Why the difference and is there any way of comparing US and Euro
resorts on size ?

Divide the area by the average piste width and you're done.


Lies, damn lies & ski resort statistics !

All the best,

Actually, take a wild guess about the average piste width, lets say 50
meters. Then the area in hectares (remember those US guys will probably use
acres) divided with 20 is the length of skiing slopes in km.
Best thing you can do actually without more data.
