Inkjet Paper Pounds to GSM Paper Weight Conversion Chart

Paper size reference metric to US chart


Use the chart below to compare inkjet paper weight in pounds to the metric GSM (grams per square meter) measurement. A more "worldwide" unit of measure, GSM is an easy way to quickly compare the weight (density) of papers.

While weight and thickness are related, you should not use the weight to assume thickness. Check both data points when deciding on an inkjet paper to purchase.

BOND WEIGHT - The basis used by Red River Paper to describe our products. It is defined as the weight of 500 sheets of 17x22.

COVER WEIGHT - A basis used often in graphic arts. It is defined as the weight of 500 sheets of 20x26.

METRIC WEIGHT - A basis used around the world. It is a superior scale because it uses a single standard. The weight of a square meter of paper.
