These equivalencies apply to common copy or “bond” paper. Those sheets are 4x the size of an 8.5″ x 11″ paper, hence the 20 pound weight. So what’s up?Ī 20 pound paper weighs 5 pounds, because the 20 pound measurement uses uncut sheets of paper, which are 17″ x 22″ sheets. A practical way to show the results for comparison is to create a conversion GSM BASIS WEIGHT The GSM (grams per square meter) tells paper. pounds) paper can still be compared using ‘equivalentweights’.The various measures can easily be synchronized by using a conversion formula. 300 gms paper will be the same thickness no mater if it is in a notebook or an ‘Emperor’ sheet at 40×60 inch. techniques used to measure paper weight, (metric vs. 500 sheets of 22×30 at 300 gsm, and yes this is mixing metric with imperial measurements, weights 140lb. The following table shows equivalent weights for different grades of paper. That’s because metric countries - mainly Europe - measure by the square meter while the US measures in pounds per ream (500 sheets).īut we all know that 500 sheets of 8.5 x 11 paper doesn’t weigh 20 pounds. 300 lb (638 gsm) vbuben: These weights in pounds only apply to a ream of Imperial size paper, 22×30 inches. To convert grammage (G) to mass in pounds (BW) of custom trade sizes for.

There is more to it though, as if paper weighs 75 grams per square meter, it clearly doesn’t weigh 20 pounds per square foot. properly mass per unit area) of paper has been basis weight, ream weight. Enter the basis weight, number of sheets, and the sheet size. For reference 20 pound and 75 gsm paper are of equivalent thickness. When talking in grams, as in “75 gsm paper” you’ almost always note that the measurement is based on a square meter. Paper weight can be measured in pounds, as in “This is 20 pound paper” where you’d typically leave off the dimensions associated with the weight.

A typical weight for copier paper is 24 pounds.These system is usually known as the “paper weight” but that’s often confused with a “paperweight,” as in the thing that stops papers on your desk from blowing away when a fan is on, so you also hear the term “grammage” to describe what we are talking about here. Check both data points when deciding on an inkjet paper to purchase. While weight and thickness are related, you should not use the weight to assume thickness. If we do not know lbs nor gsm when buying a paper, we can roughly determine its thickness by measuring with a digital caliper, only slightly touching the paper´s edge. Pounds to GSM Paper Weight Conversion Use the chart below to compare inkjet paper weight in pounds to the metric GSM (grams per square meter) measurement. Thus, when knowing gsm the paper weight in lbs is about 0,59 times the gsm-value. Basis weight describes the weight in pounds of a ream of 500 sheets. The paper weight in gsm turns out to be approx. This metric is most commonly applied to cut sheet paper used in a typical office environment, like copier paper. Pounds: Lastly, there’s basis weight, which is described in terms of pounds. Note: mil should not be confused with millimeters (mm). A photo paper and a fine art paper might both be 250 gsm, but a fine art paper is often less dense and might have a mil rating of 15 vs 10 for the photo paper.

While there is a correlation between gsm and mil (more gsm usually means more mil), it is not an exact correlation. Conversion Type: GSM to US Basis Weight Grams/Square.

Mils: The second metric is mil, which is a measure of thickness. Use our paper calculator to convert various paper elements, calculate specific weights, prices and more. To reverse the calculation simply select 'gsm 2->lbs' and enter a gsm value. The higher the gsm, the heavier the paper. Environmental Paper Assessment Tools To use the Weight Conversion tool, please select a Type of Paper from the pull down menu, then enter a value in pounds and hit calculate. A typical gsm for a good quality photo or proofing paper is 250. GSM: The first is Grams per Square Meter (gsm), which measures mass per unit of area. A: There are three most commonly used metrics for describing paper weight or thickness – gsm, mil, and pounds.
