A Comprehensive Guide to Microsoft Vista Fonts for Designers

[T]here are no bad fonts — only inappropriate ones.

Jason Beaird

The majority of computer users became aware of Microsoft Windows Vista on January 30, 2007, when the company released the new operating system publicly.

You and I of course knew about it well beforehand. Once Vista was available for beta, many web designers adopted it early to begin trying — with varying levels of success — to figure out if they can incorporate Vista fonts into their designs.

Three things quickly became clear:

  1. They are beautiful typefaces.
  2. They are unusually — and, for designers, unacceptably blurry unless you have ClearType or another anti-aliasing protocol enabled; but there are serious issues with ClearType.
  3. With some exceptions, they are markedly smaller in size than most fonts, making them difficult to incorporate into font stacks.

Trust Microsoft to create something attractive and potentially valuable like this set of spiffy new fonts (or an operating system like Vista), and then take steps to ensure they can’t be used easily.

But I like these fonts: they’re beautiful and they are available in many of our user’s computers (as much as 92% of all PCs use Windows as of May 2010[1]). In addition, the design community deserves some thought as to how to use them in their work.

Let’s see what we’re up against.

Breaking Down the Fonts

Breaking Down the FontsVista “C” fonts.

Let’s examine the fonts themselves, starting with the best known of the group: the 6 “C” fonts — their nickname derived from the fact that all their names start with the letter C, and officially, because they are part of the Microsoft ClearType font collection.

John Hudson, the font designer who made one of the C” fonts (Constantia), shares some insights on how the “C” font names were picked:

“One of the Microsoft managers had come up with the idea that all the CT [Vista] fonts should have names that started with C. I can’t remember all the possible names I came up with, each of which ended up rejected after international trademark searches. Microsoft probably spent more money on lawyers doing trademark searches than they spent on the typeface development! As I recall, the day before the penultimate choice came back rejected, I’d been singing some psalms during vespers, and noticed the word constantia. Hey, I thought, that starts with C!”

If you have Vista, Windows 7, MS Office 2007 for Windows, or MS Office 2008 for the Mac, you have these fonts already. If you don’t have them yet, keep reading!

The “C” List

Here is a bit of information about each of the “C” Vista fonts.


The new default font for MS Office apps  — replacing the tired old warhorse, Times New Roman — Calibri is a softer, more rounded sans-serif font.

Calibri’s designer Lucas de Groot says, “Its proportions allow high impact in tightly set lines of big and small type alike.”

When anti-aliasing is applied, it is an attractive and very reader-friendly font; when it is not applied, Calibri looks like something I’d draw with my foot.

Font maven Megan McDermott observes that Calibri “looks terrible in Opera and Firefox,” an observation I don’t agree with, but since I respect her work, I’m passing along her opinion.



There are only two serif fonts in the “C” collection, and Cambria is, to my eye, the lesser of the two.

Microsoft states that Cambria was “designed for on-screen reading and to look good when printed at small sizes.

Designer Jelle Bosma calls it a “robust, all-purpose workhorse text face.” Van Wagener calls it “sturdy” and “formal.” I think the font lacks a certain elegance, though it is solid enough and is very strictly spaced.

If you’re interested in rendering mathematical equations, check out Cambria Math.


This sans-serif font incorporates some decorative flourishes, along the lines of Trebuchet MS and therefore is less useful in body text.


The only monospace font of the set, Consolas is as appealing as any monospaced font out there. I cordially despise everyone’s default monospace fault, Courier New, much preferring Andale Mono and other more stylish monospaces. Like Calibri, Lucas de Groot designed this font.


The other serif font of the collection, Constantia, is elegant without being overtly ornate. It’s clean, readable, and overall an excellent and versatile font.

Creator of the font, John Hudson, says he designed it to work in both print and electronic display formats.

On the screen, it looks very similar to Palatino Linotype or Book Antiqua, but with a bit more modern feel. Dan Cederholm of SimpleBits — in his quest to provide the best ampersand ever for use in your designs — finds Constantia’s ampersand (&) works well as a companion to Palatino/Palatino Linotype in the ampersand beautification code.


Corbel is the last of the sans-serif fonts in the collection. It is clean and readable, but to me, it suffers from some of the same design limitations as Cambria. Microsoft calls Corbel’s appearance “uncluttered and clean” on screen, and claims it is “legible, clear and functional at small sizes.”

“C” Fonts On Mobile Devices

It’s worth noting that mobile/handheld advocate Alexander Turcic says the “C” fonts are “gorgeous” on handheld devices. In 2005, he submitted 6 screenshots of the fonts in use on his iSilo device, including this example of Constantia in use below.

The Odd Ones Out: Segoe UI and Nyala

The Vista font collection contains two more fonts that are often forgotten in discussions of the collection: Segoe UI and Nyala.

