How to measure for curtains
Whether you're refreshing a room or adding the finishing touches to a space, the right curtains can pull everything together. But before you start shopping, it’s essential to measure properly – no one wants curtains that are too short or long. Here’s a simple guide to measuring for curtains to help you get the right fit every time.
Step 1: Choose your curtain length
Before you reach for the tape measure, think about the look you want to achieve. Do you prefer sleek, floor-length curtains that skim the ground, or something a bit tidier, like windowsill curtains? The style you choose will impact how and where you measure, so decide this first.
Types of curtain lengths
Choosing the right curtain length can transform the feel of a room in an instant. Whether you're aiming for a polished finish or something with a touch of drama, these styles will guide your choice:
1. Floor-length curtains
Floor-length curtains create a classic, elegant vibe, sitting 1-2cm above the floor for a sleek finish. Ideal for living rooms or large windows, they offer a sophisticated drape that enhances any space.
2. Windowsill curtains
Windowsill curtains sit just above the sill, providing a tidy finish. Perfect for kitchens or bathrooms, they combine style and practicality. Aim for about 1cm above the sill, adding extra for uneven windows or a tailored look.
3. Apron curtains
Apron curtains hang slightly below the sill, balancing casual and elegant styles. They're perfect for windows with radiators beneath, allowing heat circulation. Hang them about 10-15cm below the sill for the best effect.
4. Puddle curtains
Puddle curtains add drama by hanging 2-6cm longer than standard floor-length styles, creating a fabric “puddle” on the floor. Ideal for luxurious spaces, such as formal dining rooms.
Step 2: Choose your heading style
The heading style of your curtains can affect your measurements. Different headings hang in distinct ways, so here’s a quick guide:
Eyelet curtains: With metal rings that thread onto the pole, eyelet curtains start just below the pole. Measure from the top of the pole to your desired length, remembering to account for the ring’s depth for a precise drop.
Pencil pleat curtains: These hang from hooks attached to rings on a pole or directly from a track. Measure from the eye of the hook (on a pole and rings) or from the top of the track to your desired length.
Tab top curtains: Tab tops hang from fabric loops that keep the pole visible. Measure from the top of the pole to your desired length for a laid-back yet stylish finish.
Pro tip: Always double-check your heading style before finalising your measurements – this small detail can make a big difference!
Step 3: Measure for your curtains
How to measure for eyelet curtains
Step 1: Measure the drop (length)
When measuring for eyelet curtains, consider how you want them to hang. Whether they touch the floor or sit just above the sill, precise measuring is key.
For floor-length curtains: Measure from the top of the pole to the floor, then subtract 1cm for clearance.
For windowsill curtains: Measure from the top of the pole to the windowsill and subtract 1cm.
For apron curtains: Measure from the top of the pole, then add 10–15cm.
For puddle curtains: Measure from the top of the pole to the floor, then add 2–6cm for extra drape.
Step 2: Measure your window width
Measure the width of your window recess, adding 15-20cm on either side of the window (this is so your curtains have space to sit neatly when open). This will be your curtain pole length.
Now, you’ll need to measure your curtain pole to calculate your curtain width.
Step 3: Measure your curtain pole
Simply measure the width of your curtain pole between the finials (decorative end caps). To get your final curtain width, double the measurements - this is to ensure a full, gathered look.
How to measure for pencil pleat curtains
Step 1: Measure the drop (length)
For pencil pleat curtains, always measure from the eye of the curtain ring. If your pole isn’t installed yet, use 15cm above the window frame as a reference for where it will sit.
For windowsill curtains: Measure from the eye of the ring to the sill, subtracting 1cm.
For apron curtains: Measure from the eye of the ring to 10-15cm below the windowsill.
For floor-length curtains: Measure from the ring’s eye to the floor, subtracting 1cm for clearance.
Step 2: Measure your window width
Measure the width of your window recess, adding 15-20cm on either side of the window (this is so your curtains have space to sit neatly when open). This will be your curtain pole or track length.
Now, you’ll need to measure your curtain pole or track to calculate your curtain width.
Step 3: Measure your curtain track or pole
If you have a curtain track: Measure from one end of the track to the other. Double the measurements for a full, gathered look.
If you have a curtain pole: Measure the width of your curtain pole between the finials (decorative end caps). Double the measurements for a full, gathered look.
How to measure for tab top curtains
Tab top curtains bring a casual, stylish touch, with the pole visible between the tabs. Choose a decorative pole for added style.
Pro tip: Since tab tops are threaded directly onto the pole, the pole’s diameter is crucial. A thicker pole can cause the fabric to bunch, making it harder to open and close. Aim for a pole diameter that leaves at least 1-2cm of space between the tabs for smooth movement.
Step 1: Measure the drop (length)
Measure from the top of the pole to where you want your curtains to end. Curve the tape measure around the pole’s diameter for accuracy.
For floor-length curtains: Measure from the top of the pole to the floor, then subtract 1cm for clearance.
For windowsill curtains: Measure from the top of the pole to the windowsill, then take off 1cm.
For apron curtains: Measure from the top of the pole to the sill, then add 10–15cm.
For puddle curtains: Measure from the top of the pole to the floor, then add 2–6cm for extra drape.
Step 2: Measure your window width
Measure the width of your window recess, adding 15-20cm on either side of the window (this is so your curtains have space to sit neatly when open). This will be your curtain pole length.
Step 3: Measure your curtain pole
Now, you’ll need to measure your curtain pole to calculate your curtain width. Simply measure the width of your curtain pole between the finials (decorative end caps). To get your final curtain width, double the measurements. This is to ensure a full, gathered look.
Step 4: Double-check your measurements
Now that you’ve got your measurements, take a moment to double-check! It's easy to rush through this step and end up with curtains that don’t fit quite right. A quick review now can save you from any surprises later. Measuring for curtains might seem like a small step but getting it right can transform your room. With the perfect length and width, your curtains will frame your windows beautifully, creating a look that suits your style. Grab your tape measure and get started – your perfect curtains are just a few steps away.
