I think the crewniverse said that part of the height of a fusion depends on what they fuse for. I think the other part might be based on the components themselves, for instance Stevonnie is more human then Gem so they only have their components combined mass. Rainbow likely only uses Rose's and Pearl's mass, Smoky is about the same as Stevonnie.
