How to use Typography Converter

Set the DPI, then type a value in any unit field. The tool converts everything through pixels to update pt, em, rem, mm and cm.

Frequently asked questions

How many pixels is 12pt?

At 96 DPI, 12pt equals 16px using px = pt × DPI / 72.

Why does DPI matter?

Point-to-pixel conversion depends on resolution; changing DPI rescales every point and metric result.

How are em and rem computed?

Both use a 16px root by default, so 1em = 1rem = 16px unless your root font-size differs.
