Standard Cabinet Depths and Heights: Base, Wall, and Tall

Depth and height drive gable blanks, the largest rectangles on most kitchen nests. A shop that standardizes these two axes can reuse cut list templates across jobs and only customize width and interior fittings. A shop that improvises depth on every quote redraws every gable and burns yield on one-off sheet layouts.

This article focuses specifically on depths and heights for professional casework. Width modules and full kitchen grids appear in the standard kitchen dimensions guide; panel math appears in the calculation guide.

Pair with standard kitchen cabinet dimensions and the cabinet making pillar for the full size system.

If the kick is recessed into the gable, the 34.5 in height usually includes the kick zone. If the box sits on a separate platform, the platform height plus box height must still hit the counter target. Mixing methods across a single run creates uneven counter lines.

Cut list note: gable height is not optional poetry. It is the first number on the largest parts. Confirm kick method before nesting a full kitchen.

Tall pantry and oven cabinets often share base depth (24 in) so the front plane aligns. Heights of 84, 90, and 96 in match door head heights and crown packages. Ceiling height minus frieze or scribe detail sets the real maximum.

From a nesting view, tall gables are sheet killers. A 96 in gable on a 96 in sheet edge needs perfect orientation and leaves no salvage strip. Consider horizontal splits with a mid rail if your design allows, or plan grain-matched joints deliberately.

Import drawings may show 720 mm base carcases with adjustable legs to reach ~900+ mm work height, 600 mm base depths, and wall depths around 300–350 mm. Do not force these into 34.5 / 24 / 12 without checking the counter and appliance package.

Keep one unit system per cut list. Convert at the design handoff, then calculate and nest.

Changing base depth from 24 to 21 in rewrites every base gable and bottom depth, plus many stretchers and shelves. Changing wall height from 30 to 42 in lengthens every wall gable and back. Both moves can add sheets on a large kitchen even if width stays fixed.

Re-nest after any depth or height change. Estimators who only scale area percentages miss grain locks and strip waste.

Put your default depths and heights in a one-page shop standard. Train designers and estimators to call out exceptions in bold on the job ticket. The floor should never guess whether a vanity is 21 or 24 deep.

When defaults are stable, remnant strategies improve: leftover 24 in deep strips from last week's bases become this week's stretcher stock.
