The six kinds of blind, told by the way they move

Movement first, fabric second

Walk into any showroom and the choice appears to be about colour and texture — hundreds of swatches, a handful of finishes, and somewhere behind them six actual machines. The swatches are the easy half. Two of the six machines will suit your window and four will not, and no fabric can rescue a mechanism doing a job it was never built for.

The four movements sort everything. A blind can roll onto a tube, tilt on its slats, fold into pleats or cells, or slide along a track. Each verb buys one ability and charges for it somewhere else, and every entry below is honest about both sides of that ledger — including the window where each mechanism is the wrong answer, because a list without the failures is a brochure.

The ones that roll: roller and zebra

The roller blind is the simplest machine in the range and the hardest to improve on: one plane of fabric, one tube, nothing else in view. When it is up it almost ceases to exist — a slim cassette at the head of the window — which is why modern rooms with good glass tend to end up here. It also carries the widest fabric spectrum of any mechanism, from open solar screens that keep a view while cutting glare, through decorative mid-weights, to full blackout for the rooms where morning is the enemy.

What the roller cannot do is nuance. It is up, or down, or an unsatisfying horizontal compromise between the two; there is no angle, no aiming, no half-truth. A room whose light changes all day will find that limit weekly.

The zebra blind exists precisely at that limit. Alternating bands of sheer and solid fabric run in two layers on one roller, and moving the layers past each other tunes the alignment continuously — solid on solid for privacy, sheer on solid for a soft glow, anything between. It turns the roller’s switch into a dial, which is why it has become the default answer for street-facing rooms that refuse to choose between daylight and dignity. Its limits are two: it is not a blackout product, and after dark, with the room lit, sheer bands show silhouettes to the street. Evening rooms close it fully or back it with something solid.

Both rollers share one practical footnote — the fabric wraps a tube, and the tube needs recess depth. A very shallow window frame can rule the movement out before taste has a say, and a zebra needs more depth again because its double layer fattens the roll.

The ones that tilt: venetians in aluminium, wood and faux wood

Every other mechanism in this guide decides how much window to cover. The venetian decides something different: where the light that enters should go. Its horizontal slats rotate in place, so the same window at the same hour can send its light onto the ceiling — brightening the room while killing glare at seated eye level — or angle it at the floor, or shut flat. Nothing else in the range can redirect light at all, and for dim rooms, north faces and home offices with eye-level glare, that single talent settles the argument.

The material decides the character and the room. Aluminium is thin, inexpensive and moisture-proof — the practical answer over a sink. Real wood brings weight and warmth and reads as furniture, but timber and steam disagree over time, so it stays out of bathrooms. Faux wood copies the timber look in a polymer that shrugs at humidity, at the cost of extra weight on wide spans.

The mechanism’s honest tax is maintenance: several dozen slats are several dozen ledges, and dust treats them as an invitation. A household that will never take a cloth to them twice a year will be happier with a roller, and we say so in living rooms when it is true.

The ones that fold: roman and cellular

Two mechanisms share the folding verb and could not be less alike in purpose.

The roman shade folds for beauty. Raised, it gathers into deep horizontal pleats of real fabric; lowered, it hangs nearly flat. It is the one blind that reads as soft furnishing rather than hardware, and in bedrooms, dining rooms and any space that a flat panel would leave feeling unfinished, that is the entire argument.

Lined well, it also does respectable work on darkness and warmth. Its cost is stack: those pleats have to live somewhere when the shade is up, and they live across the top fifth or so of your glass, permanently shading the highest — and most useful — band of daylight. On a generous window nobody notices. Over a kitchen sink, the roman is how you lose the garden.

The cellular shade folds for physics. Seen from the side its fabric is a row of honeycomb cells, and each cell holds a pocket of still air between the room and the glass — which is to say it is insulation that happens to be a window covering. On a cold Toronto window it is the only mechanism whose warming claim is structural rather than aspirational, and a double-cell version doubles the trapped air for the rooms where February is the actual complaint. Many run top-down as well as bottom-up, covering eye level while daylight enters above. Its cost is plainness: the face is deliberately quiet, and lowered, it is an opaque panel — the view and the warmth take turns.

The ones that slide: vertical blinds and panels

Wide glass defeats everything above. A lifting blind spans its window like a beam, and past roughly two and a half metres the engineering starts arguing back — tubes deflect, weights multiply, and one opening becomes two blinds pretending to be one. Doors are worse: a covering that parks across the top of a doorway has to be raised and lowered every single time anyone passes.

The sliding movements sidestep the whole problem by stacking sideways. Vertical blinds hang free-swinging vanes from a headrail track: drawn, they clear the opening entirely to one side; closed, they tilt like a venetian turned ninety degrees, so a covered door still admits an adjustable amount of light. They remain the most practical object you can put on a sliding door, a fact untouched by two decades of their being called dated. Panel track systems run the same idea through fewer, wider, flat fabric panels and read considerably calmer in a modern room. And drapery — which this company also makes and installs — is the softest member of the sliding family, with the best night privacy of anything on this page when lined and generously stacked.

The family’s shared weakness is the gaps. Light and sightlines pass between vanes and around panels by design, so none of the sliders is a blackout answer, and a draughty room will set unweighted vanes swaying.

Reading your own window before anyone measures it

Four checks, all doable in a minute with no tools, tell you most of what the measure will confirm.

Depth. Look at how far the glass sits back from the wall face. A shallow recess rules out inside-mounted rollers and zebras before anything else is discussed; a deep one opens every option, including the tight blackout fits that make bedrooms genuinely dark.

Width. Pace it. Past about two and a half metres you are shopping the sliding family, or accepting a split into two lifting blinds on one line.

The hour. This site’s favourite question, because it chooses the movement faster than any showroom can. Morning-dark wants rolling blackout or folding cells; all-day adjustment wants zebra bands or tilting slats; evening low sun wants something that aims or drops to a height.

The traffic. If the opening is walked through, it slides. No exception has ever survived contact with a family using a patio door in July.

What the visit adds is the part a page cannot: the millimetres, the squareness, the crank handles and alarm sensors and radiators that ambush stock sizes, and fabric samples held against your own light rather than photographed under somebody else’s. The measure is free, and if the honest answer at your window is the plain roller — the cheapest machine on this page — that is the answer you will hear.

If you would rather start from the problem than the machinery, the companion guide chooses the best blind by the hour it has to win — same range, approached from your side of the glass.
