Short answer: the Laws of the Game do not set a minimum size in centimetres for shin guards. Law 4 says they must be made of a suitable material, be of an appropriate size and be covered by the socks, and that players are responsible for the size and suitability of their own shin guards. So Law 4 does not ban mini shin guards as such, but nobody can promise you they are "legal everywhere". The referee inspects equipment before the match, and your league or club can add its own rules. If in doubt, ask the referee or your club before kick-off.
We sell mini shin guards at TrincheBalk. That is exactly why we would rather show you the rule as it is written, with sources, than tell you what you want to hear.
What Law 4 actually says
The Laws of the Game are written by IFAB, the International Football Association Board. In the 2026/27 edition, Law 4 lists shin guards as compulsory equipment.
Law 4 of the Laws of the Game (IFAB) requires shin guards, fully covered by the socks. It asks for a suitable material and an appropriate size, and makes players responsible for the size and suitability of their own shin guards (IFAB, Laws of the Game 2026/27, Law 4).
Three things follow from that:
- They are compulsory. Shin guards are part of the compulsory kit, with a shirt with sleeves, shorts, socks and footwear.
- They must be covered by the socks. That applies to every shin guard, mini or full size.
- "Appropriate size" is not a number. There is no minimum in centimetres, and the responsibility sits with the player.

Who decides on match day
Law 4 says players must be inspected before the start of the match and substitutes before they enter the field. If a player wears unauthorised or dangerous equipment, the referee orders them to remove it. With no minimum size in the text, the call on the pitch belongs to the referee.
One more detail for small pads: a player whose shin guard is lost accidentally must replace it as soon as possible and no later than when the ball next goes out of play. Keep them in place with shin guard adhesive straps, or with grip socks and a sock sleeve on top.
Your league's own rules
We did not verify league-by-league rules. Check your league handbook or ask your club.
Checklist for playing by the rules
- Fully covered by the sock for the whole match.
- Held in place with adhesive straps, or with grip socks and sock sleeves on top.
- The right size. Most of our mini shin guards come in 8, 10 and 12 cm: 8 cm is super minimal, 10 cm is the balance, 12 cm gives more coverage. The EVA foam ones come in 9x6 or 15x9 cm and the Carbon Look only in 10 cm.
- Ask first if you join a new league or a tournament with its own rules.
