My haffie Willy is 14.2 hands and can carry a adult or child. Many haflinger folk will say that they can carry 30% of their body weight even those with a athletic build. I love the haflinger breed but realize that although they are very cute and most have wonderful personalities they are a horse. Mine is just going on seven. He walks, trots and canters. He likes to jump and does well on the trail but I would not put a beginner rider on him unless he was being lead. I hope this answered your question and didn't go on for to long.
