One of the more commonly requested features that I see AdSense publishers making is for the ability to be able to change font size in their ads.
The AdSense blog today announces this change:
“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.
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 announced in the post is that the default size for ads will soon be automatically increased from ‘small’ to ‘medium’. This is due to testing that they’ve done which shows that larger size is performing better.
