Standard Comforter Sizes and Number of 4” Squares
Needed to Make a Patchwork Quilt

(sizes are approximate-please measure your bed to determine the proper size)

• Crib (42 x 50 inches): 12 squares across by 14 down, 168 squares total
• Twin/single (69 x 90 inches): 20 squares across by 26 down, 520 squares total
• Full/double (84 x 90 inches): 24 squares across by 26 down, 624 squares total
• Queen (90 x 96 inches): 26 squares across by 28 down, 728 squares total
• King (104 x 96 inches): 30 squares across by 28 down, 840 squares total

Note that the number of squares cited above assumes ¼” seams and no borders. If using a border, you can subtract 2 squares from each dimension for 3.5” of border. For example, for a twin size (69 x 90 inch) quilt with a 3.5” border on all 4 sides, it would require 18 squares across by 24 squares down (a total of 18 x 24 or 432 squares).

To figure out the number of squares for a different size quilt, follow this example for a quilt top with a finished measurement of approximately 60 x 70 inches. For a 4 inch square, subtract the seam allowance (1/4” x 2 = ½") to figure the finished square size; in this case, 3.5”. Divide each measurement by 3.5 to figure the number of squares across and down. For the example quilt, 60/3.5 = 17.14 (round it to 17 squares across and your quilt top will be just a little bit smaller than 60”) and 70/3.5 = 20 squares down. The total number of squares needed will be 17 x 20 or 340 squares. If you are planning on a border, remember to account for it by subtracting the border measurement from the overall desired dimension of your finished quilt (if you have a 5 inch border, you’d subtract 2 x 5, or 10” from both dimensions since your border will be on all 4 sides of the quilt).

You can use the example above for other square sizes: for 5 inch squares, use 4.5, and for a 6 inch square, use 5.5 for the finished square size.
