Calculating the weight of fabric is important for both the at-home craft enthusiast and the professional fashion or interior designer. Clearly understanding the weight of a fabric will dictate the drape of the fabric on a person, in a window or in a wide variety of other applications. If the weight is miscalculated, some major errors in costs, feel and look can manifest, creating work that is not salvageable.
Measure the yardage of the fabric. One yard equals 0.9144 meters, therefore one yard squared equals 0.9144 meters times 0.9144 meters, and equals 0.83612736 meters squared. Fabric weight calculations are generally measured grams per square meter.
Use grams as your main calculation for weight, when weighing fabric. The total of 28.3495231 grams by 0.83612736 meters squared will equal 33.90574744 grams per meter squared. This is the most common equation used in the fabric industry.
Round up to three decimal places from 33.90574744 to get 33.906 grams per meter squared. Print off general calculations from Designer-Entrepreneurs.com, and keep them handy to avoid difficult math calculations. Always use the easiest, and most common measurement of grams per meter squared.
