When you're wondering which one to print, remember, an 18 inch is the size of an American Girl doll or and our generation doll. A 12 inch is a barbie, monster high, la dee da, etc. a Mini doll size is for a littlest pet shop or my little pony figure. Also, when printing, eyeball it on the page before printing it out. Make sure it is not being cut off, i unchecked the "fit picture to page" button. Also, i clicked the 4×6 button. But really, feel free to check it yourself and make changes to my design.
