How many 5'' squares does it take to make a queen size quilt?

In order to make a queen-sized quilt using 5-inch fabric squares, you need a minimum of 336 squares. Most standard charm packs, or pre-cut 5-inch fabric squares, contain 42 pieces, so eight charm packs can be sewn together to make a queen-sized quilt.

Most queen-sized quilts measure approximately 84 x 92 inches, which includes the quilt drop on all sides of the mattress, and 336 squares should be an ample number of blocks to complete a quilt top, depending upon the pattern used. If you only want to make a quilt to fit the mattress of a queen-sized bed, which would be approximately 60 x 80 inches, then 192 squares cut at 5 inches are needed.
