Enlarging & Reducing Photocopy Chart

I am working on a quilting design for my latest quilt. I drew the design just the way I wanted it. But wouldn't you know that it was too small. Here is the chart I use to make it just the right size!

	1”	2”	3”	4”	5”	6”	7”	8”	9”
1”	100%	200%	300%	400%	500%	600%	700%	800%	900%
2”	50%	100%	150%	200%	250%	300%	350%	400%	450%
3”	33%	66%	100%	133%	166%	200%	233%	266%	300%
4”	25%	50%	75%	100%	125%	150%	175%	200%	250%
5”	20%	40%	60%	80%	100%	120%	140%	160%	180%
6”	17%	33%	50%	67%	83%	100%	117%	133%	150%
7”	14%	28%	43%	52%	71%	86%	100%	114%	128%
8”	12%	25%	37%	50%	62%	75%	87%	100%	112%
9”	11%	22%	33%	443%	55%	66%	77%	88%	100%

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.

Example
To enlarge from 5" to 7", from the left column find 5", look across to 7". The percentage is 140% .
To reduce from 6" to 5", from the left column find 6" and across to 5". The percentage is 85%.
