Sportswear & Football Kit Size Guide

When ordering your new football kit or any items from our selection of sportswear, your first question should always be what size do I need? Whether you’re looking for just a football jersey, a single pair of shorts or the full kit, getting the sizing right will ensure you’re comfortable and able to move freely whatever activity.

In order to help you select the right size for you or someone else, for example when you’re ordering on behalf of your child or a team, follow the size guide we’ve put together below. All you’ll need is a tailors tape measure and a pen if you’re writing your sizes down as you go. Please note, both our adult size guide and our junior guide are measured in inches.

Junior Size Guide

While some junior football kits and sportswear are bought according to age, there is no better way than to  measure junior players for their kits as kids differ in height and chest measurements more than age sizing allows. Instead, the junior football kits and sportswear at Avec Sport are sized in the same way as the adult  with measurements around the chest, waist and inside leg. Find the right kit or sportswear for your child or junior team in the junior size guide below.

Football Kit Size Guide FAQ

What size football kit for a 10+ year old?

While the Avec Sport junior football kit size guide is not sized according to age, if you’re ordering for a large group of junior players and can’t get accurate measurements for them all, using their age to find the average height and measurements is a useful alternative. At 10 years old, for example, the average height is 138cm for boys, making the best football kit size for a 10 year old an MJ at Avec Sport.

Please note, while this method works for ordering the average football kit sizes by age, it’s recommended that accurate measurements be taken to ensure each child’s football kit fits as well as possible.

What size football kit for a 6+ year old?

In a similar way to above, taking the average height of a 6 year old in the UK is a quick and easy way to figure out roughly the right size football kit for this age. In the UK, the average height for this age is 115.5cm, meaning the best football kit would be an XSJ at Avec Sport.
