Curtains or blinds? Room by room.

A lot of people search for blinds and curtains in the same breath, because when you move into a new house in Pakenham or Officer, every window is bare at once and the question is simply how to cover them. The honest answer is that most homes end up with a mix. The question is which window gets which.

This guide works through the differences that actually matter in daily life: how much space each takes, how each handles light, privacy, warmth and moisture, and how each suits particular rooms and awkward windows. It finishes with a planner you can fill in for the whole house. We make curtains, sheers and tracks, not blinds, so where a blind is the better fit we say so and leave it there.

An honest starting point

Curtains are fabric hung from a track or rod that draws sideways. Blinds are a panel or set of slats that moves up and down or tilts, usually fitted inside or just outside the window frame. That one difference, sideways versus vertical, drives almost everything else. A curtain needs wall space beside the window to stack into when open, and projects forward from the wall. A blind needs space above or inside the window, and sits flat.

Neither is better in general. A curtain softens a room, absorbs sound, frames a window and can make a room look taller. A blind is compact, clean-lined, and happy in places where fabric is a nuisance. The right choice depends on the window and how the room is used.

What actually differs

Warmth deserves a note, because it is where claims get muddled. The federal energy.gov.au guidance recommends close-fitting lined curtains or blinds, with pelmets. Both can work. The difference is in how easy it is to get a close fit. A curtain on a ceiling-fixed track, extended past the frame with returns, can reduce gaps at the top and sides when the heading and returns fit closely. Most blinds leave a small gap at each side, and inside-fitted blinds leave the frame and reveal exposed. The thermal curtains guide explains why those edges matter.

Privacy after dark

One thing catches out a lot of new home owners in their first winter. Sheer curtains and light-filtering blinds can provide daytime privacy, depending on fabric openness, viewing angle and the brightness difference, because the outside is brighter than the inside and people looking in see mostly reflection. At night that reverses. With the lights on inside and dark outside, a sheer or a light-filtering blind shows silhouettes and, close up, a fair amount of detail. Street-facing living rooms and bedrooms on corner blocks are where it matters most.

The fix is the same whichever product you choose: a second, opaque layer for the evening. With curtains that means a double track, a sheer for the day and a lined or blockout curtain for the night. With blinds it means a blockout blind, or a blockout blind behind a light-filtering one on a double bracket. A curtain double track is usually simpler to use on wide glass, while a double blind suits a narrow window with no stack space. Decide this before ordering, because adding a second layer later often means replacing the track or brackets that were fitted for one.

Space and projection

The most common reason a curtain is the wrong answer is space. When a curtain is open, it gathers at the side of the window. If there is no wall there, because of a corner, a cupboard, a door frame or a bed head, the stack sits on the glass and blocks light and view. Lined curtains stack deeper than sheers, and heavier headings stack deeper than lighter ones. A blind rolls or folds up above the glass and leaves the wall clear.

Curtains also project into the room. A track with a wave or pleated heading sits some distance off the wall, and the curtain adds more. That usually does not matter, but it does next to a door that swings across the window, a desk pushed against the wall, or a window with a winder handle.

Room by room

Living room. Usually curtains. Living rooms tend to have the widest glass, often a sliding or stacker door, and the most hard surfaces: tiles or timber-look floors, big windows, a television. A curtain across that wall softens the sound in the room and can close the whole wall at night for warmth. Sheers on a wave track give daytime privacy from the street without losing light. Where the living area has a small window squeezed between a corner and a cabinet, a blind can be the better choice for that window alone. Our sliding door guide covers door curtains in detail.

Main bedroom. Usually curtains, often layered. A bedroom needs darkness at night, privacy in the day and warmth in winter. A blockout curtain on a ceiling track with returns can provide useful edge coverage, depending on the competing blind design and its fit, which matters for sleep. A sheer in front gives daytime privacy. If the bed head sits hard against the wall beside the window, check stack space before deciding. The blackout bedroom guide explains the fitting.

Children's rooms and nurseries. Either can work, with conditions. Darkness usually favours a well sealed curtain. Cord safety applies to both, and both need cords secured out of reach. Children also pull on curtains, so both track and rod fixings need to suit their support and the expected load; ceiling fixing is not automatically stronger.

Kitchen. Usually a blind, or nothing. Windows over sinks, benchtops and cooktops are poor places for fabric. A curtain there cannot reach the floor, gets splashed and greasy, and near a cooktop it is a fire risk. Curtains only make sense in a kitchen for a door or window in the dining end, clear of the bench.

Bathroom and laundry. Usually a blind in a moisture-tolerant material, or frosted glass. Steam and splashes are hard on fabric and encourage mould on hems and linings. A sheer can work in a large, well-ventilated bathroom with a window away from the shower, but it is the exception.

Study or home office. Either. Glare on screens is the main problem, and a sheer or a light-filtering blind both deal with it. If the desk sits under the window, a blind avoids fabric dragging across the desk. If the room doubles as a guest room, a curtain gives the darkness a bedroom needs.

Formal rooms and older homes. Usually curtains. High ceilings, tall windows and period detailing in the older parts of Beaconsfield, Garfield and the townships suit curtains with a sewn heading such as pinch pleat. The heading guide covers the options.

When to use both

A blind and a curtain on the same window is not overkill in the right room. The blind sits in the recess and handles daytime light and privacy, raised or lowered as needed. The curtain hangs in front on a ceiling track and is drawn at night. The curtain covers the blind's side gaps for darkness and warmth, and softens a room that would otherwise feel bare. It suits bedrooms where someone wants a crisp blind by day but needs a properly dark room at night, and living rooms facing a busy street.

If you already have blinds you are happy with, adding a curtain in front is often a better upgrade than replacing them. Check that the blind's controls and the curtain's projection do not clash: the curtain track needs to sit far enough forward to clear the blind's chain and any headbox.

Awkward windows

Windows next to a corner. Stack space is limited on one side. A one-way draw curtain that stacks entirely to the open side can work. If neither side has space, a blind is usually better.

Awning and casement windows with winders. Curtains need to clear the handle, which pushes the track forward. Fine for most, but a deep winder handle can catch a sheer.

Bay windows. Curtains on a bent track follow the bay and keep the seat or floor clear. Individual blinds in each pane are another route, but leave gaps at each angle. Bays are measured on site.

High or raked windows. Windows above head height are hard to reach, and both curtains and blinds there usually need motorisation or a wand. See the motorised curtains guide.

Doors that open into the room. A French door that swings inward will catch a curtain unless the track is extended well past the frame so the stack clears the door swing. A blind fitted on the door itself moves with it.

Cords and children

Corded curtains and corded blinds are both covered by Australia's mandatory safety standard for corded internal window coverings, and loose cord loops are a real risk to young children whichever product you choose. The practical rules are the same for both: cords secured out of reach, cleats or tensioners fitted, and furniture kept away from windows in children's rooms. Our curtain safety rules page sets out what applies. Wand-drawn and motorised curtains can avoid an accessible operating cord, but still check power leads and any other reachable cords.
