1) How do I measure my head circumference before ordering a helmet?

I. Preparation Before Measuring

  • Prepare a soft measuring tape.
  • If you don’t have one, you can use a string, then measure its length with a ruler afterward.
Head Measurement Guide

II. Measuring Steps

Step 1: Position the measuring tape
Wrap the measuring tape around the widest part of your head, usually about 1 cm above the eyebrows and around the most prominent part of the back of the head.

Step 2: Ensure the fit
Keep the tape level and snug—not too tight or too loose. You should be able to fit one finger between the tape and your head.

Step 3: Read the measurement
Read the number where the tape overlaps. Measure several times and take the average value to ensure accuracy.

2) How do I know which size fits me?

III. Common Questions

What if my measurement falls between two sizes?
If your head circumference is between two sizes, we recommend choosing the larger size. You can fine-tune the fit using the inner padding, while a helmet that is too small may cause pressure and discomfort.
