How to measure

Get someone else to measure you if possible, to ensure that the tape is straight. If you are on your own measure a few times and average the measurement. Ensure that the tape is firm, not too tight or too loose.

  • A. Chest
    With your arms at your sides, measure around the fullest part of the bust, keeping the tape level under your arms and across your back.
  • B. Waist
    Find your natural waist by bending to one side to find the crease of your waist. At this point, measure around the waist area.
  • C. Hips
    Measure around the fullest part at the top of hip, with your feet together.
  • D. Inside Leg
    Run the tape measure from the top of the inside leg @ the crotch to the ankle bone.
  • E. Helmet size
    Measure your head at the widest point.
  • F. Hand
    Measure your hand over the knukles.

Motorcycle helmet sizes

Motorcycle helmets should fit snugly on your head even if you've got big hair. Ideally pressure should feel firm and even all over. To find the right helmet size, measure all the way around your head at the widest part from the front of your forehead right around the back of your head and back to the front again, keep the tape measure above your ears and make sure it feels firm but not overtight or too loose.
