Banner sizes matter. If you’re displaying images on your sites, you need to make sure they follow standard practices.


When it comes to ads, banner sizes are even more important. If your sizes aren’t in order, your ads will appear laughable to your customers. But your banners must meet a certain standard no matter where you are displaying them.


In this article, we will cover which are the most effective banner sizes for different placements, and how to use them with best practices.

Why Banner Sizes Are Important

If you’re handling any kind of ads or social media pages, appearance is critical. Advertising and page banners must look good. But making a mistake regarding your images’ sizes will ruin the appearance of your ads. Sizes are one of the most important aspects of display advertising. Their impact on your ad performance is clear.


Consumers of any kind of display advertising become used to a certain appearance template. If your advertising looks out of place or irregular, people will process that information almost instantly. Beyond the basic psychology of your banner sizes, there are even more basic reasons you have to get the dimensions right. Using consistently correct sizes simply displays the content you need to be communicated most clearly. 


Despite their importance, using the wrong kind of banner image or banner ad is one of the most common mistakes in online marketing. Without awareness, it’s easy to make these mistakes when you’re making your own banner. Unfortunately, mistakes are costly in both time and money.


The good news is that you don’t need to make the same mistakes many online marketing beginners do. A little knowledge can go a long way in preventing waste in advertising. There are also plenty of great templates that you can use to make sure you never get the size wrong.

Medium Rectangle (300 x 250)

The medium rectangle (AKA Inline Rectangle) is the most common banner size in the global inventory. It’s also one of the more compact banner types. It won’t take up much space on your pages. It won’t take much bandwidth either, with most taking just up to 150 kb.


Advertisers love placing medium rectangle banners in different parts of an article. They are easy and convenient to display and can easily provide context for your content. Because it’s easy to make a good medium rectangle, it’s a good banner type for beginners.


You will often see a medium rectangle placed on the far right or left side of a webpage, alongside written content.

Wide Skyscraper (160 x 600)

Often found scratching most of the side of a webpage, the appearance of the wide skyscraper is self-explanatory. However, you may also hear of a “standing banner”, which is just a wide skyscraper by a different name.


Wide skyscraper banners make about one either of the global banner inventory. If you surf the web often, that won’t be much of a surprise. Many webpages feature ads running down one or both sides of the page.


There are alternative templates to the wide skyscraper. The normal “skyscraper” banner is 40 pixels less wide. But it’s not nearly as common as the wide skyscraper, which just happens to convert better.


Wide skyscraper ads tend to be safer bets than other banner types. They convert well as either image ads or with content plastered on them.


No webpage is complete without a wide skyscraper or at least a skyscraper. But as mobile browsing becomes more common, skyscrapers are becoming less useful. But there’s still no excuse to not have them in your inventory.

Leaderboard (728 x 90)

 A leaderboard banner is an extremely horizontal banner. It’s the 2nd most common in global inventory. You see these banners all the time, as they’re likely the first ones you see on web pages.


As the name implies, a leaderboard is a more prominently displayed banner. They normally start at a minimum of 150 kb. It’s displayed at the top of webpages, often alongside a medium rectangle or another small banner.


Your page’s leaderboard is its first impression. But in many cases, it’s also the last impression, as a leaderboard is very often placed at the bottom of a page. 


Normally, these banners are best placed at the top and bottom of the page. When a visitor scrolls to the bottom of a page, they will usually feel like they’ve reached the end of it and want to click somewhere else. A well-made leaderboard with a link will help them satiate that urge.

Halfpage (300 x 600)

This is another somewhat common banner that is essentially a much larger skyscraper. It will usually appear quite clunky, so you should only use it strategically.

Large Leaderboard (970 x 90)

This alternative to the leaderboard is simply a larger version of it. It’s far less common than the original leaderboard. But it’s still an option you have if you want to mix things up.


Online ad platforms have their own standards for banner sizes. If your marketing strategy involves social media, you will need to consider the banners that are used for the most common ads platforms.


Each banner mentioned above is normally used on a webpage ad.

Facebook Ads 

Competitive businesses try to use the world’s biggest social network, Facebook, to grab attention. Facebook ads are displayed on the desktop and mobile homepages. Your ads will show up on Facebook in the News Feed, among updates and posts from Facebook friends, pages, and groups.


You will need to use the same image size that is displayed in the News Feed. This is normally done with an interesting, eye-catching image of one of your products. Below the image, your site and ad text will be displayed.


Facebook recommends every ad image be at least 1080 x 1080 pixels. Images must be saved as either JPG or PNG. The maximum size is 30,000 kb.

Facebook Pages

If you’re advertising on Facebook, you must have a page on the platform. Your Facebook page’s photos should be displayed clearly to be effective.


Your page’s cover photo will be displayed at 820 x 312 pixels on a computer. Mobile pages display them at 640 x 360 pixels. They must be at least 400 pixels wide and 150 pixels tall to be uploaded at all.

Google Mobile Ads Overview

When you’re advertising for Google’s mobile audience, there are different banner sizes.

Mobile Leaderboard (320 x 50)
