How to Generate Responsive Sizes from your PSD File

970x808 with an IAB Pack

IAB packs and formats, for example the IAB Pack (Fully-Fluid™), are used when you are targeting IAB slots. Designing for IAB involves working with smaller ad slots, and thus a different size of PSD is better.

Starting from a layout that is close to a square aspect will speed up generating all the other aspect ratios included in the IAB standard, so we recommend targeting the 300x250px.

As the IAB standard also includes sizes ranging from 970x250 to 300x600, we recommend building the ad design in Photoshop at 970x808px size. This gives you assets that are large enough to display beautifully in all the IAB sizes.

Follow the below instructions to import the 3 times larger size correctly to the 300x250 size in your IAB Pack.

Before you upload, verify your active size(s)

• Remove any unwanted layouts, keeping only the 300x250 active and selected

After uploading, adjust from pixels to percentages

• Click the crosshairs to reset to 100%x100%

• contain-> cover, text, anchors, locks, buttons

Select the next size and verify your adjustments
