Video - Measuring your Arm Span (or Reach)

As a teenager, arms and legs can grow before your torso. It's why teens at times can seem gangly. Arm spans generally have a ratio of 1.02-1.03:1. That is, your wingspan is a bit more than your height. It can vary between race. A long reach might be a ratio of 1.06:1, a short reach 0.99:1. In this video I show how to measure your armspan easily.

I'm 195cm out of bed so I claim I'm exactly 6'4"/193cm to people, but my arm span/reach is only 190cm/almost 6'3" :(

When you measure armspan do you hold your arms out fully extended or do you hold them loose? I think I asked you this before but what is 182 or 5 ft 11.5 armspan equivalent to?
[Editor Rob: hold them out fully as much as possible and as straight out as you can.]

It was this video that drew me down the dark path that is height obsession! You may need to give me some tips on living life at 5 ft 8 my height seems to have ground to a halt for a while!
[Editor Rob: Blake, before doing this site, I didn't think about height much...in fact I created many other sites before deciding to focus on a big 'authority' site, which happened to be this one!

5ft 8 is a good inch under average in the UK, but I believe if you fill your life with interesting things and people, there's less time to worry about things like height. I know it is hard for people, they can become too obsessed with a topic.]

Do you think quite a few people have an armspan matching their height?
[Editor Rob: considering the average will be a little more than your actual height, there will be a chunk with equal height/arm ratios, some with less armspan than height and a decent chunk with greater armspans than height.]

What sort of age range with teenage boys does the armspan stop growing and the torso lengthen?
[Editor Rob: it might be 15-17 range that the torso can catch up a bit after the limbs grow at 13-15 range.]

Rob I had only just watched the video and the way you measured your armspan! I had been laying a tape measure on the ground and doing it. I used your technique and got 181cm! Also do you put shoulders and head against the wall when measuring?
[Editor Rob: yeah you could put the shoulders and head, it means you will get the fullest measurement...just make sure arms are at right angles to your body.]

Rob so with my long armspan 6 foot and a little bit is it a sign i can grow several inches before i stop growing im 15 and 2 months im now 172.5 in the middle of the day?
[Editor Rob: limbs can grow faster than the spine, or earlier, so sometimes it is an indication you may well still gain another couple of inches.]

Is it strange that my height increases roughly the same amount my armspan does will it even out. My armspan grew roughly 2cm so did my height since I last checked both. So are my legs growing at the same pace as my armspan?

I checked my arm span today couple of millimeters over 6 foot I thought arms and legs stopped earlier?

How did I end up with such a bad reach!! I am 6ft with a 5ft 9.5 wingspan.

Does your armspan increase with your height im 5 foot 7 with a 5 11.5 armspan so is that my fixed armspan im 14 and male.
[Editor Rob: the armpsan in teens can tend to be longer than height because arms/legs can grow faster and earlier than the torso. It could be a good sign you have several more inches to grow.]

Hey rob whats the armspan of a 5'11 guy
[Editor Rob: you might expect roughly 6ft, but you could have 6ft or 6ft 2-4 range for a long span]
