Beyond the headline number
Baseboards, trim, bowed walls, and appliance sides can make the opening narrower at the floor, middle, or top.
A rolling cart needs enough front or side clearance to leave the gap and enough handle room for everyday use.
Tall slim units need correct assembly, load distribution, leveling, and any specified restraint. Avoid placing heavy items high.
Dimension questions
Use the product's exact exterior width and leave a working margin for wheels, handles, wall variation, and pulling it out.
Check internal shelf or drawer dimensions. Narrow outside width can leave much less usable interior space.
Follow the model instructions. Stability depends on design, height, loading, and how the unit is used.
