Is there a way to find out the dimensions or size of an object in ParaView?

Yes, under properties you have a tick box "Show Cube Axes", or similar. That shows the coordinate axes about an imagined bounding box of your selected object.

Works really well with parallel projection.

I can confirm, the actual name is 'Axes Grid', and it is found on the View (Render View) properties panel (along with Properties, Display and View).

Moreover, you can find the bounding box size in ParaView by selecting the data in the Pipeline Browser, and clicking 'Information' (you can turn on the 'Information' Panel from View --> Information). Here, the Bounds (delta) is the bounding box size, which will vary from dataset to dataset.

So a 128x128x128 dataset can be crammed into a 6x6x6 bounding volume, or a 32x32x32 dataset can have a bounding box the size of 32x32x32.

ParaView deals with this by computing Display.ScaleFactor, Display.GaussianRadius, Display.ScalarOpacityUnitDistance and Display.Slice variables (you can see this when you generate Python Trace and load in some dataset).
