How to Choose Blinds for Privacy: Day, Night and Room by Room

Privacy from a blind comes down to one question most people never ask in the showroom: what does this look like from the footpath at 9 pm with the lights on? A fabric that seems perfectly private at noon can be a lit stage at night. Here's how each blind behaves after dark, and which one to put where.

A black blockout roller in a bedroom. Nothing through the fabric, day or night — the only light or sight line is around the edges, and the fit takes care of that.

The night test

By day, the outside is brighter than the inside, so almost any fabric hides the room. At night it flips: the room is lit, the street is dark, and anything translucent shows silhouettes or a full view. So there are really two privacy questions — daytime privacy, which is easy, and night-time privacy, which is where blinds are chosen well or badly.

The quickest way to know how a fabric behaves is to order a free sample, tape it over a window, turn the room lights on after dark and walk outside. Two minutes, and you'll never argue about it again.

Which fabrics pass

Sunscreens and sheers earn their place for view and glare, so the usual answer for a room you live in is a pairing — a double roller with sunscreen and blockout on one bracket, or a sheer curtain with a blockout roller behind it.

The tilt trick: venetians and shutters

Slatted products give you something fabric can't: privacy and light at the same time. Tilt the slats of a venetian or the louvres of a plantation shutter upwards and someone at street level sees the underside of the slats and the ceiling, while daylight still bounces into the room. Fully closed, they're close to opaque, with a little light at the slat edges. The trade-off is that a tilted slat is never as sealed as a blockout fabric, so for a bedroom that needs to be dark, add a blockout behind or pick a roller instead.

Room by room

Gaps: where privacy actually leaks

The fabric is only half of it. A blind that stops 50mm short of the frame, or sits inside a recess with a strip of glass showing each side, gives a passer-by exactly the sliver they'd need. Three fixes:

The belt-and-braces version: a sheer in front, a double roller behind. Daytime softness, night-time seal, and the track runs past the window so nothing shows at the edges.
