Choose a cross-country ski size range
Estimate cross-country ski length from height, weight, ski style, and flex needs. Use it as a starting point before checking the manufacturer weight chart.

Default worked example
Salomon’s general height starting context adds 20–30 cm for classic or 10–15 cm for skate to height. It is context only: bodyweight and the exact product flex/size chart determine the fit. No generic backcountry length is calculated.
How to use the calculator
Enter height in inches, bodyweight and style. Use the general height context only to begin checking the exact product chart. No generic backcountry range is available.
What the result means
Compare this starting range with the exact product chart; it is not a fitted size. Salomon says bodyweight is the primary cross-country sizing factor and the exact model size/flex chart should determine the selection.
Formula and units
Height cm = inches × 2.54. Salomon’s general height context adds 20–30 cm for classic, or 10–15 cm for skate. Weight and flex labels are context and do not add invented centimeters.
Worked examples
Height (in): 68 in; Weight (lb): 160 lb: Height (in): 68 in; Weight (lb): 160 lb; Ski type: classic; Flex needs: standard.
Example result: Height starting range: 192.7–202.7 cm; Height in centimeters: 172.72 cm; Entered skier weight: 160 lb; Style: classic; Entered flex context: standard.
Height (in): 102 in; Weight (lb): 240 lb: Height (in): 102 in; Weight (lb): 240 lb; Ski type: skate; Flex needs: standard.
Example result: Height starting range: 269.1–274.1 cm; Height in centimeters: 259.08 cm; Entered skier weight: 240 lb; Style: skate; Entered flex context: standard.
Limitations and common mistakes
Model, camber, flex, skill and bodyweight can override the height range. Check the exact manufacturer chart or a fitter before purchase. The source itself gives general starting advice, not a validated universal fitting equation.
Do not buy a ski from height alone or treat a generic soft/stiff label as a fixed length adjustment.
Sources and assumptions
The manufacturer height guide supplies starting context, not a fitted recommendation. Bodyweight and exact product flex/length charts override it.
