I've been interested in arm lenght since I found out my wingspan is lower than my height fortunately it turns out my arms aren't short for my height and I think this is a good point to make. It's all well to use wingspan and weigh it to your height but what will really make your proportions off is a short pair of arms.
I found this thread on the makemetaller forum: -- -- in which the OP presents a guideline. The "normal" arm lenght is that which is at a ratio 2.3 of your height. Allegedly the proportions start to seem off at a ratio of 2.5.
This means that my arms (76CM) are average for my height (179CM) and can support an increase up to 190CM max.
Another concept I found on the same forum (although I've lost the link, sorry) is that your arms should ideally be 43-44% of your height -that is the average. This means that a 190CM man should have an arm lenght of roughly 82CM, a 180CM man -77CM and a 170CM man -73CM.
Now obviously no one is going to notice if you lack one or two centimeters in your arms but a guideline to follow (though not scientifically proven) is to not exceed the ratio of 2.5.
I thought maybe these thoughts might be of some use to you guys so I'll share it here -feel free to discuss.
Edit: Looks like the link I posted doesn't work I'm really sorry. The thread is called "Height to arm lenght reatio" if you want to look for it yourself. On the old forum -again sorry.
How did you measure your arm?
From the end of my middle finger to the top of my acromion bone,
180cm, 79cm.
Suppose I really have short arms for my height then. Damn it.
3CM isn't a noticeable difference when comparing arms. Didn't you say that you father has the same arm length as you? If this is the case, then your arms will look fine at that height. Perhaps they won't look anywhere near "long", but they won't look abnormally short either.
When all is said and done I'll see how it looks but ideally my arms should be 4 cm longer. I've read that the growth plates in arms don't fuse untl 20 years on average does anyone know if they might grow another cm?
Typically the forearms are done growing by 18, but the humerus (upper arms) tend to fuse a little later. Femurs are also among the last long bones to stop growing.
I've heard that men tend to "fill out" i.e getting broader until 21-22 is that true?
That is true, as far as I know. Men can fill out as late as 25 years of age, in some cases. Your small arm span could well be due to shoulders that are not yet at their full developed width.
