Enlarging/Reducing Scale for Patterns
 
 
To use this table:
Locate your current block size down the left hand column and then across the top find the size that you want your new block to be. Follow the column down and the row across till they meet and this will give you the amount you either need to enlarge or reduce your original pattern.

To be able to enlarge or reduce to anysize that is wanted (if it isn't in the above table) use the basic formula here:
(block size wanted) / (current block size) = (percentage to enlarge or reduce original block)*100

Example 1:
Current size = 4" and you want a 12" block -
12/4=3 -> 3*100= 300%

Example 2:
Current size =12" and you want a 7" block -
7/12=.583 ->.583*100=58% or 59%
