Sizing Guide

Each Quadtool is custom-made for each person. Measuring your arm is a critical part of the process to ensure a proper fit. Please measure to the nearest 1/8th inch.

Measuring Forearm Length

Measure the distance from the inside of your elbow to your wrist with the elbow and wrist bent.

Measuring Forearm Circumference

Measure around the thickest part of your forearm near the elbow.

Measuring Wrist and Hand Thickness

Download and print The Quadtool Sizing Chart to measure your wrist and hand.

The best method for taking your wrist thickness and hand thickness measurements is to use any kind of clamp.  For the wrist, set the opening of the clamp to just slide over the thinnest part of your wrist, just behind the protruding bone on the outside top of your wrist. For the hand thickness, set the clamp opening to just slide over the middle of your palm. Next, just measure the clamp opening.
