Yea you should probably stay within 5CM, if you care about proportions.

Edit Post

You have a difficult t/f ratio to do just one LL. You will need to do two if you want to lengthen 5cm.

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).


How are the legs measured for this ratio? Searched online and got multiple different answers

Edit Post

he say 0.52 than ratio is most likely ¨Hip height¨ / total height

(length from greater trochanter landmark to the floor /  total height)

PS: please correct me if wrong

Edit Post

Leg-to-body ratio means total leg length (measured tibia bone length + measured femur bone length on x-rays) divided by total body height from head to toe.

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?
If you have plenty of money go for internal femurs.
If not, go for external tibias. Simple as that.
Everything else about proportions etc are plain bs. If you stick to 7cm on femurs or 6 on tibias you won't look bad no matter what are your exact initial proportions.
If you do huge amounts like 10cm on femurs then you'll look weird again no matter what were your initial proportions.

Edit Post

agree with you, some people ask such a weird questions that don't make sense in general.
New guys, listen this dude if you need a good advice, he know what he is talking about

7 cm on femurs will look terrible. Most guys have longer femurs than tibia and even 5 cm lengthening on femurs will produce weird disproportion between lower and upper legs. I've seen nked results of femur-only lengthening cases and above 5 cm looks terrible in most cases.

Most results people post are with clothes on so it skews the perception of how they really look post lengthening. Believe me, you won't like your body after 3 inches of femur lengthening.

If you want to gain 5 cm and don't plan doing another LL, go for tibia only. If the goal is more than 5 cm, then you have to do double LL no matter you want it or not. If you can't afford double LL, then either don't do LL at all or do only external tibia up to 2 inches only.

And, most femur LL patients who did more than 2 inches do the tibia in the end too or wish they had the funds to do it because of severe disproportion and biomechanics issues that arises after 3 inches of femur LL.

Your wingspan is pretty short.
I was 1.71 m, with 1.78 wingspan, so I got a good final proportion after 12 cm gain.
Just look to your picture in swimsuit and watch which part looks short and do it. Some people has too long femur, others too long tibia... so just look at yourself.
Be carefully, femur should be always longer than tibia !

Yeah, I too think that above 2 inches of wingspan is the limit to look acceptable, but up to 3 inches can be done if more height is needed. More than 3 inches and it will look retarded IMO.
