How To Size a Snowboard (Plus Boots and Helmets)

Follow simple steps to figure out what size snowboard to ride, how your boots should feel on your feet, and how your helmet should sit on your head.

Key Takeaways

• The length of your snowboard depends mainly on your height and weight. Heavier or taller riders usually ride longer boards, while lighter or shorter riders ride shorter ones.
• Your snowboard boots should feel snug with your heel locked in place and just a little room for your toes.
• A snowboard helmet must be snug and sit low on your forehead to protect you if you fall.

Do you know how to size a snowboard so it actually feels natural under your feet? You might be drawn to gear that looks cool or matches how you express yourself, but if it’s the wrong size, you’ll have a harder time on the mountain. Getting the fit right from the start means you’ll spend your time actually snowboarding, not fussing with uncomfortable boots or wobbling on a board that doesn’t feel right. 

How Do You Size a Snowboard Properly?

If you’re shopping through an online sportswear store, checking a specific brand’s size guide is the best way to ensure a great fit. But if they don’t have a chart, follow these steps. 

Know Your Weight

Your weight determines how much board you actually need under your feet. Snowboards are designed to flex and respond based on how much pressure the rider puts on them. If the board is too small for your body, it can feel unstable and shaky. If it’s too big, it can feel stiff and hard to control.

Most snowboard brands publish sizing charts that match your weight range to a recommended board length in centimeters. This information is especially important to know when looking for youth sizes, as younger riders need a board that responds easily to their lighter frames. If you can’t find a brand’s size chart, use these measurements:

• Under 110 lbs: 135–145 cm
• 110–130 lbs: 140–148 cm
• 130–160 lbs: 146–155 cm
• 160–180 lbs: 152–160 cm
• 180–200 lbs: 157–165 cm
• Over 200 lbs: 160–170+ cm

If you’re between two sizes, both will usually work. The difference comes down to how you ride.

Stand the Board Up Beside You

Next, stand the snowboard upright next to you on the floor, with the tail touching the ground. For most beginner riders, the top of the board should land somewhere between their chin and their nose. This range usually means the board is long enough to stay stable but not so long that it’s hard to turn.

Know Your Riding Style

How you plan to ride plays a big role in choosing the right board length. Even if two people are the same height and weight, they might choose different board sizes depending on what they want to do on the mountain.

• To ride faster, carve down groomed runs, or float better in deeper snow, a slightly longer board can feel more stable.
• To learn basic turns, ride slowly, or practice tricks and jumps, a shorter board is often easier.

If you’re brand new to snowboarding, you’re better off choosing something that’s easy to maneuver rather than ultra-stable at high speeds. You can always size up later as your confidence grows.

Measure the Snowboard’s Width

A snowboard’s width doesn’t come in only one size. The board needs to be wide enough so your boots sit properly on it without hanging too far over the edges.

If your board is too narrow, your boots may stick out past the sides. When that happens, your toes or heels can catch in the snow during turns, which can slow you down or even cause you to fall.

On the other hand, if the board is too wide, it can feel harder to turn because you have to work more to get the edges into the snow. To help riders avoid these issues, most brands offer boards in different widths based on boot size:

• Men’s boot size 8–10: Standard width
• Men’s boot size 10.5–12: Wide board
• Men’s boot size 12+: Extra-wide board

Checking the board’s recommended boot size range is an easy way to avoid one of the most common mistakes snowboarders make.

How Should Snowboard Boots Fit?

Snowboard boots are one of the most important pieces of gear you’ll buy. They’re the only thing connecting your body to the snowboard, so if they don’t fit right, turning, balancing, and even standing up can feel uncomfortable.

Measure Your Foot

Snowboard boots don’t just use regular shoe sizes. Most brands use something called mondo sizing, which is based on the actual length of your foot in centimeters. To find that number, you’ll need to measure your foot:

1. Take off your shoes and socks.
2. Place a piece of paper flat on the floor against a wall.
3. Stand on the paper with your heel touching the wall and your weight evenly on your foot.
4. Use a pencil to mark the tip of your longest toe.
5. Measure the distance from the wall to the mark using a ruler or tape measure.
6. Write that number down in centimeters.

Measure both feet, because one is often slightly bigger than the other. Use the longer measurement when choosing your boot size. That number in centimeters is your mondo size. For example, if your foot measures 26 cm, you’ll usually start with a mondo 26 snowboard boot.

Try Them On

Once you have boots in your size, it’s time to check how they actually feel on your feet:

• They should feel snug all the way around, including the sides and top of your foot.
• Your heel should stay locked in place when you bend your knees or lean forward. If your heel lifts, the boots are too big.
• Your toes may lightly touch the front of the boot when you stand straight. When you bend your knees into a riding position, your toes should pull back slightly and feel more comfortable.
• There should be no sharp pain, numbness, or pressure points. Snug is good, but painful is not.

A good test is to flex forward like you’re riding. If your foot slides around inside the boot, the fit is too loose.

How Should a Snowboard Helmet Fit?

A snowboard helmet’s main job is to protect your head, but it can only do that if it fits correctly. A helmet that’s too loose can shift during a fall, and one that’s too tight can cause headaches and distract you while riding. 

Measure Your Head

Helmet sizes are based on head circumference, not hat size. Here’s the proper way to measure your head for a helmet. 

1. Grab a soft tape measure (the kind used for sewing). If you don’t have one, use a string and measure it with a ruler afterward.
2. Wrap the tape around your head so it sits just above your eyebrows and ears and around the widest part of the back of your head. 
3. Read the measurement where the tape meets.

Use that number to find your size on the helmet’s size chart. If you’re between sizes, most people are more comfortable sizing up and adjusting the fit using the helmet’s padding or dial system.
