Four words, one question
Blind fabrics are usually grouped by how they treat light. The terms are not perfectly standardised, so one supplier's dim-out can be another's light-filtering. But the idea behind each is consistent, and knowing it can help you feel confident when you choose.
The question underneath all of them is: how much do you want to see out, how much do you want others to see in, and how dark does the room need to be?
Screen fabrics
A screen fabric has an open weave, a bit like a very fine mesh. It cuts glare and softens the sun but keeps a view of the outside while the blind is down. Think of it as sunglasses for the window.
- Good for: living rooms, home offices, kitchens and conservatories where you want the view and daylight but less glare.
- Worth knowing: daytime privacy is partial, and at night with the lights on, people outside can often see in. For rooms where you want privacy after dark, screen fabrics pair nicely with something else.
- Tip: darker screen fabrics usually give a clearer view out, while lighter ones tend to give more privacy. Ask to see a sample in your own window.
Filtering fabrics
Sometimes called light-filtering, these let daylight in but diffuse it. They are solid enough to block clear views through the fabric, though some outline or shape can show, especially at night. They bring a gentle, even light into the room.
- Good for: dining rooms, kitchens, hallways and bathrooms where you want a bright room with daytime privacy.
- Worth knowing: with a light on inside and darkness outside, a filtering fabric can show silhouettes. It also lets sunlight through, so a bedroom, or a room where you watch a screen in the afternoon, may suit another fabric better.
For ideas on keeping rooms bright and private, see privacy without darkness.
Dim-out fabrics
Dim-out sits in the middle. The fabric is denser and cuts much more light than a filtering one, so the room goes noticeably dimmer, but it does not aim to remove light fully. You can usually tell it is daytime through the fabric.
- Good for: bedrooms where you want a calmer, darker room but not pitch black, spare rooms, nurseries and snug TV rooms.
- Worth knowing: some light may still come through the fabric and around the edges, depending on the blind and the fitting. If you work shifts or want the darkest possible room, blackout may suit you better.

Blackout fabrics
A blackout fabric is built to stop light passing through the material. It is often thicker, and many are coated or layered. This is a lovely choice when darkness matters.
- Good for: bedrooms, nurseries, shift workers and media rooms.
- Worth knowing: light can still find its way in at the edges, between the blind and the frame, or through the headrail gap, so the room may not be completely dark. How much depends on the blind type and how it is fitted. Our bedroom light control guide explains the leaks and the fixes. For privacy, a good dim-out can be just as helpful as a blackout fabric.
There is also a style point. Blackout fabrics often have a smoother, flatter finish than lightweight ones, and the range of textures can be narrower. See blackout blinds.
Which room, which fabric
- Bedroom. Blackout or dim-out. Think about early summer mornings and your own sleep pattern.
- Living room. Screen or filtering for day, with a curtain or second blind if you want evening privacy and darkness.
- Kitchen. Filtering is a common choice. Look for a fabric you can wipe. See kitchen blinds.
- Bathroom. Filtering in a fabric designed for damp rooms, or a slatted option. See bathroom blinds.
- Home office. Screen or filtering to tame glare. See home office blinds.
- Conservatory. Screen or filtering for daytime. See conservatory blind choices.
Other things worth knowing
Colour changes the result
The same fabric type in white, grey or a dark tone behaves differently. Light colours diffuse and glow, dark colours absorb and give a clearer outward view. Read how to pick blind colour and look at our colours and fabrics page.
Texture and weight
A heavier fabric hangs flatter, while a very light one can ripple or curl at the edges. It affects the look and, on some blinds, how they roll.
Sun and ageing
Fabrics in strong sun age differently depending on their make-up. See sun glare and fading.
Layering
Two layers can solve problems one fabric cannot. A filtering blind for the day with a blackout one behind, or a screen blind in front of a curtain. It is common in bedrooms and conservatories. Day and night blinds do something similar within one blind. See day and night blinds.
Try a sample first
Fabrics look different in a swatch, in a shop and on your window. It can help to hold a sample against the glass, in the morning and in the evening, with the light on and off. We can bring samples to a free home measure so you see them in the room. Book a free measure and we'll talk through which suits each window. Ranges and fabrics vary, so ask us what is available for the blind type you want.
