What is measured?
Not just one width and height, but multiple measuring points, diagonals, depth, window-frame projections and the clearance needed for the panels. Handles, vents, opening windows and windowsills are marked on the plan.
Why the person measuring should understand installation
A measurement can be mathematically correct but impractical if a panel opens into a tap, wall or piece of furniture. The survey translates everyday use into production data.
Special shapes
For curved and sloping lines, angles and reference points are recorded for a technical drawing.
Short answer
The essentials at a glance
Why millimetre precision matters for made-to-measure shutters. The right solution comes from combining the actual window and living situation with the materials, measurements and everyday use.
Practical: Use photos and approximate measurements for an initial orientation, but have every window professionally assessed before confirming the installation.
The choices that make the difference
Four points to assess before requesting a quotation
Window type
Dimensions, shape, handles and opening direction form the technical foundation.
Room
Privacy, light, moisture and the interior guide the choice of material and layout.
Appearance
Colour, louvre size and panel layout make the shutters part of the interior.
Use
Panels and louvres must remain practical and accessible for everyday use.
Avoid disappointment
Common mistakes when buying shutters
- Making a decision based on a product photo alone
- Overlooking how the window functions
- Treating made-to-measure shutters as a standard product
From idea to installation
How a carefully managed made-to-measure process works
- Collect photos and approximate measurements of the windows.
- Compare material, colour, louvre size and operation.
- Have every window professionally measured at multiple points.
- Confirm the panel layout, technical details, price and schedule.
- Have your shutters installed, adjusted and explained to you.

Frequently asked questions
Is the same solution suitable for every window or room?
No. Why millimetre precision matters for made-to-measure shutters. The window type, measurements, installation position, material load and everyday use are assessed for each situation.
What does DeVo check during the professional site survey?
We take measurements at multiple points and check the frame, reveal, handles, opening direction, windowsill, available panel clearance, and the desired louvre and panel configuration, among other details.
How do louvre size and panel configuration affect the result?
They determine how many lines you see, how open the view through is and how practically the panels can open. The proportions in relation to the window matter more than one standard size.
Can I compare materials, colours and operating options first?
Yes. During your consultation and in the Oud-Turnhout showroom, you can compare current collections, colour samples, louvre sizes and operating options side by side.
Are measuring and installation included in the process?
Yes. DeVo guides the project from advice and technical measuring through to made-to-measure production, installation, adjustment and guidance on use and care.
