Normal proportions?

Edit Post

Hello everyone I am a European guy in my mid 20s.
I would like to know a few things about the proportions and if they are normal for me. Like many here, I would like to do the operation sometime in my life.

My measurements are
Height :: 166.7cm
Wingspan :: 168cm
My tibia length: 36cm
My femur length: 41cm
My tibia-femur ratio: 0.87

What does that ratio mean? Short femurs?
Short tibias?
According to a video from Cyborg4life the normal ratio of the femur is-tibia should be 0.75

Personally I prefer not to put any photos of my physique (I hope you understand). But in general I see short legs but not a short segment in particular.

I hope you solve my doubts, thank you.

I didn't know about the X-rays. Thanks for the information. Still I think my femurs are not long because my fingertips stay about 10 cm from the knee joint. I don't know if I will be providing the truth that I don't want to look like a clown on stilts if I ever manage to raise the money to have surgery.
