Rabbit size/weight

I currently have a 'dwarf' lop but I am not so sure this is the case. He looks quite large to me. Can anyone tell me what his size roughly should be if he is a dwarf? Also what is the best weight for rabbits, I don't want him getting fat so want to check on things like that.

Dwarf Lops should weigh a max of 5lb 4oz - well thats the max show weight so a pet rabbit i'd expect to be aorund that mark.

German lops are the next sze up and weigh 8 1/2lbs. Is he that big?

many people buy dwarf bunnies thinking they will say small the dwarf lop is considered a dwarf to the much larger french lop but not to the nethyerland dwarf or polish - these are the smallest breeds of rabbit, dwarf lops are about average weight 2.4kg while the smaller mini lop (in uk) is about 1.8kg but neutered bunnies tend to weigh alittle more
