Enter the length of the project, the repeat of the pattern, and the extra fabric for error margin into the calculator to determine the fabric repeat.

Fabric Repeat Formula

The following formula is used to calculate the fabric repeat.

FR = (L / R) + E

Variables:

  • FR is the fabric repeat (yards or meters)
  • L is the length of the project (yards or meters)
  • R is the repeat of the pattern (yards or meters)
  • E is the extra fabric for error margin (yards or meters)

To calculate the fabric repeat, divide the length of the project by the repeat of the pattern. Then add the extra fabric for error margin to the quotient. This will give you the total amount of fabric needed considering the repeat of the pattern.

What is a Fabric Repeat?

A Fabric Repeat refers to the section of the design on a fabric that repeats itself. This can be measured both vertically and horizontally. The repeat is determined by the distance between one point in the pattern to the next identical point. Understanding the fabric repeat is crucial in various textile projects to ensure pattern alignment, especially in clothing design, upholstery, or quilting.

How to Calculate Fabric Repeat?

The following steps outline how to calculate the Fabric Repeat.


  1. First, determine the length of the project (L) in yards or meters.
  2. Next, determine the repeat of the pattern (R) in yards or meters.
  3. Next, determine the extra fabric for error margin (E) in yards or meters.
  4. Next, use the formula FR = (L / R) + E to calculate the fabric repeat.
  5. Finally, calculate the Fabric Repeat.
  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 project (L) = 10 yards

Repeat of the pattern (R) = 2 yards

Extra fabric for error margin (E) = 1 yard
