Today I Learned that letters with round tops (Q, O, S, etc.) are drawn a smidgeon higher than letters with flat tops (E,T,F, etc.). This 'overshoot' makes them appear equal to our perception
That title doesn't seem true. I zoomed in on the text above and took a screenshot, then zoomed in even more on that screenshot and edited in some marker lines:
Maybe some fonts do that, but not the default one used on Lemmy. Nor, I suspect, most common web sans serif fonts.
The smaller the font the less noticable, especially with pixelation. But look at the top red line you drew, the F & T are grey pixels and the Q & O are white in the center.
Typography, and design as a whole are such enjoyable things to experience. Even sometimes, when being sold to. But on the whole, I have found I would rather a frightful design and more freedom (and less data snatching), than being up-sold some "fancy" looking thing that's some Bauhaus trash.
That was some sloppy I should be asleep trash. This is an interesting article though, I especially like the part where they show how weight can affect the design of individual characters.
