By default the 3500 and 300 Hingeless series album are made with Standard Pages.

As the albums start getting past a certain side count we suggest that you consider Thin Pages just so that the book is less heavy and not bulky.

For a Larger Size Album such as a 12×12 or 11×14 can easily go to 80 sides with Standard Pages. Though heavy it will not look bulky. Past 80 sides you may want to consider Thin Pages.

For a Medium Size Album such as a 10×10 or 8×10 can easily go to 66 or even 70 sides with Standard Pages. It will not look too bulky. Past 70 sides you may want to consider Thin Pages.

For a Smaller Size Album such as an 8×8 or 6×8 can easily go to 50 sides with Standard Pages. It will not look too bulky. Past 50 sides you may want to consider Thin Pages.
