Hi Cassie
Here is a chart I found about enlarging/shrinking blocks. Sorry, I don't remember the site. I hope this will help you.

Okay you have a block that is 5" but you would like it to be 12” or do you have a block that is 15" and you would like it to be 6" well here is how I have worked it out :)
Example 1: Current size = 5" and you want a 12" block 12/5 = 2.4 now take the 2.4*100= 240%
Example 2: Current size =15" and you want a 6" block 6/15= .4 now take the .4*100=40%
/ = Dividing * = multiplying
I have created a table 15x15 for fast check on % to be photocopied by. As you can see there are some blank squares :) well dividing and then multiplying with it's self it will always come back as 100% so I have left them blank :)
