Approximate Shoelace Lengths
Shoelaces are often supplied to fit a certain number of eyelets (eg. 68). 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. 

Accurate Shoelace Lengths
Calculating a reasonably accurate shoelace length for a particular shoe with a particular lacing method requires
taking into account many factors and some pretty complicated mathematics. 

Shoelace Length Calculator
Enter shoe measurements into this webbased calculator to accurately compute the length of shoelace needed for
every possible shoe lacing method on that shoe. 

Shoelace Length Formulas
All of the underlying mathematical formulas from the Shoelace Length Calculator are shown both in mathematical
notation and in generic notation compatible with spreadsheet software like Microsoft Excel. 

Available Shoelace Lengths
Having calculated a theoretically accurate shoelace length, the problem arises of how to buy a shoelace from the
limited lengths available. It all comes down to the resulting end lengths that you find comfortable. 

Comparative Shoelace Lengths
Comparing each lacing method to basic
Criss Cross Lacing makes it easier to know whether a shorter or longer shoelace is needed for a particular
lacing method. 

Excess Shoelace Length
Many shoes nowadays come with shoelaces that are excessively long. Here's some theories about this phenomenon, as
well as some practical solutions as to what to do about it.
