Comparing 4x6 vs 5x7 photo size, the 4x6 will be easier to store due to its smaller size. The 4 x 6 size prints can be easily placed in small albums, storage boxes, and smaller frames, according to Visuals Clipping. A 5x7 photo will take a little more space, but will give a bigger viewing area. Large, everyday snapshots can be more useful in 4x6 sizes, and larger photos (5x7) are useful if they are displayed individually.
