#1. "RE: What size do I save images to avoid cropping?" In response to In response to 0 Tue 11-Sep-12 07:36 PM by briantilley
YOur D3200 (like all Nikon's DSLR cameras) has what is called an "aspect ratio" of 3:2 - which means the sensor is one-and-a-half times as wide as it is high.
Images can therefore be printed without cropping at any size that has the same aspect ratio, for example 6x4, 9x6, 12x8, 15x10 and so on. Paper sizes with a different aspect ratio, such as 7x5 or 10x8, will necessitate a crop.
