What are common online ad sizes, per the IAB Display Advertising Guidelines?

For standard ad sizes, please refer to the IAB, which publishes standards and best practices for online and mobile advertising, including videos. The IAB sets the standard for advertising in the publishing industry. Companies that frequently advertise across the Web will be familiar with these size options.

The IAB publishes a PDF with all guidelines for advertising, which can serve as a quick and easy reference guide as you develop your advertising packages. Find that here: http://www.iab.com/wp-content/uploads/2015/11/IAB_Display_Mobile_Creative_Guidelines_HTML5_2015.pdf

 

The IAB website also provides guidance on file size for these standard sizes. Find details here: http://www.iab.com/guidelines/universal-ad-package/
