This does not look like Verdana. 

Not sure if it's relevant to the size issue, but are you sure some other
font is not being served in lieu of Verdana?

I don't know, it looks like verdana to me, but the main point is that a
9pt and 11pt they display as expected and there are no differences
between the two browsers.  Also, the same problem at 10pt happens with
other fonts.

Quoting Camaleón:
 - What are your fonts settings in Iceweasel?
 
 Here is what I have:
 
 ***
 Occidental (iso-8859-1)
 Proportional font: San serif
 Serif: Times News Roman / point: 16
 Sans-serif: Arial
 Monospace: Courier-new / point: 13
 Smallest font size: none
 [x] Allow pages to select their own font face, instead the above selection

Well this last line is all that's needed, style sheets will override
whatever font I pick.

 BTW, you can make some checks between Chrome and Iceweasel by browsing 
 through these pages:
 
 http://fm.no-ip.com/auth/Font/font-arial.html
 http://fm.no-ip.com/auth/Font/font-tahoma.html
 http://fm.no-ip.com/auth/Font/font-verdana.html

Thanks for the links, hadn't thought of doing that comparison, here is
what I get: http://fruple.com/kemper/font_sizes2.png

Seems like Iceweasel has some issues with font sizes, chrome's
progression is clearly more linear while iceweasel has some spikes:
7pt is much bigger than 6, while being almost equal to 8. Same thing at
9/10/11 points.

Should I file this as a bug? And against what package? Iceweasel itself
or does it have another package taking care of the font rendering?

Thanks

Yes. That option checked means the browser should display the fonts as 
defined by web pages.

This is the only way you get what the web designer wants you to get. I 
know that can be a problem for some people that want to use their own 
styles, but anyway, is just a matter of taste, has no relevance with your 
issue.

Chris Jones is right, that not seems to be a Verdana (compare your image 
with mine) but the fact is the same font (whatever font it is) is 
displayed bigger than in Chrome.

For this reason and in order to get accurate results, just keep the [x] 
Allow pages to select their own font face, instead the above checked, 
this way we can see the real Verdana font and if it renders at its right 
size.

 progression is clearly more linear while iceweasel has some spikes:

Yes, Chrome's progression is smoother than Iceweasel.
 
 Should I file this as a bug? 


I cannot reproduce it, but I only have Icewasel (3.0.6) and Epiphany 
installed and both display the same size for all fonts.

 And against what package? Iceweasel itself
 or does it have another package taking care of the font rendering?


The package should be Iceweasel, yes.

But take into account that Chrome uses Wekbit as rendering engine and 
Iceweasel uses Gecko, that is, two different engines that *may* render 
things a bit differently.

Understood.

But since I don't have a similar testing environment set up here to make
comparisons, I thought I'd mention it.

Just in case, I run: 

$ fc-match verdana
$ fc-match sans

Actually my first reaction to your initial post was thi s:

  http://www.xs4all.nl/~sbpoley/webmatters/verdana.html

But, it looks like I was barking the wrong tree since you later wrote
that this affected all .ttf's.

One other detail that I found a little odd is that you mention setting
the font to 10pt in Iceweasel since Seamonkey's Preferences dialog uses
pixels as the font size unit.

I guess I should boot into my Squeeze partition and install Iceweasel
and see if I understand this better.

Although things are likely to be different since I did a dist-upgrade on
a lenny clone rather than a fresh install.

I'm fine with verdana being that different, my only problem is that now
it's rendering differently than it used to before my last testing
update.

 the font to 10pt in Iceweasel since Seamonkey's Preferences dialog uses

Ah, well I was just using the CSS way of saying it, as in 
  
  font-size: 10pt;

since browser preferences have no effects on styled web pages (which is
where my problem comes up).

 I guess I should boot into my Squeeze partition and install Iceweasel
 and see if I understand this better.

I have verified this both on a fresh install and on another partition
after a dist-upgrade.

Anyway I'll link again the screenshot with the differences in font
rendering:

I see. Yes, it renders bigger than it should be.
 
 Iceweasel (3.5.5, but same behavior with 3.0.14) on the left, google
 chrome on the right: the usual appearence I always had is the one shown
 now in chrome. Epiphany looks the same as Iceweasel (they use the same
 engine maybe?). This is driving me crazy, any idea on what caused this?
 
 I verified it's not related to a specific profile, as it's the same on a
 new freshly created user.

Does this happens in all applications? I mean, does OOo writer renders 
verdana 10pt at the right size or also renders it a bit bigger?

Openoffice writer renders Verdana 10 just like Iceweasel (assuming its
10 point size setting is the same as CSS 10pt). So does Abiword, but I'm
not sure it's a significant comparison.

I asked because if this behavior is reproducible system-wide (that is, 
if almost any application renders Verdana 10pt a bit bigger than it 
should) it could be related to your screen dpi size.

At least under Lenny (in Gnome desktop) the default dpi was (wrongly) 
setup at 86 dpi and I had to change it to 96 so all fonts look at their 
right size. 

I'm also using TrueType fonts, mostly the MS ones (Arial, Verdana, 
Tahoma, Courier New...) and now all of them renders okay in *any* program.

But I'm not sure if the problem you are facing can be related to this at 
all :-?

That's interesting, although I guess that would be more likely if the
prolem was extended to all the fonts, not just one (or a few, I'm only
sure about the example I linked) -- anyway how can I set screen DPI?
Option in `device` section in xorg.conf seems to have no effect.

That's an important point. 

Are all the fonts rendering bigger than they should or just happens with 
Verdana? If only one font is rendering badly, it is also possible that 
the file is corrupted in some way.

OTOH, are you using TrueType (.ttf) fonts?

In Gnome, you can right-click on the desktop and select Change desktop 
background / Fonts tab / Details

In KDE, it should be under Control Center (or Systems settins, I dunno 
the KDE4 way :-P) / Appearance / Fonts.

Well, so far I found that the problem happens only with truetype fonts
and ONLY at 10pt (tried arial, verdana, tahoma, trebuchet ms) -- they
look different on the two browsers. Other font-sizes look the same.

Okay, then.

- What are your fonts settings in Iceweasel?

Here is what I have:

***
Occidental (iso-8859-1)
Proportional font: San serif
Serif: Times News Roman / point: 16
Sans-serif: Arial
Monospace: Courier-new / point: 13
Smallest font size: none
[x] Allow pages to select their own font face, instead the above selection
***

BTW, you can make some checks between Chrome and Iceweasel by browsing 
through these pages:

http://fm.no-ip.com/auth/Font/font-arial.html
http://fm.no-ip.com/auth/Font/font-tahoma.html
http://fm.no-ip.com/auth/Font/font-verdana.html

Here is a snapshot of how Iceweasel renders Arial and Verdana fonts in my 
system:

http://picpaste.com/arial.png
http://picpaste.com/verdana.png

Also, print the pages (directly from both, Chrome and Iceweasel) to see 
if you still see the size difference in the printed page.
