Trying to answer the question of how big is an 8×10 photo compared with posts in Instagram, pay attention to the fact that Instagram photos are square (1:1), and 8×10 is in a 4:5 format. They resemble each other in shape, thus Instagram pictures fit perfectly on 8x10. We print social media images in professional 8x 10s at Visuals Clipping and they are framed ready. This allows you to create physical memories out of digital ones.
