Quilt Math: Enlarging and Reducing Block Size

By Deb - Quiltblox on March 10, 2024March 10, 2024

I make a lot of quilt blocks, I’m guessing that you do too. There are times though, when I want to make a block a different size that I have the instructions for. Changing the size of the block isn’t hard to do, but the math can be a little tricky to have to figure out every single time I want to do it.

So … if I’m going to change the size of a quilt block, how do I figure out what the correct percentage is to get the size block I want? I’ve created a chart for that.

The math has already been done – I’ve created the chart below for enlarging and reducing the size of our quilt blocks. This chart is the latest addition to my Quilt Math series of charts and guides – helping you with some of that troublesome math.

Just click on the image or the button below it to open the file and print out a copy.

The chart above is one example of the charts and guides I’m adding to the – QUILT MATH section of this website, under the LEARN tab at the top of any page on the website.

I have a few more to add, but several useful charts are included in QUILT MATH right now. You can print them out and have them handy for when you need to refer to them. I hope you find them to be as helpful as I do!

I do have another “secret weapon” for changing the size of a block. The Quick and Easy Block Tool provides sizing options (with the math already done) for 110 different traditional quilt blocks. I’ve been using this handy spiral-bound book for years!
