I recently changed all my prints from size 5×8″ to 5×7″. Why? 5×7″ is the standard and somehow, a long time ago I decided to do 5×8″ lol. The pictures turned out a little too wide as you can imagine. It wasn’t until I realized an order came in for that size (most popular print sizes are 8×10″ and 11×14″) that I noticed it printed pictures that were wider than normal.
