Measure your ski's waist width (the narrowest point under the binding area) and add 5-15mm of clearance. For example, a ski with an 88mm waist needs a 95mm or 100mm brake. The brake arms should clear the ski edge when deployed but not extend so far that they drag in turns. If you're between sizes, go slightly wider—a brake that's a bit too wide creates minor drag, but one that's too narrow won't deploy properly and could leave your ski runaway on the mountain.
