No, the final book will not be undersized.

The finished size will be the size you order at either 12" x 9" or 9" x 9".

Family Memories respects your original design, our software and production work flow are designed to have full bleed on every page, so your book will be bound at the exact finished size, either 12" x 9" or 9" x 9".

This is just another reason why Family Memories stands out in the market while you may get the undersized books from some other publishers.
