Wall penetration for oven - dimensions

Hello everyone,

what inner diameter must the wall duct for a stove have if its exhaust diameter is 150 mm.
Is that then also 150 mm or do you calculate more?

Currently just a planning question for a sketch.

Thanks.

That should normally be indicated next to the oven specifications.. secondly, the material of the wall where the pipe passes through also plays a role

I have looked, there is nothing written there.
Only that the connection on the oven is 150mm.

As I said, it is only about a drawing.
