Shoelace Length Calculator

Enter shoe measurements into this web-based calculator to accurately compute the length of shoelace needed for any possible shoe lacing method on that shoe.

Instructions

Measure the lacing area of your shoe (as per the diagrams);
Select the closest measurements in the drop-down selection boxes;
Select the desired lacing method (default = “Criss Cross Lacing”);
The resulting shoelace length will be calculated automatically.

NOTE: More info on the required shoe measurements P, H, V, W and L:

NOTE: These calculations are theoretically accurate, but in practice they will be out a little depending on the accuracy of any approximations, the diameter of the eyelets, depth of the eyelets, variations in distances between eyelets, thickness of the laces, elasticity of the laces, how tightly they are laced, how complex a knot is used, the curvature of the top of your foot, even the thickness of your socks!
