Blackout fabric is woven tightly or given a coated backing so daylight cannot pass through the material itself. The catch is that a blind is not a sealed box: light still leaks in around the edges, where the fabric has to sit a little narrower than the recess to move freely, and along the top of the roll or stack. Even a good blackout fabric in an ordinary recess leaves a visible glow around the edges, so it is honest to think of it as deep shade rather than total darkness.

Where that edge light matters most - nurseries, shift workers sleeping in the day, media rooms, bright south-facing bedrooms - the answer is to seal the sides. Look for side channels or blackout tracks, a framed style such as perfect-fit or a roof blind held in channels, or a face-fixed blind cut to overlap the reveal. One real limit: slatted and louvred blinds (venetian, vertical) and layered day-and-night blinds cannot truly black out, because the slat tilts, cord holes and sheer bands always pass some light however dark the fabric. For genuine darkness, rollers, lined romans, channelled pleated and roof blinds get closest.

Two things help when you are choosing. The darkness comes from the coating or the tight weave, not the shade, so a pale blackout fabric blocks just as well as a dark one - pick the colour you want and let the cloth do the work. And blackout is really about light rather than warmth or noise, though a dense fabric does take a little of the chill and the echo out of a room as a welcome side benefit. If a blind is sold as a blackout venetian or a blackout vertical, read that as the darkest the style manages, not a promise of a dark room.

If a properly dark room is the goal, two fittings make the biggest difference: choosing a face fit cut to overlap the opening by a good margin on every side, or adding side channels that the fabric runs inside. Both close down the edge gap an ordinary recess blind leaves, and they matter far more to the result than the grade of fabric on its own. Measure for that overlap before you order, because a blackout blind cut to the bare opening will always leave the thin line of light at the edges you were trying to be rid of.

A roller blind is a single piece of fabric wound on a tube that rolls up out of the way and down to cover the window, worked by a side chain or a spring. It is the simplest made-to-measure blind and, because it uses the least fabric and the plainest mechanism, usually the cheapest at any given size. That simplicity is also its strength: it suits almost any room, sits neatly in or over a recess, and there is very little to go wrong.

Fabric choice does most of the work. Rollers run the whole range from sheer voiles through light-filtering weaves to full blackout, and moisture-resistant PVC-coated fabrics make them a sensible pick for kitchens and bathrooms where a wipe-clean surface helps. Light behaviour follows the fabric, though the roll always sits slightly narrower than the recess, so a little light slips down the edges whatever you choose. Care is easy - a wipe with a damp cloth, or a sponge for the coated fabrics - and against the neighbouring types a roller typically undercuts a roman or a wood venetian for the same window.

On the practical side, you can have a roller on a side chain, on a spring you pull down and let glide back up, or on a quiet motor worked by remote or app. It needs only a shallow recess to sit in, so it fits the tight reveals that defeat bulkier blinds, and a cassette or fabric-wrapped pelmet tidies the roll at the top where the look matters.
