Cure for the Common Webfont, Part 2: Alternatives to Georgia
december 2010 by cloudseer
For nearly fifteen years, if you wanted to set a paragraph of web text in a serif typeface, the only truly readable option was Georgia. But now, in web type’s infancy, we’re starting to see some valid alternatives for the king of screen serifs. What follows is a list of serif typefaces that have been tuned—and in some cases drawn from scratch—for the screen.

Using the WebFont Loader to Make Browsers Behave the Same
december 2010 by cloudseer
Web fonts give us designers a whole new typographic palette with which to work. However, browsers handle the loading of web fonts in different ways, and this can lead to inconsistent user experiences.
Safari, Chrome and Internet Explorer leave a blank space in place of the styled text while the web font is loading. Opera and Firefox show text with the default font which switches over when the web font has loaded, resulting in the so-called Flash of Unstyled Text (aka FOUT). Some people prefer Safari’s approach as it eliminates FOUT, others think the Firefox way is more appropriate as content can be read whilst fonts download. Whatever your preference, the WebFont Loader can make all browsers behave the same way.
The WebFont Loader is a JavaScript library that gives you extra control over font loading. It was co-developed by Google and Typekit, and released as open source. The WebFont Loader works with most web font services as well as with self-hosted fonts.
The WebFont Loader tells you when the following events happen as a browser downloads web fonts (or loads them from cache):
when fonts start to download (‘loading’)
when fonts finish loading (‘active’)
if fonts fail to load (‘inactive’)
If your web page requires more than one font, the WebFont Loader will trigger events for individual fonts, and for all the fonts as a whole. This means you can find out when any single font has loaded, and when all the fonts have loaded (or failed to do so).
The WebFont Loader notifies you of these events in two ways: by applying special CSS classes when each event happens; and by firing JavaScript events. For our purposes, we’ll be using just the CSS classes.
Implementing the WebFont Loader
As stated above, the WebFont Loader works with most web font services as well as with self-hosted fonts.
Self-hosted fonts
To use the WebFont Loader when you are hosting the font files on your own server, paste the following code into your web page:
<script type="text/javascript">
WebFontConfig = {
custom: { families: ['Font Family Name', 'Another Font Family'],
urls: [ 'http://yourwebsite.com/styles.css' ] }
};
(function() {
var wf = document.createElement('script');
wf.src = ('https:' == document.location.protocol ? 'https' : 'http') + '://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js';
wf.type = 'text/javascript';
wf.async = 'true';
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(wf, s);
})();
</script>
Replace Font Family Name and Another Font Family with a comma-separated list of the font families you want to check against, and replace http://yourwebsite.com/styles.css with the URL of the style sheet where your @font-face rules reside.
Fontdeck
Assuming you have added some fonts to a website project in Fontdeck, use the afore-mentioned code for self-hosted solutions and replace http://yourwebsite.com/styles.css with the URL of the <link> tag in your Fontdeck website settings page. It will look something like http://f.fontdeck.com/s/css/xxxx/domain/nnnn.css.
Typekit
Typekit’s JavaScript-based implementation incorporates the WebFont Loader events by default, so you won’t need to include any WebFont Loader code.
Making all browsers behave like Safari
To make Firefox and Opera work in the same way as WebKit browsers (Safari, Chrome, etc.) and Internet Explorer, and thus minimise FOUT, you need to hide the text while the fonts are loading.
While fonts are loading, the WebFont Loader adds a class of wf-loading to the <html> element. Once the fonts have loaded, the wf-loading class is removed and replaced with a class of wf-active (or wf-inactive if all of the fonts failed to load). This means you can style elements on the page while the fonts are loading and then style them differently when the fonts have finished loading.
So, let’s say the text you need to hide while fonts are loading is contained in all paragraphs and top-level headings. By writing the following style rule into your CSS, you can hide the text while the fonts are loading:
.wf-loading h1, .wf-loading p {
visibility:hidden;
}
Because the wf-loading class is removed once the the fonts have loaded, the visibility:hidden rule will stop being applied, and the text revealed. You can see this in action on this simple example page.
That works nicely across the board, but the situation is slightly more complicated. WebKit doesn’t wait for all fonts to load before displaying text: it displays text elements as soon as the relevant font is loaded.
To emulate WebKit more accurately, we need to know when individual fonts have loaded, and apply styles accordingly. Fortunately, as mentioned earlier, the WebFont Loader has events for individual fonts too.
