Paper comes in differing sized sheets or may be sold in big roles that only machines can lift.
There are also differing qualities of paper as discussed in the related link below.
Your question is therefore too simplistic for the provision of a simple answer.
The weight of a ream of paper depends on the kind of paper. A ream is 500 sheets. The weight for 500 sheets of 24 lb., 11 inch x 17 inch book paper would be 4.72 pounds. A ream of 20 lb. 8.5 inch by 11 inch letter-size paper weights 5.00 pounds.
A standard sheet of printer paper, typically 20 lb (pound) bond paper, weighs about 4.5 grams (0.16 ounces) per sheet. This weight can vary slightly depending on the type and thickness of the paper. In general, a ream of 500 sheets weighs approximately 5 pounds.
