300×1050 Ad Unit / Portrait Ad
The 300×1050 Ad Unit is one of the IAB’s Rising Star Ad Unit category and is one of the largest sized ad units currently in market.
The 300×1050 Portrait Ad Unit is typically positioned in the right-hand side bar of a website (designed for 300 pixels wide) and because of its large size, not every publisher’s website can handle it. The 300×1050 typically replaces at least two standard IAB Ad Units.
