Electric Fireplace Size Under a TV: Best Width Guide
How big should an electric fireplace be under a TV?
A reliable rule of thumb is to choose an electric fireplace (or fireplace TV stand) that’s slightly wider than your TV. In most living rooms, that means a unit that’s about 2–6 inches wider than the TV on each side (roughly 70–90% of the TV’s diagonal width when converted to overall screen width). This keeps the setup balanced, helps the TV feel visually “anchored,” and avoids the top-heavy look of a wide screen perched on a narrow base.
Match the fireplace width to the TV width (not the TV size number)
TVs are marketed by diagonal inches, but what matters for furniture is the TV’s actual width. For example, many 65-inch TVs are around 57 inches wide, while many 75-inch TVs are around 66 inches wide (exact dimensions vary by model and bezel). As a general sizing guide:
If your TV is 55–65 inches, a 60–70 inch fireplace can look proportionate. If your TV is 70–80 inches, a 70–80+ inch fireplace is often a better visual fit—especially if you want extra surface space for décor or sound equipment.
Consider the room scale and what sits next to the unit
In a larger room, a wider fireplace helps fill wall space and prevents the TV wall from looking undersized. If you’re flanking the setup with bookcases, speakers, or accent chairs, you can lean slightly narrower because the surrounding pieces add visual “weight.” If the fireplace is a standalone focal point on an open wall, go wider for a more intentional built-in look.
Plan for mounting height, clearance, and media components
If the TV is wall-mounted above the fireplace, confirm you’ll have comfortable viewing height and enough clearance between the mantel/top and the bottom of the TV. Also measure for soundbars and center speakers—many look best when the fireplace top is wide enough to keep the audio gear centered under the screen without overhang.
For a practical example of how a wider unit pairs with big screens, see this guide on a 72-inch mantel electric fireplace TV stand that fits TVs up to 80 inches.
FAQ
What size TV fits on a 72-inch electric fireplace TV stand?
Many 72-inch fireplace TV stands are designed to accommodate TVs up to about 80 inches, depending on the TV’s base width and whether the TV is center-mounted or uses wide-set feet. Always compare the stand’s usable top width to your TV’s actual width (or the distance between its feet).
