Most of my binders hold 38 pages. These are all 12 x 12 card stock pages decorated with pictures, stickers, or other embellishments that are raised slightly off the page. Lately, I have been using insert sheets where you slide extra photo's of the event into the slots. I place these in between the decorated pages. Since these are thinner, my binders hold around 44 pages, depending on how many insert sheets I use.
