White Curtains: Choosing the Right White, Weight and Lining

Curtain whites fall roughly into three groups. Optic or brilliant white is the cleanest, coldest white, usually achieved with bleaching and optical brighteners. Soft whites, ivory and cream carry a little warmth. Natural whites, sometimes sold as ecru, oatmeal or undyed, keep some of the fibre's own colour, which in linen is a pale grey-beige.

The wall decides most of it. Hung against a brilliant white wall, an ivory curtain can look faintly dirty. Hung against a warm, lime-washed wall, an optic white curtain can look blue and hard. Against a coloured wall, almost any white reads as white, and the question becomes whether you want the window to look crisp, which favours a cleaner white, or soft, which favours a warmer one. If in doubt, match the undertone of the curtain to the undertone of the wall.

There is also the question of how each white ages in sun. The Drycleaning and Laundry Institute explains that many fabrics are naturally off-white and are bleached, and that optical brighteners are often added to make them look whiter; those agents can break down, letting the fabric revert to its natural off-white or yellowish colour, and light breaks them down only where it falls. A brightened white curtain on a sunny window can therefore yellow unevenly, in the folds that face the sun. A natural or soft white has less to lose and ages more evenly.

A sheer white curtain is about the light. Drawn across a window by day, it diffuses sun, softens glare and blurs the view in from outside while keeping the room bright. The Building America Solution Center, run by Pacific Northwest National Laboratory, describes sheer shades as providing very effective daylighting and glare control while keeping a softened view out.

At night it reverses. Privacy from a sheer depends on the outside being brighter than the inside, so once the lamps are on, anyone outside can see in, sometimes in sharp detail. This is the commonest complaint about white sheer curtains, and it is a matter of physics, not quality. A denser, semi-sheer weave helps a little; a second layer is the real answer for any room overlooked after dark.

A lined white curtain is about privacy and body. The lining makes it opaque, helps it hang in fuller folds and protects the face fabric from sun. It still glows softly when the sun is on it, especially in linen or a loosely woven cotton, but it no longer shows the room. With a blackout lining, the room goes dark; the white face is then purely about how the window looks from inside.

The arrangement that solves most white-curtain problems is two layers on one double track. The sheer hangs on the window side and stays drawn through the day. The lined curtain hangs on the room side and closes at dusk, or on the hottest afternoons. The window has a day setting and a night setting, and both are white.

Keep the two whites in the same family. An optic white sheer in front of an ivory lined curtain looks like a mistake; a natural linen sheer with an oat or soft white lined curtain looks deliberate. Texture can differ, and usually should: a fine voile against a slubbed linen, or a crisp cotton against a soft sheer, gives a white window depth without colour.

Plan the track for both. A double track needs a little more depth from the wall and more stacking space either side, because two layers bunch up when open. A ceiling track with a ripple-fold heading keeps both layers in even folds and stacks narrowly. You can try sheer and lined combinations on your own window in our sheer curtain simulator, and our layered curtains page shows the options we make.

Goa's dry season is bright. The India Meteorological Department's climate summary records skies that are generally clear or lightly clouded from November to April. Direct daylight is intense: the Canadian Conservation Institute gives about 30,000 lux for average daylight against roughly 500 lux in an office, and notes that the rate of light damage rises in proportion to intensity. White fabric has no dye to fade, but light and ultraviolet still act on it. The Institute lists the weakening and eventual fragmentation of cotton, silk and wool among the effects of ultraviolet, and yellowing among the typical results. A cotton sheer that has hung in a west window for years can become fragile at the folds that face the sun, even if it still looks white.

Near the sea, salt haze leaves a fine, slightly sticky film on everything, and white fabric shows it first as a dull grey cast. Inland, the red-brown dust of laterite country settles along hems and the lower edges of curtains in the dry months, tinting rather than greying them. In the monsoon, the risk is mildew: small dark spots that start where fabric stays damp against a wet window or a cold wall.

Hardware leaves its own marks. Plain steel hooks, rings and rods rust in salt air, and a rust stain on a white curtain is very hard to remove. For white curtains near the coast, specify aluminium tracks and stainless or coated fittings, and check that weights sewn into the hem are coated too.

Most white sheers are polyester voile, and for good reason. It washes easily, dries quickly, does not shrink much and is available in wide widths, so long runs need no vertical seams. Linen-look polyester gives the slubbed texture of linen with the same practicality. For a rental or a sea-facing room, these are the safe choice.

Cotton white curtains are soft, matt and breathable, and they take a crisp, clean look well. They also shrink if washed hot, crease, and, as the Canadian Conservation Institute notes for cotton generally, weaken under long exposure to ultraviolet. Lining them protects the face fabric and helps them last.

Linen in white is the most beautiful and the most demanding. Bleached white linen has a cool, crisp look; natural linen is a warm grey-beige that many people find easier to live with. Linen moves with humidity, relaxing and lengthening in the wettest months and drawing up again in the dry, so floor-length linen curtains need a hem allowance and a little patience. Our sheer and voile fabric guide compares the options in more detail.

From outside, a window is judged by its back. With a sheer, the street sees the sheer itself, usually a uniform white. With a lined curtain, the street sees the lining. A white or ivory lining makes every window in the house look consistent, whatever colour the curtains are inside, which is why it is the standard choice and why many apartment buildings prefer it.

If you choose white face fabric unlined, the street sees the face, and that is fine as long as it is genuinely white and kept clean. If you line a white curtain, choose the lining's white to suit the face fabric, since a bright lining behind an ivory face can shine through as a slightly different shade when the sun is on it. For blackout, most linings have a white or off-white back; ask to see the side that will face the glass.

In buildings with a rule or custom about how windows look from outside, a white lining nearly always satisfies it. If you are unsure, ask the building's managing committee before ordering rather than after.

White curtains go grey slowly and then all at once. The Drycleaning and Laundry Institute notes that greying is most often caused by soil that has not been fully removed over many washes. Short, cool cycles with too little detergent leave a little dirt behind each time. Wash white curtains on the warmest cycle the care label allows, with enough detergent, and rinse well.

Skip the bleach. The same Institute warns against chlorine bleach on whites, because it makes optical brighteners break down faster, so the fabric can end up yellower rather than whiter. It also advises avoiding light exposure while drying, since light breaks down brighteners in the exposed areas. Dry white curtains in the shade with good airflow, not spread in full sun on a terrace, and rehang them slightly damp only if the room is dry and airy enough for them to finish drying quickly.

In a homestay or rental, keep a second set. White sheers in a guest room need washing more often than in a family home, and in the monsoon they can take days to dry. Two sets let one go to the wash while the other hangs, so the room is never bare between guests. Before a house closes for the rains, take white curtains down, wash them and store them dry and loosely folded in cotton, not plastic; our monsoon take-down and storage service does this for owners who are away.
