In order to be successful with your online advertising, it is important to understand the different ad sizes and know which ones work best for your business. In this article, we will discuss the best-performing ad size and why it is the best choice for your campaigns. We will also provide tips on how you can create effective ads in this size and troubleshoot any issues that you may have.

Some Common Ad Sizes

Here are some of the most common ad sizes that you will come across! All of these sizes fit a certain ad type and style, and finding the right one for you will require some testing and experimenting on your part!

But let's mention common ad sizes across most platforms!

Banner (320x50)

Used for displaying ads on phones and tablets, the regular banner is wide yet slim, so it can fit in most spaces. Compared to other ad sizes, this one is often considered to lack the proper punch to get customers right away!

Large Banner (320×100)

Mobile is probably the most important advertising space right now, and these banners are only shown on mobile and tablet devices! This makes them ideal for use in most situations. They also double the px height of the other standard mobile banner sizes which often makes them more eye-catching to users.

Medium Rectangle (300×250)

The medium rectangle display ad size is popular among advertisers since it works well for Mobile, Text, and Display. 300x250 px adverts are most commonly found within text content or towards the end of publications. They are big enough to catch someone's attention, but not big enough to bother the average user.

Large Rectangle (336×280)

The large rectangle display ad size doesn't function for mobile display advertisements, but it performs well on desktop and tablet displays. Most of these display ads are featured at the end of the content and they are usually embedded.

Leaderboard (728×90)

On forums, leaderboards are common and perform well at the top of the page, above the primary content. They give users a quick glance at the ad without interrupting their routine too much.

Half Page (300×600)

Half pages are used when advertisers want to go all out with their message. These ads are usually reserved for occasions when you want to say a powerful message and capture the attention of users right away!


Adaptive banners are a special type of banner that can be cropped and adapted to properly fit multiple placements at once. There isn't any standard resolution for this, but most platforms, if not all, have some sort of adaptive banner which you can utilize.

What is the best-performing ad size?

The best-performing ad size will vary depending on the platform you are running your ads on. Most platforms have recommended sizes (resolutions, and aspect ratios) for their ads, and these are typically the sizes that perform the best. That being said, it is always a good idea to test different sizes to see what works best for your specific business and campaigns.

However, some general tips that can help improve performance include:


Make sure that the ad is visible and catches the reader's attention. You can use bold colors and interesting designs to attract people. Try researching where your ad will be placed and see what color palette the website uses. If you can,  try to use contrasting colors in your ad so that it stands out.

Also, make sure you have interesting images that are in the right resolution. People are more likely to engage with an ad if it has high-quality visuals.

High-quality Images

Use high-quality images or videos to make the ad more visually appealing. As we mentioned before, people are more likely to engage with an ad if it has high-quality visuals.

Make sure the images or videos you use are in focus and correctly sized for the ad. You don't want the image to be too small or too big. Stock footage sites like Shutterstock, Pexels, iStockPhoto, and many other services can help you get the perfect image with the right permissions to post.

It's also important to make sure that the image is relevant to the product or service you are promoting.

If you are using videos, make sure they are high-quality and have subtitles so that people can understand them without having to turn on the sound.

Use strong headlines

Use strong headlines and persuasive copy to encourage people to click on the ad. Most of the internet is full of clickbait, so make sure your headline is something that people will want to click on.

Your headline should be clear and concise, and it should tell the reader what they can expect when they click on the ad.

You can try asking the readers a question, or giving them a mystery that they need to click on and read through to learn more about!


The layout of your ad is also important. Make sure the ad is easy to read and navigate. Use clear fonts and simple designs.

If your ad is too cluttered, people will be turned off and less likely to engage with it.

You want people to be able to understand the message of the ad quickly and easily.


Your call-to-action (CTA) should be clear and visible and it should encourage people to take the desired action. The CTA is what tells the reader what you want them to do, whether it's clicking on a link, signing up for a newsletter, or purchasing a product.

Your CTA should be in a contrasting color so that it stands out from the rest of the ad. And it should be placed in a spot where people will see it easily.

It's also important to make sure that the CTA is relevant to the ad. For example, if you are selling a product, your CTA should be something like "Buy Now" or "Shop Now."

Test your sizes and placements

Test different ad sizes and placements to see which performs best for your business/campaign. Not all ad sizes will work for every business, so it's important to test and see what works best for you.

You can use A/B testing to test different versions of your ad. This is where you create two versions of your ad and then show them to different people to see which one performs better.

You can also test different placements of your ad. This is where you would try putting the ad in different spots on the page and see which spot gets more clicks.

Track performance and adjust

Make sure to track the performance of your ad and adjust accordingly. You can use Google Analytics or other tools to see how people are interacting with your ad.

If you're not getting the results you want, try changing the ad slightly and see if that makes a difference. Sometimes it's just a small change that can make a big difference in performance.

Remember to keep testing and adjusting until you find what works best for your business!


When it comes to ad performance, there is no one-size-fits-all answer. The best-performing ad size will vary depending on the platform.  For example, native ads tend to perform better on social media, while display ads work better on websites.

It's important to experiment with different ad sizes and formats to see what works best for your business. Try out different sizes and placements and track the results so that you can best judge the performance.
