Paper weight is the general thickness of a paper. The greater the paper weight, the heavier, thicker, and sturdier the paper is. Papers with more bulk hold up well when there is heavy ink coverage. For full color photos from your desktop, thicker inkjet photo papers are best. However, some desktop printers may not handle thicker papers well, especially if the printer doesn't have a straight paper path.
