I need paint bigger and smaller fonts based on "default" font. So how
to get real "default" font size multiplatform and multi DPI.

Default Font.Size and Font.Height is 0. So how to get real size and
work with it.

Here you go:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i FBaseHeight
:= abs(GetFontData(Font.Reference.Handle).Height);

Thanks Lainz! I was also looking for fonts. This is useful stuff.

thanks lainz. Full code for Font.Size:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
RealFontSize := Round((- GetFontData(b.Font.Handle).Height * 72 /
b.Font.PixelsPerInch))
Tested only on Windows 10 with different scale and with multimonitor
DPI (Font.Size is allways same). Font.Height is changing to real
pixels.

Update: Lol now I see "bug" in my code, forgot Font.Reference.Handle
from your code and code works. What's difference?