When a specific font is loading, a class of the form wf-fontfamilyname-n4-loading is applied. Assuming headings and paragraphs are styled in different fonts, we can make our CSS more specific as follows:
.wf-fontfamilyname-n4-loading h1,
.wf-anotherfontfamily-n4-loading p {
visibility:hidden;
}
Note that the font family name is transformed to lower case, with all spaces removed. The n4 is a shorthand for the weight and style of the font family. In most circumstances you’ll use n4 but refer to the WebFont Loader documentation for exceptions.
You can see it in action on this Safari example page (you’ll probably need to disable your cache to see any change occur).
Making all browsers behave like Firefox
To make WebKit browsers and Internet Explorer work like Firefox and Opera, you need to explicitly show text while the fonts are loading. In order to make this happen, you need to specify a font family which is not a web font while the fonts load, like this:
.wf-fontfamilyname-n4-loading h1 {
font-family: 'arial narrow', sans-serif;
}
.wf-anotherfontfamily-n4-loading p {
font-family: arial, sans-serif;
}
You can see this in action on the Firefox example page (again you’ll probably need to disable your cache to see any change occur).
And there’s more
That’s just the start of what can be done with the WebFont Loader. More areas to explore would be tweaking font sizes to reduce the impact of reflowing text and to better cater for very narrow fonts. By using the JavaScript events much more can be achieved too, such as fading in text as the fonts load.

Web type news: iPhone and iPad now support TrueType font embedding. This is huge.
november 2010 by cloudseer
TrueType font embedding has come to iPhone and iPad, Hallelujah, brothers and sisters. That is to say, Mobile Safari now supports CSS embedding of lower-bandwidth, higher-quality, more ubiquitous TrueType fonts. This is huge. Test on your device(s), then read and rejoice:
The Typekit Blog: iOS 4.2 improves support for web fonts
iOS 4.2 is also the first version of Mobile Safari to support native web fonts (in TrueType format) instead of SVG. This is also exciting news, as TrueType fonts are superior to SVG fonts in two very important ways: the files sizes are dramatically smaller (an especially important factor on mobile devices), and the rendering quality is much higher.
Ryan N.: Confirmed: TrueType Font Support on Mobile Safari on iOS 4.2
Thanks to Matt Wiebe for mentioning the rumour that Mobile Safari on iOS 4.2 supports TrueType fonts and providing a handy link to test.
TrueType
TrueType is an outline font standard originally developed by Apple Computer in the late 1980s as a competitor to Adobe’s Type 1 fonts used in PostScript. TrueType has become the most common format for fonts on both the Mac OS and Microsoft Windows operating systems.
The primary strength of TrueType was originally that it offered font developers a high degree of control over precisely how their fonts are displayed, right down to particular pixels, at various font sizes. With widely varying rendering technologies in use today, pixel-level control is no longer certain in a TrueType font.
More about webfonts
If you’re coming late to the party, the following bits of required reading and listening will get you up to speed on the joys (and occasional frustrations) of “real type” on the web:

60+ Free WordPress Themes
february 2010 by cloudseer
Via instantshift.com
Pulling the trigger just got easier. Now anyone can have a beautifully designed, standards-compliant WordPress site. The 60-plus recently created free WordPress themes (AKA template collections) listed by InstantShift’s Daniel Adams are categorized by function and style: “Clean and Minimal,” “Artistic and Fancy,” “Magazine Style,” “Portfolio Style,” “News and Social Media Style,” “Showcase and Galleries Style,” “E-Comerce and Shopping Cart Style,” “Domain Parking/Coming Soon Style,” and “Other.” Something for everyone.
Not everything here is a winner or will appeal to every taste, but there is plenty of great work to be had here. If WordPress is your CMS (it’s mine), even if you are a designer, you may ask yourself if you really need to perform that next site redesign from scratch.

Designing For The Switch
december 2009 by cloudseer
For a long time on the web, we’ve been typographically spoilt. Yes, you heard me correctly. Think about it: our computers come with web fonts already installed; fonts that have been designed specifically to work well online and at small size; and fonts that we can be sure other people have too.
Yes, we’ve been spoilt. We don’t need to think about using Verdana, Arial, Georgia or Cambria.
