Calculating by Square Yard

Another common method of determining fabric weight is by calculating by square yard. This method is useful when you know the area of your fabric but don’t have access to a fabric scale.

The fabric weight formula is:

Fabric weight (in ounces) = (length of fabric in yards) x (width of fabric in yards) x (weight of fabric per square yard)

For example, if you have a fabric that is 3 yards long, 2 yards wide, and weighs 8 ounces per square yard, the weight would be:

Weight = 3 x 2 x 8 = 48 ounces

So the fabric weight would be 48 ounces.

Using a Fabric Weight Calculator

A fabric weight calculator is a convenient way to determine the weight of your fabric without having to do any calculations yourself. Simply input the fabric dimensions and weight per square yard, and the calculator will do the rest.

There are many online fabric weight calculators available, but be sure to use a reliable one. Some calculators may provide inaccurate results if they don’t take into account the density of the fabric.

Now that you know how to determine the weight of your fabric, let’s take a closer look at the different types of fabric weights and their common uses.

Using a Fabric Scale

If you have access to a fabric scale, using it to calculate fabric weight is a simple and accurate calculation method. Fabric scales are widely available in sewing and crafting stores. Here’s how to use it:

  1. Place your fabric sample on the scale and record the weight in grams. Make sure to remove any excess fabric or debris that may affect the accuracy of the reading.
  2. Measure the dimensions of the fabric sample in inches. To determine the fabric weight per square yard, multiply the weight in grams by 0.0566 and divide the result by the square footage of your fabric sample.

For example, if your fabric sample weighs 200 grams and measures 18″ x 18″, the fabric weight per square yard would be:

(200 grams x 0.0566) ÷ (18″ x 18″ ÷ 1296) = 6.27 oz/sq yd

It’s important to note that fabric scales may not be as accurate as other methods when measuring lightweight or sheer fabrics. In these cases, it’s recommended to use an alternative fabric weight calculation method such as calculating by square yard or using a fabric weight calculator.

Calculating by Square Yard

If you prefer a math-based approach, you can calculate the fabric weight by using the fabric weight formula. This method will require you to measure the length and width of your fabric in yards and use a simple formula to determine the fabric weight per square yard.

To calculate fabric weight using the fabric weight formula, follow these steps:

  1. Weigh a piece of fabric that measures exactly one yard in length and width. Record the weight in ounces.
  2. Multiply the weight in ounces by 16 to convert it to grams.
  3. Divide the weight in grams by the area of one square yard (which is 1,296 square inches). This will give you the fabric weight per square yard in grams.

The formula to calculate fabric weight is:

(Weight in ounces x 16) ÷ 1,296 = Fabric weight per square yard in ounces

For example, if a one-yard piece of fabric weighs 8 ounces, the calculation would be:

(8 x 16) ÷ 1,296 = 0.0987 ounces per square inch

This means that the fabric weight is approximately 0.1 ounces per square inch.

Calculating fabric weight by square yard is an accurate and reliable method that allows you to compare the weight of different fabrics easily. However, it does require a bit of math and measuring, so it may not be the most convenient method for everyone.
