Football / soccer — FIFA Equipment Regulations 2025
Back shirt number 25–35 cm high for men and 20–35 cm for women, stroke width 2–5 cm. Front shirt and shorts numbers 10–15 cm high, stroke 1–3 cm. Player name in letters 5–7.5 cm high, above the number. The number must contrast sufficiently with the surrounding colour and be clearly legible. UEFA sets the same figures and adds that a number must stay legible from at least 50 metres, with number 1 reserved for the goalkeeper.
US high school basketball — NFHS
Front number at least 4 inches, back number at least 6 inches, stroke at least three-quarters of an inch on both. Legal numbers are 0, 1–5, 00, 10–15, 20–25, 30–35, 40–45 and 50–55 only, and a roster cannot carry both 0 and 00. A single solid colour, clearly contrasting with the jersey body.
US high school football — NFHS 2025
Front number at least 8 inches, back number 10 inches with a stroke of about 1.5 inches, the same colour and style front and back and clearly contrasting with the jersey. Numbers 0 to 99, and a number written with a leading zero such as 07 is illegal. NCAA football matches these heights almost exactly. NCAA basketball changed in 2023–24 and now permits any number from 0 or 00 through 99, so the old restricted list no longer applies there — check your current rulebook rather than an old kit.
The manufacturer’s logo is also capped
FIFA allows a maker’s mark of no more than 20 square centimetres on the chest, on each sleeve and on the shorts. NFHS and NCAA allow a single logo inside two and a quarter square inches. We do not put our name on your gear at all, in any size, so the allowance stays yours to spend on a sponsor.
The most common reason a kit gets sent back is not colour. It is a number that does not meet the competition’s specification. Send us the competition you play in and we set the artwork to its rule before you approve the sample.
