Georgia-Pacific, HP and Hammermill all offer inexpensive copy paper choices. These are typically marketed as Standard or Everyday copy paper options. Office supply stores sell their own store brands of copy paper as well.
The weight and brightness, or whiteness, of copy paper are the primary factors that determine copy paper price. Thicker, whiter paper is more expensive than thinner, less brilliantly white paper. Paper is packaged according to ream weight, which is calculated by the weight of the paper itself. Twenty-pound weight paper, the most common type of copy paper, typically is packaged in 500-sheet reams, while a ream of heavier paper (e.g., 22-pound weight) contains only 400 sheets.
