If you only have a handful of photos you want to store and display, the number of pages in your album might not be a big concern. In fact, you’ll want an album with less storage space, so you don’t end up with a half-full album. But if you have a lot of photos, you’ll likely need a large album, and maybe even more than one. The size of your photos is also important. The most common photo sizes are 3x5, 4x6, 5x7 and 8x10 inches. If you have photos in many different sizes, you’ll need an album that has frames for both your vertical and your horizontal ones.
