The Stellar Perfect Fit Blind is a made-to-measure roller blind sold by 247 Blinds in a no-drill perfect-fit format - meaning it clips directly into the rubber gasket of a UPVC double-glazed window rather than being screwed to a wall or ceiling. There are 10 colourways available, starting from £29.57, all drawn from a measured neutral palette.

Who it suits

The no-drill fitting makes this range most useful for renters, or for anyone who would rather not put holes into a UPVC frame. Because a perfect-fit frame grips the window's rubber seal, the blind sits flush with the glass - there is no overhang onto the wall and no gap on the sides that you would get with a standard recess or face-fit installation. That close contact also reduces edge light-leak more than a conventionally fitted roller can manage without side channels.

This format is best suited to bedrooms and living rooms where the UPVC frames are in reasonable condition and have the recess depth to accept the clip-in frame. It is less appropriate where the window frame is timber or aluminium - perfect-fit installation relies on the specific rubber gasket found on modern UPVC double glazing. The range is also unlikely to suit a bathroom, where a PVC roller fabric would be a more practical choice; the brief does not confirm the Stellar's fabric is moisture-rated, so confirm with the retailer before ordering for a wet room.

The colours

10 colours available

The eight finishes - Coconut, Gris, Lily, Relic, Shade, Sterling, Wheat, and Vanilla - sit firmly in the neutral-to-warm-neutral register. There are no strong accent colours here. Coconut, Vanilla, and Lily are at the white and off-white end; Wheat and Sterling move into warm grey and greige territory; Gris and Shade lean cooler and mid-grey; Relic sits in a slightly deeper warm tone. The overall effect is a range designed to recede into a room rather than make a statement - useful when the window treatment is meant to coordinate with a variety of furniture finishes rather than lead the colour scheme.

Price by your dimensions

Enter your window size. We round up to the next standard size, which matches how the retailer actually quotes you.

With a from-price of £29.57, the Stellar sits towards the accessible end of the perfect-fit market. Perfect-fit blinds generally carry a small premium over equivalent standard rollers because the clip-in frame is included in the price. As with all made-to-measure blinds, the price you pay will depend on the exact dimensions you order - the grid above shows how the price scales across common width and drop combinations.

How it compares

Against a standard recess-fit roller blind at a comparable price, the Stellar offers a cleaner sightline and better edge coverage at the cost of compatibility - you need UPVC frames with the right gasket to use it. If your windows are UPVC and you are installing in a room where no-drill fitting matters, the perfect-fit format is a meaningful advantage over a conventionally fitted roller at a similar price.

If you need strong light control for a bedroom, confirm the Stellar's opacity rating with the retailer before ordering - the opacity class is not stated in the product listing we reviewed, so check whether the fabric is dimout or blackout before committing. Fabric weight can also vary across finishes within the same range, so it is worth verifying each colourway individually if guaranteed darkness matters.

Fitting and operation

Because perfect-fit blinds clip into the window gasket rather than fixing to a wall, there is no drilling and no permanent alteration to the frame. The blind is also removable without trace - a practical consideration in rented properties or where access to the full window pane is occasionally needed. The mechanism sits within the clip-in frame, which means the blind operates in the same way as a standard roller (typically a side-chain or spring-assisted pull) once installed.

One point to check before ordering: the recess depth of your specific window unit. The perfect-fit frame adds depth in front of the glass, and some shallow UPVC units do not have enough room to accept it without the frame fouling the handle or restricting the window from opening. 247 Blinds will typically publish minimum recess requirements in the product fitting guides.
