As you probably have noticed, the mobile phone market has moved towards bigger screens – more than 55% of the global mobile phone market is on high aspect ratio screens.
Comparison between high and low aspect ratio devices:
What does this affect?
You should only worry about the different screen sizes when you use mobile fullscreen ads. These ads are overlaid or cover the content of the website or app.
What to notice while creating fullscreen ads?
As a rule of thumb, the creative design or positioning of the assets should be done so that:
the background covers full height (using assets in size up to 640 x 1280 px). This ensures that there are now black or white areas outside the ad.
important content is within the “safe area” (in the center with a maximum height of 854 px). This ensures that essential info appears even on smaller screens.
Designers use "safe areas" to ensure that your ads look great on all screens. You should also use them when creating fullscreen ads:
Our Scale and Crop tool will help you position the asset within the limits. By default, the "safe area" lines are shown on the ad. You have also the possibility to see the ad without them or see the ad with browser bars:
When previewing the creative, you can also see how it is shown on high or low aspect ratio devices and with/without browser bars:
What also to consider while creating fullscreen ads?
When using types Interstitial and Expandable, you'll have the opportunity to choose between Fullscreen (low aspect ratio) and Fullscreen (high aspect ratio) placement sizes. As explained above, the low aspect ratio should be selected in cases you are sure that no ad viewer is using a high aspect ratio device.
When using the type Interscroller, you won't have the opportunity to choose your own creative size. It'll appear by default in a high aspect ratio size, so it looks nice on all devices.
If you are using our regular layouts, you don't have to worry when you place a CTA button or logo asset out of the "safe area" neither. It'll appear by default in the right place depending on the size of the screen visible area and will not disappear if the device is not a high aspect ratio one.
