How to calculate various amounts of fabric yardage?

Answer 1

Width Measurement * Separately measure the width (in inches) of each wall you're planning to cover, unless you'll be working around an outside corner; in that case you'll use one fabric cover, starting it at one wall edge, wrapping it around the corner, and continuing to the far edge of the wall. * To find the number of fabric panels required for one wall, divide the width of the wall by the usable width of the fabric, taking into account the amount of fabric taken up in seams (plan 1/2-inch seam allowances). If you are using sheets, use the width of the sheet. If your calculations result in a fraction, add a whole panel. This extra fabric width will give you some leeway to match the pattern at corners.

Height Measurement * Measure the height (in inches) of the same wall from the ceiling line (or lower edge of the ceiling molding) to the top of the baseboard. Take this measurement in several places to check for variations; use the largest figure. Before choosing sheets, be sure your wall is no higher than the length of the sheet. * Add 6 inches to the height measurement as insurance against errors. If the fabric has a pattern repeat, add the repeat length to the height measurement to allow for matching the pattern at the seams. Your final figure is the working height of the wall. Total Fabric Yardage * Multiply the working height figure by the number of fabric panels needed for the wall; divide this figure by 36 to convert to the number of yards of fabric required for the wall you've measured. * Repeat the calculations for each wall you're covering. Add together the yardage for all the walls to determine total required. Add extra yardage if you plan to finish the walls with double welt (instructions for measuring for trim follow). if i have a 54" wide farbric and the chair i want calls for 2 linerar yards but the fabric has a 10% repeat how do i calculate how much total bafric i need?

Answer 2

Fabric yield all depends on what you are going to cut out the fabric.

The easiest way to figure out your fabric yield is by the following calculation :

( number of metres used ) divided by ( number of garments cut)

for example:

10 metres / 10 shirts = 1 metre per shirt

So your fabric yield is 1 metre per shirt

Is is not out of the question to have yields such as 0.17 metre yield per garment , it all depends on what is cut and how it is cut.

Answer 3

The way that a fabric gsm (grams per square meter) would be calculated would be for a person/manufacturer, to make a swatch, one meter square, and then weigh it. Then they would know the grams per square meter.

Each type of fabric would have a different weight. For example, a heavy corduroy would weigh more than a silk fabric of the same size.

Answer 4

In the United States, the weight of fabric is calculated in ounces per square yard squared. In other countries, it is calculated in grams per meter squared.

Answer 5

120x100 80/2x80/2

Answer 6

most places measure it out in yards
