Vertical blinds are the answer for windows wider than they are tall. Where a roller or roman would be heavy and awkward across a broad span, a vertical hangs fabric vanes from a top track that rotate for light control and slide aside to open - which also makes them the natural fit for patio doors you walk through. This guide covers how they work, where they suit, and three picks spanning all-round use, breadth of choice and light-filtering fabric.

What a vertical blind is

A vertical blind suspends fabric vanes - typically 89mm or 127mm wide - from a track at the top of the window. The vanes rotate in unison to control light: angled, they admit daylight from the side while keeping a degree of privacy; closed, they overlap for shade; turned flat, they let the view through. The whole set also draws to one side, stacking the vanes together to clear the glass or doorway entirely.

That combination - rotate for light, slide to open - is what makes verticals suited to wide openings and patio doors. A single wide roller would be a heavy, unwieldy thing to raise; a vertical handles the same span easily and parts like a curtain for door access.

The format carries a faintly commercial association - verticals are common in offices - so they suit some interiors more than others. In a contemporary or practical room they look at home; in a soft, traditional one, curtains or a roman may sit better. The vanes can also sway in a draught, though most ranges weight the bottoms and link them with a chain to limit it.

What to look for

Window proportions. Verticals earn their place on wide windows, bays and patio doors. On a standard upright window, a roller or venetian usually looks neater - the vertical's strength is span.

Fabric opacity. Verticals come in standard, light-filtering and blackout fabrics. A bedroom with a wide window wants blackout vanes; a living room or conservatory often wants light-filtering for daytime privacy with brightness. Some ranges also offer fire-retardant fabrics, which matter for rented or shared accommodation.

Vane width. Wider vanes (127mm) give a bolder, more contemporary look and fewer joins; narrower (89mm) give finer control and a more traditional appearance. Both work; it is a question of proportion and taste.

Operation and draught. Check the range includes bottom weights and a linking chain, which keep the vanes hanging steadily. For a door in constant use, smooth slide and open operation matters.

Room. Verticals suit living rooms, dining rooms, conservatories, offices and wide bedroom windows. PVC vane options exist for kitchens and bathrooms where moisture is a factor.

Trinity

A wide-palette vertical from 247 Blinds suited to patio doors and bays.

from £15.85 in 69 colours

For an all-round vertical, the Trinity vertical from 247 Blinds is our pick. It is built around blackout and fire-retardant fabrics in a wide range of colourways, which covers the most common needs in one range: darkness for a wide bedroom window, FR compliance for rented or shared spaces, and a broad palette for everything else. It has live price grids, so you can cost it at your size now.

The blackout colourways make it genuinely useful for a wide bedroom window - otherwise an awkward thing to darken - while the neutrals suit living rooms and offices. Check whether a given colourway is the blackout or FR version, as that decides its suitability for your room.

Where colour choice leads, the Sevilla vertical from Blinds 2go offers a broad and brighter palette, including a number of blackout fabrics. It spans soft neutrals and greys through to brights like Candyfloss, Shiraz and Kingfisher, which makes it the pick for a wide window where you want the blind to add colour across its span rather than recede.

It is keenly priced for a vertical. Like Trinity, it includes blackout options for bedrooms; the difference is emphasis - Sevilla leans into palette breadth where Trinity leans into blackout and FR fabrics. Compare the two on the specific colour and fabric you need.

Excel Light Filtering Vertical

Excel Light Filtering Vertical

at So Easy Blinds

A light-filtering vertical from So Easy Blinds.

from £33.75 in 123 colours

Read review →

For a wide window where you want softened daylight and privacy rather than darkness, the Excel vertical from So Easy Blinds is our light-filtering pick. Its fabrics diffuse daylight and give daytime privacy while keeping the room bright - the right choice for a living room, conservatory or office, where a blackout would just make the space gloomy. The palette is exceptionally broad, with over eighty colourways, so precise matches are possible.

It sits above budget verticals in price, reflecting the fabric and the choice. It is the wrong pick for a bedroom needing darkness - light-filtering fabric passes daylight by design - but for daytime living spaces it is well-judged.

What we didn't include

We have kept this to three picks covering all-round use, choice and light-filtering. A note on the gaps.

We have not included a PVC vertical for kitchens and bathrooms, though wipe-clean vane options exist. That is a fabric specification to look for within a range rather than a separate pick - if your wide window is in a wet room, ask for a PVC or moisture-rated vane on whichever range suits.

We have also not included a panel blind, which is an adjacent option for very wide openings. Panels slide as solid sections rather than rotating like vanes, so they give a different kind of control - cleaner-looking on a very broad expanse, but without the fine light-angling that makes a vertical useful. For most wide windows and patio doors, the vertical's rotation is the more flexible choice, which is why this guide stays with verticals.

Price by your window

The from-prices shown are starting points; a vertical's made-to-measure price depends on the width and drop, and a wide patio door will sit well above the entry figure. Each pick's page carries a price-by-dimensions tool - enter your measurements for the price at your size. Trinity is priced live now; the others fill in their grids shortly.
