Measure each opening independently

Record every bay or bow section at multiple widths and heights, plus the angles between sections, mullions, jamb depth, trim, handles, sill, seat, and any difference from one segment to the next.

Choose separate frames or shared posts

Individual frames can isolate uneven openings. Shared corner posts or angle strips can create continuous sightlines but require accurate included angles and enough room for panels and louvers to move.

Control how panels fold

Panels must clear neighboring panels, the bay seat, handles, plants, furniture, curtains, and each other. Unequal sections may need different panel counts to keep widths and movement workable.

Align the visible lines

Louver sizes, divider rails, frame profiles, panel seams, and finishes should read as one composition from the room even though the manufacturing dimensions remain unique to each section.

Turn the guide into a complete opening schedule.

Keep every finished width and height, mounting surface, jamb depth, panel arrangement, material, finish, hardware part, photo, and delivery note connected to the same opening ID.

Questions about this topic

Can bay-window shutters use one continuous frame?

Sometimes, but the corner angles, mullions, depth, sill, panel movement, and product system must support it. Individual framed openings may be more forgiving when the bay is irregular.
