Overview
Frames and panel layouts allow shutters to suit many openings. Practical limits come from the fixing surface, available clearance, panel sizes and operation of the underlying window. Unusual shapes, severe unevenness or heavy obstructions need a closer assessment before ordering.
Inside or outside mount?
Use an inside mount where the recess provides a sound fixing surface and enough clear operating depth. Use an outside L-frame where a shallow or obstructed opening prevents that fit. Both choices need room for the panels to swing and access to the window's controls.
Z or L-frame?
Inside mounting offers Z-frame and inside L-frame options; outside mounting uses the outside L-frame. Choose around the recess, trim and sill, then check hardware in the frame, rail and louvre zones. Handles do not automatically rule out shutters, but their position must be accounted for.
Plantation shutters with window winders
Measure to the furthest point of the winder and note its height and distance from the edge. A top, bottom or midrail may align with it and need less depth than rotating blades. Where it still conflicts, assess an outside frame. Photograph the fitting from the side before asking for a recommendation.
How many panels?
Opening width and permitted panel size determine the available layouts. As a guide, an individual panel can be approximately 900 mm wide, and overall openings above about 950 mm generally need multiple panels. Double-hinged arrangements have smaller panel limits.
Fewer panels mean fewer vertical lines, but narrower panels need less swing space. Check taps, benches, furniture and walls before choosing the hinges.
