Quilt Binding Yardage Calculator

Formula

Yardage = Total Binding Length + (Seam Allowance × Number of Strips)

Formula Breakdown

The process of calculating quilt binding yardage depends on the quilt’s dimensions and the width of the binding strips. Below are the general guidelines for common systems:

1. Perimeter-Based Yardage

To calculate binding yardage based on the quilt’s perimeter:

Binding Yardage = (Quilt Perimeter ÷ Usable Strip Length) × Strip Width

For example:

If the quilt has a perimeter of 200 inches , the usable strip length is 40 inches , and the strip width is 2.5 inches , the calculation becomes:

Binding Yardage = (200 ÷ 40) × 2.5 = 12.5 inches

In this case, you’ll need approximately 12.5 inches of fabric .

2. Fabric Width Adjustment

To adjust for fabric width:

Adjusted Yardage = Total Binding Length ÷ Fabric Width

For example:

If the total binding length is 250 inches and the fabric width is 42 inches, the calculation becomes:

Adjusted Yardage = 250 ÷ 42 ≈ 6 yards

In this case, you’ll need approximately 6 yards of fabric .

3. Seam Allowance Inclusion

To account for seam allowances:

Final Yardage = Total Binding Length + (Seam Allowance × Number of Strips)

For example:

If the total binding length is 200 inches , the seam allowance is 0.5 inches , and there are 5 strips , the calculation becomes:4

Final Yardage = 200 + (0.5 × 5) = 202.5 inches

In this case, the final yardage is 202.5 inches .

How to Use the Formulas

Let’s break down the process step by step:

Step 1: Identify the Input Values

Determine the values you need for the formula. For instance:

• If you’re calculating yardage for a quilt with a perimeter of 180 inches , note the quilt dimensions.

Step 2: Apply the Conversion Formula

Use the appropriate formula based on the available data. Using our example:

Binding Yardage = (180 ÷ 40) × 2.5 = 11.25 inches

Step 3: Add Adjustments

Always include adjustments for fabric width, seam allowances, or design modifications to ensure sufficient fabric.

Practical Applications

FAQs

What Is Quilt Binding Yardage?

• Quilt binding yardage refers to the total amount of fabric required to bind the edges of a quilt, measured in yards or inches.

Why Do We Need to Calculate Quilt Binding Yardage?

Calculating yardage ensures sufficient fabric for binding, avoiding shortages or excess material.

Can I Use This Chart for Other Projects?

Yes, similar principles apply to other crafts like garment sewing or upholstery, but specific adjustments may be needed.

Tips for Accurate Quilt Binding Yardage Calculations

1. Use Standardized Charts : Always refer to official conversion charts for accuracy.
2. Account for Fabric Variations : Some fabrics may have unique widths or textures.
3. Add Seam Allowances : Include extra fabric for seams, hems, and errors.
4. Test with Samples : Create small mock-ups to verify calculations before cutting fabric.

Examples

Example 1: Fabric Width Adjustment

You have a total binding length of 300 inches and a fabric width of 42 inches . Using the formula:

Adjusted Yardage = 300 ÷ 42 ≈ 7.14 yards

You’ll need approximately 7.14 yards of fabric .

Example 2: Seam Allowance Inclusion

You have a total binding length of 250 inches , a seam allowance of 0.5 inches , and 6 strips . Using the formula:

Final Yardage = 250 + (0.5 × 6) = 253 inches

You’ll need 253 inches of fabric .
