The Complete Guide to Blockout Curtains for Australian Bedrooms

There's a reason bedroom curtains are one of the most searched window covering topics in Australia. Get them right, and you barely think about them. Get them wrong, and you're lying awake at 5am wondering why summer light feels so personal.

This guide covers everything you need to know, from why blockout matters, to how it differs from blinds, to what to look for in children's rooms. And if you're anywhere near the end of a decision, we'll show you why custom-made is the only version worth considering.

Why blockout matters in the bedroom

Sleep quality and light are more connected than most people realise. Even low levels of ambient light, streetlights, early morning sun, headlights, can interrupt your sleep cycle without you noticing. You wake up tired and don't know why.

Blockout window coverings are designed to stop that. Not reduce light. Stop it.

For anyone working night shifts, travelling across time zones, or parenting young children who wake at dawn, proper blockout isn't a luxury, it's the difference between functioning and not. But even if you're a solid sleeper, a bedroom that stays dark in the morning just feels better. Cooler in summer, too, because good blockout fabric also acts as a thermal barrier.

The question isn't really whether you need blockout. It's which type suits your bedroom best.

Blockout curtains vs blockout blinds: which is right for bedrooms?

Both blockout curtains and blockout blinds can do the job, but they suit different rooms and different people.

Curtains suit bedrooms where softness and texture matter. The weight of the fabric, the way they hang floor to ceiling, the way they frame a window, it all adds up to a room that feels considered and lived in. They're also generous in coverage, which helps with light seal around the edges.

Blinds are typically more precise and practical. Blockout blinds suit bedrooms where space is tight, or where you want something clean and minimal. Roller blinds with a quality blockout fabric, fitted flush to the recess, can achieve excellent light block, but the feel of the room is different.

The honest answer? A lot of bedroom windows work really well with both. That's why seeing them in your actual space, your light, your walls, your room, matters more than any description on a screen.

Fabric and lining options

Not all blockout curtains are created equal, and the difference usually comes down to the lining.

Blockout lining is the most common approach: a standard fabric face with a specialised lining sewn in behind it. It gives you the full aesthetic freedom of any fabric, woven, textured, sheer-face with blockout backing, while the lining handles the light.

Some fabrics are made to block light all on their own, no separate lining needed. They tend to be slightly thinner and work well in bedrooms where you want a cleaner, more minimal look.

Thermal-lined curtains combine blockout properties with insulation. In Melbourne, where winter mornings are cold and summer afternoons are genuinely hot, this is worth thinking about. In Brisbane and Adelaide, where afternoon western sun drives up room temperature and humidity makes a poorly insulated room uncomfortable fast, a good thermal lining earns its keep. The right lining can meaningfully reduce room temperature fluctuation, which is good for sleep in any climate.

One thing to note: fabric colour and pattern on the face of the curtain has almost no impact on blockout performance. It's all in the lining. So you don't have to choose between a room that looks good and one that stays dark.

Heading styles: a detail that makes a real difference

Most people don't think about heading style until someone mentions it, but it's one of the decisions that most affects how well a blockout curtain actually performs.

Pencil pleat and pinch pleat headings stack tightly and sit close against the wall or track. That snug fit is exactly what you want for blockout, it minimises the gap at the top of the curtain where light would otherwise creep in. They're the right call for any bedroom where light control is the priority.

S-wave headings have a gentle, flowing curve that looks elegant, and works beautifully for sheers or light-filtering curtains where that open, airy feel is the point. But the shape of the wave creates a larger gap between the curtain and the wall, which means more opportunity for light to get through. For blockout, it's the wrong tool for the job.

Our consultants will always talk through heading style as part of the consultation, it's one of those details that's easy to get right when you know what to look for.

Children's bedrooms: what to consider

Children's sleep is a different challenge. Daytime naps, early bedtimes, and the sheer stubbornness of a toddler who's spotted daylight at 6am, blockout in a child's room isn't optional.

A few things to think about:

Light seal around the edges. This is where a lot of off-the-shelf options fall short. A custom-made curtain, fitted properly to your exact window, eliminates the gap at the top and sides where light sneaks in. That gap is small. For a two-year-old, it's enough.

Durability. Children's rooms get more wear. Look for fabrics that are easy to wipe down, and linings that won't deteriorate with regular washing.

Fabric content. If your child has sensitivities, ask about fabric composition. Our consultants can point you toward options that are suitable.

Room-darkening vs full blockout. Some parents prefer very dark, full blockout, others want something that keeps the room dim but doesn't create complete darkness for older children. There's a range, and it's worth being specific about what you actually want.

Why custom-made makes a difference

Off-the-shelf curtains are sold in standard drops and widths. Your windows are not standard. That gap, between what's sold and what your window actually needs, is where light gets in, and where the whole effect falls flat.

Custom-made blockout curtains are cut to your exact measurements. They hang from floor to ceiling properly. They cover the full width of your window, with enough overlap on each side to do the job. They look like they belong there, because they were made for there.

The other thing custom-made gives you is choice. Not just from a catalogue page, but real choice, fabric, lining weight, heading style, track or rod, with someone who knows what they're looking at standing in your room, helping you decide.

That's what our in-home consultants do. They come to you, bring samples, take measurements, and give you a quote before they leave. No showroom trip. No guessing from a screen. Just good advice in your home.
