I know there are 4 recommended font sizes in Metro UI. (9, 11, 20 and 42 points)
Guidelines and checklist for text and typography
But it didn't mention this rule applies which pixel density and screen resolution .
I recently read an article about Metro UI scaling to different screens from
here and realized there are 3 scale percentages in Win 8.
They are:
100% (when no scaling is applied)
140% (for HD tablets)
180% (for quad-XGA tablets)
Could anyone advise me what's the rule for font size in different screen resolutions?
Thank you.
