I just published my first book, research into the USAAF in my local village during WW2 - printed in A5 paper size This was suggested by my publisher as it was the most economcal size to print to keep my costs down The book received excellent reviews but it was suggested that any reprint should increase the book size slightly. As it happens I am already working on ver 2 7 x 9inch possibly What would be the next standard size above A5 ? Looking online it appears that anything goes, but would my print costs rise if there was an excessive waste of paper due to trimming Look forward to amy advice received
