Stilo sizes are head circumference in centimetres — a size 57 helmet is built for a 57 cm head. Measure around the widest part of your head, about 1 cm above the eyebrows and above the ears.
Stilo run a little smaller than most other brands. If you fall between sizes, or measure a number Stilo does not make (53 and 62 are not produced), take the next size up and tighten the fit with cheek pads (20–35 mm) or crown and earmuff fitment pads.
Not every model offers every size: the ST5 range skips 56 and 58, the ST6 range skips 60, and the Venti Sport helmets are offered in 54, 55, 57, 59 and 61 only. Check the size selector on the product.
Shell sizes: ST5 and ST6 use a small shell for 54–59 and a large shell for 60–64.
Where dealers quote letter equivalents: 55 = S, 57 = M, 58 = M/L, 59 = L, 60 = L/XL, 61 = XL, 63 = XXL, 64 = XXXL. Stilo itself sizes only by number.
Sizing is from the manufacturer and varies between brands. Measure yourself and compare against the table rather than ordering your usual street size.
