I made some text on my pcbs really quite small, fully expecting it to be a miserable mess, but in fact it’s beautifully sharp.
In the text sparks.gogo.co.nz shown below, the width of the lines in the characters is approx 6 mil (approx 0.15mm), this is a “Vector Font Size 4 with Normal line width” in Diptrace. The total height of the letter k is approx 46mil (approx 1.15mm). It is very clear and readable, and looks roughly the same or a bit smaller as the ID number printed by the board house.
