SISU Mouthguard Size Chart
SISU Mouthguard Size Chart
Sizing follows SISU's official Aero size chart. Every size starts flat, moulds to your teeth in hot water at home, and can be remoulded up to 20 times as fit changes or teeth move.
| Size | Athlete Height | Typical Age | Mouth Size | Thickness | Braces |
|---|---|---|---|---|---|
| Small | Under 150 cm (5') | 7+ | Smaller mouths and children | 1.6mm | No (use Medium) |
| Medium | 150 to 180 cm (5' to 6') | 10+ | Average mouths | 1.6mm | Yes |
| Large | Over 180 cm (6') | 13+ | Larger mouths | 2.0mm | Yes |
If you have a larger than average dental arch, consider sizing up; if smaller, size down. With braces, SISU says to use a Medium for children or a Large for adults, fitted with guidance from your orthodontist.
A properly fitted SISU guard feels snug, clicks into place, and lets you speak almost naturally. If yours doesn't, remould it.
