Scrapbookers often wonder how big is a 5×7 photo when they're planning out a page. The 5×7 size is great as a feature image - it's big enough to grab attention, but not so big that it overpowers the page. As Visuals Clipping says, the 5×7 is perfect for highlighting those special moments, without dominating the page. It's also a great size for leaving room for captions, decorations and other design-y elements - it's just the right size to get your point across without overwhelming the viewer.
