Yardage For Sofa Cushions

Yardage for Sofa Cushions: A Guide to the Perfect Fit

Creating custom sofa cushions that fit perfectly and provide the desired level of comfort and support requires careful consideration of yardage. The amount of fabric needed depends on several factors, including the cushion's size, shape, and style. This guide will provide a comprehensive overview of yardage requirements for different types of cushions, ensuring you have ample fabric to complete your project successfully.

Rectangle and Square Cushions

For rectangular and square cushions, determine the fabric yardage based on the following measurements:

Length (L): Measure the cushion from one end to the other along the longest side.
Width (W): Measure the cushion from one edge to the other along the shortest side.
Height (H): Measure the cushion's thickness from top to bottom.

Yardage Formula: 2L x W + 2L x H + 2W x H

Example: For a cushion measuring 24"L x 18"W x 4"H, you would need approximately 2 x 24 x 18 + 2 x 24 x 4 + 2 x 18 x 4 = 202 inches of fabric.

Round and Oval Cushions

For round and oval cushions, determine the yardage based on the following measurements:

Diameter (D): Measure the distance across the widest part of the cushion.
Height (H): Measure the cushion's thickness from top to bottom.

Yardage Formula for Round Cushions: 3.14 x (D/2)^2 + 3.14 x D x H

Yardage Formula for Oval Cushions: 3.14 x (L/2) x (W/2) + 3.14 x ((L+W)/4) x H

Example: For a round cushion with a diameter of 20" and a height of 4", you would need approximately 3.14 x (20/2)^2 + 3.14 x 20 x 4 = 635 inches of fabric.

Bolster Cushions

For bolster cushions, determine the yardage based on the following measurements:

Length (L): Measure the cushion from end to end.
Diameter (D): Measure the cushion's diameter at its widest point.

Yardage Formula: 3.14 x D x (L + D)

Example: For a bolster cushion measuring 20"L and 8"D, you would need approximately 3.14 x 8 x (20 + 8) = 471 inches of fabric.

Additional Considerations

In addition to the above yardage calculations, factor in the following considerations:

Seam Allowances: Add 2-3 inches per seam for hems and seams.
Pattern Matching: For patterned fabrics, additional yardage may be required to match patterns.
Fabric Shrinkage: Pre-wash and iron fabrics before cutting to account for potential shrinkage.

With accurate yardage measurements and careful planning, you can create sofa cushions that fit perfectly and provide lasting comfort for your living space.
