Wondering how to measure for plantation shutters before updating your windows? A few basic measurements can help you understand your space and prepare for a consultation. At Modern Group, we offer made to measure shutters designed around your windows. You can take initial measurements yourself, while our team checks the final fit before manufacturing.
To measure for plantation shutters, use a steel tape measure and record dimensions in millimetres. Measure the opening width at the top, middle and bottom, then the height at the left, centre and right. Check recess depth, handles and space for panels to open. Confirm the mounting style and fitting allowances before ordering.

For a standard rectangular window, start with these simple checks:
Use the same measurement points throughout and keep your tape straight. Our window measuring guide explains these basic checks. Knowing how to measure for plantation shutters is useful for planning, but an opening measurement is not automatically the finished shutter size. Frame dimensions and fitting allowances still need to be confirmed.
Before deciding how to measure for plantation shutters, understand where the frame will sit.

An inside mount can leave decorative window trim visible. A face fit may suit a shallower recess, but it still needs enough space around the window. When learning how to measure windows for shutters, avoid adding a standard overlap to every opening. The appropriate dimensions depend on the selected frame.

There is no universal minimum depth for all plantation shutters. The required clearance depends on the frame, louvre size and anything projecting into the opening.
When asking how much room do you need for shutters, consider three things:
A shutter can fit the opening but still hit a tap, bedside table or window handle when operated. Our plantation shutter measuring guidance explains why depth requirements vary by frame.
Understanding how to measure for plantation shutters means looking beyond a single width and height. Avoid measuring only the glass, rounding measurements to centimetres or assuming two similar windows are identical. Keep every reading, and tell your measurer about any planned tiling, new trim or window replacement.
Do not make your own deductions unless instructed for the selected product. Made to measure shutters need the correct allowances, and these should be agreed before the order is finalised. For uneven, bay or shaped windows, arrange a professional assessment rather than adapting a basic rectangular measurement.
Learning how to measure windows for shutters gives you a starting point. A professional visit also considers the frame position, panel layout and how you will reach the window. For example, you might want panels to open away from furniture or keep a frequently used handle easy to access.
At Modern Group, our installation process includes an in home consultation and measure, followed by custom manufacturing and fitting. This helps us plan made to measure shutters around both the opening and the way you use the room.

Yes. Initial width, height and depth measurements are useful for planning. Before ordering, have the dimensions, mounting position and allowances checked for the specific shutter system.
It depends on the frame and louvres. A face fit may be an option, but handles, surrounding trim and panel opening space still need checking.
Keep all three widths and heights. For many inside mount systems, the smallest readings are the starting point, but follow the supplier’s instructions. Do not average the dimensions or assume the same approach applies to a face fit.
Early measurements are useful for planning. Final measurements should reflect the finished opening, particularly if tiles, plaster, trim or windows are changing.
