The most efficient and accurate method for piecing a square in a square involves some waste. With this method however, you will be able to easily and accurately make any size square in a square without resorting to a Square in a Square Calculator for the cutting measurements, either online or in some remote reference material. Follow along as I take you through the precision technique basics of piecing a square in a square.
Crunching the Numbers
This method uses a large center square and four small, corner squares. The large center square is cut ½” larger than the finished measurement of the unit. For example if you wanted a 4” finished unit, you would cut the center square 4½” (4 + ½ = 4 ½).
Piecing it Together



Step 7: To add corner triangles to a square that does not need to be a specific size, you will first need to determine the unfinished size of the unit. To determine the unfinished size of the unit, multiply the square by 1.414. For example, the house square measures 5½”. Multiply this number by 1.414 to equal 7¾”. The unfinished size of the unit is 7¾”.
