How to Choose Living Room Curtains That Work Harder

Curtains do far more than soften a window. They affect how much daylight enters the room, how private it feels after dark and whether the window looks considered or slightly unfinished. They can also make a noticeable difference to the perceived height and width of a living room.

The best choice depends on the window, the room’s use and the amount of maintenance you are happy to take on. Before choosing a colour or pattern, work through the practical decisions first: where the pole will sit, how far the fabric should extend and what level of light control you need.

Start with the way the room is used

A living room that faces a busy pavement needs different curtains from one overlooking a private garden. Think about the room at several times of day rather than choosing based only on how the fabric looks in a shop or sample book.

• For daytime privacy: consider a close-weave fabric, a voile layer or curtains that can be drawn across the glass without making the room dark.
• For a bright, south-facing room: a lined curtain can help reduce glare and protect furnishings from strong direct sun.
• For a room used for watching films: prioritise a heavier lining or a curtain with a dense weave, particularly if the television sits opposite the window.
• For a draughty period property: fuller curtains with a thermal or interlining option may make the window feel more comfortable in colder months, although they will not replace properly maintained glazing and seals.

Also note how often the curtains will be opened. If they need to move every morning and evening, a straightforward track or smooth-running pole may be more convenient than a delicate heading that is difficult to operate.

Choose the right curtain length

In most living rooms, full-length curtains create the most finished appearance. They draw the eye upwards and give a window more presence, even when the glass itself is fairly modest. Measure from the position of the pole or track rather than from the top of the window frame.

There are three useful approaches to the hem:

• Just above the floor: the hem finishes roughly 1cm above the floor, giving a clean line and making vacuuming easier.
• Breaking slightly: the fabric reaches the floor and forms a small, relaxed fold. This can look softer but needs careful measuring so the curtains do not appear accidentally too long.
• Pooling: extra fabric rests on the floor. It suits a deliberately relaxed or traditional room, but it collects more dust and is less practical where the curtains are opened frequently.

Avoid stopping curtains at the windowsill unless the room layout genuinely requires it. Short curtains can look awkward beside full-height furniture and may make a window feel disconnected from the rest of the room. If a radiator sits below the window, check that long fabric will not trap heat unnecessarily or interfere with the controls.

Position the pole beyond the window frame

Mounting the pole or track only inside the window recess can make the opening look smaller and leaves less room for the curtains when they are open. Where the wall allows, extend the pole beyond both sides of the frame. This lets the fabric sit beside the glass instead of covering it and makes more of the window available for daylight.

Fix the pole several centimetres above the window, rather than directly along the top edge. The exact distance depends on the room and the position of the ceiling, coving or lintel, but the general aim is to create a clear vertical line without making the treatment look squeezed against the ceiling.

Check the wall before drilling. Plasterboard, masonry and older plaster may require different fixings, and a wide or heavy pair of curtains needs secure support in more than two places. If the pole must be fitted close to a ceiling or around a bay window, a track can sometimes be more flexible than a standard pole.

Calculate the width for a fuller finish

Flat fabric stretched across a window rarely looks generous enough. Curtains need extra width so they form folds when closed and gather neatly at the sides when open. To calculate the approximate fabric width, measure the track or pole rather than the window and multiply that measurement by the fullness recommended for the curtain heading.

As a broad guide, eyelet curtains often need less fullness because their folds are more controlled, while pencil pleat, pinch pleat and wave headings may require different amounts. Always check the maker’s measurement guidance before ordering, as finished width and pair width are not described consistently across retailers.

Remember to allow for the space needed beside the window. If the curtains are intended to stack outside the glass, the pole may need to be wider than expected, particularly with thick fabric. A narrow stack can cover a surprising amount of daylight when the curtains are open.

Pick a fabric and lining that suit the light

Fabric changes the mood of a room, but it also changes how the curtains hang. Linen and linen-look materials bring a relaxed, lightly textured finish, although some crease more readily than tightly woven cotton or polyester blends. Velvet has a substantial drape and can help a room feel cosier, but its weight may require stronger hardware.

Ask for a sample and hold it against the window at different times of day. A colour that looks soft in a showroom may appear much stronger against daylight. Check the reverse side too, especially if the curtains will be visible from outside.

Lining is equally important. An unlined curtain usually allows more light through and can suit a bright, informal room. A standard lining gives the fabric more body and helps colours look more even. A blackout lining is useful where light control matters, but it can make some fabrics feel heavier and may not be necessary for a living room that is mainly used during the day. Interlining adds another layer between the face fabric and lining, creating a fuller appearance and additional insulation at the window.

Use colour and pattern with the whole room in mind

Curtains do not need to match the sofa, but they should relate to at least one or two existing elements. This might be a wall colour, a timber tone, a rug, a lampshade or a small accent used elsewhere in the room. Repeating a colour loosely is usually more flexible than trying to find an exact match.

If the living room already contains strong pattern, a plain textured curtain can provide useful quiet space. In a simple room, a stripe, check or botanical pattern can give the window more character without requiring a complete redecoration. Use a sample to judge the scale of the pattern against the size of the window; a small repeat can look busy across a wide expanse, while a large motif may lose its impact on a narrow window.

For a calm result, compare the curtain colour with the wall in both daylight and artificial light. A close tonal relationship makes the window recede, while a stronger contrast turns it into a focal point. Neither is automatically better: the choice depends on whether you want to highlight the architecture or keep attention on furniture and artwork.

Check the details before ordering

Measure each window separately, even if they appear identical. Older homes often have small differences in width, height or level. Record the finished measurements, the pole or track type, the curtain heading and whether the measurements refer to one curtain or the pair.

Look at care instructions before committing to a fabric. Curtains that need specialist cleaning may be less convenient in a busy family room, while washable fabrics still need to be removed and rehung carefully to avoid creasing. Decide whether you want a simple hand-drawn treatment or a corded, baton-operated or motorised option, particularly for wide windows.

Good living room curtains should look right when open as well as closed. Prioritise a secure fitting, enough width to frame the glass and a length that suits the floor. Once those practical choices are right, colour and texture become much easier to judge.
