Enter the length and width of the shoe, and the constant K into the calculator to determine the shoelace length. This calculator can also evaluate any of the variables given the others are known.

Shoelace Length Formula

The following formula is used to calculate the shoelace length.

SL = 2 * (L + W) + K

Variables:

  • SL is the shoelace length
  • L is the length of the shoe
  • W is the width of the shoe
  • K is a constant that accounts for the extra length needed for tying the shoelace

To calculate the shoelace length, multiply the length of the shoe by 2, add the result to the product of the width of the shoe and 2, then add the constant K.

What is a Shoelace Length?

A shoelace length refers to the length of a shoelace, which is typically measured in inches or centimeters. The length of a shoelace can vary depending on the type and size of the shoe it is intended for. For example, a running shoe with many eyelets may require a longer shoelace than a casual shoe with fewer eyelets. The shoelace length is important to ensure that it is long enough to lace up the shoe securely, but not so long that it becomes a tripping hazard.

How to Calculate Shoelace Length?

The following steps outline how to calculate the Shoelace Length using the given formula:


  1. First, determine the length of the shoe (L).
  2. Next, determine the width of the shoe (W).
  3. Next, determine the constant that accounts for the extra length needed for tying the shoelace (K).
  4. Next, substitute the values of L, W, and K into the formula: SL = 2 * (L + W) + K.
  5. Finally, calculate the Shoelace Length (SL).
  6. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge:

Length of the shoe (L) = 10

Width of the shoe (W) = 5

Constant for extra length (K) = 2
