Angled exterior view of a black bay window, operating casement sashes open 45 degrees, 96 by 54 inch frame with dimension lines, rendered from the Panes 3D configurator

Bay windows combine three panels at an angle to project beyond the exterior wall. The central pane provides a broad view, while the side panels create the distinctive angular appearance. The projection can form an interior alcove or window seat. Compare the panel sizes, angles, and operating side windows, and review the opening and support requirements with your installer.

Width and projection are separate measurements. Confirm final dimensions and support details with your installer.

Separate width, height and projection

The 96 × 54 inch dimensions identify the configured frame. Projection is the distance the bay extends beyond the wall; it is a separate measurement. The angle and individual section widths affect that depth. Send a top-view sketch and have your installer confirm the approved frame dimensions, projection and rough opening before ordering.

Compare the complete installed scope

Replacing an existing bay and converting a flat window opening involve different work. Ask your installer to itemize support, head and seat boards, roof or soffit work, flashing, insulation and trim. The online price covers the configured window product; it is not a complete installed-project price.
