I don't know the ideal weight range of dwarf hybrids but mine weighs 67g.
Weigh a mug or container then weigh it with the hamster in it, within a secure play pen, box etc in case he jumps out and the difference is the hamster's weight.
Dwarf hybrids tend to look chunky and round and like their food.
I feed mine daily about a heaped teaspoonful and scatter feed most of his food because he enjoys foraging for it. Best avoid fruit and carrots because they can be prone to diabetes. Aside from his hamster mix i feed fresh greens like cucumber, spinach, broccoli etc and mealworms, linseeds, pumkin seeds etc for treats.
