Your shades have arrived, the box is on the floor, and somewhere inside it are two small brackets that look far too small to hold anything. This is the part people quietly dread. It is also, genuinely, the easy part.
Here is how to install roller shades in about fifteen minutes a window: mark a level line, drive four screws, click the shade in. Two brackets, one drill, one level. If you have ever hung a picture frame straight, you already have the only skill that matters.
The rest is detail — the real tool list, the steps for both mounts, the four mistakes that cause crooked rolls, and what to do when something looks wrong. Every spec below comes from Off Cut Shades' own factory installation sheets, downloadable for your exact hardware from our installation guides, and is current as of August 2026.
Tools and Time: The Honest List
Our installation guides page lists what you need, and it is short:
- A metal tape measure
- A pencil
- A drill with the right bits for your wall
- A Phillips screwdriver
- A level — the page calls this "recommended", but treat it as required
- A step ladder, if the window is high
That is the whole kit. No specialist tools, no second person.
About the fifteen minutes: it is a fair number for a standard-width shade going into a wooden frame on two brackets. It is not a fair number for your first window ever — add ten while you get the feel of it — or for a very wide shade that needs five brackets, or for anything going into concrete. Do the first one slowly. The rest genuinely go fast.
Before the drill comes out, do the two things our install sheets put ahead of everything else: check that every part listed on the sheet is in the box, and check that the shade's dimensions match your order and your window.
How to Install Roller Shades: Inside Mount
Inside mount sits the shade inside the recess — the neater look, and the one most people want. It needs roughly 2 inches of flat depth inside the frame, more with a cassette or valance. The measuring guide has the depth rules; if you have not ordered yet, read inside mount vs. outside mount first.
1. Work out how many brackets you need. Our cassette installation sheets set this by shade width, and as of August 2026 the counts are: under 60 inches, two brackets; 60 to 96 inches, three; 96 to 120 inches, four; 120 to 148 inches, five; over 148 inches, six. Space them evenly across the width, and keep the two outer brackets no more than 2 inches in from the ends of the cassette.
2. Find the clutch end. Hold the shade up and note which side the chain or motor sits on. On our open-roll system the brackets are universal — either one accepts the clutch or the pin — but the shade still only goes in one way round. On older hardware where the two brackets are different parts, a clutch on the left means you reverse the bracket positions, left for right.
3. Mark the first bracket. Hold it inside the recess, tight to the top and to the side, and pencil through the screw holes.
4. Draw the level line. Carry that first mark across to the other bracket positions with the level. This is the one rule the whole job rests on. Our sheets require the brackets to be level and aligned with each other, and note that shimming may be required — so if the frame is out of square, which frames often are, a thin shim behind one bracket is the correct fix, not a bodge.
5. Drill pilot holes. A small pilot at each mark keeps the screw from wandering off your line and a wooden frame from splitting. The step people skip and then regret.
6. Screw the brackets in and re-check level before you touch the shade. Two screws are far easier to move now than later.
7. Click the shade in. With a cassette, front face toward you, hook its back edge onto the bottom of each bracket, then start at the centre and push back and up until it snaps in. You should hear an audible click at every bracket. With an open roll, put the spring-loaded pin end in first, keep gentle pressure on it, then lift the clutch end and drop its two hooks into the two slots in the bracket, pulling down gently to seat it. The bottom of the clutch should point straight down.
8. Test the roll. All the way down and up, twice. Operate from the centre of the bottom bar — off-centre pulling is what makes fabric telescope to one side, and on Zero Gravity spring shades it matters even more.
9. If it has a chain, fit the safety shield. Not optional. The loop holder and joint piece screw into the wall or window frame and keep the chain taut. Our sheets carry the standard warning for a reason: young children can be strangled by cords, and any cord longer than 22 cm or a loop more than 44 cm around must not be left accessible.
Outside Mount: Wall and Ceiling
Outside mount puts the shade on the wall above the opening, overlapping it by 1.5 to 3 inches per side. It is the fix for shallow recesses, out-of-square openings and light gaps, and needs a flat surface above the frame to land on.
The steps are the same with two additions. First, decide your top line before you mark anything — how high above the frame the shade sits determines the finished look, so hold it up, pick the height, mark one end and carry it across with the level. Second, leave breathing room: for a wall mount our sheets ask for about a quarter inch between the ceiling and the bracket, and for a ceiling mount about a quarter inch between the wall and the bracket. That gap is what lets you take the shade down again in five years without fighting it.
On what to screw into: get into wood wherever you can — the frame or the molding — because it holds better than anything you can add to drywall. If there is only drywall behind the bracket, use a wall anchor rated to carry it. Our sheets deliberately do not name a hardware type, because the right anchor depends on your wall, so if you are unsure what is behind yours, ask us before drilling rather than after.
And if you live in a condo with concrete lintels, be realistic: that is a masonry bit, plugs, more dust and more patience. Very doable, but not the fifteen-minute version.
The Four Mistakes That Cause Problems
Brackets that are not level. The cause of almost every crooked roll. The fabric tracks toward the low side and creeps further over with each cycle until one edge rides up the tube. The fix is the prevention: level the brackets and shim the low one.
The wrong number of brackets, or uneven spacing. On a wide shade, too few brackets lets the cassette sag in the middle, and the roll follows the sag. Count off the widths above and keep the outer pair within 2 inches of the ends.
Skipping pilot holes. A screw driven straight into hard wood wanders, and a bracket two millimetres off your mark is a bracket that is no longer level. Ten seconds a hole.
Forcing the mechanism. If the shade does not click in, something is not lined up — usually the pin end is not fully seated, or the clutch is not sitting straight down. Back it out and re-seat it. Our 5-year warranty covers manufacturing defects but specifically excludes problems caused by improper installation, so the two minutes you spend not forcing it are well spent.
Renter Notes
The honest version: yes, this puts holes in your window frame. Four small screw holes for a standard shade — the same holes a curtain rod bracket leaves. Filler, a fingertip and five minutes fixes them on the way out.
What we will not do is guess about your lease. If drilling is not allowed where you live, talk to us before you order rather than after.
If Something's Wrong
The shade rolls crooked. Check the brackets with a level before anything else.
The shade does not fit the window. If you mis-measured, our SureFit™ Measurement Guarantee is the safety net: contact us within 14 days of receiving your order and we will work out the best fix, often a remake at a significant discount. Details on our guarantees page.
Something looks or feels faulty. That is a warranty question, not an install question.

Frequently Asked Questions
What tools do I need to install roller shades?
A metal tape measure, a pencil, a drill with the right bits, a Phillips screwdriver, a level and a step ladder if the window is high. That is the full list from our installation guides page — nothing specialist on it.
How far apart should roller shade brackets be?
Evenly across the width, with the outer brackets no more than 2 inches from the ends of the cassette. The count goes by width: two under 60 inches, three from 60 to 96, four from 96 to 120, five from 120 to 148, six above that (as of August 2026).
Do roller shades need drilling?
Yes. The brackets screw into the window frame, the wall or the ceiling — four small screws for a standard shade, and the holes patch easily.
Can one person install roller shades?
For a normal window, comfortably. A very wide or heavy shade is easier with someone holding one end, but the marking and drilling is a one-person job either way.
Why does my roller shade roll crooked?
Nine times out of ten the brackets are not level, so the tube runs slightly downhill and the fabric drifts. Level them and shim the low side. If it simply rolls the opposite way to what you expected, that is roll direction rather than a fault — see reverse roll shades.
Fifteen Minutes, Two Brackets, Done
Mark the line, keep it level, pilot the holes, click it in. That is the entire job, and the only part that rewards care is the level line.
