Short answer
34 to 36 inches suits most general standing work, putting the surface just below your relaxed wrist. Close or seated precision work wants 38 to 42; heavy work where you push down wants 30 to 32. To find your own number: stand relaxed, measure floor to wrist crease, subtract two to three inches.

Why the three numbers differ

It is about where your force comes from and where your eyes need to be.

Working heights by task. These are ergonomic ranges rather than manufacturer specifications, and they scale with your own height.

WorkHeightWhy
Heavy — planing, breaking bolts, hammering30–32″Low enough to get your bodyweight over the work instead of pressing with your arms
General — assembly, sawing, fettling34–36″Forearms roughly level; the position you can hold for an hour without noticing
Precision — soldering, small parts, seated38–42″Brings the work near your eyes without rounding your back over it

The failure of a bench that is too low is your back. The failure of a bench that is too high is your shoulders, and it is the one people notice later because it does not hurt immediately — it just makes an hour of work feel like two.

Finding your own number

The ranges above are for an average-height adult. If you are notably taller or shorter, scale them:

  1. Stand up straight with your arms hanging relaxed at your sides.
  2. Have someone measure from the floor to your wrist crease.
  3. Subtract 2 to 3 inches. That is your general-purpose bench height.
  4. Add 4 to 6 inches for precision work; subtract 4 for heavy work.

Two things that change the answer

A thick top raises the surface. If you are building a bench, the 1.5 inch top sits on top of the frame — so the frame has to be built 1.5 inches lower than your target working height. This is the single commonest mistake in DIY bench building and it is not fixable afterwards without cutting the legs.

A vise changes what “the work surface” means. If most of your work happens in a vise rather than on the top, the height that matters is the top of the vise jaws, not the bench. That is typically 3 to 4 inches above the bench surface, so the bench itself wants to be correspondingly lower.

When adjustable is worth paying for

If you genuinely do two or three of the jobs in the table above, an adjustable bench earns its price — the Seville UltraHD covers 28.5 to 42 inches in 1 inch increments, which spans the entire range.

If you do one kind of work, buy a fixed bench at the right height and put the money into storage instead. An adjustable bench that never gets adjusted is an expensive fixed bench.

Questions

Common questions

What height should a garage workbench be?

34 to 36 inches for general standing work, which puts the surface just below your relaxed wrist. 38 to 42 inches for close or seated precision work, and 30 to 32 inches for heavy work where you need bodyweight over the job.

How do I work out my own workbench height?

Stand relaxed with your arms at your sides, measure from the floor to your wrist crease, and subtract two to three inches. Add four to six for precision work, subtract four for heavy work. Then test it with a stack of offcuts before committing.

Is 36 inches too high for a workbench?

Not for general work if you are around average height — 36 is the top of the standard range. It is too high for heavy work where you want to push down, and it may be too high if you are shorter than average. Measure to your wrist rather than using a default.

Does the workbench top thickness affect the height?

Yes, and it is the commonest mistake in DIY bench building. The top sits on the frame, so a 1.5 inch top means the frame must be built 1.5 inches below your target working height. It is not fixable afterwards without cutting the legs.
