Finished vs. unfinished quilt block sizes

When finished block is indicated as 6.5" is that the size prior to putting quilt together or after it is put in the quilt. Like should it first be 7"?


It sure can get confusing!

Yes, the unfinished size is the actual size of the block from raw edge to raw edge after you have pieced it and before you have assembled it into the quilt.

If the pattern says the block is 6.5" finished, its unfinished measurement is:

6.5" + .5" = 7" unfinished

That extra .5" is for the seam allowances that will disappear into the seam once the blocks are joined.

Thank you for your question. I'm working on some new patterns and because of it, I'll be adding both finished and unfinished block sizes for greater clarity for the reader. Thank you!

Challenging block size!
by: Linda Lou

This is very challenging! I have followed the pattern to a "t" and when I see the sashings on I am going to barely have enough material for the seam. So sad to put all this effort in and hope your seam stays in🤔

finished vs unfinished quilt blocks sizes.

So if a pattern says it is a finished 6" block and they give you all the cutting measurements. It then is a 5.5" block when trimmed?

PS You are right, very confusing.

From the Editor: No. If the block is 6" finished, that's the size that shows after it is pieced into your quilt top.

To stitch it into your top you need to have a 1/4" seam allowance on each side. Add 1/2" to the finished size (6" + 1/2"); it is a 6-1/2" UN-finished block.

The unfinished size is always larger than the finished size because of the seam allowances needed to 'finish' it.
