Sports Gear Size Calculators

Find the right ski, snowboard, surfboard, boxing glove, tennis racket and golf club size for your height, weight and level.

Ski Size CalculatorEnter your height, weight, ability and the kind of skiing you do to get a recommended ski length range and where it sits against your body.Snowboard Size CalculatorGet a snowboard length range for freestyle, all-mountain or freeride riding, and find out from your boot size whether a regular, mid-wide or wide board fits.Ski DIN CalculatorLook up the reference DIN (release value) for your weight, height, age, skier type and boot sole length in the ISO 11088 chart – for understanding only, never for adjusting bindings yourself.Surfboard Volume CalculatorWork out how many litres of volume you need from your weight and skill, then see which board type and length to look for in the waves you surf.Boxing Glove Size ChartEnter your weight, what the gloves are for and your sex to get a glove weight in ounces, with the usual rules for amateur and professional bouts.Tennis Racket Size ChartFind the right racket length for a child, or the head size, weight, balance, grip size and string tension that suit an adult’s level and swing.Golf Club Length CalculatorCombine your height and wrist-to-floor measurement to see how much longer or shorter than standard your clubs should be, with a lie angle starting point.

Why size matters

Skis that are too long or a stiff snowboard make turning hard for beginners, while gear that is too short feels unstable at speed. Glove weight in ounces protects both your hands and your training partner; 14–16 oz is the usual choice for sparring. Racket grip size and string tension affect comfort and elbow health.

Use calculators as a starting point

Size charts combine height, weight, ability and riding or playing style into a range. The DIN setting on ski bindings is safety-critical: the calculated value is for information only and must be set by a qualified ski technician. Trying equipment before buying is always worth it.
