How to find pure space between objects?

Hello All,

I have a question about finding pure spacing between elements.

When I press the alt key and hover in the second element, I can see the padding between the elements. But if I have a line-height for text, it does not calculate where text has been started.

Actually, I need to find the exact height of the orange color in the attached screenshot.

I know drawing shape is a solution, but I'm looking for another way.

Thank you in advance.
