Size difference between dwarf and mini lops

We have just got what we were told is a 'dwarf' lop bunny, and although I know dwarf lops are supposed to be bigger than mini lops, I was wondering if anyone knows how much bigger they should be, as she's quite a lot bigger than my minis. What weights should the 2 types be? Just wondering as we got her with lots of details unknown, and were wondering if she's the 'next size up' from a dwarf! Thanks!

My minilop is 1.8kg and my dwarf lop is 2.5kg.

I've found the description of different rabbit breeds on this website helpful:

If your "dwarf" is anything like mine it could end up HUGE - I think Grace is 5kg and she was supposed to be a "dwarf" lop but there is just more of her to cuddle
