If you are thinking of how big is 8x10, keep in mind that 8x10 is the same size photograph whether it is put on display horizontally or vertically. Vertical shots are good for single headshots, while horizontal shots might be better for landscape photos, group photos, or wider shot, according to Visuals Clipping. It should be dependent upon the original image in question, and how the subjects of it are positioned. Taking pictures of the crop before printing can help prevent the important part of the photograph being cropped.