Yet, for a long time now, designers have felt we needed more. We want to choose whatever typeface we feel necessary for our designs. We did bad things along the way in pursuit of this goal such as images for text. Smart people dreamt up tools to help us such as sIFR, or Cufón. Only fairly recently, @font-face is supported in most browsers. The floodgates are opening. It really is the dawn of a new typographic era on the web. And we must tread carefully.
The New Typesetters
Many years ago, before the advent of desktop publishing, if you wanted words set in a particular typeface, you had to go to a Typesetter. A Typesetter, or Compositor, as they were sometimes called, was a person whose job it was to take the written word (in the form of a document or manuscript) and ‘set’ the type in the desired typeface. The designer would chose what typeface they wanted – and all the ligatures, underlines, italics and whatnot – and then scribble all over the manuscript so the typesetter could set the correct type.
Then along came Desktop Publishing and every Tom, Dick and Harry could choose type on their computer and an entire link in the typographic chain was removed within just a few years. Well, that’s progress I guess. That was until six months ago when Typesetting was reborn on the web in the guise of a font service: Typekit.
Typekit – and services like Typekit such as Typotheque, Kernest and the upcoming Fontdeck – are typesetting services for the web. You supply them with your content, in the form of a webpage, and they provide you with some JavaScript to render that webpage in the typeface you’ve specified simply by adding the font name in your CSS file.
Thanks to services like these, font foundries are now talking to create licensing structures to allow us to embed fonts into our web pages legally – which has always been a sticking point in the past. So, finally, us designers can get what we want: whatever typeface we want on the web.
Yes, but… there are hurdles. One of which is the subject of this article.
The differences between Web Fonts and other fonts
Web fonts are different to normal fonts. They differ in a whole bunch of ways, from loose letter spacing to larger x-heights. But perhaps the most notable practical difference is file size. Let’s take a look at one of Typekit’s latest additions from the FontFont library, Meta.
Meta Roman weighs in at 42 KB. This is a fairly typical file size for a single weight of a good font. Now, let’s have a look at Verdana. Verdana is 186 KB. For one weight. The four weight family for Verdana weighs in at 686 KB. Four weights for half a megabyte!? Why so huge?
Well, Verdana has a lot of information packed into its 186 KB. It has the largest hinting data table of any typeface (the information carried by a font that tells it how to align itself to the pixels on your screen). As it has been shipped with Microsoft products since 1996, it has had time to grow to support many, many languages. Along with its cousin, Georgia (283 KB), Verdana was a new breed of typeface. And it’s grown fat.
If really serious web typography takes off – and by that I mean typefaces specifically designed for the screen – then we’re going to see more fonts increase in file size as the font files include more data. So, if you’re embedding a font weighing in at 100 KB, what happens?
The Flash of Unstyled Text
We all remember the Flash of Unstyled Content bug on Internet Explorer, right? That annoying bug that caused a momentary flash of unstyled HTML page. Well, the same thing can happen with embedding fonts using @font-face. An effect called The Flash of Unstyled Text (FOUT), first coined by Paul Irish. Personally, I prefer to call it the Flash of UnTypeset Text (still FOUT), as the text is styled, just not with what you want.
If you embed a typeface in your CSS, then the browser will download that typeface. Typically, browsers differ in the way they handle this procedure.
Firefox and Opera will render the text using the next font in your font stack until the first (embedded) font is loaded. It will then switch to the embedded font.
Webkit takes the approach that you asked for that font so it will wait until it’s completely loaded before showing it you.
In Opera and Firefox, you get a FOUT. In Webkit, you don’t. You wait.
Hang on there. Didn’t I say that good web fonts weigh in considerably more than ‘normal’ fonts? And whilst the browser is downloading the font, the user gets what to look at? Some pictures, background colours and whatever else isn’t HTML? I believe Webkit’s handling of font embedding – as deliberate as it is – is damaging to the practice of font embedding. Why? Well, we can design to a switch in typeface (as jarring as that is for the user), but we can’t design to blank space.
Let’s have a closer look at how we can design to FOUT.
More considered font stacks
We all know that font stacks in CSS are there for when a user doesn’t have a font; the browser will jump to the next one in the stack. Adding embedded fonts into the font stack means that because of FOUT (in gecko and Opera), the user can see a switch, and depending on their connection that switch could happen well into any reading that the user may be doing.
The practicalities of this are that a user could be reading and be towards the end of a line when the paragraph they are reading changes shape. The word they were digesting suddenly changes to three lines down. It’s the online equivalent of someone turning the page for you when you least expect it. So, how can we think about our font stacks slightly differently so we can minimise the switch?
