A Skyscraper is an online ad significantly taller than the 120x240 vertical banner.

Skyscraper ads are tall with heights often ranging from 500 to 800 pixels (and widths often ranging from 120 to 160 pixels). For a long time there was no standard sizes to which buyers and sellers adhered. This made skyscraper ads the province of large, well-branded sites that could sell custom advertising packages.

The IAB has since announced standard sizes for skyscraper ads. The standard skyscraper is 120x600 and the wide skyscraper is 160x600. With standards in place, skyscraper ads became more common at advertising networks.

Skyscraper ads are often called skyscraper banners, although some examples have mimicked the look of a banner by using a combination of ad buttons and text.
