How this size fits
The narrow width leaves breathing room for side lighting while the additional height accommodates users of different heights and visually raises the room.
24 × 40 mirror guide
A 24-by-40-inch rectangle creates a taller, slimmer reflection suited to narrow vanities, dressing areas and walls where vertical emphasis is useful.
Nominal mirror dimensions shown. A custom frame increases the finished outside size unless specified otherwise.
Made to the stated size
Centennial Glass can fabricate the mirror to these exact dimensions, finish the exposed edges, add safety backing where appropriate, complete it with a selected wood or metal frame, and arrange professional installation. Practical material, access and mounting requirements are confirmed before fabrication.

The narrow width leaves breathing room for side lighting while the additional height accommodates users of different heights and visually raises the room.
Most installations use this size vertically. A 40″ W × 24″ H orientation can work above a low vanity or console when vertical space is restricted.
For a frameless mirror, 24″ wide × 40″ high can describe the glass itself. With a custom frame, confirm whether those measurements refer to the mirror opening or the completed outside dimensions.
Account for the vanity, faucet, backsplash, lighting, switches, outlets, trim and available mounting surface—not only the open wall width.
Exact dimensions, multiple finishes
The same 24 × 40 mirror can take on a very different character depending on its edge treatment, frame profile, finish and mounting details.
