Measuring guide · Indoor roller blinds
Reading time: 8 minutes
Every window is different, which is why we make our roller blinds to measure for the space you want to cover.
This guide shows you what to measure, in what order and how to arrive at the measurement to enter in the configurator, so your blind fits with no surprises.

PREPARATION
You only need a few tools. Have ready:
Each blind is made to measure, within these limits:
STEP 1
If something gets in the way of the fabric as it comes down, in most cases you can simply switch from wall fitting to ceiling fitting.
Before measuring, check that the fabric can come down without touching anything. In particular, look at:
With wall fitting, if the windowsill sticks out from the wall by more than 8 cm, the fabric touches it on the way down, before reaching the bottom.
Choose ceiling fitting and fix the bracket far enough from the wall to clear the windowsill.
If the handle sticks out from the wall by more than 8 cm, the fabric touches it on the way down.
Measure how far it sticks out. If it's more than 8 cm, choose ceiling fitting and fix the bracket further from the window.
When tilted open, the sash leans into the room and can hit the brackets or the fabric.
Open the window in this position and measure how far the sash sticks out from the wall. If it's more than 8 cm, choose ceiling fitting and fix the bracket further from the window.
If the radiator sticks out from the wall by more than 8 cm, the fabric rests on it.
Measure how far it sticks out. If it's more than 8 cm, choose ceiling fitting and fix the bracket further from the wall, or give us the measurements for a shorter blind so that it stops above the radiator.
If there's an air vent near the window, the lowered blind mustn't cover it. In many rooms, for example where there are gas appliances, the vent is there for safety.
Check where the vent is in relation to the fabric. Choose the width, height or fitting type so that it stays clear.
Poles, tracks, pelmets and brackets from old blinds can take up the space needed for the brackets or get in the way of the fabric.
Measure how much space they take up. If you want to keep them, choose a fixing point that leaves room for both systems.
Air conditioners, wall lights, shelves or furniture can take up the space needed for the brackets or stop the fabric before it reaches the bottom.
Check that the fixing point and the fabric's whole path are clear, and that the blind doesn't block the air conditioner's airflow. If the item can't be moved, change the fixing point or the width.
Allow space to open the window
With the blind raised, the bracket and bottom bar take up 10.5 cm in height: this is the space you need above the window, to open it without hitting the blind.
With wall fitting, the gap between the wall and the fabric is about 8 cm: check that the sash, the handle or the windowsill don't stick out further than that.


SO, WHAT DO YOU NEED TO DO?
Check that the fabric can come down freely.
⚠ WARNING
Check for pipes and electrical cables before choosing the fixing point.
There may be hidden pipes or wiring where you want to fix the bracket.
STEP 2
Before taking any measurements, decide where you'll fix the bracket: on the wall or on the ceiling.

The bracket is fixed to the wall, above the window. With this fitting the fabric hangs about 8 cm from the wall.

The bracket is fixed directly to the ceiling. It's the right choice when there isn't enough space on the wall, or when the blind needs to hang more than 8 cm away from the wall.
SO, WHAT DO YOU NEED TO DO?
Decide where to fix the bracket before you measure.
STEP 3
In the configurator you can give the width in two ways (see the drawing below):


You know how wide you want the fabric to be. We add the space taken up by the brackets.
So measure the width of the glass, or of the whole frame if you want to cover it.
We recommend adding 10 cm of overlap
We recommend adding 5 cm on each side, 10 cm in total. Without this margin, when you look at the window from the side you can see part of the glass or frame you wanted to cover, and more light gets in at the sides.
WITHOUT OVERLAP

