minicar: I want to get a mini so i can train my friend to ride she is about 45 lbs. and she is about 3'4-6 height do you think a mini will work or is she to heavy?How much weight can a mini horse carry?Minis can so be ridden. Horses, including minis, can carry up to 20% of their body weight, that including tack. I wouldrecomend a slighty bigger pony for your friend maybe 11hh.How much weight can a mini horse carry?Minis cannot be ridden at all. They can be driven though to a very small, light weight trap.How much weight can a mini horse carry?minis as in fanabella cant be ridden, but mini as in shetland can and will carry that weight no problem if made they can carry 10 stone, 140lbs. but most i'd put on the be 6 stone. so that would be fine, but smallest you could use will be a shetland. good luck|||Miniatures can usually carry one third to one half of their own body weight (they can pull twice their weight) but it depends on what type of miniature it is and how fit it is. I think your friend will be better off with a small pony 11 to 12 hands.
