Decoding the Different Banner Sizes

The Leader of the Pack: Leaderboard


The leaderboard ad, with its 728 x 90 pixels size, is the frontrunner in the race of web ads. Typically placed at the top of a page, it immediately captures the user’s attention, making it a favorite among advertisers.  

The Text Breaker: Large Rectangle


Tucked neatly between the paragraphs or at the end of a text, the 336 x 280 pixels large rectangle ad works wonders in breaking the monotony of text and drawing the reader’s eye.

The High Performer: Medium Rectangle (MREC)


Also known as a square ad, this 300 x 250 pixels ad unit may be smaller than the leaderboard, but it punches well above its weight in terms of performance. Best placed near the top of a webpage, before the fold, it ensures maximum visibility.

The Long Stayer: Wide Skyscraper


With its impressive 160 x 600 pixels size, the wide skyscraper ad, like its namesake, stays within the user’s line of sight even when scrolling, holding attention for longer.

The Space Saver: Skyscraper


When space is a constraint, the 120 x 600 pixels skyscraper ad comes to the rescue, fitting snugly into narrow spaces.

The Brand Builders: Button 1 and Button 2


Ideal for branding and co-sharing purposes, these small-sized ads (Button 1 is 120 x 90 pixels and Button 2 is 120 x 60 pixels) are excellent for sharing images as part of a branding exercise.

The Transition Expert: Microbar


Though small in size (88 x 31 pixels), the microbar is big on functionality, serving as a perfect bar to transition to a different page.
