I am a 170cm male.

I am a 170cm male.

My femur is 45 cm long and my tibia is 35 cm long.

Wingspan is 170cm.

I want to be about 5~6cm taller.

Do you think I should lengthen the tibia or the femur?

penis is better 

Where are you from? If you are not like -2sd of the average height of your country this surgery is not that worthy. If you are average then just forget about this surgery. I don't recommend those whose heights do not impact thoroughly negatively on their lives.

The average height of men in my country is around 174~175cm.

I agree with the others.

Your femurs are already pretty long relative to your tibia so you should probably go with tibia if you must.

Given that your wingspan is already the same as your height, you could probably get away with 3-4cm but by the time you're 175/5'9, you're at a 5cm wingspan deficit at just 175. I think it probably starts to get noticeable after that. Not sure though. Maybe others who've done it can chime in.

According to most people in the proportion section, up to 7 cm above your wingspan is acceptable and not really that noticeable.

I honestly think it depends on your build and torso size as well. The smaller and thinner you are to begin with, the less you can lengthen without it looking off. Again this is just what I have observed, since this matter is subjective.

How do you measure your tibia and femur? If it was not with traditional xray or dexa scan it is very difficult to be accurate, btw tibia:femur ratio is usually .8 +-.02

I'm ~168 with a 175 wingspan. Are you saying that I can get away with heightening to 180cm without my 5cm wingspan deficit being noticeable?

Your arms will look shorter the more you lengthen, there's no question about it. Unless your arm length is ridiculously long for your natural height, you won't look normal past 4 inches of LL. And, most guys have normal arm length for their natural height, therefore, they must be aware that they won't look natural after significant lengthening of legs.

IMO, measure your leg-to-body ratio and try not to exceed 0.52 post-LL. That's the highest I'd go with (only if I was really short like 5'2 and needed to max out on 2 LL procedures). Otherwise, any guy starting from 5'5 who wants to get double LL for 2 main reasons: 1. height gain and 2. boosting proportions between rather short legs and long torso should calculate his arm length, leg length, torso length and lengthen within the safe limits. Anything past 2 inches per segment will look bad and requires another LL to fix the proportions.

So, if the need is more than 2 inches, double LL is necessary at this point. IMO, 4 cm in tibia and 5 cm in femur is enough and won't look bad unless having ridiculously long legs and short torso (with short arms) before LL. 9 cm is enough height gain if one is at least 165 cm of height.
