I'm new to typography and I have been reading and learning as I go the best I can. However, I'm stumped on how to determine the proper line-height to use.
I guess what I'm looking for is the mathematical formula that is used to determine the proper line-height based on the font-size and or line-width.
I have seen NUMBEROUS typographic scale websites were you plug in the font-size and it gives you the correct line-height to use. I'm not looking for those sites so PLEASE DON'T POST THEM, I have already seen them.
I just want to learn what mathematical formula is used to determine proper Line-Height based on the Font-Size used and don't want to rely on a website to give me that information (that is not how I can learn).
I plan on building a responsive website and I need to know line-height for body, p, h1-h6 tags. I know that at different breakpoints I may need to adjust the font-size and line-height and that is what I'm looking for. The mathematical formula to use to determine the proper font-size and line-height.
