TV height calculator & mount height planner
Find the right TV height before you drill. Calculate TV center height, bottom edge, top edge, viewing angle, clearance conflicts, and bracket-planning notes in one clean wall diagram.
TV size is measured diagonally from corner to corner.
65 in · 165 cmMeasure from the floor to your eyes in your normal watching position.
42 in · 107 cmMeasure from your eyes or main seat to the wall where the TV will be mounted.
108 in · 274 cmThis calculator estimates viewing comfort and planning heights. It does not replace your TV manual, mount instructions, stud verification, fireplace clearances, or local building/electrical requirements.
What the result means
The recommended center height is the main target because viewing comfort depends on your line of sight to the screen. The bottom and top edge heights help you compare TV height from floor, check furniture clearance, and avoid surprises with large TVs or steep viewing angles.
Important caution
VESA holes and wall plates vary by TV and mount. Treat bracket outputs as planning estimates only, then use the TV bracket height and VESA placement guide and confirm stud locations before drilling.
Method
The calculator starts with eye height, TV size, and viewing distance, then adjusts for posture, room setup, tilt, and any obstruction below the TV. For the full formula logic, see how we calculate mounting height.
TV diagonal and aspect ratio are converted into physical width and height, which is why the TV mounting height by size guide is useful for quick checks.
Eye height, distance, and posture angle define the comfortable target line. The TV viewing distance and angle guide explains why closer seats make high TVs feel worse.
Furniture, soundbars, mantels, fireplaces, and ceiling limits can force the TV higher. Check clearance above furniture and above-fireplace TV height before committing.
The result includes comfort warnings, tilt notes, and a wall-elevation diagram. Use it with the bracket/VESA guide and outlet-height guide before drilling.
Planning guides
After you calculate the center height, use these supporting guides to check room type, floor measurements, viewing distance, clearance, bracket placement, outlets, studs, and mount type.
FAQ
For a standard seated living-room setup, a good starting point is to place the center of the TV near seated eye height. The calculator adjusts this using your TV size, eye height, viewing distance, posture, and furniture or fireplace clearance.
It estimates screen dimensions from TV size, combines eye height and viewing distance to find a comfortable center-height target, then checks bottom-edge clearance, top-edge height, and viewing-angle tradeoffs. Read the full calculator methodology for the assumptions and formulas.
Use the screen center height as the main comfort target because viewing angle is based on your line of sight to the screen. Use the bottom edge and top edge heights as practical wall-marking references.
TV size changes the screen height, bottom edge, and top edge. The ideal center height may stay near eye level, but larger TVs need more clearance planning because the top and bottom edges move farther from the center.
Viewing distance changes the vertical viewing angle. The same TV height feels steeper when you sit closer and less steep when you sit farther away, but distance does not fix a TV that is far too high.
No. Treat bracket notes as planning estimates only. Actual drill marks depend on your TV, VESA hole position, mount model, wall plate, stud locations, and the manufacturer template.
Above-fireplace mounting often pushes the TV higher than the ideal comfort zone. Check viewing angle, mantel clearance, fireplace heat guidance, and whether a tilt or pull-down mount is appropriate before committing.
