According to Google, these are the most common ad sizes you should consider. On top of that, we’ve made you a mention of the top performing banner ad sizes, so check them out:
Medium rectangle (ad size 300 × 250)
This type of banner ad is the most compact of all these options, so it doesn’t take up too much space on a website. It works well when embedded in textual content or when it is placed at the end of an article. Because of its compact size, advertisers tend to prefer it because it is convenient to display. Also, it’s a good choice when you’re just getting started with display ads.
Large rectangle (ad size 336 × 280)
While this ad size doesn’t get as many impressions as the first, it’s still a popular choice for advertisers. Since it is similar to the Medium rectangle, it works best when placed within body text or at the bottom of a post. Since it is slightly larger than the 300×250 ad size, that means you will have more inventory.
Leaderboard (728×90 ad size)
This type of banner ad is called Leaderboard because it is usually displayed at the top of the web page. If you want to show your ad in front of as many other ads as possible, this is a good option to consider. Also, because you get more inventory.
Half page or large skyscraper (ad size 300 × 600)
This ad takes up the most space compared to other large banners. This means you will have more room for your message to get noticed. But this comes with the pressure of needing to create images that are stunning and draw people in and get them to click on your ad.
Mobile leaderboard (ad size 320 × 50)
As the name implies, this ad format is optimized for mobile devices. While this is one of the smallest mobile banner sizes available, it should definitely be used as a way to maximize impressions and improve mobile CTR.
These trigger sizes are just the first step in creating a banner ad. Other aspects you should consider are:
