Measure the Window
Sewing your own curtains allows you to have exactly what you want on your windows. Your first step to calculate how much fabric you will need to buy to sew your own curtains is to measure the window.

Calculate the Length of Each Panel
Use this formula to calculate the amount of fabric you need if the fabric is wide enough to create each panel.
______ Finished Length______ Plus the header (facing) to the bottom of the rod__+ 1"_ Plus 1" in order to turn under 1/2" at each end of the panel______ Plus Hem (allow 2" to 3" depending on the weight of the fabric you are using. A light weight fabric is usually better with a 3" hem to "weight" the hem and help it hang properly.______ Equal total... length needed for each panel______ Times the number of panels______ Divided by 36" (for a yard of fabric or 39.37" for a meter of fabric}______ Add-on for tie backs, ruffles, fabric shrinkage, extra width and other trimming desires or matching pattern repeats in print fabric.Continue to 3 of 5 below.

Calculate the Width
Many windows will need more fullness than one length of fabric will achieve. A simple rule of thumb is that a curtain is one and a half to two times the width of the area it is meant to cover. A heavier fabric will provide fullness that a lightweight fabric will not supply. The lighter the weight of the fabric the more fullness it will require.For appearance and proper hanging, it is best to have at least a half width of the original fabric when you need to add width to a panel. If you only want... a couple of inches more than the original length of fabric will offer, cut away from the first length of fabric and add it on with the second length seamed to the first length of fabric.
Add additional panel lengths to achieve the desired width to the original length of the panels to purchase the proper amount of fabric. A one-inch hem is usually sufficient for the sides of curtains.Continue to 4 of 5 below.

Before You Buy and Tips
Before You Make Your Final Purchase
- Will the fabric shrink? Always preshrink the fabric before you cut it.
- Did you double check your calculations? Always measure twice to be positive before you cut!
- Is there a print on the fabric that will need to line up on the panels? Have you allowed for this?
- Do all the windows receive the same amount of sun or is one set of panels apt to fade more than the others? It may be worthwhile to buy enough fabric for an extra set of panels while you can get the fabric.
- D...o you want any extra fabric to sew or trim pillows?
Tips and Solutions to Fabric Shortages
Continue to 5 of 5 below.
- Use a different fabric for hems and topper facings, seaming the fabric that will be on the back of the curtain at the folds. Using under-stitching helps the additional fabric stay to the backside of the curtain.
- Add borders of a contrasting print or solid fabric to add length and/or width.
- Use drapery weights to assist the way a curtain hangs.

The selvage of many print fabrics has pattern repeat markings. These markings allow you to know when the pattern starts so that you can easily have every panel be the same.The amount of extra fabric to buy will depend on how often the fabric repeats. There is no getting around buying extra to match a print.
