How to choose and size snowboard bindings

Binding size is chosen from your snowboard boot size. Burton’s binding size guide explains that bindings come in sizes such as small, medium and large, each covering a range of boot sizes, and that there are “small differences” between brands. So the only reliable answer comes from the chart for the exact model you are considering.

1. Get your boots right first. Know your boot brand and size, ideally after a proper fitting. Our boot fit guide covers what a good fit feels like.
2. Open the binding model’s size chart on the manufacturer’s website or product page.
3. Find your boot size in the same system the chart uses: US, UK, EU or Mondopoint. Men’s, women’s and kids’ charts are often separate.
4. Pick the size whose range includes your boot. If you sit at the boundary between two sizes, try both with your boots on, or ask the brand or a shop which fits your boot model better.

What a binding size chart looks like

As an example, Union’s Atlas Pro product page (checked 23 September 2026) lists these men’s/unisex ranges:

This is one model from one brand. Other brands, and sometimes other models from the same brand, draw the lines in different places, so never use this table to size a different binding.

If your board came with bindings already mounted, or you found a used pair, check their size before you buy boots or ride them.

1. Look for a size marking on the baseplate, heelcup, highback or under the footbed. Many bindings print S, M, L or a boot-size range.
2. Identify the brand and model from the highback or straps, then look up that model’s size chart. Older models may be listed in the brand’s manual archive or support pages.
3. Test with your own boots. Strap in and run through the fit checks below. If the boot will not sit centrally, the straps will not reach, or the boot moves around, the binding is the wrong size for that boot.

Measuring a binding with a tape is not a reliable way to work out its size, because every brand builds its baseplates and heelcups differently. If there is no marking and you cannot identify the model, a snowboard shop can help. Buying a whole setup second-hand? Our used board inspection checklist covers what else to look at.

Mounting pattern

Burton’s size guide says that “almost all snowboard bindings are compatible with almost every snowboard,” with the main caveat that adapter discs may be needed. The four main patterns are 4x4, 2x4, 3D and Burton’s The Channel.

• Check the board’s specs for its pattern.
• Check the binding’s description or manual for the patterns and discs it supports.
• Watch for single-system formats. Burton’s EST bindings, for example, are made for The Channel.

Board width

Burton’s snowboard buying guide says waist width is the best single guide to which boot and binding sizes a board will take. When your boots stick out well past the edges with the bindings on, your toes or heels can drag in turns. Check the board maker’s boot-size guidance, and see our board size and width guide if you are still choosing a board.

Once you know the bindings fit, mounting them is the next job. Our step-by-step mounting guide walks through it.

Binding flex, sometimes called response, describes how stiff the highback and baseplate feel. Brands rate it on their own scales, so compare within one brand where you can. Burton’s size guide links flex to rider weight and style: softer bindings suit lighter riders and a playful feel, while stiffer bindings give heavier and more aggressive riders more support.

• Softer: forgiving, easier to twist and press, often chosen for park riding and by many beginners.
• Medium: a common all-mountain choice.
• Stiffer: quicker edge-to-edge response and more support at speed, often chosen for freeride and carving.

Try to keep boots, bindings and board in a similar flex range. A very stiff binding on a very soft board, or the reverse, can feel unbalanced. Our board-buying guide explains board flex in more detail.

Other features to compare

• Straps and ratchets: easy to use with gloves on.
• Highback adjustment: forward lean and rotation settings.
• Footbed and toe ramp: some models let you change support under the boot.
• Entry style: traditional two-strap, rear-entry or step-in.

Step-in systems let you click in without straps, but they only work with boots made for that system, and the sizes must match. Burton’s size charts state that Step On bindings “are ONLY compatible with Step On boots,” and warn that “pairing incompatible size boots and bindings will result in malfunction and could compromise your safety.” Its Step On overview explains that the bindings come in sizes matched to boot size ranges.

• Buy boots and bindings from the same system.
• Match the binding size to the boot size on that system’s own chart.
• Check the binding’s mounting works with your board.
• Practice clicking in and out at home before your first run.

1. Your boot size falls inside the model’s size range on its own chart.
2. The bindings support your board’s mounting pattern, with the right disc included.
3. Your boots sit centered and snug in a trial fit, with strap adjustment to spare.
4. The flex suits your ability, weight and riding style.
5. For step-in systems, boots and bindings are from the same system and matched sizes.
6. You know the retailer’s returns policy before you mount anything.

If you are buying for a child, kids’ bindings have their own charts. See our guide to sizing kids’ gear.
