For optimum protection your motorcycle gear must fit you correctly. Fortunately, measuring yourself for the right fit is easy. The Sizing Center makes finding manufacturer size specifications easy too. Here’s how…

How to Measure Yourself for Motorcycle Gear

  • Measuring is done the same way for both women and men.
  • Stand naturally with your weight distributed evenly on both feet.
  • It’s easier to have another person measure you but no worries if you need to do it solo. Just take your measurements a couple of times to make sure they’re accurate.
  • When measuring, pull the measuring tape snug — not too loose, not too tight — similarly snug to how you like comfortable clothing to fit.
  • If you don’t have a tape measure use a length of string then measure the string against a ruler.

How to Measure your Hands

Measure your dominant hand with your hand flat on a table and your fingers gently spread.


Wrap a tape measure around your hand at its widest point (or use a length of string then measure it against a ruler). The widest point of your hand is usually across the palm to the web of the thumb.


Measure from the crease at the bottom of your palm where it meets the joint at your wrist, to the tip of your middle (longest) finger.

How to Measure Your Head Size

With a measuring tape (or use a piece of string then measure it against a ruler) measure around your head at its widest points, its largest circumfrence. Generally this will be a circle that angles from just above your eyebrows in the front to slightly below that in the rear.

Different Head Shapes

Among us human beings there are 3 common head shapes: round oval, long oval, and intermediate oval. Certain motorcycle helmet brands fit certain head shapes better than others. A helmet that fits your friend perfectly might be all wrong for you. Stick with the brands that are the best fit for your uniquely shaped noggin.

What is a Correct Motorcycle Helmet Fit?

When trying on a helmet you want it to be snug — not so snug that there are painful pressure points, or that you are biting the inside of your cheeks. Just a gentle, equal, and consistent contact with all parts of your head; firm enough to keep the helmet from sliding around from front to back or side to side.

If you can’t squeeze a finger between the helmet and your head, it’s too tight. If at first a helmet is very slightly too tight that’s ok as the interior padding will compress a little over time and gradually mold to your head. But we are only talking about a small change. Don’t expect a medium helmet to start fitting like a large helmet.

For full face and modular helmets, check that there is enough space between your nose and the front of the helmet. You don’t want your nose to make contact with the helmet.

It goes without saying that no matter which type of motorcycle helmet you wear — open-face, full-face, or modular — when the chin strap is snugly fastened you should never be able to pull the helmet off your head. No way. No how. Ever.

Test it before you use it

Test the comfort of a new helmet by wearing it around your house for a while before using it on a ride. Once you wear a helmet on a ride it can no longer be exchanged or returned.

Customizing the fit

To customize the fit of your helmet, many brands offer a selection of replacement interior padding in various thicknesses.

How to Measure Your Upper Body

Note: Measurements are taken the same way for both men and women.

Neck / Collar

Measure around the thickest part of your neck with the tape measure parallel to the ground. The tightness should be comfortable. Keeping your index finger underneath the tape while measuring can help ensure the fit is not too snug.

Chest / Bust

Stand straight and breath naturally with your arms hanging at your side. Wrap the measuring tape under your arms, parallel to the ground, around the largest part of your chest in the front (above the breasts ladies) and across your shoulder blades in the back. This is measured the same way for both men and women.

For the Ladies: To determine your bust measurement, use the same technique as for the chest but lower the tape slightly to include your breasts.

Waist (for Jackets)

Measure around the narrowest part of your your natural waistline — usually about halfway between your bottom rib and your hips.

(Waist for Pants — see lower body section)


With your arm relaxed (naturally slightly bent), measure from the joint at your collar-bone/shoulder to the joint of your wrist where you would like your cuff to sit. Remember to allow extra length as arms are bent while riding.

Full Sleeve

Measure from the top of the center back (nape of the neck) to the end of your shoulder at the top of your arm. Then measure from your shoulder to just before the wrist bone or where you would like your cuff to sit. Allow the elbow to relax and bend comfortably when measuring.

Add the two measurements together and round up to the nearest available sleeve length.

How to Measure Your Lower Body

Note: Measurements are taken the same way for both men and women.

How to Measure your Waist (for Pants)

Breathing normally and standing equally on both feet, measure around your torso where you like to wear your pants — approximately 2.5” (6cm) under your belly button. Keep tape loosly snug.

(Waist for Jackets — see Upper Body section)


Standing normally with your feet together, wrap the tape around the widest part of your lower hip.


Standing normally and without shoes, measure the inside of the leg from your crotch to just below your anklebone or to the floor. This is most easily done by a friend. Probably more fun that way too.


Standing normally and without shoes, measure the outside of the leg from the top of the waistband to the desired length down the outside side of the leg. Again, more easily done by another person.

How to Measure Your Feet

To measure your feet you will need a sheet of paper bigger than your foot, a pen or pencil, and a ruler or tape measure.

Wear a normal pair of socks, similar to what you will wear in the shoes/boots you are buying.

Step on to the piece of paper and trace around the outside of your foot, then measure using your ruler or tape measure — heel to toe for the length, across the widest part (the ball) of your foot for the width.

Often our feet are slightly different sizes. Trace and measure both feet then go with the larger of the two. Also, it is best to trace your feet in the evening as feet sometimes swell during the course of a day.

When selecting your size, if you are between two sizes always go with the larger. You can always add an insole if needed.

We want you to be happy, so please remember…

Before you wear any new gear on a ride, first wear it indoors around your home for a while (with the tags on) until you are certain it is both comfortable and the correct fit. Once you wear your new gear outside or on a ride it can no longer be exchanged or returned.
