Measure Once, Hang Beautifully: Avoid Curtain Regrets
Good curtains can completely change how a room feels. They soften hard edges, frame the daylight, and make evenings feel cosy, especially as the weather cools and the nights draw in. The right fabric and colour can turn a plain space into somewhere you actually want to curl up with a book or a hot drink.
Small measuring mistakes can spoil that feeling. Being just a few centimetres out can leave you with curtains that look mean and skimpy, drag untidily on the floor or let in more light than you wanted on a bright morning. It is frustrating, and it can be expensive to fix.
The good news is that curtain measuring is simpler than it seems. With a tape measure, a notepad and a few clear steps, you can get a made-to-measure look, even with ready-made curtains. Our aim is to share those steps so you can enjoy a designer finish at home, without guessing or stressing about numbers.
We are a friendly, family-run team here in the UK, and we spend a lot of time helping people match curtains to their favourite designer homeware in the UK. Think of us as the calm voice that keeps you from cutting corners, so your new curtains feel like they truly belong in your home.
Start at the Top: Getting Your Curtain Pole Right
Before you even pick a fabric, you need to get the pole or track in the right place. This is what gives your curtains room to hang properly and makes the window feel taller and wider.
As a simple rule, many people like to:
- Fix the pole around 10 to 15 cm above the top of the window frame
- Extend it at least 15 to 20 cm past each side of the frame
- Check there is enough space above and to the side for the curtains to move freely
Hanging the pole too low is a very common mistake. It can make the ceiling feel lower and the window look squat. Not allowing space either side of the window for the curtains to stack back is another. That is when the curtains cover a chunk of the glass even when they are open, blocking light.
For heavier fabrics, or lined curtains that have a bit of weight, it is important to check the wall can take strong brackets. In older UK homes, walls can be a mix of solid and hollow areas, so it is worth taking your time and, if needed, asking a professional fitter to help.
When you measure the pole width, measure the full length from finial to finial, or the full track if you are using one. For bay windows and tricky corners, break each part into sections, measure each one, then add them together. It feels less scary when you treat it as a few simple lines rather than one big odd shape.
The finish of the pole can also help pull your room together. For example, sleek metal poles tend to sit nicely with bold, modern prints from brands like Scion Living, while a warm wooden pole can work beautifully with classic patterns from Morris & Co and other heritage looks.
Measuring Curtain Width Without Guesswork
A lot of width mistakes happen because people measure the glass only. For curtains, you should always measure from the full pole or track length, not just the window opening.
Curtains also need what we call fullness. Put simply, if you buy curtains that are exactly the same width as the pole, they will look flat and mean when closed. To get that soft, full look, you normally want more fabric than the pole width.
As a rough guide:
- Pencil pleat curtains often look best at around 2 times the pole width
- Eyelet curtains usually work well at around 1.5 to 2 times the pole width
- Tab top styles can sit a little flatter, so closer to 1.5 times the pole width
Common mistakes include ordering curtains that add up to no more than the glass width, not allowing for overlap in the middle when using a track with two halves, and forgetting that thick fabrics and linings need extra space to push back.
Different heading styles sit differently on the pole. Pencil pleat hangs from hooks, so the top of the curtain can hide the pole slightly. Eyelets slide directly onto the pole and create even, deep folds, so they naturally give a fuller look without needing quite as much extra fabric. Tab tops sit in simple, straight folds, so if you want them to feel generous, aim for a wider width than you think.
Getting the Drop Right: Lengths That Look Tailored
Once you have the width clear, the next task is the drop. This is where many people slip up, either by forgetting where to measure from or by ignoring what is under the window.
The three most popular curtain lengths are:
- Sill length, stopping just above the window sill
- Below-sill, finishing a little below the sill
- Floor length, either just touching or slightly pooling on the floor
Sill-length curtains work well in busy spaces like kitchens, where long fabric might get in the way of worktops or sinks. Below-sill is helpful where there is a radiator under the window, as it keeps the fabric away from the heat. For living rooms and bedrooms, floor-length is often the most elegant choice.
How you measure the drop depends on your heading and hardware:
- For a track, measure from the top of the track to your chosen finish point
- For pencil pleat on a pole, measure from the bottom of the curtain rings
- For eyelets, measure from the very top of the pole, then add the extra above the eyelet if you want the fabric to sit higher
People often forget to allow for the heading and end up with curtains that sit awkwardly high or puddle too much. Floors are rarely perfectly level, especially in older UK homes, so it can be wise to measure from a couple of points and use the shortest one as your guide.
Think about anything in the way too. Radiators, window seats, sofas or beds can all affect where the curtain should finish.
As we move into autumn, slightly longer curtains that just kiss the floor or pool softly by a couple of centimetres can feel very cosy. Rich fabrics and designer prints from brands like Orla Kiely or Sara Miller work beautifully at this length, adding colour and warmth while framing the darker evenings.
Tricky Windows, Pattern Matching and Lining Choices
Some windows are more awkward than others. Bay windows, patio doors and extra-wide openings can look overwhelming at first, but they are easier when you break them down.
For bays, measure each straight section of the track or pole separately rather than trying to guess one long curved width. For patio or French doors, measure the full frame, then add extra both above and to the sides so the curtains can clear the glass when open. Extra-wide windows sometimes need more than one pair of curtains or a track that allows for smooth movement.
Pattern scale matters too. Many designer homeware patterns in the UK, like those from Sophie Allport, Wrendale Designs or Portmeirion, have a clear repeat. If your curtains are too short or too narrow, the design can look cut off. Giving the pattern enough space helps it breathe and makes it a real feature in the room.
Lining choices also play a big part in how your curtains look and feel:
- Standard lining softens the fabric and gives a nicer drape
- Blackout lining helps block light, useful for bedrooms and TV rooms
- Thermal lining adds an extra layer, helpful for keeping rooms snug as days get cooler
Linings can change how bulky the curtain is when stacked open, so remember this when deciding on fullness and pole length.
To finish the room, many people like to echo curtain colours in other textiles. Cushions, throws and bedding from the same or related designer ranges can make the whole space feel thoughtful, without being too matchy.
From Tape Measure to Cosy Room: Your Next Steps
Once you have worked through each stage, it helps to pause and double-check. Ask yourself:
- Is the pole high and wide enough to make the window feel bigger?
- Did you measure the full pole or track width, not just the glass?
- Have you chosen a drop that suits the room and what sits under the window?
- Does your heading style, pattern choice and lining all work together?
Write your measurements down clearly, label each one and keep the notes with you when you are looking at curtains, bedding and other accessories. It saves a lot of guesswork later.
