Fabric Calculator: Square Yards, Linear Yards & 10x10 Squares Guide

Crafting & Textiles September 4, 2026 · 9 min read

Cutting quilt blocks, sewing custom curtains, or reupholstering vintage armchairs? When you purchase fabric at a craft store or textile supplier, it is sold in yards. But here is the catch: a fabric store yard is a linear yard, not a square yard.

Depending on the bolt width (44 inches for quilting cotton vs. 54 inches for upholstery), one linear yard contains wildly different amounts of surface area. Two of the most common questions crafters face are: "How many 10×10 squares fit in a yard?" and "How many yards is 42 ten-inch squares?". This guide answers both with clear cutting layouts and an interactive quilt cutting tool.

How Many 10x10 Squares Fit in a Yard?

One linear yard of fabric is 36 inches long. The number of 10-inch squares you can cut depends directly on the bolt's width:

The 10×10 Yield Rule
Standard 44" Bolt = 12 Squares per Yard (3 rows of 4)
54" Upholstery Bolt = 15 Squares per Yard (3 rows of 5)
Cutting Layout

1 Yard of 44" Fabric = 12 Ten-Inch Squares

12 Squares (10"×10") Red borders represent usable salvage scrap (6" end + 4" selvedge)
How Many Yards Is 42 10-Inch Squares?

In quilting, a standard pre-cut bundle is known as a "Layer Cake", which contains exactly 42 ten-inch squares.

  • 42 squares ÷ 12 per yard = 3.5 Linear Yards of 44" fabric.
  • 42 squares ÷ 15 per yard = 2.8 Linear Yards of 54" fabric.
