this is my first post in the forum. Let me first introduce myself. My name ist Karsten (alias PoohBear) and I have lately found this new interesting software fontforge. And it amazes me what one can do with the software, I am not into fontdesign professionally, but I am playing with the idea of creating my own stuff. I love to play with all kinds of things.

Anyway, I am not getting fontforge to kern those few letters that I have designed. I am testing those few letters "ABCDEaoge" in browsers by inserting
@font-face {
font-family: "myFont";
src: url("myFont.ttf") format('truetype');

Kerning problem


I recently spotted an issue with kerning in FL.
In metrics window all kerning works fine but when i generate "kern" feature some pairs among classes are excluded. But it is only visible in OT preview and later in exported file. What interesting is, when I change the order of the code, e.g. I bring the missing pair to the top of the code, it works. Anyway the whole thing behave very random and I can't get the logic of this. I was searching the problem but didn't found the exact answer. Putting extra "subtable" doesn't fix the problem.

Hope it sounds clear.

Any suggestions would be highly appreciated.

Kerning not working in MS Word

I have recently started making fonts in Fontlab. And every font I have generated, have had trouble with kerning in Microsoft Word. (They look good and have perfect kerning in InDesign etc.) I have seen this topic appear a lot. But unfortunately none of the solutions have helped me.

Anybody got any ideas?

anyone knows why this problem is happening with kerning Alef letter in single adjustment? when you duplicated the same letter you will get bigger space then smaller then bigger then smaller.. etc

I have set kerning in my win type 1 font, and, wanted to use it in MS word. Weird is, kerning works just in some cases - just on basic characters. The problem is only in office - in all other programs like illustrator / indesign not.

- screenshot - left - illustrator, right MS word 2007 (problem at "ře" vs "re" )

- turn kerning in word on/off,
- play with settings at fontlab options in kerning,
- made openType feature "kerning" with kerning asist.
nothing worked. seems like word ignoring all national characters kerning..

Anyone can help me?

The SVG font format has support for kerning via the hkern element. Is kerning in SVG fonts supported by any web browser?

I'm just trying to add kerning to my SVG fonts and it didn't work. I'm not sure what the source of the problem is, is it the lack of browser support or is it my font.

Any info or reference implementation would be helpful.

Thanks in advance


what is the best way to kerning in Volt? changing dx? or width? I faced a problem when I kerning "pair Adjustment"for the same letter, ex: rr (in english) or Raa Raa (in arabic) when I test it and type the letter for 5 times, it shows spaces between them. anyone faced it before?

Is it just me or is there something wrong with the type used in this journal? I'd like to send them a note, but don't know how to put it in words. The lines look irregular, both vertically and horizontally to me, but maybe it is just that the column is too narrow to do full justification at that size?

The full article is here as pdf

This FontLab tool allows to import and export kerning and classes between FontLab and MetricsMachine.

I have a trouble with the kerning pair exceptions. When I compile the font some kerning pairs exceptions (Bï, Cï, Fï) are ok, but others like Dï, Eï, Gï, Kï etc ... not recognize the exceptions. However in Fontlab seems ok and the classes for those glyps are similar.

Anyone know what could be the problem

Hi guys,

Can you please explain to me the basics of kerning and how to do that with Hebrew fonts (I've heard that its a little bit tricky...)

Problems kerning Bembo

Hi everyone, first post here.

I found typophile while looking for some infos about Bembo Std (picked up from the Adobe shop) which I'm using for a book.
First of all in the Adobe page there's the following statement:
"Bembo Std family is designed to be used at a text size of 8.0 points"
So, is it a problem if I set size to 11pt ?

I also have a little problem with kerning (I'm using InDesign).
I set "Metric" in the paragraph style (I read "Optical" is not the best choice for text ) but the result is not so good.
Especially for the "V". The kerning is automatically set to -175 with the result that there's almost no space between the "V" and previous character.

When kerning fonts with both Lining and Oldstyle proportional numerals what is the generally accepted form when it comes to kerning? Are all numbers kerned with every other glyph or is it best just to kern 0-9 with all punctuation and parenteses/brackets/braces only? Interested to hear thoughts. Thanks.

Can you guys educate me about some general rules to be followed while kerning Helvetica. And can you point out the shortcomings in terms of kerning in the piece below and suggest any improvements. It looks alright to me but you guys are better at this. I really want some help with kerning lowercase "r" and "t".

Thanks, I really appreciate the help.

Hi guys.

I'm a new member, I signed up to ask a question as I have been scouring the web for a week and couldn't find anything.

