GSM - Grams per Square Meter - This is the general measurement of paper weight and this does actually relate to the weight of the paper and this is the simplest and most effective way of describing the weight of paper.

Generally PAPER WEIGHT does not refer to the actual weight of a stock, but instead refers to the thickness and sturdiness of  

The stock chosen to print on sevierly effects the print finish, design decisions should be made about the stock weight, finish, grain, coat, cost and quality at an early stage in the design process.
