How to determine width of curtains

Whether you are planning on making curtains yourself, buying them from a shop or ordering custom curtains online, there is one piece of information that will be vital to your purchase. This is the measurement of your window. Determining the width of curtains can be a tricky proposition. Though it may seem like common sense to simply measure the window and use this width, determining the correct width for curtains requires a few more steps.

Skill level:

Things you need

  • Measuring tape
  • Paper
  • Pencil or pen

  1. 1

    Measure the width of your window at the top. Begin at the outer edge of one corner and extend your measuring tape to the opposite outer edge. If the window has trim, measure to the edge of the trim.

  2. 2

    Add 7.5 cm (3 inches) for each side of the window to estimate the placement of rod brackets. This will equal a total of an additional 15 cm (6 inches) on top of your first measurement.

  3. 3

    Double the final measurement acquired in Step 2. For full curtains, you should make sure that the fabric is at least twice the width of the window measurement. A curtain that is the same width as the window will not be able to hang in folds.

  4. 4

    Record all of your measurements on a piece of paper to keep with you when shopping for curtains or material for homemade curtains. Make sure that all of your measurements are made in either inches or centimetres. Do not mix the two.

Tips and warnings

  • If you are buying two curtain panels separately, keep in mind that their combined measurement should equal your final window measurement. Do not buy two panels that are each twice the width of the window as this will result in far too much fabric.
