What is the # of em units to match a PC’s pixel? ( Not a mac’s ).

The reason I ask is that I have font which uses 1000 UPM & has 100em unit pixels ( vector not bitmap ).

This font looks nice & crisp at 10 pt - on a mac.

But it does not look crisp at any size on the PC. It has been true type hinted ( which helped alot ) but it seems quite clear - it just isn’t fitting the grid.

Any ideas?

The default resolution on Windows systems is 96dpi, but many people tweak it. Otherwise, 7.5 points should in theory render your font crisply.

In the not-too-distant future, operating systems will automatically query the resolution off the display using Extended Display Identification Data (EDID), so a “pt” will, once again, be 1/72” or thereabouts.

What if I wanted to tweak my font for PC users? What # of em Units should I use? 75em?

Testing in photoshop with a 96 dpi image rather than a 72dpi seemed to bear this idea out . :-) Yea! - I haven’t been able to test it on a pc yet. Obviously this issue is only relevant if you are looking for a match *onscreeen* - the printed fonts would not match with this soultion. Still, that is what I was looking for. Thanks!
