How big is an electric fireplace?#
An electric fireplace ranges widely by install type, from a 23-inch insert to a 60-inch wall-mounted panel, and just 4 to 16 inches deep. The table below sorts the insert, wall-mounted, and mantel versions by width, height, and depth.
Electric fireplace dimensions by configuration#
| Configuration | Width (in) | Height (in) | Depth (in) | Best for |
|---|---|---|---|---|
| Insert electric fireplace | 23–39 | 20–28 | 8–12 | dropping into an existing firebox or mantel |
| Wall-mounted electric fireplace | 30–60 | 18–24 | 4–7 | a slim linear look on the wall |
| Mantel electric fireplace | 40–60 | 36–44 | 11–16 | a freestanding furniture-style unit |

Installation clearances for an electric fireplace#
- Overhead clearance: 6–12 in in above a wall-mounted electric fireplace to a shelf or a mounted screen, so heat does not build up.
- Recess depth: 4–12 in in of wall or firebox depth an electric fireplace needs, depending on flush or surface mount.
- Outlet: An electric fireplace plugs into a standard outlet, ideally behind the unit so no cord shows.
- Heat vent: An electric fireplace blows warm air from a front or top vent that must stay clear of drapes and furniture.
Will your electric fireplace fit? Clearances and door swing#
An electric fireplace has no door swing, so the fit game is depth and heat clearance. A slim wall-mounted panel is only 4 to 7 inches deep and hangs like a large TV, while an insert needs 8 to 12 inches to drop into an existing firebox or mantel opening. Whatever the style, leave 6 to 12 inches of clear space above a wall-mounted unit before a floating shelf or a mounted screen, because the front heat vent pushes warm air upward and heat should not pile up against anything mounted close over it. Recess depth runs 4 to 12 inches depending on whether you flush-mount or surface-mount. Each unit plugs into a standard outlet, ideally placed behind the fireplace so no cord shows, and the warm-air vent must stay clear of drapes and nearby furniture.

Electric fireplace sizes by type: insert electric fireplace, wall-mounted electric fireplace, mantel electric fireplace#
The three formats suit very different installs. The insert electric fireplace, 23 to 39 inches wide and only 8 to 12 inches deep, is made to drop into an existing masonry firebox or a mantel cabinet and convert it to electric. The wall-mounted electric fireplace is the slim linear one, 30 to 60 inches wide but just 4 to 7 inches deep, hung on the wall for a modern floating look. The mantel electric fireplace is a piece of furniture in its own right, 40 to 60 inches wide and 36 to 44 inches tall, freestanding with a built-in surround and shelf. Choose by where it lives — inside an opening, on the wall, or standing on the floor.
Electric fireplace dimensions: common questions#
How wide is an electric fireplace?#
An electric fireplace ranges from 23 inches for a small insert to 60 inches for a wide wall-mounted or mantel unit. Wall-mounted linear panels are the widest at 30 to 60 inches.
How deep is a wall-mounted electric fireplace?#
A wall-mounted electric fireplace is only 4 to 7 inches deep, so it hangs nearly flush like a flat-panel screen. That slim depth is what makes the linear wall style so popular.
What clearance does an electric fireplace need above it?#
Leave 6 to 12 inches of clear space above a wall-mounted electric fireplace before a shelf or mounted screen, so heat from the front vent does not build up against it. Keep drapes and furniture away from the warm-air outlet as well.
Can an electric fireplace drop into an existing firebox?#
Yes. An insert electric fireplace, 8 to 12 inches deep, is designed to slide into an existing masonry firebox or mantel opening and plug into a standard outlet, converting a wood or gas hearth to electric.
How tall is a mantel electric fireplace?#
A mantel electric fireplace stands 36 to 44 inches tall as a freestanding furniture piece with its own surround. It is the tallest format, versus 18 to 28 inches for wall and insert units.
