The most accurate way to measure clavicles?

[thebeast0503]

When people say they have X inch clavicles/bideltoids, are we measuring them with your lats and shoulders engaged/flared? or absolutely everything relaxed? (as shown in the pictures)

Relaxed/how you normally are

relaxed

most accurate = xray, obviously

biacromial != bideltoid
