Approximate Shoelace Lengths
Approximate Shoelace Lengths Shoelaces are often supplied to fit a certain number of eyelets (eg. 6-8). This is a VERY rough way to estimate the required length, as shoes can vary widely. Allowing for the shoe width, or using my approximation formula, gives much better results.


Allowing For Shoe Width
How Wide Are Your Shoes?
Wide shoes require much longer shoelaces than narrow shoes with the same number of eyelets. The following tables therefore have separate columns for Narrow, Medium or Wide shoes. The lengths have been calculated using my Shoelace Length Calculator, and are based on typical shoes laced with standard Criss Cross Lacing and tied with an average sized Shoelace Knot.

Length Approximation Formula
The above tables were worked out using my Shoelace Length Calculator, which uses some fairly exact formulas. However, it's not always convenient to look up this web site, nor to carry a printout of the above tables.

The alternative is my Shoelace Length Approximation Formula:
Horizontal Spacing (in mm) × Total Eyelets + 500 mm
For example, on a typical sneaker with a horizontal spacing of 50 mm and with six pairs of eyelets (12 eyelets total), the approximate shoelace length would calculate as follows:
50 mm × 12 (eyelets) = 600 mm, + 500 mm = 1,100 mm (110 cm)
Note that this approximation will generally come up a little short. For slightly more accuracy, add about 3 mm to the horizontal spacing measurement:
50 + 3 = 53 mm, × 12 (eyelets) = 636 mm, + 500 mm = 1,136 mm (114 cm)
Lug Lacing diagram For shoes with lugs instead of eyelets, add the lug width to the horizontal spacing measurement. For example, on a typical sneaker with a horizontal spacing of 50 mm and with five pairs of lugs (10 lugs total), and with each lug about 8 mm wide, the approximate shoelace length would calculate as follows:
50 + 8 = 58 mm, × 10 (lugs) = 580 mm, + 500 mm = 1,080 mm (108 cm)
NOTE: For those who still use imperial measurements, use 2 inches instead of 50 mm, 20 inches instead of 500 mm, and 1/8 inch instead of 3 mm.
