Find instructions and advice on how to properly measure and fit a new helmet for your childFinding and fitting a new helmet for your kid can be a difficult and time consuming task. We've consolidated a lot of helpful information below to help you measure your kids head, find the correct size helmet to purchase, and then make sure the helmet sits properly on his or her head. The Bottom Line is this - don't assume head size based on age or perception. Grab a quick (and easy) measurement to significantly improve your task of getting the correct kids helmet for your son or daughter.
How to Measure Your Kid's Head for a Helmet
Whether you're looking for a kid's skateboard helmet, kid's BMX helmet, kid's ski helmet, or other sport-specific helmet, the same measurement principles remain.
Measuring for a Kid's Helmet with a Measuring TapeMeasuring your child's head (or anyone else's head) for a helmet is pretty simple. Simply take a tape measure and wrap it around his or her head, about an inch above the eyebrows, keeping the tape measure level all the way around. Use the centimeter side of the measuring tape to get a more accurate measurement.
Measuring for a Kid's Helmet with a Piece of String
If you don't have a measuring tape, take a piece of string and wrap it around your child's head, about an inch above the eyebrows. Mark or cut the string so you get an accurate measurement. Then place the string next to a ruler on a flat surface to see how long it is (in centimeters).
Is Your Kid's Helmet Too Small?
- It's sitting on top of your child's head
- It's so snug that it leaves a line on his/her forehead
- It's so snug that your child cannot put on a pair of glasses
Is Your Kid's Helmet Too Big?
- It wiggles or flops around when you turn your head.
- It tilts backward or is sliding to the side.
Another way to check the size is, after buckling the helmet, have the wearer open his/her mouth. If the helmet doesn't press against the forehead, it is too big.
How to Adjust Helmet Fit with Fit Pads
You can customize the fit and sizing of a helmet either through fit pads or a dial-in adjustment on the back of the helmet. (For instance, Giro helmets feature a number of dial-in fit systems. We cover just about all of Giro helmet fit systems in this article.) If your helmet uses fit pads, it will probably include them in three varying thicknesses--very thin, medium, and very thick. The pads easily Velcro in and out of the interior of the helmet. An adjustable fit system or using fit pads are really the only safe way to allow your child to "grow into" a helmet.
A Properly Fitted Kid's Helmet
- Fits snugly but comfortably
- Does not wobble or slide around
- Rests level on the wearer's head, not perched on top of the head, tilted back, or resting on the eyebrows
- Feels secure
Aren't Kids' Helmets Sized According to the Child's Age?Age is not a reliable measure of head size. There is just too much variation in the size and shape of little kids. One eight-year-old could fit an adult "Medium" while another child the same age would need a child's extra small. Always size a child's helmet by measuring the head circumference, not by the age of the child. Did you know:
- 95% of kids up to 8 years old will fit in a 54cm or smaller helmet
- 50% of kids up to 13 years old will still fit a 54cm helmet
- 54cm is the average head size of a 12 year old
