Greetings Melissa!

To best feature your creations you want to make your book 8.75x8.75 with a 1/4 inch margin. Thanks for your question!

I am in the process of creating a digital scrapbook and I want to make sure I do the margins correctly. I am planning to purchase an 8.5x8.5 size. Do I need to make the page size the same dimensions and then have an indented margin of 1/4 inch, or do I make the size 8.75x8.75 with a 1/4 inch margin? My files will be in png format, not pdf when finished. Thanks you
