What is the 0.8 femur tibia ratio that people say in the forum?

Is that another measure?

It means that ideally tibia should be about 80% of the length of femur, give or take 2-3 percents. If femur is 40cm than tibia is about 32 cm. Once you will measure correctly you will see that you are with in the acceptable normal range i.e., tibia is between 78%-82% of the femur length is very standard. IMO after lengthening, for the sake of functionality and aesthetics, at most tibia length should be with in 70-90% of the femur length.

exactly!

It's a ratio calculation: tibia / femur = 0.8  means tibia = 0.8 * femur, so tibia = 80% of femur
On the other way: femur / tibia = 1.2 means femur = 1.2 * tibia, so femur = 120% of tibia

It's the same same equation resolved differently.

Thanks. I understand.

0.8 and 1.2 different values but femur and tibia ratio calculation is the same.

I made a simple ratio calculation excel file.

I hope there are no mistakes

I do not know this
This is only medically to calculate the lower and upper bone proportions.
