Mobile banner advertising has created a host of new concerns for advertisers looking to use this new format. File sizes, screen sizes, and more can all contribute to the design of a mobile landing page. It’s important that you consider screen size, and how your banners will look. Extensive testing will help find the best ad designs for mobile phones.

Feature and Smartphone Sizes

Feature phones are Web enabled, but don’t have the applications that a smartphone has. These phones will display Web pages, for instance, but may not support rich media. A small ad at this size can be 120×20, but sizes go all the way up to the feature phone large banner at 216×36. Smartphones can be a little more liberal with sizes. These ads are usually at least 300 pixels wide, but can go as high as 320. The smartphone static interstitial is one of the widest, measuring at 250 pixels.

Efficiency Tips

It’s recommended that you save your ad image in a format that allows for smaller file sizes. PNG is excellent for this reason. Jpeg at lower resolutions won’t look crisp and can look tacky. GIF images are still the standard for rich media ads, but you should pay close attention to how many frames you add to a file to keep sizes manageable.

Forms and Buttons

Make everything on your display advertising easy to read. The user shouldn’t have to pinch to zoom if you can avoid it, but you should also make buttons prominent and easy to tap.
