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.

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.

Sewing the Square in a Square Quilt Block Together

Take each of your small squares and draw a line from one corner to the other.

Place one of the small squares face down on the main fabric square lining it up in one of the corners as shown in the image below. Take a second small square and do the same thing on the opposite side of the block. Sew along the lines you drew.

Cut off the excess fabric on each side leaving a quarter inch seam.

Press the flaps open.

Take the remaining two squares and repeat the process on the other two corners of the main fabric piece.

This is what the reserve side of the block looks like.

And this is the completed block.
