My crochet bunny came out about 14 inches/35.5 cm tall and the base is about 7 inches/17.78 cm across. The ears are about 5 inches/12.7 cm long.

I used exactly one skein (with 7 inches to spare!) of the suggested yarn to make mine, but you can easily adjust the size for the amount of yarn you have or the size you want to make.

You could also try this one with smaller yarn to make a smaller bunny if you want.
