Fabric Calculator

Estimate the fabric length to buy for a sewing project.

How the Math Works

The Fabric Calculator uses the formula length = area ÷ fabric width to determine how much fabric you need. This works by dividing the total area of your project by the width of the fabric you're using. For example, if your project requires 10 square feet of coverage and your fabric is 2 feet wide, you'll need 5 feet of fabric length. The calculation ensures you account for the entire surface area while using the fabric's standard width to avoid overbuying or running short.

Practical Applications

To apply this calculation, first measure the total area your project will cover (such as a quilt, curtain, or cushion cover). Next, check the fabric width listed on the bolt or label—this is typically between 42-60 inches for most fabrics. Input these values into the calculator to determine the required length. This method is especially useful for complex projects where you need to layer fabrics or account for seams and pattern matching.

Day-to-Day Use

This calculator simplifies everyday sewing and crafting tasks, helping you buy the right amount of fabric for projects like curtains, tablecloths, or children's clothing. It prevents costly mistakes from purchasing too little fabric or wasting material with excess. Whether you're a beginner starting your first project or an experienced crafter planning a large quilt, the tool saves time and money by providing precise measurements tailored to your fabric's width.

Worked example

5,000 in² on 44 in fabric → ~3.16 yards.
