This site shows how to make it and, at near the bottom of the page, is a link to purchase a "Technique Sheet" for $7 that gives you cutting instructions for blocks in 21 sizes.

It really is amazing the different names for the same block. Then the differences in the quilts using the same block.

The Grandmothers Choice Pdf shows measurements for four different finished sizes from 4" to 8" It appears that Technique Sheet is for finished sizes from 2" to 12" by half inch increments. Just for fun I did a spreadsheet for the measurements.
For the 2" Finished =
Cream rectangle size – (cut 2) 1.5" x 2.5"
Colored square size – (cut 2) 1.5" x 1.5"
Colored rectangle size – (cut 1) 2.5" x 3.5"
And for the 12" finished =
Cream rectangle size – (cut 2) 6.5" x 7.5"
Colored square size – (cut 2) 6.5" x 6.5"
Colored rectangle size – (cut 1) 12.5" x 14"
