Wall Tilt Angle (Plumb) Calculator

Calculator

Large screens: 3 columns. Smaller: 2. Mobile: 1.

Inputs accept decimals and commas.

Units

All entered lengths use the selected unit.

Wall height (H)

Vertical height from base reference to top.

Deviation from plumb (D)

Horizontal offset at the measured point.

Measurement length (L) (optional)

Use if deviation is measured below full height.

Direction label (optional)

Adds context to reports; no effect on math.

Max tilt angle (°) (optional)

Set a limit to get PASS/FAIL.

Max deviation rate (mm/m) (optional)

Compares against computed mm per meter.

Max measured offset (optional)

Uses your selected unit (same as D).

This calculator treats the wall as a right triangle where the vertical leg is the measurement length L, and the horizontal leg is the deviation D.

Select your unit and enter the wall height H.
Measure the horizontal deviation D from a plumb line or laser.
If you measured below full height, enter the measurement length L; otherwise leave it blank.
Optional: enter tolerances (max angle, mm/m, or offset) to get a PASS/FAIL check.
Press Calculate. Use the download buttons in the result area for reports.

Sample cases for typical wall checks (illustrative only).

Wall height (mm)	Deviation (mm)	Angle (deg)	Deviation rate (mm/m)	Plumb ratio (1 in N)
3000	6	0.1146	2.0000	1 in 500
3200	12	0.2149	3.7500	1 in 266.67
4500	20	0.2546	4.4444	1 in 225

Tip: A quick field rule is mm/m ≈ deviation divided by height in meters.
