Question

Why does cabinet size matter?

The cabinet size has to divide into the wall outline, so the elevation decides the cabinet before the price does.

The outline sets the grid

A wall is a grid of cabinets. If the cabinet does not divide into the opening, the edge is filled with cut cabinets or the wall grows beyond the drawing.

One module, several cabinets

Where a family shares one module across cabinet sizes, a wall can be built from more than one cabinet size without a second module line, and spares stay common.

What to send

Send the opening in millimetres and the direction the wall is serviced from. The cabinet layout comes back with the module count.
