| Nominal cabinet width |
600 mm |
24 in |
24 in equals 609.6 mm, so the U.S. module is nominally 9.6 mm wider. |
Confirm the actual cabinet width, including fillers, end panels, doors, and hinges. |
| Common base-cabinet width range |
Often planned in 300 mm increments, such as 300, 600, and 900 mm. |
Often planned in 3 in or 6 in increments, with 12, 18, 24, 30, and 36 in examples. |
Metric and inch-based systems do not align perfectly at every size. |
Use the cabinet manufacturer’s installation drawing rather than nominal labels alone. |
| Typical base-cabinet depth |
Approximately 560 mm cabinet depth, commonly used with a deeper worktop. |
Approximately 24 in overall counter depth; cabinet-box depth is commonly less than the finished counter depth. |
Finished depth depends on the cabinet box, door or drawer front, handles, worktop, and wall clearance. |
Measure from the wall to the front face and include handles when checking walkways. |
| Typical worktop depth |
Often around 600–650 mm, depending on the cabinet and worktop system. |
Often around 25–26 in for a standard counter, depending on the overhang and cabinet construction. |
Worktop depth is not the same as cabinet-box depth. |
Allow for the front overhang, rear service void, backsplash, and wall irregularities. |
| Wall-cabinet depth |
Commonly about 300–350 mm for standard wall storage. |
Commonly about 12–15 in, depending on the cabinet type and installation location. |
Deeper wall units increase capacity but may reduce head clearance and visual openness. |
Check door swing, appliance clearance, and the user’s reach range before selecting depth. |
| Base-cabinet working height |
Frequently planned around 860–920 mm, including legs, cabinet, and worktop. |
Frequently planned around 34½–36 in, including the cabinet, toe-kick, and counter. |
There is no single universal height; user ergonomics and appliance requirements affect the final dimension. |
Measure the user’s preferred work height and verify compatibility with ovens, dishwashers, and sinks. |
| Toe-kick or plinth zone |
Often approximately 100–150 mm high, depending on the furniture system. |
Often approximately 4–5½ in high, depending on the cabinet design. |
The toe-kick reduces usable lower storage but provides foot space and protects cabinet fronts. |
Do not place pull-out baskets or drawer hardware in the toe-kick zone unless specifically designed for it. |
| Drawer-box planning |
Drawer widths should be selected to suit the 600 mm cabinet module and the available internal opening. |
Drawer widths should be selected to suit the 24 in cabinet module and the available internal opening. |
Internal drawer width is reduced by side panels, runners, front thickness, and required installation gaps. |
Measure the clear internal width, depth, and height—not only the external cabinet size. |
| Pull-out pantry width |
Typical narrow options may use approximately 150–300 mm nominal cabinet widths. |
Typical narrow options may use approximately 6–12 in nominal cabinet widths. |
Usable storage width is smaller than the nominal cabinet width because of runners and side construction. |
Check the minimum opening width, maximum load, door attachment method, and full-extension requirement. |
| Corner-cabinet planning |
Corner solutions may require standardized metric widths and a specified door or access opening. |
Corner solutions may require inch-based cabinet widths and a specified door or access opening. |
Blind corners can waste space if the adjacent cabinet and door clearances are not coordinated. |
Record both wall lengths, corner squareness, adjacent cabinet widths, and the location of services. |
| Waste-sorting storage |
Choose bin modules by the available clear internal width and depth rather than the 600 mm nominal size. |
Choose bin modules by the available clear internal width and depth rather than the 24 in nominal size. |
Bin capacity is normally stated in litres or U.S. gallons; 1 U.S. gallon equals approximately 3.785 litres. |
Measure the bin footprint, lid movement, ventilation space, and door or drawer load rating. |
| Clearance beside appliances |
Allowances vary by appliance and installation instructions; a filler may be needed beside doors or handles. |
Allowances vary by appliance and installation instructions; a filler may be needed beside doors or handles. |
Cabinet modules alone do not determine appliance clearance. |
Follow the appliance installation manual for ventilation, door swing, heat, water, and electrical clearances. |
| Wall and floor tolerance |
Uneven walls and floors may require scribing, leveling legs, or filler panels around metric modules. |
Uneven walls and floors may require scribing, shimming, or filler panels around inch-based modules. |
Nominal dimensions describe the planning grid, not the exact finished opening. |
Measure width at floor, worktop, and wall-cabinet levels; record the smallest usable dimension. |
| Recommended order of measurement |
1. Room envelope; 2. services; 3. cabinet modules; 4. fillers; 5. storage accessories. |
1. Room envelope; 2. services; 3. cabinet modules; 4. fillers; 5. storage accessories. |
A consistent sequence reduces errors when combining metric and inch-based products. |
Keep a dimensioned plan with units clearly marked as millimetres or inches. |
| Best practice for mixed-market sourcing |
Use a metric cabinet schedule and specify all accessory dimensions in millimetres. |
Use an inch-based cabinet schedule and specify all accessory dimensions in inches, with metric equivalents where needed. |
Do not assume a 600 mm accessory will fit a 24 in cabinet: the nominal difference is 9.6 mm. |
Request a dimensional drawing and verify clear opening, fixing points, load rating, and installation gaps before purchase. |