Two years ago, Richard Rutter wrote on this very site about increasing our font stacks. By increasing the font stacks (by using his handy matrix) we can begin to experiment with different typefaces. However, when we embed a typeface, we must look very carefully at the typefaces in the font stack and the relationship between them. Because, previously, the user would not see a switch from one typeface to another, they’d just get either one or the other. Not both. With FOUT, the user sees two typefaces.
By carefully looking at the characteristics of the typefaces you choose, you can minimise the typographic ‘distance’ between the type down the stack. In doing so, you minimise the jarring effect of the switch.
Let’s take a look at an example of how to go about this.
Micro Typography to build better font stacks
Let’s say I want to use a recent edition to Typekit – Meta Serif Book – as my embedded font. My font stack would start like this:
font-family: 'Meta Serif Bold';
Where do you go from here? Well, first, familiarise yourself with Richard’s Font Matrix so you get an idea of what fonts are available for different people. Then start by looking closely at the characters of the embedded font and then compare them to different fonts from the matrix.
When I do this, I’m looking to match type characteristics such as x-height, contrast (the thickness and thinness of strokes), the stress (the angle of contrast) and the shape of the serifs (if the typeface has any).
Using just these simple comparative metrics means you can get to a ‘best fit’ reasonably quickly. And remember, you’re not after an ideal match. You’re after a match that means the switch is less painful for the reader, but also a typeface that carries similar characteristics so your design doesn’t change too much.
Building upon my choice of embedded font, I can quickly build up a stack by comparing letters.
This then creates my ‘best fit’ stack.
This translates to the CSS as:
font-family: 'Meta Serif Bold', 'Lucida Bright', Cambria, Georgia, serif
Following this process, and ending up with considered font stacks, means that we can design to the Flash of UnTypeset Content and ensure that our readers don’t get a diminished experience.

Well, we can design to a switch in typeface (as jarring as that is for the user), but we can’t design to blank space.
Let’s have a closer look at how we can design to FOUT.
More considered font stacks
We all know that font stacks in CSS are there for when a user doesn’t have a font; the browser will jump to the next one in the stack. Adding embedded fonts into the font stack means that because of FOUT (in gecko and Opera), the user can see a switch, and depending on their connection that switch could happen well into any reading that the user may be doing.
The practicalities of this are that a user could be reading and be towards the end of a line when the paragraph they are reading changes shape. The word they were digesting suddenly changes to three lines down. It’s the online equivalent of someone turning the page for you when you least expect it. So, how can we think about our font stacks slightly differently so we can minimise the switch?
Two years ago, Richard Rutter wrote on this very site about increasing our font stacks. By increasing the font stacks (by using his handy matrix) we can begin to experiment with different typefaces. However, when we embed a typeface, we must look very carefully at the typefaces in the font stack and the relationship between them. Because, previously, the user would not see a switch from one typeface to another, they’d just get either one or the other. Not both. With FOUT, the user sees two typefaces.
By carefully looking at the characteristics of the typefaces you choose, you can minimise the typographic ‘distance’ between the type down the stack. In doing so, you minimise the jarring effect of the switch.
Let’s take a look at an example of how to go about this.
Micro Typography to build better font stacks
Let’s say I want to use a recent edition to Typekit – Meta Serif Book – as my embedded font. My font stack would start like this:
font-family: 'Meta Serif Bold';
Where do you go from here? Well, first, familiarise yourself with Richard’s Font Matrix so you get an idea of what fonts are available for different people. Then start by looking closely at the characters of the embedded font and then compare them to different fonts from the matrix.
When I do this, I’m looking to match type characteristics such as x-height, contrast (the thickness and thinness of strokes), the stress (the angle of contrast) and the shape of the serifs (if the typeface has any).
Using just these simple comparative metrics means you can get to a ‘best fit’ reasonably quickly. And remember, you’re not after an ideal match. You’re after a match that means the switch is less painful for the reader, but also a typeface that carries similar characteristics so your design doesn’t change too much.
Building upon my choice of embedded font, I can quickly build up a stack by comparing letters.
This then creates my ‘best fit’ stack.
This translates to the CSS as:
font-family: 'Meta Serif Bold', 'Lucida Bright', Cambria, Georgia, serif
Following this process, and ending up with considered font stacks, means that we can design to the Flash of UnTypeset Content and ensure that our readers don’t get a diminished experience.