WITH OVERLAP

Choose this option if the blind needs to fit a specific space. Mark on the wall or ceiling where you want the outer edges of the two brackets to be, then measure from one mark to the other: this is the total width. We deduct the space taken up by the brackets, so the fabric will be about 5 cm narrower than the total width.
Here are some typical cases where it's better to measure from the brackets.
The window is in a recess, between two walls or in a corner: the blind, brackets included, needs to fit in.
A wardrobe, a shelf, a vertical radiator or a wall a few centimetres away limit how far the brackets can go.
On a wide glazed area the customer splits the total space between two or more blinds, so they work with the finished width of each one.
The blind needs to finish in line with a pelmet, a beam, a suspended ceiling or another blind in the same room.
The customer removes an old blind and wants the new one to take up the same space, perhaps using the same holes.
The customer wants to cover the wall from one side to the other, not just the window.
SO, WHAT DO YOU NEED TO DO?
If you know how wide you want the fabric to be:
If you know how wide the blind needs to be, brackets included:
Measure every window separately, even when they look the same. With just a few millimetres' difference, a blind made to another window's measurements can turn out too narrow or too wide.
⚠ WARNING
Remember to choose the right option in the configurator.
STEP 4
Find the point where you'll fix the bracket, on the wall or ceiling, and measure from there to where you want the fabric to reach: the bottom edge of the windowsill, or the floor if you want a fuller look.
Fixing point (top) → where you want the blind to reach (bottom) = height to enter
You don't need to add or subtract anything: the measurement you take is the one we make. The height ranges from 30 to 300 cm, bottom bar included. If the blind reaches the floor, subtract 1 cm so the fabric doesn't drag on the floor.


If you want a manual blind, also measure the height from the floor
Measure from the floor to the point where you'll fix the bracket. For safety reasons the chain must end at least 150 cm off the floor and is at least 50 cm long: that's why a manual blind can only be fitted from 200 cm upwards. Below 200 cm you can only choose a motorised blind.
SO, WHAT DO YOU NEED TO DO?
Measure from the fixing point to where you want the fabric to reach.
STEP 5
At this point you have everything you need:
Open the configurator, enter your measurements and choose the fabric. If you're unsure about the fabric, read the guide before configuring: you can order physical fabric samples. For any questions about measurements, there's a free video consultation.
Don't order with a measurement you're unsure of.
The blind is made to measure: write to us first, and our team will check the measurements with you before it goes into production.
SPECIAL CASES

Measure as you would for a window, taking the same constraints into account. The blind usually reaches the floor: measure from the fixing point to the floor and subtract at least 1 cm, so the fabric stays just off the floor and doesn't drag.
Side-by-side blinds make it easier to open a French door
For doors with several panels we recommend one blind per panel: you can raise just the one you walk through and leave the others down.
The maximum finished width, brackets included, is 280 cm. For a wider glazed area you need two or more side-by-side blinds.
How do you measure in this case?
For side-by-side blinds with adjoining brackets
Bear in mind there will be a gap of about 5 cm between the two fabrics.


Tips from the Centro Stile Maanta
Fix all the brackets at the same height and on the same plane, and give every blind the same height: this gives the glazed area a continuous line at the top and bottom.
If the glazed area has a mullion, place the split there: the gap sits in front of the mullion and doesn't let light through. If the mullion isn't in the middle of the glazed area, the blinds will have different widths: measure each one from its fixing point to the centre of the mullion.
TOPIC (ADD ONE FOR EACH SECTION OF THE GUIDE)
We make every blind to measure, with an overall width from 60 to 280 cm, plates included, and a height from 30 to 300 cm, bottom bar included.
No. Our indoor roller blinds are fixed to the wall above the window or to the ceiling.
Enter the fabric width if you know how wide you want it: measure the glass or frame and add 5 cm on each side. Enter the overall width if the blind has to fit a specific space, for example a niche, between two walls or next to a piece of furniture.
That way the fabric also covers the edges of the window, less light comes in at the sides, and when you look at the window from an angle, you don't see the glass or frame: it's an aesthetic recommendation from Centro Stile Maanta, our in-house style office in Italy.
No. We make the exact height you give us: if you add extra, the fabric will hang lower than you wanted. Only if the blind reaches the floor, subtract 1 cm so the fabric doesn't drag on the floor.
With the blind raised, the plate and bottom bar take up 10.5 cm of height. That's the space you need above the window to open it without hitting the blind, whether you fit it to the wall or the ceiling.
With wall fitting, about 8 cm. If the sill, handle or radiator sticks out further, choose ceiling fitting.
Yes, if you fit the plate at least 200 cm off the floor. For safety reasons, the chain must end at least 150 cm above the floor. Below 200 cm, you can only choose the motorised blind.
Yes, a manual blind can be motorised even after purchase.
No, measure each window separately. Even a few millimetres' difference can make a blind too narrow or too wide.
Use two or more blinds side by side. Measure the overall width, decide how much space to leave between the plates and divide the measurement by the number of blinds. You'll find all the steps in the “Special cases” section.
Yes, even with the plates butted together, there's about 5 cm with Kyma and about 4.3 cm with Recta. If the glazed wall has a mullion, put the split there: the gap ends up in front of the mullion.
