Assuming the 9-patches are 3" FINISHED, then the border square-in-a-square blocks would be 4.25" FINISHED.
(FINISHED size x 1.414" to get the FINISHED on-point width of a block)
The inner border width is 2.25" FINISHED.
Using those measurements, the quilt top would be ~ 85"x103" when fully assembled.
