Here is a sample of how I design a wedding album. Technically, you can get about 60 images into a 40 page album. That is 20 sides and 40 pages. If you put one large and 4 small, then you can get 20 x 5, however, some pages (the ones with the special shots), you want to take up the entire spread with; or at least one page. So, I always ask for 60, sometimes need more and sometimes use less.
