A kangaroo joey weighs about 0.5 grams at birth.
There is no other stage between joey and adult kangaroo.
Newborn kangaroos weigh just a gram or two. They are the size of a bean. Once they get older, it depends entirely upon which species of kangaroo is meant. A six month old musky rat kangaroo, the smallest of all the kangaroos, will only weigh a few grams. A six month old red kangaroo, the largest of the kangaroos, will still only weigh just under a kilogram. For a photo of a four-month old red kangaroo joey, click on the link.
