How do I measure the distance between two adjacent nodes in a line?

How would I minutely adjust the distance between these two nodes? My goal would be to see that the distance between two nodes might be 15.75 pixels and then I would like to tweak that up our down by fractions of a pixel for perfect fit.

Thank you!

Hello. See this post to ideally help with your situation.

See this post about moving nodes (especially Brynn's response.)

and this one, too.
