Measure your head's circumference with measuring tape


A helmet only protects you when it fits right. Before you order, take a moment to measure your head — it takes less than a minute and makes all the difference.

  1. Take a soft measuring tape (like one used for sewing)
  2. Position it about 1 cm above your eyebrows
  3. Wrap it around the widest part of your head
  4. Make sure the tape is snug but not tight
  5. Note your measurement in centimeters

Stuck between sizes?

We offer two sizes: XS/S (51–56 cm) and M/L (55–61 cm). If you measure 55 cm and have a deeper head shape, go for the M/L.

Every helmet comes with on extra tick padding. Swap it to dial in the fit.

Don't have a measuring tape lying around?


Grab a phone cable, string and your mobile phone. They'll do the job just fine.

  1. Grab a piece of string or a phone charging cable
  2. Wrap it around your head 1 cm above your eyebrows
  3. Mark where the string overlaps
  4. Lay the string flat on the table
  5. Open the measurement app on your phone
  6. Measure the length in centimeters

A note for parents

For children aged 5 and up, our small size (51-56 cm) should fit well. Always measure your child's head before purchasing, as head sizes can vary considerably among children of the same age. SafeFit adapts as your child grows.

Fit matters. So does wearing it.
