Area is only the starting point
Width and height influence material use, but two openings with the same area can require different panel counts, frame parts, rails, louvers, hinges, tracks, cutouts, templates, or support. That is why a single square-foot price cannot describe every shutter.
Material and finish change the work
Paint-grade and stain-grade woods, composites, fiberglass, structural PVC, vinyl, and aluminum are priced differently. Factory paint, custom color matching, stain, primer, dark-color limitations, and field finishing also change the scope.
Shapes and operation add decisions
Arches, rakes, circles, bay windows, doors, bypass tracks, movable louvers, operable exterior hardware, Bahama arms, cutouts, and nonstandard rail layouts require more engineering or fabrication than a fixed rectangular panel.
Treat freight and installation separately
Packaging depends on panel size, weight, finish protection, quantity, and destination. Installation depends on substrate, access, height, electrical or code work, removal, repair, and local labor. A useful quote shows those scopes instead of hiding them inside the product amount.
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.

Can custom shutters be priced from width times height?
Not reliably. Area may be one input, but panel count, material, finish, frames, hardware, shape, packaging, freight, and installation must also be known.
