That's an increadibly hard question to answer picking the 50 largest ski resort but I think the list is more or less complete. The top 20 is most certainly the 20 biggest, in the positions after that there might be some resorts that I missed. There are so many of them in that size...
So here is the 50 (there's actually a draw in the positions around 50 so the list has more than 50 resorts) largest linked (piste or lift) ski areas in the world, their piste length in km and country. For the top 19 is also the number of lifts and transport capacity per hour shown.

Ski routes are not included in the table above. If these are included are the piste lengths: 4 Vallées 370 (including the ski route connected La Tzoumaz sector), Matterhorn ski paradise 350, Skiwelt 279, Silvretta arena 238, Serfaus/Fiss/Ladis 204, Hochfuegen/Hochzillertal 188, Laax 220, Sölden 148, Kitzbühel 160, Davos/Klosters 150 and Schladming 117.
For some of these are the "standard" lift pass comprising a bigger area. This list shows the largest (or in some cases several) piste or lift interconnected parts of each ski resort. For most of these are the piste lengths only given for several systems together. In those cases are the piste lengths given calculated from the total piste lengths making them good estimates rather than exact measures. This is true for Sella ronda, 4 Vallées, Matterhorn ski paradise, Avoriaz, Megève, Le Grand Massif, Val d'Allos, Morzine, Zillertal arena, Mayrhofen, Kitzbühel, Davos/Klosters, St. Anton, Schladming and Lech/Zürs.
There is also a number of resorts where the "standard" lift pass give you access to a piste length fitting into this list, but they are actually divided into 2 or more separate systems where each subsystem is too small to fit into the list. Examples of this is Chamonix, Cortina, Zell am See/Kaprun, Gasteinertal and Salzburger Sportwelt.
One more problem associated with making a list of the 50 largest ski resort is that it's very hard to come across piste length data for northamerican resorts. Whistler-Blackcomb does certainly hit the top 50 list and perhaps also Vail. I've tried to figure out the piste lenght for Whistler Blackcomb in several ways:
1. I've gone through the Blackcomb piste map, piste by piste, and compared the piste with the length of the lift beside it and recalculated for the whole resorts giving 160 km.
2. If you take the average of the ratios between the piste length and the number of lifts for the 18 largest resorts and multiply it with the number of lifts at Whistler-Blackcomb you get a piste length of 137 km.
4. The data for Whistler-Blackcomb (area, vertical, no of lifts and transport capacity) is almost identical to Espace San Bernardo with it's 150 km of piste.
Concluding from this Whistler-Blackcomb is estimated to 150 km and by just comparing the Whistler-Blackcomb area with the Vail area, Vail would then be 100 km of piste and not hitting the top 50-list.
An even harder question is the Japanese resorts. The largest linked resort is Mt Naeba which do have 47 lifts (quite a number of systems with fewer lifts are in the list) but the area is much smaller than for example Whistler-Blackcomb so I doubt that it will hit the list. I have not been able to find sufficient information (at least in non-Japanese) to make even a rough estimate of the piste length.
Of course a country comparison would be nice after seeing the list. It looks like this:
1. France 22,5
2. Austria 15,5
3. Switzerland 9,5
4. Italy 5,5
5. Andorra 1
6. Canada 1
Noteworthy is that Andorra beats all countries in the world except the "big four". The Grand Valira system actually extends from Pas de la Casa at the French border in the east to Encamp which is situated in the middle of the country!
