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 "grams per square meter" measurement. A more "worldwide" unit of measure, GSM is an easy way to quickly compare the weight (density) of papers.

Please note that 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.
