Cutting calculations for a Square in a Square Quilt Block

The square in square requires 1 large square and 4 small squares to be cut.

1. To determine the size of the large square decide on your finished block size and add ½”.

For example, our finished block size is going to be 4 inches so we simply add ½” to that which equals 4½”.  So our large square will be cut at 4 ½”.

2. To determine the size of the 4 small squares divide the finished block size by 2 and add ½”.

For example, our finished block size is 4 so we divide it by 2 which gives us 2″. Then we add a ½” to that. So our small blocks will be cut at 2½” each.
