I think you will find, for the most part, that responsiveness rarely relates to height.
Elements don’t tend to change their heights to any great extent. If you wanted some text below a responsive image, I would use pixels rather than % or ems…much easier to understand.
If they need adjusting re viewport widths then media queries are your friend….which was the OP’s first conclusion. :)
I made this (http://codepen.io/wootfox/pen/LHohF) to help explain how I determine when to use px vs % for paddings/margins. (Have a look at the details for the description).

> because the padding/margin value is related to the font-size
Why not use em then? It works equally well with `box-sizing: border-box`. Didn’t read the rest of this thread but I think sometimes padding/margin in percentages makes sense, for example if you like some room to breath on big screens, but don’t want to waste too much pixels on small screens.
@CrocoDillon EM is relative to the font-size of the website, in extensive applications or large sites with lots of data its best to stray away from using EM’s. The document relative height will change according to the page being loaded therefore everything would carry an inconsistent feel. Sure you could avoid away from this early in the beginning but then every other person supporting must use the same mindset as you and if you haven’t already figured this out, very rarely do people do anything just like you would. Stick with media queries and % for fluid layouts.
I was referring to the Pen of the previous comment, where he mentions padding and margin related to font-size. That’s what ems are for, px is not related to font-size.
Sure in a team you have to be consistent with existing conventions, but working alone you have the luxury of always using best practices and I think you should.
