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 (frerejones.com)

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.

The anti-aliasing there indicates the O and Q are the full pixel in height and the F, T are a half pixel in height.