Segoe UI

Segoe UI

A sans-serif font, Segoe UI is a member of a larger “Segoe” (pronounced “SEE-go” according to Microsoft designer, Jensen Harris) family of fonts. It has a lighter and more rounded feel than the “Swiss” fonts such as Helvetica and Arial, and is less linear than Tahoma.

It is Microsoft’s designated system font, replacing Tahoma in most Windows displays.

Microsoft blogger Saveen Reedy calls it a “beautiful” font, an assessment I agree with.

Some controversy over the font erupted in 2006, when the European Union declared Segoe UI to be a ripoff of another font (Frutiger Next) and refused to accept Microsoft’s registration applications for the font.

To be sure, there are slight but discernible differences between the two, but most people believe that Microsoft admitted some form of plagiarism when it decided not to appeal the EU’s decision. Designer Steve Matteson says Segoe UI is an entirely original design.

All legalities and disputes aside, Segoe UI is a terrific design choice if you have ClearType enabled, and if you’re comfortable with the heavy-handed anti-aliasing the technology provides. Without proper anti-aliasing, Segoe UI goes from strong yet delicate, to almost brutishly crude.



The least known of the eight Vista fonts, Nyala, is supplied with Windows Vista and Windows 7, as well as with Windows Server 8. It’s a restrainedly ornate serif font that — to my rather blurry eyes — appears a bit jagged in many displays. It’s also the only one of the eight Vista fonts that is virtually impossible to find for free if you don’t have it as part of your Windows installation.

According to Microsoft, “[t]he Nyala typeface is named for the mountain nyala (tragelaphus buxtoni) a species of great African antelope native to the highlands of Ethiopia.”

It was created by veteran font designer John Hudson (who, just as a reminder, also created Constantia) and is designed to reference native Ethiopian typography and lettering.

Design Issues in Using Vista Fonts

Designing with Vista fonts — both the “C” font collection and the two redheaded stepchildren — is problematic at best.

Certainly, by looks alone, most all of the fonts make excellent design choices, being elegant, attractive, and readable at a variety of font sizes.

And since they’re not the same old Web-safe font choices we see every single boring day, it gives both designers and users something fresh and different to see on their screens.

Market Penetration is Decent

Font embedding aside, we all know that it’s all but pointless to design with a font that no one has.

Microsoft is probably the only computer technology company in existence that can introduce a font — or in this case a group of fonts — that will achieve serious market penetration in the Windows user community within only a year.

That’s because the Vista fonts were included with Microsoft Windows Vista, Office for Windows 2007, and Office for Mac 2008. Suddenly, hundreds of thousands of potential Web users were gifted with almost a dozen new fonts.

So how many Windows users have them? The savants at CodeStyle can answer that question. Periodically, they issue an update of their survey of the fonts being used “in the wild” and what percentage of what users have what fonts.

As of CodeStyle’s June 2010 font survey results, the various “C” fonts seem to have a 60-61% market penetration among Windows users.

Segoe UI has a bit less, at around 51%. Nyala comes in a good bit lower, at around 43% of Windows users having that font on their machines.

A small but significant number of Mac users — about 13-15% — have the “C” fonts on their systems. For some perspective, that’s twice the percentage of Windows users who have Helvetica (the Mac equivalent of Arial) on their machines.

Linux users, which accounts for around 4.8%[2] of all Web users, pretty much don’t have any of these fonts: even the most common of the fonts, Calibri, doesn’t show up at all on the Linux font listing.

Is market penetration growing? The numbers for Windows users went up about 5% in just a month (from May to June) — a significant increase. This tells us that market penetration for these fonts is going up.

Quick recap: We can expect well over half of our Windows users to have the Vista “C” fonts, about 14% of our Mac users to have the “C” fonts, and our Linux visitors won’t have the fonts, period. There are signs that this will increase relatively rapidly.

What this means for web designers, though, is that while you can lead off with a Vista font in your font stack, you should have it followed (backed up) by fonts that are more universally available (Web-safe fonts) until these numbers reach higher percentages.

Size Really Does Matter

Unfortunately, the Vista fonts are tremendously small (think x-heights) in comparison to fonts that would ordinarily be used in font stacks with them, making it tough to design for them.

Or at least seven of them are; Segoe UI is larger than its seven siblings, and in its size, compares fairly well with fonts that it would likely be paired with, such as Verdana, Helvetica/Arial, and Tahoma.

Also, the size differential seems more pronounced on the “C” sans-serifs: Calibri, Candara, and Corbel. Some of the Vista fonts are so much smaller than their confreres that using them in front of your font stacks might throw off your design, especially if you’re designing a tightly structured, “count-the-pixels” layout.

You’ll probably find yourself compensating for their small sizes by increasing the font size of your designs, which may come back to bite you when your site displays on machines without these Vista fonts.

