If there are 40 strips in each, the 1600 inches you start with finishes at 40 x 80 or so. 4 jelly rolls would yield about 80 x 80, if you use the same number of "turns" as the original pattern.

Oops, the actual number are different than above. The original size is 48 x 64 using one jelly roll. If you use 4, you will start with 6400 inches. Sew once, and it is 4" x 3200", twice it's 8"x1600", three times 16" x 800"' four is 32"x 400", 5 is 64" x 200", 6 is 128"x100", less the seam allowances. the seam allowances will use about 12" from the width and. 4" from the length, so 116x96 or so. Sounds about right for a queen, stripes going side to side.

A jelly roll strip 2-1/2 x 42 yields about 82 square inches. A queen quilt 100 x 100 needs 10000 square inches. 10000/84 equals a smidge over 119 strips. You'd need about 3 jelly rolls to make a queen size. Might be fun to make the center out of the small baby quilt 1600 and then log cabin the rest of the rolls around that, mitering all the corners.
