How to Know Your Helmet Size?

Before getting a helmet fitted, it is imperative that you know your helmet size. Especially for larger-than-average heads as most helmets do not have a size range of more than 59cm and instead feature removable padding and an adjustable fitting system.

Bike Helmet Size Guide

If you’re unsure on how to size your head, here’s a step-by-step guide:

  • Take out a tape measure, not the ‘wall measuring’ kind but the soft, fabric ones as they are more pliable and give accurate readings.
  • Stand in front of the mirror and for better measure, get a friend to supervise.
  • Wrap the tape measure around the circumference of the head i.e the widest part of the head as this is where the helmet will sit. Usually it is right above the ears and an inch above the eyebrows.
  • Make sure to bring the tape measure around to the front so the reading can be clearly seen.
  • Write down the reading in inches as well as centimetres as sizing charts can have measurements listed in either of those. 

If there isn’t a tape measure available, fret not because there is an easy way to measure your head size. Take a piece of yarn or a thick string and wrap it at the circumference of your head. Now, mark where it ends and measure the length using a basic ruler.

Always make sure to have these measurements ready and recheck the sizing chart’s range multiple times for good measure as one brand’s small can be another’s medium. Also, make sure to read the customer reviews as some helmets may need to be sized up.

How to Fit a Bike Helmet?

A common confusion among cyclists is that a helmet’s sizing and fitting criteria is the same i.e a helmet that is sized proportional to the head will fit correctly. This is generally untrue. 

Where getting the correct size of helmet means it may be designed for your head shape, fitting the helmet correctly means it will be positioned right on your head, feeling snug and light.

There’s no doubt that a well-fitting helmet is a safer helmet because when the helmet is snug, it reduces the wind drag, prevents the helmet from flying off and protects the head from harsh impact energy.

bike helmet fit

Here’s how you can fit a helmet correctly:

  • Adjust the dial-fit. Most helmets, nowadays, feature a dial system which allows cyclists to fit the helmet by turning a dial.
  • If there’s no dial, use the pads inside to customise the shape of the helmet. For narrow heads, add in pads on the side and for smaller heads, add one on the back. Large-sized heads can move the pads around and leave a few gaps for optimal air circulation.

Always make sure the helmet is level on the head. You’ll know it fits correctly if it’s hard to chew gum, when you look up the front rim is barely visible, the Y of the side straps sit below the ear and the chin strap is snug at the neck.

Frequently Asked Questions

What is the largest size in bike helmets?

On average, you can easily find a bike helmet that has a size range up to 66cm. Since larger-sized heads are relatively uncommon, bike helmets are usually manufactured in a universal fit with features to accomodate all head sizes. Ski and motorcycle helmets usually have size ranges up to 72cm.

Are MIPS helmets bigger?

No, MIPS helmets aren’t bigger or bulkier because weight and size of the helmet is determined by the material used and its form factor respectively. MIPS is a safety technology which benefits the cyclist by providing greater impact protection and does not add to the weight of the bike helmet.

How do I know if my helmet is too small?

When a helmet is too small, it won’t go past your ears and if it does, it will be quite an uncomfortable fit, become a source of headaches, cause neck strain and a red forehead. Also, it won’t provide healthy ventilation which can cause heat exhaustion and a sweaty mess.

Do helmets get looser over time?

Yes, most helmets need 15 to 20 hours to break in which is why it’s recommended to go for a helmet that fits snug and is a tad bit close-fitting, it will loosen with time. The general rule of thumb is that a new helmet will make chewing gum difficult.

After going through this comprehensive guide, you’re one pedal closer to zeroing in on the perfect helmet for your large-sized head and sizing it perfect to your proportions for best safety!
