Some fabric names circulate the UK blinds trade the way certain paint colours circulate rental flats, and Metz is one of them - it appears at four retailers we track, which makes it one of the most widely stocked plain rollers in the country. At Blinds By Post the range runs to 6 shades from £8.84, with a cassette version and a motorised cassette listed alongside the standard blind. If you have stood in a hallway anywhere in Britain and not noticed the roller blind, there is a fair chance it was something like this.

Who it suits

Metz is the workhorse specification. The palette runs strictly from White to Black with no detours, which is exactly what landlords, offices and serial window-dressers want: a blind that matches the next room, and the next, without a colour decision in sight. As a plain roller it keeps the format's usual virtues - one flat cloth, nothing to snag, the whole thing rolled up out of the way when the light is good.

The two extra formats each earn their place. The cassette encloses the roll in a headrail, so the top of the blind reads as a clean bar rather than a bare tube - worth having where the blind sits at eye level on stairs and landings. The motorised cassette does away with the operating chain entirely, which is the tidy answer for windows above sofas or sinks and settles the dangling-cord question in children's rooms. Whichever format you pick, confirm the opacity on the listing before promising anyone a dark bedroom.

The colours

6 colours available

Fitting

Moon is the shade this range is known by - if the Metz name rings a bell at all, it is probably Moon doing the ringing - and around it the card keeps to a strict monochrome scale: White and Ivory at the pale end, Stone and Ash in the middle ground, Black to anchor it. There is no accent shade and no pattern, and that is the point. Choosing between six disciplined neutrals is really a question of undertone - Ivory sits warmer than White, Stone warmer than Ash - and undertones are precisely what screens misreport, so order a couple of samples and check them against the window wall in daylight before committing.

Metz starts at the accessible end of made-to-measure pricing, which is a large part of how it earned its ubiquity. From there the figure moves with width and drop, and the format matters too: the cassette and motorised versions are listed as products in their own right, so price the one you actually intend to fit. Measure the recess in three places, take the smallest figures, and let the grid above do the translation for your window.

How it compares

On Blinds By Post's own shelves, Metz is the straight-edge option: where the shop's gentler roller palettes deal in pastels and soft mid-tones, this one keeps to the White-to-Black spine and lets the room do the talking. Pick it when the brief says dependable; look elsewhere when the brief says warmth or character.

The wider comparison is where Metz gets interesting, because so many shops stock it. The same fabric name appears at Blinds Direct, Roller Blinds Direct and Wilsons Blinds, and the price for the same cloth at the same window differs between shops - sometimes trivially, sometimes not - with the order liable to reshuffle as sizes change. Our Metz comparison lines the four up at your measurements; with a fabric this widely stocked, a minute spent comparing is rarely wasted.

A note on care

A monochrome palette is candid about housekeeping: Black shows every fleck of lint and White shows every shadow of grime, so little and often beats occasional heroics. A soft brush or the vacuum's upholstery head over the lowered cloth keeps the surface honest, and marks want blotting with a barely damp cloth - hard rubbing polishes pale fabric into shiny patches. Let the blind dry fully before it rolls away, keep the cassette slot free of dust so the cloth is not dragged past grit twice a day, and give a motorised blind a full top-to-bottom run now and then to keep the mechanism sweet.
