Make My Book - User Guide
You can choose a standard page size listed, or you can click on "customize page size" and a box will open below for you to fill in a custom size. It's fine to just choose what's closest as we will bind according to size sent. This is just to give a general idea of what your book will look like and cost.
After page size is chosen, select from preset spine thicknesses or add your own if you prefer to measure the exact width. This will allow the software to calculate how the words will fit on your spine.
Once choices are made, click NEXT to go to next section.
