How to measure
Wind a soft tape measure around the head at its widest point — about the midpoint of the forehead, above the eyebrows. If two sizes both feel comfortable, AGV advises choosing the smaller size. The helmet should feel snug, not painful, with no lateral movement.

AGV publishes SEPARATE charts per model line (shells/interiors differ) — match the chart to the helmet's model. Same label can map to different cm across lines (e.g. L = 59-60 on the Pista/K3/K1 S line vs 60-61 on K6/K5 S). Some lines split medium into MS/ML. AGV prints cm only; inch values converted (cm ÷ 2.54, 0.1" rounding). Labels normalized (XXS/XXL/XXXL → 2XS/2XL/3XL). No youth chart published. Verified verbatim from agv.com 2026-07-13.