That’s a problem that has no real solution just yet, though it may be somewhat addressed when the @font-size-adjust property becomes more widespread.

Unfortunately, even @font-size-adjust won’t allow for adjustment for different fonts within a stack.

The guys at NeoSmart observe:

“They just don’t fit. The new fonts are mostly too small to be plugged right in to an existing CSS file. If you tweak the CSS so that it looks right for, say, Calibri; ten minutes later someone that doesn’t have that font is going to come around and ask your server for that CSS file — but since they don’t have Calibri installed, their browser will use the next one on the list, and unfortunately, your sizes are going to be all wrong.”

They eventually did tweak some stylesheets to accept Vista fonts, but it took some time, some testing, and a willingness to compromise on font sizing. They do note that Consolas works nicely in their designs without a lot of tweaking.

Brownspank at SixThings observes: “It may seem trivial for some, but if you’re aiming for consistency within your font-family, or are relying on subtle font size differences to enforce hierarchy, Vista fonts may adversely affect your layouts.”

McDermott notes: “It does make you wonder why this came about. Was it just ignorance on the part of their type designers? Negligence? Some underhanded way to make web pages look bad in other browsers so everyone has to use IE?”

Brownspank advises designers to set their font-size at a minimum of 14px or even 16px to ensure readability, and try to use Vista fonts that match their non-Vista cousins as closely as possible.

The ClearType Issue

Then there’s Microsoft’s ClearType. ClearType (CT for short) is an anti-aliasing (sometimes called font smoothing) utility first developed for Microsoft Reader in 2000, and is incorporated (turned off by default) in Windows XP.

It is enabled by default in Vista, Office 7, IE 7, and Windows Live Messenger. If you’re familiar with Adobe’s CoolType, Microsoft’s version is relatively similar.

Microsoft made the decision — foolishly, in my opinion — requiring ClearType to be enabled for these fonts to display properly, and designed them to CT specifications.

By doing so, they took 8 very usable fonts and made it much more difficult to justify using them in font stacks that are constructed to work on 99.9% of the browsers and displays out there.

Web designers, whether using Vista fonts or not, absolutely need to test their designs in Windows displays with ClearType enabled and again with it disabled.

Mac users have font smoothing operating all the time, so it will be less of an issue (or at least the same issue) for Mac folks. Mac font smoothing is pretty standard, with OS X using the Quartz anti-aliasing filter and Mac OS 8 and 9 systems using an older utility, QuickDraw[3]. Mac blogger Matt McErvin gives some more detailed information on both Quartz and QuickDraw’s anti-aliasing techniques.

ZDNet’s George Ou, writes that CT is superior to Quartz in rendering fonts on-screen. Blogger, Joel Spolsky, disagrees to an extent, positing that Quartz does a better job of rendering the typeface as it was originally designed, at the cost of a bit of blurriness. This debate addresses why some Safari for Mac users find the font displays unacceptably blurry.

Opinion is strongly split for and against anti-aliasing in general — and ClearType in particular. Personally, I like font smoothing because my eyes are bad and both my computer monitor and my glasses are old. I’ll take what I can get to help me see clearly.

Those with sharper vision and better monitors can, and do, disagree. Notable designer, Jon Tan, has a particularly acerbic take on ClearType, especially how it is implemented in IE 7. He concludes, “ClearType fails to deliver good anti-aliasing. In my view it is a backward step from the old Windows Standard rendering. I am at a complete loss to explain why it is allowed to persist.”

I might agree with Tan if my eyes were better.

ClearType For Programmers

Blogger, Jeff Atwood at Coding Horror would love to use Consolas as his default fixed-width programming font, if it wasn’t for the ClearType issue. He writes, “I’ll definitely agree that Consolas is one of the best looking ClearType fonts I’ve ever seen. That’s probably because it is part of the first font family designed from scratch with ClearType hinting in mind. However, I prefer not to use font smoothing on my programming fonts. And Consolas looks like crap without ClearType! Consolas appears to lack any kind of hinting for reasonable display at small point sizes. Consolas isn’t just optimized for ClearType, it can barely be used without it.”

Programmer Rick Stahl agrees with Atwood’s position, saying Consolas works for him only with ClearType enabled, and then only at 15pts.

However, programmer and math professor John Cook has a different view, saying that Consolas is his “favorite monospace font” in part “because it exaggerates the differences between some characters that may easily be confused.” He does not address the ClearType issue; presumably he’s enabled it and moved on (or he doesn’t use Windows).

Tweaking ClearType For You

It’s worth mentioning that Microsoft has a “power toy” available to fine-tune ClearType for XP and Vista users. Windows 7 folks have the utility in their Control Panel’s Appearance and Personalization applet. XP users also have an online version of the CT Power Toy available for their use.
