How to Measure & Install Roller Blinds in Dubai

Measure from the front face of the reveal to the back wall. You need a minimum of 60mm clear depth — ideally 70mm+ — for the bracket and the rolled-up blind to sit entirely inside the reveal when fully raised. If you have less than 60mm, switch to outside mount. This is a hard limit, not a guideline.

Measure the inside width of the reveal at three points: at the top, the middle, and the bottom. Dubai windows are not always perfectly square — tile adhesive, plaster, or frame installation can make the bottom narrower than the top by several millimetres. Use the smallest measurement of the three. This is the maximum blind width that will fit without jamming.

Deduct 10mm from your smallest width measurement — 5mm each side — to allow the blind to operate freely without the fabric or roller tube touching the reveal walls. This is the width you order. Your supplier's blind will be manufactured so the fabric is slightly narrower again than the overall unit width; confirm the exact deduction with them when ordering.

Measure from the top of the reveal (where the bracket will sit) to the windowsill. For floor-length blinds that drop below the sill, measure to the floor instead. This measurement is your fabric drop. Most suppliers add a small amount to this for the hem bar weight at the base — confirm with them at order stage.

For a standard light-filtering blind: add 50mm each side beyond the window frame. For a blackout blind: add 75–100mm each side. The extra width means the fabric overlaps the wall surface rather than ending at the frame edge, eliminating the side light gaps that defeat the purpose of a blackout blind. Bigger overlap = less light leakage = better blackout.

Measure the window opening (glass edge to glass edge, or frame outer edge to outer edge — whichever you're using as your reference point) and add your side overlap on both sides. That total is your blind width. Double-check this measurement twice before ordering — fabric cut to the wrong width can't be fixed.

The bracket position above the frame determines where the blind starts. Standard practice is 50–80mm above the top of the window frame. Mounting higher makes the window look taller and leaves more of the glass clear when the blind is raised. For a floor-to-ceiling effect, mount the bracket at ceiling height or as high as the wall allows.

From the underside of the bracket to your end point — sill, floor, or below-sill. For sill-length blinds, end 10–15mm above the sill to avoid the fabric resting on the sill surface, which looks untidy and can cause the blind to not roll up straight. For floor-length, end 10mm above the floor.

Use a pencil and spirit level to mark where the brackets will go. Most roller blind brackets have two fixing holes each. Mark all four points, check with the spirit level that the two brackets are perfectly level with each other, and adjust before drilling. A spirit level check here takes 30 seconds and prevents a tilted blind that will drive you mad for as long as it hangs there.

This cannot be overstated. Every wall in a Dubai apartment or villa, including the wall above the window frame, is reinforced concrete or masonry block. A hammer drill with a masonry bit is non-negotiable. Set the drill to hammer mode, use the correct bit size for your wall plugs, and drill to a depth slightly greater than the plug length. Blow out the dust before inserting the plug.

Dubai buildings route electrical conduit and plumbing through the concrete walls, often close to window frames where they're hidden under plaster. Drilling into a conduit is dangerous; hitting a rebar is both a drill-bit killer and structurally bad. Use a stud and cable detector before drilling anywhere you're not certain is clear. They cost AED 60–120 from any hardware shop and are worth every dirham.

Dubai's standard aluminium window frames look like they'd be easy to drill into, but they're often hollow sections that sit on an internal frame. Drilling through the visible aluminium face can crack the section, damage the seal, and void any remaining warranty on the window unit. Fix brackets to the wall above or beside the frame — not to the frame itself — unless you're using frame-mounted clips specifically designed for aluminium sections.

Dubai's temperature swings — from 20°C in January interiors to 38°C in summer near an unshaded west-facing window — cause aluminium blind components to expand and contract slightly. This is factored into quality blind designs, but it's a reason to avoid very tight inside-mount tolerances. That 10mm deduction on reveal width isn't just for clearance — it also accommodates minor thermal movement over the life of the blind.

Check the blind matches your order — width, drop, fabric, chain side. Unroll a section of fabric to confirm the colour and fabric are correct in your actual room light. It's much easier to raise a return at this stage than after four holes are drilled in your wall.

Hold the brackets against the wall at your planned positions. Mark through the fixing holes with a pencil. Then use a spirit level across both bracket marks to confirm they're perfectly horizontal. Adjust one bracket position up or down until the level reads true. This step takes two minutes and makes the difference between a straight blind and a sloping one.

Set the hammer drill to hammer mode. Use the correct masonry bit for your wall plug size (usually 6mm for the plugs supplied with blinds). Drill to the depth of the plug plus about 5mm extra — the extra depth lets you tap the plug fully flush without it splitting. Blow out the hole with a puff of breath before inserting the plug.

Tap the wall plugs in gently with a hammer until flush with the wall surface. Position the bracket over the plug holes and screw in firmly — the screw should feel solid as it grips the plug expanding in the concrete. Don't overtighten to the point of cracking the bracket. Repeat for the second bracket and check both are level and secure before proceeding.

Roller blind brackets have a fixed side (usually with a square socket for the drive pin) and an open or spring-loaded side (for the idle end of the tube). Identify which side of your blind is which — the drive side carries the chain. Slot the drive pin into the fixed bracket first, then push the idle end of the tube into the open bracket until it clicks or locks. Give a gentle tug to confirm it's secure before releasing.

Roll the blind down to its fully lowered position and check the hem bar is level. Roll it back up fully. Pull it halfway down — does it hang straight? Check that the chain operates smoothly, the limit stops (if fitted) work at both top and bottom, and the fabric isn't touching the reveal walls on either side. Any adjustments are far easier now than after the furniture's back in position.
