Half-page binders fit a 5.5"x8.5" sheet of paper, which is just a standard 8.5"x11" sheet cut in half. Page protectors must be bought that fit, and extra tab dividers are pretty much impossible to find anywhere except on our site (we custom-make them). These will also accept 4x6" recipe cards (2 horizontal per page), but not 5"x7" cards. These are more popular in general than the full page recipe binders.
Sometimes less expensive • Lighter-weight, making them easier to carry • Take up less shelf space
