How to choose curtain lengths

Curtains help control light, give you privacy and increase energy efficiency – not to mention what they do for the style of the room. However, choosing the right length when you hang curtains can be a bit confusing. Here are some tried and tested ways to get the look you’re after.

Floor length is a clear favourite

One of the most common choices is floor-length curtains – always elegant, always easy to maintain and convenient when hoovering. Just make sure they go all the way down to the floor as high-water curtains just don’t look right.

Other styles of curtain lengths

Sill length curtains are popular if you’re placing furniture like a desk or sofa right below the window. A pro tip is to add a few centimetres to your width measurements to give the appearance of a bigger window. Puddled curtains bring texture and character to the room. A softer fabric helps them flow nicely onto the floor.

How to measure and plan your curtain solution

Step 1: Consider the length of your curtain

Do you prefer window sill length, apron length, floor length or do you want your curtains to softly pool on the floor?

Step 2: Decide on ceiling-mounted or wall-mounted.

Take a good look at your window, its opening and if there is a window sill, radiator, plants or furniture placement to take into account.

  • Choose whether you wish to hang curtain rods directly from the ceiling or on the wall. This will determine the curtain length.
  • Ceiling-mounted offers better sound absorption, isulation and make the room appear larger.
  • Wall-mounted solutions are usually placed about 15 cm above the window. But it is really up to you decide the height.

Plan a distance of about 12-15 cm between the curtain and the window/wall, so it does not obstruct the window when pulled to the side.

Step 3: Calculate the width of your curtain rod or rail.

Measure the width of the window. For fabric curtains, add at least 15 cm on each side so they cover the entire window, and allow the curtains to open fully. Tip: Are you combining curtains with roller blinds? Add a few centimeters to the width, so the curtains are wider than the blinds.

Step 4: Calculate the number of brackets.

Rules for a stable rod or rail:

  • Use 2 brackets for curtain rods or rails up to 140 cm.
  • Use 3 brackets for curtain rods or rails between 140 and 280 cm.
  • Use 4 brackets for curtain rods or tracks longer than 280 cm.
