Which Giant size am I?
Measure your head first (tape or string around the widest part, 1-2 cm above the eyebrows), then read it off the table above — Giant sizing is not the same as the next brand's. Across the range, Giant covers 49 to 63 cm (19.3 to 24.8 in). If your measurement falls outside that, no Giant helmet we track will fit you.
