Canoe paddle sizing is generally based on a paddler's torso length and which position he or she is paddling from. Bow paddlers generally use shorter strokes, and find shorter paddles easier to work with. Stern paddlers and solo boaters need a slightly longer paddle to assist in controlling the direction of the canoe. A general guideline for paddle sizing for a bow person is a paddle that measures from the floor up to the middle of their chest. Stern and solo paddlers will find a paddle that stands up to their collarbone are generally a better fit.
