Common questions
Are these dimensions exact for every product?
No: they are the typical ranges each class ships in, compiled so you can shortlist by class before reading spec tables. The exact product's listed dimensions always decide the purchase.
Why do minimum cabinet widths matter?
They encode the class's real footprint plus working margin. A class listed at minimum 21 in will physically enter smaller cabinets sometimes, but it will not leave room to use it.
Which class should I check first?
Run your measurements through the fit checker; it maps your numbers to these classes automatically. This chart is the reference behind that mapping.
