The key dimension in a suspension corrected fork, is the
crown to axle distance. When you measure yours be sure to use the loaded dimension for your fork, which occurs when you're sitting on the bike in riding position. Then either lock the fork there so you can measure off the bike, or have a friend measure for you while you're on the bike.
Odds are you won't match this perfectly, so go for the nearest match. If you're in the middle between 2 choices, let handlebar height decide. If you're near the top of the bar height, or have lots of spacers under the stem, go long to raise the bar a bit, or if you have no spacers, and want a lower bar, go shorter.
