Measuring for curtains is a simple task, but only if you know how. Our step by step guide will show you how to get all the appropriate measurements correctly. We have also included tips, advice and things to consider when you measure for curtains. Measuring for curtains can be confusing if you've never done it before. However, all you need is a measuring tape and a calculator to figure out the right curtain length and width. Figure out some basic measurements as a starting point and then add or subtract depending on your specific needs. When you're done, you can custom order the right curtains for your windows. Leaving your windows naked and bare means you’re missing out on a big interior design opportunity. Beautiful window treatments provide privacy, filter sunlight, and add warmth while bringing style to your home. Before you can choose the perfect drapes for your space, it’s vital to get the correct window and curtain measurements.

CURTAIN POLE & CURTAIN TRACK?
The pole / track should extend approx. 15-30cm past either side of the window and approx. 12-15cm above the top of the window. This will help minimise the light when curtains are closed and also allow for curtains to be gathered either side of the window when open.
First we need to measure the inside width of the window recess. (Measure A)
Next, decide how far your curtains will over-hang the wall, each side of the window. This would normally be around 20cm (8 inches) each side and enables the curtains to open wider, allowing more daylight to enter the room. (Measure B)

 

DETERMINE ROD LENTH

Before you measure your window for width, it’s best to choose the length of your curtain rod. Curtain rods are typically extended 3 to 6 inches past a window frame. However, because rods can be installed either inside, below, or above trim mount, determining where you install your rod affects the length.

Inside Trim Mount
For streamlined, tailored window treatments, suspend curtains from within the window frame. Opt for curtain rods with protective end caps and an expandable design for a snug fit. Window treatments for this modern style should only be about as wide as the interior of the window or slightly wider if you want a gathered look.

Below Trim Mount
If the top of your window frame has beautiful molding, consider mounting your curtain rod just below the trim. This is a great way to showcase the craftsmanship of your molding while adding privacy and style to your windows. Look for a rod that reaches at least 3 to 5 inches beyond the width of the window on either side for a full look.

Above Trim Mount
The ideal placement for a window rod is typically about 6-12 inches above your window frame. However, it really depends on the available space between the top of your window and the ceiling, and the overall aesthetic you’re going for. Curtains can be hung as high as 20 inches above the window frame to create an elongated appearance. The higher and wider your curtain rod is placed, the larger your window will appear.

 

MEASURE YOUR CURTAIN WIDTH
When you measure for curtains width, it is important to consider the ‘gather’. To have curtains with a medium gather when closed, we take our track/pole measurement (C), multiply it by 1.5 then divide by The result is the required width of Each curtain. For curtains with full/normal gather when closed, measurement C would be the required width of Each curtain.
If you desire a heavy gather, multiply measurement C by 2.5 then divide by 2. Again, the result is the required width of Each curtain.

 

CHOOSE YOUR CURTAIN LENGTH
Next, you’ll want to consider the interior design style you hope to achieve, which will determine the right length for your curtains. There are three ways to hang your curtains, depending on what look you prefer.

Above Sill
Curtains that hang above the sill typically sit 1 cm above the windowsill.

Below Sill
This requires curtains to end roughly 15 cm below the windowsill.

Floor Length
Floor length depends on what style you prefer, but you usually want your curtains to end 1 cm above the floor.
