There are a few things you need to know in order to calculate how much fabric you need for curtains. First, you need to determine the size of the window. Second, you need to decide how long you want the curtains to be. Third, you need to decide how full you want the curtains to be. And fourth, you need to know the width of the fabric. Once you have all of that information, you can use this formula to calculate the amount of fabric you need: (width of window + 2) x (length of curtains + 2) x (fullness of curtains) / (width of fabric).

**Summary**Close

To calculate how much fabric you need for curtains, measure the width and height of the window and multiply those numbers. Then, add several inches to account for hems and seams.

## How do I calculate how many curtains I need?

If you want to hang curtains in your home, you’ll first need to measure the width of your window. Once you have that measurement, you can divide it by the width of a single curtain panel to determine how many panels you’ll need. If you want a full, luxurious look, you can multiply the width of your window by 25 to 3 to get the number of panels you’ll need for a tightly gathered look.

In order to find the amount of fabric you need to make two 48″ high curtains, you need to take the final height and multiply it by the number of panels needed. In this case, that would be 2. So, you would need 96″ of fabric. However, you can’t just buy one yard of fabric, because a yard is only 36″ long. Therefore, you would need to buy at least 3 yards of fabric, which would give you an extra 12″ of fabric to work with.

### What size curtains do I need for 120 inch wide window

For a 120 inch window, you need curtains with a finished width at least 15 times that, but better are those with twice that width and even three times the width for sheers. Therefore, for a 120 inch window, you need two panels of 120 inches each for twice the width and a luxurious gather.

If you want your curtains to have a certain look, it is important to take the time to measure the width of your window. The total width should be no less than 15 the width of your window. For example: If your window measures 48″, add 12″ to equal 60″. If you want to have two panels, divide this amount by two which will equal 30″, meaning the curtain size for each panel should have a minimum width of 30″.

## How many yards is a standard curtain?

If you are looking for a yardage chart for a standard window PAIR of basic drapery panels @ 25x fullness, the following table should be of help. It lists the finished length up to 60″, 70″, 80″ and 90″ long and the corresponding yardage required for solids & small prints and medium prints (v-repeat up to 12″).

Finished Length Up To:

As always, it is best to consult with a professional before starting any project to ensure you have the correct supplies.

When measuring for curtains, it is important to measure from the bottom of the rod pocket seam to the bottom of the curtain. This will ensure that the curtains are the correct length and will hang properly.

## How many yards of fabric do I need for a valance curtain?

If you’re looking to make a self-lined gathered valance, you’ll need to take into account the width of the fabric you’re using. To do this, simply divide the cut fabric width by the width of the chosen fabric. This will give you the number of widths required. From there, multiply that number by the cut fabric length. Finally, divide the result by 36 to get the number of yards of fabric required.

When measuring for curtains, be sure to account for the width of the window frame, as well as the desired amount of coverage on each side. A good rule of thumb is to add 8-10 inches on each side, for a total of 16-20 inches added to the window width. This will ensure that the curtains will have adequate coverage and fullness.

### What size curtains do I need for a 100 inch window

If you want your curtains to hang off the window when they’re in the open position, you should make them about 25% wider than the window itself. So, if your window is 100 inches wide, you should make your curtains 125 inches wide.

If you have single-hung windows, then you need only one curtain per window unless there are multiple rooms in which you want light coming in through them (such as an office or a bedroom). If you have a high-ceilinged room with lots of windows, then yes, you probably do need two curtains.

## What size curtains do I need for a 72 inch wide window?

If you want your curtains to look full and properly cover your window, a common rule is to get curtains that are at least 2 times the width of your window. For example, if your window is 36″ wide, you’ll need curtains that are at least 72″ wide.

If you want your curtains to hang properly, you should follow the general rule and hang them two-thirds of the way up the space above the window. However, we recommend that youhang most curtains at least 4-6 inches above the window frame to ensure they look good and function properly.

### What length curtains make a room look bigger

For the best results, install the curtain rods high above the windows and keep the rods’ length wider than the windows. Add 3 inches beyond the window frame on each side to:

-Make your windows look larger than they are

-Open the curtains completely to allow maximum light penetration

When choosing curtains, it is generally best to choose ones that are longer rather than shorter. Standard curtains come in three lengths—84 inches, 96 inches, or 108 inches—but experts say you should opt for the longer lengths if possible. This is because longer curtains can give a room a taller and more elegant look, while shorter curtains can make a room look more juvenile.

## What is the average curtain length and width?

There is no rule for how long your curtains should be, but the standard curtain lengths are 63, 84, 96, 108 and 120 inches long. Curtain panels are typically 48 inches wide. Curtain lengths will also vary depending on the style you’re looking for. For example, “float” curtains only go down to the windowsill, while other styles may reach the floor.

The width of your curtains should be 2-2.5 times the width of your window. Exceptions to this rule are if you’re hanging curtains just to frame a window and don’t intend to actually use them, in which case you can round down to 1.5 times the width of the window.

## Conclusion

To calculate how much fabric you need for curtains, you will first need to measure the width and height of your window. Once you have these measurements, you will need to add an additional two inches to the width and height. This will allow for seams and hems. To determine how much fabric you will need, you will need to multiply the width by the height. This will give you the number of square inches that you will need to cover. Finally, you will need to divide this number by 36. This will give you the number of yards of fabric that you will need to purchase.

If you’re planning on making your own curtains, you’ll first need to know how much fabric to buy. To calculate this, you’ll need to know the dimensions of your window, the width of your fabric, and the style of your curtains. Once you have that information, you can use this formula: (window width + curtain fullness) x 2 = amount of fabric needed. For example, if your window is 2 feet wide and you’re using 45-inch-wide fabric, you’ll need 4.5 yards of fabric.
