You need to state your application, the question is too broad.
e.g. for machine tool use there is linear scales.

So how long is this piece of string!
Are we talking shrinkage? Or is it being reeled in?
Still NEI!

Put one turn around a pulley of known diameter and measure the rotation of that pulley.
