Soccer Ball Sizing Guide

Inflation

Balls should be inflated to 9 - 10.5 psi (pounds of air). This will give you the best performance and bounce.

Match vs Practice balls

Match balls are inspected and have been tested to ensure that they meet strict international match ball standards. FIFA approved balls meet guidelines of circumference, rebound, weight, loss of pressure, and water absorption. To receive the highest rank - FIFA approved - a ball must pass additional tests for shape and size retention. Match balls are great for use in games or in high level training.

Practice balls are highly durable balls, designed to last on all types of fields. They have the best air retention.

Care

Clean and dry the soccer balls after each use. Keep the balls out of extreme conditions like extreme heat, cold, wetness or direct sunlight.

Manufacturers recommend that you reduce the air pressure in your match balls after a game to reduce the amount of stress on the ball seams or stitching.  Be sure to inflate the ball back to proper pressure before the match.    

Construction

Soccer balls are made out of the following materials:

• Bladder
• Lining
• Cover/Casing

Bladder

Bladders hold the air and are at the very center of the balls. They can be made out of Latex or Butyl. Most soccer balls use butyl valves to improve air retention.

Latex used on higher quality balls. They are soft and offer a better touch when playing. They don't hold air as well as butyl and require frequent filling.

Butyl used on practice balls and basic match balls. They hold air very well and don't need to be filled as often as latex bladders.

Lining

Inserted between bladder and cover. It gives the ball the shape, structure, and feel. It ensures a proper bounce.
Lower end balls have two layers of polyester.
Mid level balls have two to three layers of cotton or polyester.
Top level balls have four to five layers of cotton or polyester.

Cover/Casing

The cover material depends on the level of skill. The three most common materials are Synthetic, Polyurethane (PU), and PVC.

Synthetic used for best quality soccer balls. It offers superior feel and softness, but is less durable and less water resistant than other materials. It is the most expensive cover material.

Polyurethane (PU) used for high quality practice balls and basic match balls. It combines the benefits of synthetic materials (great feel and softness) and PVC (highly durable). Feels like leather. Highly scuff resistant, water resistant, and durable.

PVC used for entry-level practice balls. Molded out of plastic with a glossy coating for additional protection. It is the most durable, scuff resistant and water resistant material. Has less softness and feel than the other cover materials. Generally used for the least expensive balls.

Panels

The most common panel configuration is a 32 panel soccer ball. This traditional soccer ball has been used for many years and is still used extensively in international and professional soccer matches.

Other popular designs are with 18 or 26 panels. Fewer panels allows the player to curve the ball more when kicking, because the ball has less stability.

Stitching

Stitches hold the panels together.

Hand Stitching used on mid to top-level soccer balls. Hand sewn balls have tighter and stronger seams. Uses a polyester thread.

Machine Stitching used on low to mid-level soccer balls.

Glue used on low-level balls. Panels are glued directly to the lining. Makes the balls feel harder and is cheaper than stitched balls.
