AGV Helmets Size Guide Official head circumference charts (cm) with inch conversions
Measure head circumference with a soft tape at the widest point — midpoint of the forehead, just above the eyebrows. Keep the tape level and snug. Use the largest of two measurements. Match your number to the model family below, not just the size letter.

- Measure: tape around the head at the widest point, midpoint of the forehead, above the eyebrows.
- Fit: helmet should sit level with even pressure on the crown. Cheeks should feel firm. With the strap fastened, the helmet should not slide independently of your skin.
- Between sizes: AGV sport helmets often fit snug. Confirm the exact model family — K6 S and K6 do not use the same size letters.
Fit notes: Centimeter ranges are from the official AGV US size guide. Inch values are conversions for reference. Charts differ by model — use the table that matches the helmet you are buying. This is a sizing reference only and does not guarantee a perfect fit. Do not ride in a helmet that is loose or rocks on the head.
