Snowboard size calculator
Weight drives this more than height does, which is why most chin-height rules give poor advice.

What size snowboard do I need?
Weight is the primary factor, because it determines how the board flexes. A 70 kg all-mountain rider sits around 154 cm, with roughly four centimetres either side as a sensible range. Park riders size down and freeriders size up. Boot size decides the width, which matters just as much.
The chin-height rule is bad advice
For decades the standard guidance was that a board should reach somewhere between your chin and your nose. It persists because it is easy to remember, and it ignores the thing that actually matters.
A snowboard is a spring. It is engineered to flex a certain amount under a certain load, and that load is your weight. Two riders of identical height can differ by 30 kilograms, and the same board will feel stiff and unresponsive under one and washed-out under the other.
Height still contributes, because a very tall rider on a short board has an awkward stance width relative to the effective edge. The calculator uses weight as the base and adjusts modestly for height rather than the other way round.
Width is where toe drag comes from
Length gets all the attention and width causes most of the actual problems. If your boots overhang the edges far enough to touch the snow during a hard carve, the board washes out — and no amount of correct length fixes it.
That is decided by boot size, not by height or weight. A rider with size 12 feet on a standard-width board will drag regardless of how well the length suits them.
Wide boards exist precisely for this, and mid-wide options have become common. The calculator flags which category your boot size points to.
How the recommendation is built
A weight base, adjusted for height and style.
base length from rider weight50–57 kg → 145 cm 72–82 kg → 157 cm57–64 kg → 150 cm 82–91 kg → 160 cm64–72 kg → 154 cm 91–100 kg → 163 cmheight adjustment ±4 cm for unusually tall or short ridersstyle adjustment park −4 cm freeride +4 cmwidth from boot size, in mondo centimetres
The style adjustment reflects genuine physics rather than fashion. A shorter board has less swing weight and spins more easily, which is why park riders size down. A longer board has more effective edge and more surface area, which gives better float in powder and more stability at speed.
Camber profile matters too and is not modelled here. A rocker board rides shorter than its length suggests, so many riders size up a few centimetres on full rocker.
Worked example: a 75 kg all-mountain rider
A rider weighing 75 kg, 178 cm tall, with size 27.5 mondo boots, riding all-mountain.
- Base from 75 kg157 cm
- Height adjustmentabout +1 cm
- Style adjustment (all-mountain)0
- Recommended length158 cm
- Width from 27.5 mondomid-wide
About 158 cm in a mid-wide board, with 154 to 162 a sensible range.
The same rider heading into the park would drop to around 154, and a dedicated powder setup would push toward 162. One rider can reasonably own boards eight centimetres apart.
What else changes the answer
- Rocker profiles ride shorter than their length; many riders size up on full rocker
- Stiff boards demand more rider input and suit heavier or more aggressive riders
- Splitboards are usually sized slightly longer for touring float
- Beginners often benefit from the shorter end of the range while learning to turn
- Manufacturer weight ranges vary — check the specific model before buying
Common questions
Should a snowboard reach my chin?
It is a rough guide at best. Board length should be driven by weight, because flex is engineered around load. Two riders of the same height can differ by 30 kg, and the same board will suit only one of them.
What size snowboard for 70 kg?
Around 154 cm for all-mountain riding, with roughly 150 to 158 as a sensible range. Park riders would look at the shorter end and freeriders the longer end.
How do I know if I need a wide board?
By boot size rather than height or weight. Mondo 29 and above generally needs a wide board, and 27.5 to 29 is worth a mid-wide. If your boots overhang enough to touch the snow in a hard carve, the board will wash out.
Should I size up or down for powder?
Up. A longer board has more surface area and floats better, and the extra effective edge adds stability at speed. Four centimetres over your all-mountain length is a reasonable starting point.
Does board length matter for beginners?
Yes, and shorter is usually easier. A slightly shorter board turns more readily and is more forgiving of imprecise input, which shortens the time spent catching edges. Sizing at the bottom of the recommended range is sensible for a first board.
