Crunching the Numbers
You can obtain eight half-square triangles from a single square by first by adding 1 inch to the finished measurement of the half-square triangle and then multiplying that number by 2. For example, if you wanted to make eight 2-inch finished half-square triangles you would need a 6-inch square (2 + 1 = 3 x 2= 6”).Piecing It Together

This series is extremely helpful!!
Thankyou
I have such a hard time doing the math trying to fit half square triangles into a square to try to piece together like flying geese around the square. This I think might be helpful for me
When you are referring to the “finished size”, does that mean that this is the actual size of the units when done cutting, or does it refer to a block that includes the extra 1/2″ required to piece it to other blocks? Thank you for the clarification!
Hi Dawn,
This refers to the size that the block will be once it is sewn into a quilt. So for example, a block that is 6 1/2″ when you construct it will finish at 6″ in the quilt.
