There are different amounts of pre-cuts depending on the brand, and it depends whether you are seaming them on the short edge or the long edge.
RK rainbow jelly roll has 41 strips that are 44" long. If you pieced only on the long side, your quilt would be 43x164" on the short side would be 86x82". Of course you could always choose to add 2 more strips or crop the edges if you want it perfectly square (actually the strips are not always identical widths anyways so there would likely be cropping regardless).

If you go to the website www.jellyrollfabric.net and sign up, you can download her free e-book on using jelllyrolls. It has a great pdf file for sizing jellyroll quilts. I recommend reading the whole file.

This is really a mathematical question. Assuming you have 40 2.5" strips in each roll.
You will have a quilt either 106 wide by 64 long, or 53 wide by 128 long.
When you do a jelly roll race you are continuously dividing the loooooong strip in half. If you start out with 2 jelly rolls it is approximately 3440 inches long.
You sew it in half once, 1720 x 4.5
Sew in half 2 times, 860 x 8.5
3 times, 430 x 16.5
4 times 215 x 32.5
5 times 107.5 x 64.5 (this is where you normally stop - jelly roll race sewn with .25" seams is 64.5" long)
If you go for one more 53.75 x 128.5
If you want a longer quilt, but still sort of square, you have to use wider strips.
I think I once used 45 - 3" strips to get a quilt 80" long and 60" wide.
Understand, I am a math person and love to figure these things out!!!
Good luck!
