I think I remember seeing 4x6 (3x5) on the C64, possibly in an environment like GEOS. That’s about the limit of what is usable, pixelation-wise.
Edit: The smaller GEOS UI font indeed had a cap height of 5 pixels, but it was variable-width: https://upload.wikimedia.org/wikipedia/en/e/e2/GeOS_Commodor... (the font of the icon labels)
Tasword 2 (word processor) on the Spectrum did 4x8 (3x7 with a spacer) to get 64 characters per line which was miraculous at the time.
(They probably kept it on an 8-high grid because the Spectrum's screen layout was a bit bonkers if you went off 8-alignment.)
