Choosing the right size bike helmet is important for ensuring top-level protection and comfort while riding. While different types of helmets have varying characteristics–extended coverage for MTB, aerodynamic and lightweight for road, style for commuting, ease of use for kids–the most important function is to protect your head. So, be sure to find the right size before your next helmet purchase, and then dial in the fit so it fits snugly and can protect you better in the event of a crash.

Measure Your Head for a Lazer Bicycle Helmet 

Place two fingers (approximately equivalent to two centimeters) above your eyebrows and measure the circumference of your head at this height. A tailor's tape is the easiest tool for the job, but a traditional tape measure and piece of string or shoelace also works fine. Record the number and measure again to double-check your work. As the old saying goes: measure twice, order once!

Select the Right Size Lazer Helmet

Using the measurement for the circumference of your head, refer to the size charts for each helmet found on the Lazer website. Select the helmet that your measurement aligns with. Thanks to the micro-adjustable fit systems on all Lazer helmets, each size is designed to fit a wide range of head shapes. But wait! What if you’re on the fence between sizes? We recommend going with the smaller of the two sizes.

Fine-Tune Helmet Fit with Lazer's Retention System

Lazer helmets are designed to fit the majority of riders who fall within the given size, and the fit can be fine-tuned to each head using Lazer's retention systems. Each model comes with one of four main head baskets and dial adjustment designs that complement the intended purpose of the helmet. The retention systems provide evenly distributed pressure around the circumference of the head to secure a helmet in place without creating pressure points. The result is a highly customizable fit that comfortably secures the helmet in place.

Don't fret. Lazer has a 60-day Satisfaction Guarantee. If the helmet doesn't feel like you thought, exchange or return it without hassle.
