You can make the bricks any size you want. I made a quilt with 6.5 x 18.5" unfinished size bricks. I sorted them into greens/yellows, blues/purples, and browns/blacks/gray. I moved the next row 1/3 of the distance (6" finished)`. And had darker green, lighter green/yellow, darker blue, lighter blue/gray, then brown/black. So my finished quilt was 5 x 18" or a total of 90" wide to be used with overhang on a double bed. I don't remember how long I made it, probably about 98-104".
