What you need to know: Media wall fire depths
When planning a DIY media wall, always start with the electric fire. Electric fires are almost always deeper than TVs, and while average depths sit around 7 to 10 inches, actual depth and cavity requirements vary significantly depending on the make, model, and screen size.
Key planning tips:
Flat walls & large rooms: You have plenty of depth to play with, so standard or deep-box models work great.
Chimney breasts & smaller rooms: Opt for a slimline electric fire to save floor space. Just ensure your TV is shallow enough to match the slimline frame.
Alcoves: Remember to leave cavity depth and wiring space if you plan to add LED strip lighting.
Ventilation & clearances: Always check manufacturer guidelines for required air gaps around both the fire and TV to ensure safe heating and ventilation.
