Shoelace Length Calculator

Count the total number of lace holes on one side of your shoe. That number is your eyelet pair count. For example, if there are 6 holes on the left side and 6 on the right, you have 6 eyelet pairs. Most standard sneakers have 5-7 pairs, dress shoes have 3-5 pairs, and boots can have 7-10 pairs.

The Straight Bar (European Straight) pattern generally uses the least amount of shoelace, as it avoids diagonal cross segments. However, it can be harder to tighten evenly. The Criss-Cross pattern is the most popular and uses a moderate length. Ladder lacing typically requires the most length due to the extra wrapping at each rung.

Using the correct shoelace length prevents tripping hazards from excessively long laces, avoids the frustration of laces that are too short to tie properly, and ensures a secure, comfortable fit. The right length also reduces wear and tear on both the laces and the eyelets.

Absolutely! Boots and hiking shoes typically have more eyelet pairs (7-10) and slightly wider spacing. Use the Boot preset for a quick starting point, then adjust the horizontal and vertical spacing to match your specific boots. For heavy-duty boots, consider choosing a larger bow size since thicker laces require more length to tie comfortably.

Flat laces stay tied more securely due to increased friction, making them ideal for athletic shoes. Round laces slide more easily through eyelets and are often preferred for dress shoes and boots. Round laces may require about 5-8% extra length compared to flat laces for the same shoe because they tend to slip and need a slightly larger bow to stay tied.

This calculator provides a highly accurate estimate based on geometric calculations of the lacing path. Results are typically within 1-3 inches of the ideal length. We recommend rounding up to the nearest available standard length (e.g., if you get 58 inches, choose a 63" lace for comfort). Individual preferences for bow size and lace material can slightly affect the optimal length.

Most shoes have an even number of eyelets (paired left and right). If your shoes have an odd number, it usually means one side has an extra hole — common in some skate shoes. In this case, count the smaller number as your eyelet pairs and add 0.5 to account for the offset. The calculator will still give you a very close estimate.

We recommend always sizing up to the next standard length. Longer laces can be double-knotted or tucked in, while laces that are too short simply won't tie. An extra inch or two is far better than coming up short. The calculator's recommendation already accounts for this best practice.
