I am new to Lulu, but it was recommended to me by a friend who said that they loved it. Basically, my friend and I both wrote a murder mystery as a gift to someone else. We wrote it in Google Docs so that we could both write at the same time and see what the other person is writing, and I put it into Word once we finished. I've completely finished formatting it now, but I've found a (possible) problem. Basically, the size of paper we want to use is 6" x 9". Since we created it in Google Docs, I just picked the closest thing for the page size (6.93" x 9.84") because it was the "B5" paper setting and I assumed that's what Lulu's size was since I hadn't looked at the page in a while. Now, I've formatted the whole book using a 6.93" x 9.84" page size, and Lulu's page size is 6" x 9". If I try to reformat it using 6" x 9", I am probably going to have to start from scratch because I tried it earlier and it ruins how all pictures and headers are lined up. I'm just wondering if giving Lulu a file with a 6.93" x 9.84" paper size instead of 6" x 9" will affect the book and have some of it chopped off of the edge. I set the margins correctly and everything, all following the video "How to Format Your File (PC)."
Basically, will 6.93" x 9.84" sized paper work for the 6" x 9" book size?
