160×600 – Skyscraper

What is a 160×600?

The 160×600 ad size is an IAB standard ad unit with the dimensions of 160 pixels wide by 600 pixels tall. This ad size is known as a skyscraper ad, a super skyscraper or sometimes a wide skyscraper.

The 160×600 ad size is generally placed on the side of a page, so as to show users an ad as they scroll down the page. This makes skyscrapers (of both types) somewhat immune to demands for above the fold placements.

The 160×600 was brought in to replace the old 120×600 skyscraper ad unit because of it’s consistently better performance (due to being very large compared with the 120×600). The 120×600 however still remains somewhat frequently in use so should not be ignored. The 160×600 is still more commonly served through a multi-size ad slot with a 120×600 ad unit, so that either ad size can appear in the same ad slot.

Both the 120×600 and 160×600 ad slot are less popular than 728x90s or 300x250s, yet should still be placed on every page of a site for incremental revenue.

160×600 Advice for Site Owners

You can generally expect a reasonable CPM for this ad unit, however it will often be lower than the 728×90 or 300×250.

If placed aligned with a 300×250 along the right side of a webpage, this ad unit can make up part of a homepage takeover.

This ad slot is often difficult to fill (whether using a 120×600 or 160×600) due to lack of demand, so having both options available is the best choice.

Tip: Placing CPA adverts in the skyscraper slot is a good idea, as they will ensure your users have cookies in place for post-impression sales.


160×600 Advice for Ad Buyers

We would recommend using when building your own advertising. It will not always be your best performer, however it is does pretty well usually.

Salespeople will often try and convince ad buyers that this unit is good because it remains on a user’s page for longer, however it is not better than a 728×90 or 300×250 in most cases.

You should expect to pay slightly less than a 300×250 or 728×90 ad unit for a 160×600.
