Fabric Repeat Calculator

Formula

To calculate the fabric repeat:

\[ FR = \left( \frac{L}{R} \right) + E \]

Where:

\( FR \) 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)

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.

Example Calculation

Let's assume the following values:

Length of Project \( L \) = 10 yards
Repeat of Pattern \( R \) = 2 yards
Extra Fabric for Error Margin \( E \) = 0.5 yards

Step 1: Divide the length of the project by the repeat of the pattern:

\[ \frac{L}{R} = \frac{10}{2} = 5 \]

Step 2: Add the extra fabric for error margin:

\[ FR = 5 + 0.5 = 5.5 \text{ yards} \]
