Question: I am trying to get the layout for a KDP Amazon paperback book. I have done 8x8, 8.25X8.25 and even 8.5x8.5 and I can't seem to line my page upright. In Affinity after you set your page, it comes with little boxes on the page and as long as you should stay in the box you should be good. Is that correct? because I have kept in the lines and it looks like it has too much white border or it will go out the lines. It is a 2400px squared and 129 pages. I have also have used the magnet to snap to guide to help me. The first picture is in Affinity the 2nd is the results in Amazon. (PS I am still 2 weeks new so don't get too technical.
