It's all the same block, each with three strips. The color and orientation create the pattern.
There's the center solid square, and then 9 rounds. Looks like it might be 7-8 fabrics.
You can make the squares any size you want; each strip would be a third of that size.
In the picture, I would guestimate the blocks are between 3.75"& 4.5" finished
.
That would create a quilt anywhere from 73"x95" to 87"x114". Actually, if those are 8' ceilings, it's probably the smaller. So strips are cut 1.75" each.
