Ski Length CalculatorRace Ski Length Calculator
In racing, ski length is not a fit question — it is a legality question. The FIS sets minimum lengths (and, except in slalom, minimum sidecut radii) for every discipline, and this calculator returns them by discipline, sex and rule set, with the band racers actually choose in practice.
Race Ski Length Calculator
Race sizing is the opposite of recreational sizing: the rules set a floor, and athletes ski at or just above it. Choose your discipline, sex and whether you race under senior FIS rules or FIS Masters rules, and the calculator returns the legal minimum, the band racers actually ski, and the minimum sidecut radius where one applies. Recreational skiers who ended up here by mistake want the chart-based calculator instead.
How it's calculated
The minimums are taken from the FIS Specifications for Competition Equipment as tabulated in the FIS rules and cross-checked against the peer-reviewed summary in the journal Frontiers in Physiology (Burtscher et al., Table 2) and an independent race-equipment guide — all three agree exactly. Senior minimums: slalom 165 cm (men) / 155 cm (women); giant slalom 193 / 188 with a minimum radius of 30 m; Super-G 210 / 205 with radius 45 m (men) / 40 m (women); downhill 218 / 210 with radius 50 m. Lengths are developed lengths, measured per ISO.
Masters racing differs: under the FIS Masters rules the minimums are recommendations rather than hard limits — except Super-G, where the Masters minimum (185 cm men / 180 cm women) is mandatory — and Masters giant slalom allows a further 5 cm tolerance. There is no Masters downhill event, so the calculator declines that combination rather than inventing a figure. Racers with no length restriction (women 55+, men 65+ in Masters) don't need this page's minimums at all.
The 'typical' band — minimum plus 0–5 cm (0–7 in downhill) — is not a rule but race-room practice: extra length is stability at speed, bought a few centimetres at a time. Junior categories (U14/U16) carry their own equipment rules in the FIS documents and are not modelled here; check the current FIS specifications for your age group.
Why race skis are sized by rulebook
Recreational sizing balances comfort: length trades turning ease against stability, and the skier picks a point. Racing removes the choice from below. The FIS equipment specifications exist because the incentives point the other way — left alone, speed-event skiers would trade safety for grip and agility, and technical skiers would take slalom levers into giant slalom. The minimums (and the radius floors that arrive with GS and grow through Super-G to downhill) are the federation fixing the stability side of the trade by law.
That is also why the 'typical' bands on this page hug the minimums so closely: in slalom the minimum is optimal for almost everyone; in the speed events, a few centimetres above the floor buys course-specific stability, and no more, because the rest is bought with radius and construction instead.
Worked example
A woman entering FIS giant slalom: the legal floor is 188 cm with a sidecut radius of at least 30 m — ski 187 cm and the skis fail equipment control, whatever her height or weight. In practice she will choose between 188 and about 193 cm depending on the course set. The same skier in slalom drops to a 155–160 cm ski: the minimum is 155 cm and there is no radius rule at all, because a slalom ski's job is the opposite of a downhill ski's.

| Discipline | FIS minimum — men | FIS minimum — women | Minimum radius | Masters minimum — men / women |
|---|---|---|---|---|
| Slalom | 165 cm | 155 cm | No minimum | 165 / 155 cm |
| Giant slalom | 193 cm | 188 cm | ≥ 30 m (men) / 30 m (women) | 185 / 180 cm |
| Super-G | 210 cm | 205 cm | ≥ 45 m (men) / 40 m (women) | 185 / 180 cm |
| Downhill | 218 cm | 210 cm | ≥ 50 m (men) / 50 m (women) | No Masters event |
Senior minimums from the FIS Specifications for Competition Equipment (lengths are developed lengths, measured per ISO). Masters figures are recommendations in the FIS Masters rules — except Super-G, where the Masters minimum is mandatory — and Masters giant slalom allows a further 5 cm tolerance. There is no Masters downhill. Racers commonly ski the minimum itself in slalom and a few centimetres above it in the speed events.
What this calculator won't do
It won't size junior racers — U14 and U16 equipment rules are their own tables in the FIS specifications, with maximum as well as minimum lengths, and they change as age groups roll. It won't size Para alpine sit-skis and outriggers, which the FIS Para Snowsports equipment specifications govern separately. And it won't talk you out of the minimum: at FIS level, a ski 1 cm under is a disqualification found at equipment control, not a fitting preference.

Frequently asked questions
What is the FIS minimum length for slalom skis?
Men 165 cm, women 155 cm — with no minimum sidecut radius, the only discipline without one. In practice almost everyone races exactly the minimum (a rare few men take 170 cm): slalom rewards the shortest legal lever, so the floor is also the answer.
What is the FIS minimum for giant slalom?
Men 193 cm, women 188 cm, with a minimum sidecut radius of 30 m for both. Racers typically ski 193-198 cm (men) — the minimum is both the legal floor and, for most, the working length.
Why does the FIS mandate such long skis for Super-G and downhill?
They are the price of survival at speed. A downhill ski at 130 km/h must track straight, absorb terrain, and resist twisting — length and a long sidecut radius are how a ski does that. The progression tells the story: as speeds rise from slalom to downhill, minimum length rises 165 → 193 → 210 → 218 cm and minimum radius appears and grows 30 → 45 → 50 m.
Does my height matter for race ski length?
Only the length and radius floors in the FIS Specifications for Competition Equipment. Your height and weight choose where inside the typical band you ski (and your coach's eye counts for more), but no chart overrides the minimum: a 187 cm GS ski is illegal for a woman at FIS level however perfectly it fits her.
Are Masters racers bound by the same minimums?
Under FIS Masters rules the minimums (slalom 165/155, GS 185/180 with 5 cm tolerance, Super-G 185/180) are recommendations, not mandates — except Super-G, where the minimum is compulsory. There is no Masters downhill. Women 55+ and men 65+ have no length or radius restrictions at all in Masters racing.
