The nine patch quilt block is common in traditional, contemporary and modern quilts. Set off the nine patches with sashing, or sew them together to form patchwork. Plan the nine patch block with coordinating or complementary fabrics, or make a block with your scraps for a scrappy nine patch quilt.
How to Calculate Nine Patch Quilt Squares
Because you are sewing same size blocks together, you can make the nine patch block any size without complicated math! Just determine the finished size of your block, and divide by 3 and add 1/2 inch for seam allowances! The calculation is (finished size of block divided by three) + 1/2″ = cut blocks for the nine patch quilt block.
- 3″ finished block, cut 1-1/2″ squares
- 4-1/2″ finished block, cut 2″ squares
- 6″ finished block, cut 2-1/2″ squares
- 7-1/2″ finished block, cut 3″ squares
- 9″ finished block, cut 3-1/2″ squares
- 12″ finished block, cut 4-1/2″ squares
- And so on . . . .
Nine Patch Quilt Block Variations
There are variations of the nine patch quilt block, like the disappearing nine patch, where you make the basic block and then cut them in quarters and sew them back together again. See How to Make A Disappearing Nine Patch Baby Quilt.

Here are four finished nine patch blocks in the same colors.
A layout option is to add sashing between the blocks. Still exploring different options, we do not have to sew them together (yet).
I love vintage linens and quilts. I wish they could tell stories. Here is a strip of vintage nine patch blocks that were carefully cut from a quilt – see the bottom of the block? There is a very small strip of fabric. I will incorporate these into a quilt at some point in time – they are lovely!
