Short answer

Garage base cabinets are typically 18 to 24 inches deep and around 72 to 77 inches tall in full-height sets. Wall cabinets run 12 to 18 inches deep. Worktops sit at 34 to 36 inches, with about 18 inches of clearance to the wall cabinet above.

Published dimensions from actual sets

These are the figures two manufacturers publish for real products, rather than generic category numbers — useful because they show what a full wall actually consumes.

Published assembled dimensions read from manufacturer product pages on 2 September 2026.

Set	Width	Depth	Height
NewAge Bold Series, 8-piece	180″	18″	76.75″
NewAge Bold XL, 7-piece	108″	24″	76.75″
Gladiator Large GearBox	36″	18″	72″
Gladiator Modular GearBox (wall)	28″	18″	31″

Note the Bold Series eight-piece set at 180 inches — fifteen feet. That is most of a garage wall, and it is the number people do not picture when they look at a photograph of a set.

The depth decision, and the car door

6inches

The difference between an 18 inch and a 24 inch cabinet run. Across a side wall in a single-car garage, that is frequently the difference between opening a car door fully and not. It is the single most common regret in this category.

Eighteen inches suits hand tools, paint, consumables and boxed items. Twenty-four inches is what a miter saw, a compressor or a shop vac needs to have the door close.

Before choosing, do this: measure your car’s width, add the door swing, and compare against the garage width minus the cabinet depth. Then tape the footprint on the floor and open the door inside it. Ten minutes, and it settles the question permanently.

Heights and clearances

Working dimensions for laying out a wall. General practice rather than manufacturer specifications, except where noted above.

Element	Typical	Why
Worktop height	34–36″	Standing work height — see the height guide
Worktop to wall cabinet	~18″	Keeps the surface usable and the cabinet reachable
Wall cabinet bottom, no worktop	~54″	Puts the lower shelf at chest height
Full-height cabinet	72–77″	Top shelf reachable without a step, for most people
Wall cabinet depth	12–18″	Shallower than base, so you do not hit your head leaning over the worktop
Base cabinet width	24–36″	The module most runs are built from

Measuring your wall properly

Measure the wall at floor level and at cabinet-top height. Garage walls are frequently not parallel, and a run that fits at the bottom may not at the top.
Note every obstruction. Electrical panel, outlets, light switches, hose bib, water heater, the garage door track and its spring. Each one is a place a cabinet cannot go.
Mark the door swing. Both car doors, fully open, plus the path a person walks past them.
Check the floor slope. Garage floors fall toward the door. A full-height cabinet run will need shimming, and you want to know that before delivery day.
Measure the route in. Door widths, turns, steps. Welded cabinets do not fold.

With these numbers you can sketch the whole wall on paper in five minutes, which is the point — the layout guide at garage wall layout covers what goes where once you know what fits.

Questions

Common questions

What is the standard garage cabinet depth?

Eighteen inches is the category standard, with premium ranges offering 24 inches. NewAge publishes 18 inches for Bold Series and 24 for Bold XL; Gladiator publishes 18 inches. Eighteen suits hand tools and consumables; 24 is what power tools need.

How tall are garage cabinets?

Full-height sets run 72 to 77 inches. NewAge publishes 76.75 inches for both its Bold and Bold XL sets; Gladiator publishes 72 inches for the Large GearBox. Wall cabinets are much shorter — Gladiator’s Modular GearBox is 31 inches.

How much wall does a garage cabinet set take up?

More than the photographs suggest. NewAge’s eight-piece Bold Series set is published at 180 inches wide — fifteen feet, which is most of a typical garage wall. Measure your wall against the set’s published overall width before ordering.

How high should a garage worktop be?

34 to 36 inches, the same as a general-purpose standing work height, with about 18 inches of clearance to any wall cabinet above so the surface stays usable and the cabinet stays reachable.
