Use the following formula if the size you want is not on the table above:

BLOCK SIZE WANTED (divided by) CURRENT BLOCK SIZE = PERCENT TO ENLARGE OR REDUCE
Example:
To enlarge: Size you want = 12" and Current size = 4"
12/4=3 (answer times 100 = 300%)
To reduce: Size you want = 7" and Current size = 12"
7/12=.58 (answer times 100 = 58%)

Here's a little tip from the Northwest Quilters, Inc. Newsletter:

How to make a 9-patch block from an 8 inch square.
Use a carpenter's "trick." Draw an 8 inch square on a piece of paper. Then lay a ruler diagonally from side to side placing the beginning edge (or zero mark) on one of the parallel side lines and the nine inch mark on the opposite parallel side line. Mark a dot at three inches and a dot at six inches. Move the ruler up or down and mark the same way. Use the ruler to draw a line thru these dots from top to bottom of the square. Turn the drawn square and do the same marking the other way to make the nine equal squares needed for a 9-patch. You can use this method to mark an odd number of equal divisions of anything.
