Choosing the right bicycle helmet size is crucial for safety, comfort, and performance. Follow this step-by-step guide to measure your head and select the ideal helmet.
How to Measure Your Head for a Helmet:
- Use a soft measuring tape – Wrap it around the widest part of your head (about 1 inch above your eyebrows).
- Record the circumference – Note the measurement in centimeters (cm) or inches (in).
- Match to our sizing chart below.
Tip: If you don’t have a measuring tape, use a string and measure it against a ruler.
Bicycle Helmet Size Chart

| XS | 44 - 48 cm | 17.3 -18.9 in | 2-5 years old |
S | 48 - 52 cm | 18.9 - 20.5 in | 3-8 years old |
M | 57- 58 cm | 20.5 - 22.4 in | 8-15 years old |
Note: Sizes vary slightly by brand. Check product-specific sizing details.
How Should a Bike Helmet Fit?
✔ Snug but comfortable – No excessive pressure points.
✔ Stable position – Doesn’t shift when you move your head.
✔ Straps adjusted properly – Should form a "V" under your ears with the buckle secured snugly.
Helmet Safety Tips
- Replace your helmet every 3-5 years (or after any impact).
- Always fasten the chin strap securely.
- Avoid buying oversized helmets – safety depends on proper fit!
