I also saw some posts that were talking about how short OP is without his "legs" on. Saw one that said OP was under 5 feet without them on. This is not true. Although OP himself seems unsure of how tall he is without them on. During testimony he said he was 5 foot something without them on. I think it is important to remember that his legs are amputated well below the knee. The post about him not being able to urinate without his "legs" on, while cute, is simply not true. I believe his height with his legs on is at least 6 feet.
MOO
In trying to figure out the bathroom-window-figure-passing issue, I checked Oscar Pistorius' heights
According to some reports (there is variance):
Pistoruis with his prosthetic legs is 155/6cm = 5'1" or 5' (or 5.11+/- foot)
This determined that his height while wearing the prosthetic limbs is 1.84 metres, compared with 1.55 metres on his stumps. His height-to-shoulder level is 1.56 metres with the prostheses and 1.23 metres without. His height to elbow level is 1.26 metres with the prostheses and 0.96 metres without.
