For standard width fabric (45" wide) a twin quilt (63" x 87") will require 5 yards of backing.
Standard King size quilt (120" x 128") = 144 10inch blocks. That does not include any sashing or borders. (Roughly 12 squares across, 12 squares down. Though I'd expand to 13 squares down for aesthetic reasons.)
5/12 of the squares, which is 4+1/12.
There are 4 phonemes in the word "quilt": /k/ /w/ /ɪ/ /t/.
For a "standard" full size quilt (78" x 85") you'll need approximately 440 total squares (20 squares across, 22 squares down).
There are 25 squares on a 5 by 5 checkerboard.
A standard twin mattress measures 39 inches wide and 76 inches long. If you are making a quilt to fit this mattress, you will want to have at least six additional inches on each side of the quilt to cover the sides of the mattress. Those dimensions would then be 51 inches wide and 88 inches long. As 51 cannot be evenly divided by 4, the width dimension needs to be increased to 52 inches. To achieve a quilt 52 inches wide by 88 inches long, each row will contain 13 four inch squares. You will need to make 22 rows.
This will depend on the size of blocks you wish to make. A full quilt measures 78" x 87" (which includes 12" to the left, right and bottom of the quilt so that it drapes over the bed and lays nicely). If you use 12" x12" blocks you will need 42 blocks plus some binding to finish out the edges. If you use 6" x 6" blocks you will need 182 blocks plus some binding to finish out the edges.