I'm an artist and was recently asked to make a font for my studio. I had never done anything like this before and other than photoshop could only use freeware. So I used photoshop to make the paths, exported to Inkscape to make the font file and then to fontforge to do the kerning and then generating as a TTF.

I have hit a few snags however and try as I may I cannot sort them out so I have come here to hopefully beg some help from people with much more experience in this area than I.

TTF Kerning

A client with a TrueType font wanted some glyphs added but were not able to contact the person who created it the font initially.

Because it uses has at least MKMK, which FontLab doesn't support, I used ttx to create a text file and through a combination of FontLab and the ttx file was able to add the glyphs they wanted.

They now want some kerning added, which I did in the ttx text file and recompiled. The new kerning works when the font is used in Word 2003 but NOT in Word 2010 or InDesign. There is SOME sort of kerning working in InDesign as I can see that the characters pairs listed in the font have kerning between them. Likewise for Word 2010, turning the kerning on and off with some text selected makes definite changes at some kerning pairs.

Hi all,

I'm currently designing my first font set in Fontographer and am having an issue when generating it.

Apologies if this has been asked numerous times, but I would appreciate the help.

I've kerned all my individual pairs to a point I'm happy with, but when I generate the font it seems that the changes aren't taking place. I'm viewing in Linotype Fontexplorer. I've also tried activating the font and testing it in Illustrator to check, and I still don't have the kerning I wanted.

Any thoughts?

I licensed a font the other day, a recently released family of 10 weights * 2 styles * text + display version. I was a bit suspicious of the whole thing, as there didn't seem to be a PDF specimen available anywhere. But the introductory offer was a nice one, and the font seemed perfect for my purposes.

What I got was a font that, as expected, does have its qualities in some respects, but is kerned so horribly that it's pretty much useless for the application it was design for -- it's meant to be a ›legible‹ sans for body text.

I have a family of fonts I'm building in FontLab. They are all using the same exact kerning data and kerning classes. For some reason, one of the fonts is giving me a "serious error" in Font Book that says there is a "System Validation" error, with no further details.

I've tried taking a .vfb file from one of the working fonts, copying over glyphs from the font that's giving me trouble, and generating again. Same error. I think I've pinpointed the problem to be something kerning/class related, as if I copy/paste glyphs that AREN'T in a class and generate the font, I don't get an error in Font Book. But once I copy glyphs that are in a kerning class, I start getting the error.

Hi All,
Just wanted to get some feedback on the problem areas (kerning-wise) on this word mark that I'm in process on for a client. (Created by heavily modifying Carisma Light ( in case anyone was curious) Any thoughts are appreciated guys, thank you,


I'm new on the forum so I introduce myself

i'm a swiss student, and I tried for my studies In ancient history to build a font.
I used fontforge and finally fontlab. Everything works perfectly except the kerning.

MS word 2010 doesen't take count of the kerning of my new font...
Kerning works perfectly on Oppen office, but I have to make it work on MS word. Is it possible ?

Somebody knows what is the problem ? Can somebody help me ?

Thanks for help :)


I am trying to generate my new font I have created, but am having serious trouble with the kerning. I have tried a plethora of different options, but nothing seems to be working. Basically, I export my font, but the kerning rarely shows up in applications. I know there is a kerning table, though, because the font works correctly in TextEdit (mac).

I am using Fontlab Studio. When I try the font in Photoshop and Microsoft Word, it does not kern. Are there any ideas as to why this would be? Thank you very much in advanced.

Flat TrueType Kerning Table Size Limits

Hello, all. Is there a way to break up the kerning table into smaller ones in plain TrueType? As far as I can tell, the issue is simply that this table is too large in my font(s). I flattened my kerning classes to pairs, removed OT data, but while TypeTool, FontForge, and InDesign all see the pairs, Word doesn't. (Yes, I do have kerning enabled in Word.) However, when I remove glyphs (I have a lot of diacritics), Word can see them just fine. So, I'm pretty sure I need to break up the table or something; how do I do this?

It's probably worth mentioning that I didn't need to insert subtable statements in the OT code for the CFF version.


I'm stumped; I'm not seeing kerning changes exported in FontLab, with I process that I *thought* had worked before. Here's what I do:

I go to Window->New Metrics Window. I change to Text Mode, and type:


I change the Metrics Window to Kerning mode, and nudge the 'o' far enough to the right it's obviously wrong. I go to Tools->Quick Test As . . .

And . . . I see no change.

Maybe someone could tell me what steps I'm missing? I have Class Kerning with exceptions, and I've also tried rebuilding the Kern feature.
