Did your roll have 40 strips in it? If you do the math, it should turn out that size with 40 strips.
40strips x 40" = 1600" x 2.5"
fold once- 800" x 4.5"
fold again- 400" x 8.5"
fold again- 200" x 16.5"
fold again- 100" x 32.5"
last fold - 50" x 64.5"
Add borders and voila' you have a quilt!
Hope that helps.
