth noting that balls that match this size are the most popular, popular and popular. This is indicated by statistics, thanks to which you can find out that there are more balls of the fifth size each year than balls of four sizes combined. Therefore, most likely, you associate in your head a football with a shell of the fifth size, even when you do not suspect that there are more than one size. But now you are aware that the size of the balls can be different, in accordance with them the shells are used for various purposes. And each of the dimensions is important in its own way.
