If your quilt has blocks set on point, it will have triangular openings around the outer edges of those blocks where each diagonal row of blocks ends.
You will need two sizes of triangles to fill in the blanks. One size fills in the gaps along the top, bottom and sides of the quilt. Four smaller triangles are used to create the quilt corners.
Corner triangles are half-square triangles, created by cutting a square in half once diagonally to produce two triangles with the straight grain on their short edges.
Side setting triangles are quarter-square triangles, created by cutting a square in half twice diagonally to produce four triangles with the straight grain on their long edges.
To calculate the size of the two squares, start with the finished parent block size times 1.4142. For the corner squares, divide this by 2 and add 0.875". For the side triangles' squares, add 1-1/4" to step 1.
Unless you have experience with these setting triangles, it is recommended that you add 1/4" to 1/2"; you can trim off any excess after assembling the blocks and triangles.
if you have an iPod, iPhone, or iPad you can down load this app call QuiltRef and it give you this information. You cn also plug in you block size and it does the math for you. I would recommend making the triangles bigger and then square up the block.
