How are integrated dishwasher’s dimensions measured

dishwasher

Sounds like a dumb question so please bear with me.

I have an old integrated dishwasher in my kitchen, bought by the previous owners of the property which I'm planning to replace. Its width measures 58.5cm and there is only a couple of millimetres gap either side within the kitchen units. I believe it's a whirlpool diplomat, but I don't know the model number without taking the door off or pulling it out from the units.

All the dishwashers I can find to buy are at least 59.5cm width. So I'm wondering:

a) do I have a very odd shaped dishwasher?
b) have dishwashers become wider the last few years?
c) are the stated dimensions not the true width? (doubtful unfortunately)

I don't want to order a new dishwasher only to find it won't fit in my kitchen without modifying the units.

Does anyone have an idea about this?

Except for industrial and "true" commercial machines, all dishwashers are meant to go in a 24 inch (60.96 cm) wide opening, so they are usually a little smaller than that.

A quick glance at LG's site shows them all to be 23.75 inches wide by 33 5/8" high by 24 5/8" deep.
