Summoning Jutsu's

Giant Ice Wolf:Makes a large ice wolf bid on listening to master(summoner) and do whatever they wanted

Ritikiti The Boom Monkey: Summons a knee high Monkey with an unlimited amount of bombs built for sabotage or making very well hidden traps

Toji: A mis formed creature which turns into almost anything but comes at a cost, the summoner gets a terrible disease that can only be made from unique items in every village

i would say any summoning you do that is giant it uses half your chakra and medium a quarter and small half of a quarter

well wolf is big

ritkiti is small

and toji is kindof medium to small

(depends on what figure you make him)
