Ok, answer is quite simple. Current string rendering on athens does not support kerning. Because it is not cairo's job. Kerning should be took into account *after* creating glyphs with cairo but *before* extent measurement and obviously rendering. It can be done with FreeType. I made small refactoring of text measurement and added kerning support. So, *in the latest version of Athens-Cairo* you can get extents easily: extents := CairoFontMetricsProvider new
font: StandardFonts defaultFont; extentsOf: 'Ta ffl'.
extent is an instance of CairoTextExtents. Rendering on athens with Times New Roman size 200 gives: (Mac OSX Yosemite) [image: Inline image 1] And here is what I get in Keynote with the same font [image: Inline image 2] Close enough :D Cheers, Alex On Wed, Nov 4, 2015 at 2:04 PM, Aliaksei Syrel <alex.syrel@gmail.com> wrote:

Free type source sans pro in Pharo just *does not* support kerning.
