Planning limb lenghhening (problem wingspan)

Hello, I'm writing because I'm planning leg lengthening surgery in the future and I need advice. I plan to  increase my height to 167-170 cm. I'm 160 cm tall, have a 164 cm arm span, and a 78 cm inseam. I'd like to know if my proportions will be cartoonish (with T-Rex-like arms) and my legs very long after the surgery, or if they'll be proportionate and my shorter arms won't be as noticeable. I'm asking for advice and guidance on this matter. I'd be very grateful. 

honestly your numbers dont sound like t rex arms at all

you are 160 now with 164 wingspan so your arms are already a bit longer than your height which is common
if you go to 167 to 170 then your wingspan would be only a little shorter than your height and thats still totally normal lots of people are built like that and nobody notices

about legs looking too long it depends more on how much you do and which bone
if you stay conservative and dont chase the max right away you will keep a very natural look
you can always reassess later

if proportions worry you the most do a quick check before deciding
measure sitting height and take full body photos front and side
show them to your surgeon and ask for the most balanced plan

youre thinking about the right things just dont overthink it too much 🙂

Arm span is a useless measurement. What you need is your pure arm length (the length you measure from your acromion bone to the tip of your middle finger). For your height, a 70cm arm length indicates that you have an arm length proportionate to your current height. (Meanwhile, measure with your arms hanging loosely down.) If you have a 70cm arm, you don't need to worry too much about the additions you'll make; believe me, even a stranger wouldn't notice (unless you lengthen both the femur and tibia at the same time). It's recommended in the forum that the leg length/height ratio shouldn't exceed 0.51. In your case, assuming you've lengthened your femur by 8 cm, the ratio of 78+8/168 is slightly excessive. But I don't think anyone will notice; only we in this forum are concerned with people's percentages.
