Kids Bike Helmet Size Chart

A properly fitting helmet is essential for safety and comfort while riding a bicycle. Follow these steps to ensure you select the right size helmet for your child. 

Step 1: Measure Your Head

Use a flexible measuring tape to measure the circumference of your child's head. Place the tape measure slightly above the ear, across the mid-forehead, and completely around the head, about 1 inch above the eyebrows. If you don't have a measuring tape, use a string and measure it against a ruler.

Step 2: Choose Your Helmet

Consult the size chart below to find the appropriate helmet size based on the head circumference measurement.

How a Kid’s Helmet Should Fit

1. Position: The helmet should sit level on your child’s head, not tipping forward or backward. The front of the helmet should be two fingers' width above the eyebrows.
2. Adjustment: Use the retention mechanism (often a ratchet dial) to snugly fit the helmet around the head. The chin strap should be snug but comfortable.
3. Comfort: Trim or tuck away any excess strap material to prevent irritation.

What to Look For in a Kid’s Helmet

• Safety Standards: Ensure the helmet meets Snell B90/B95 standards.
• Visor: Consider a helmet with an integrated visor for sun protection.
• Padding: Focus on the fit rather than the thickness of internal foam padding.
• Style: While style is important, prioritize function and fit.

By following these guidelines, you can ensure that your child’s helmet provides the best possible protection while riding their bike.
