Whenever I'm designing a website I usually choose my font sizes on intuition. However I would like to start using typographic scales in my designs to create more consistency throughout all pages. But I feel they're rather constraining then helping me.
For example my Home page has a lot of different headings so I use a lot of different font sizes. I have created a scale that suits this page for the most parts. But when I'm designing the Single Post page which is just one column with many paragraphs of text I like to use a font size which is off this scale.
I have tried creating a scale for my Home page and then adjust the Single page to this scale and vice versa but there are always items which are too small or too big to my taste.
So how strictly do you have to apply typographic scales in your designs? How do you use a scale which fits the needs of different kind of pages?
