Winter is the perfect season to settle in and start a new quilting project. A warm quilt, a cup of coffee, and a cozy evening — it doesn't get better than that. If you're planning your first quilt and wondering what a "layer cake" is and how much fabric it contains, you're in the right place.
What Is a Layer Cake in Sewing?
Despite the name, a layer cake in sewing has nothing to do with dessert! It's a precut fabric bundle made up of 10-inch squares — typically 42 squares per bundle — coordinated by color, design, or theme. "Layer Cake" is a trademark term used by Moda Fabrics, though other manufacturers offer similar 10-inch square bundles under different names.
These precut bundles save time, reduce fabric waste, and give you a beautifully coordinated mix of prints right out of the package — perfect for quilters of all skill levels.
How Many Yards of Fabric Are in a Layer Cake?
A standard Moda layer cake contains 42 squares, each measuring 10" x 10". Here's the math:
- 42 squares × 100 square inches each = 4,200 square inches of fabric
- One yard of 44"-wide fabric = approximately 1,584 square inches
- 4,200 ÷ 1,584 = approximately 2.65 yards of fabric total
Keep in mind this is a rough equivalent — the fabric comes in individual squares, not continuous yardage, so how far it goes depends on your pattern and layout.
What Size Quilt Can a Layer Cake Make?
The finished quilt size depends on your pattern, block layout, and whether you add sashing or borders. Here are some general planning guidelines:
-
Throw quilt (~57" x 67"): Sew all 42 squares in a 6×7 layout with no sashing
-
Throw with sashing (~71" x 82"): Same layout with a 2" sashing strip between each block
-
Queen quilt: Plan for at least 2 layer cakes plus background and border fabric
-
King quilt: Plan for 3 layer cakes plus background, borders, binding, and backing
Always follow your specific pattern for accurate yardage — these are estimates to help you plan.
