How the screen & tv mount height calculator works
The comfortable default is the screen centre at seated eye level, so the mount centre equals your eye height. The top and bottom edges are half the screen height above and below that centre. Where a screen has to sit higher — above a fireplace, say — a small down-tilt brings the picture back towards a square-on view.
What you enter
Enter the seated eye height and the screen height; the calculator returns the screen centre, top and bottom heights. Every field is editable, and the result recalculates the moment you change a value.
Reading the result
Eye-level centring is the least tiring for long viewing. If the room forces a high mount, add a few degrees of down-tilt and expect a small compromise in comfort.
Safe by design
This is pure geometry and acoustics — there is no safety threshold anyone acts on. It plans what you can see and hear, not any electrical or structural work.
Assumptions and limits
This assumes a single seated eye height and a flat wall. Mixed seating (a bar stool behind a sofa) or a reclining chair shifts eye height, and a very high mount strains the neck no matter the tilt. Measure your own seated eye height for the best result.
Using it with the rest of BuildMetricLab
This calculator is one step in planning the job. Pair it with the related tools in this category and across BuildMetricLab to go from a single figure to a full costed plan — a sizing figure feeds a cost estimate, a cost estimate feeds a project budget, and each result carries straight into the next tool. Every BuildMetricLab tool runs entirely in your browser — no sign-up, nothing sent to a server, and the formula is shown on the page so the maths can be audited.
Sources & methodology
Works out the mounting centre, top and bottom heights for a screen so its centre sits at seated eye level. Every result is calculated from the values you enter, all inputs are editable, and no time-sensitive prices or rates are embedded.
Frequently asked questions
How high should I mount a TV?
With the screen centre at seated eye level — usually around 1.0–1.2 m to centre for a sofa. This tool works it out from your own eye height.
What if the TV goes above a fireplace?
That is higher than ideal. Add a down-tilt of a few degrees and accept a small comfort compromise, or consider a pull-down mount.
Does mount height depend on screen size?
Yes — a taller screen puts its top and bottom further from the centre. The tool gives all three so you can check clearances.
What eye height should I use?
Measure your eyes above the floor when seated in the actual chair — it varies with the seat and the person.
