Font size matters - CreateAdsense

Since February, you've been able to change the font faces of your ad units. We're now happy to announce the launch of a related feature you've been asking for -- the ability to change the font size of the text in your ad units. You can now select from small, medium, and large font sizes for ad units on pages in Latin-character languages. Just like with the current font face options, size options appear in every account but will only be applied to ad units on pages primarily in Latin-based characters for now.

The font size you choose will be applied to the body of the ad, with the title scaled appropriately. In order to fit the ad text correctly, the actual font size will vary for each format size, font face, and user-specific settings such as browsers and operating systems. In addition, some formats sizes currently have very limited room, so the font size application will be most apparent in cases where the number of ads appearing in your ad units varies automatically in order to maximize your performance. Here's an example of what the three font sizes could look like in a 336x250 large rectangle:

Your ads are currently set at the default size for AdSense, which is the equivalent of 'small'. You can select a new font size on an account-wide basis in the Ad Display Preference section of your My Account tab, or on an individual ad unit basis for new and existing ad units.

If you're creating new ad units, you can choose between the AdSense default font size, your new account-wide font size (if you've selected one using the instructions above), or a separate size. To update existing ad units you've created using the Manage Ads feature, visit the 'Manage Ads' page under your AdSense Setup tab. Any font size changes you make on an individual ad unit basis will be maintained even if you change your account-wide default in the future.

Also, a bit of advance notice: soon, we'll also be changing the default font size across AdSense in ad units from 'small' to 'medium'. We've heard from some of you that the current font size can be too small, and our testing also showed that slightly larger font sizes improved performance. Any ad units set to the default font size will automatically be updated to display the larger setting. If you'd prefer to stick with today's font size, you can set your desired font size as 'small' across your account.

We encourage you to combine these new font size options with the other customization options in your account to test the optimal layout for your pages. We're excited about this launch, and we'll be sure to follow up with another post to let you know once the default font size has been changed.

Updated to include an example of each of the three font sizes
