Which Photo Size is Best? (4×6 vs 5×7)

The standard aspect ratio 3:2, common in modern digital cameras, is embodied by the photo size 4×6. This eliminates the need for scaling or cropping in most cases. However, if you want a 5×7 inch print, you will need to adjust the dimensions in the photo editor.

Because of their smaller size, 4×6 prints tend to be more cost-effective, whether you make them at home or through an online service. Enlarging an image for a 5×7 inch print, especially if you follow the rule of thirds, will require cropping and possibly changing the original composition.

While 5×7″ prints may have a greater visual impact due to their larger dimensions, the choice between 4×6 and 5×7 ultimately depends on where you intend to display the photo. For albums, 4×6 is typically recommended, optimizing space for multiple photos.

In essence, the preference between 4×6 and 5×7 prints is subjective. There is no definitive right or wrong choice; it’s about selecting the size that best suits your specific needs.
