Size calculator
What size crutches do you need?
Four quick questions. We'll show your fitting numbers, where the grip and cuff generally belong, and which crutches publish a height range that covers you. Then we'll email a printable fitting card you can take to your fitting.

Common sizing questions
What size crutches do I need for my height?
For underarm crutches, two arithmetic estimates from a published comparison of fitting techniques work well as a starting point: your height minus 16 inches, and 77% of your height. For forearm crutches there is no validated height formula, so fit is set from your body: the handgrip goes at the crease of your wrist when your arm hangs straight, and the cuff sits about 1 to 1.5 inches below your elbow.
How high should the handgrip be?
Stand tall with your arm hanging straight down and have someone measure from the floor to the crease of your wrist. That measurement is where the handgrip generally belongs. When the grip is set correctly your elbow should be bent about 15 to 30 degrees while you hold it.
Where should the underarm pad sit?
Not against the armpit. In the published comparison of fitting techniques, ideal crutch length placed the axillary pad about 2.5 inches below the axillary fold, roughly two to three finger widths, so your weight goes through your hands rather than your underarms.
