The Best Instagram Ad Size for Every Post Format

Best Instagram Ad Size

Ever since their release, Instagram ads have been an advertiser’s dream. You’ve got a visual platform that’s primarily used by mobile users, eliminating other distractions on the screen and a highly engaged audience that’s actually excited to discover and engage with brands they love.

Instagram ads can yield exceptional results, which I’ve seen firsthand when writing PPC copy for my clients. And while the text does matter, the images and videos are crucial, especially since they appear above the text on Instagram. This may be even more true on Instagram than on Facebook.

We want to help you harness the incredible power of Instagram ads, so in this post, we’re going to discuss the ideal Instagram ad size for every format and look at general best practices.

Instagram Ad Sizes for Every Advertising Format

Choosing the right ad size before you ever upload your images into Facebook’s Ads Manager is a good call.

It gives you full control over how your videos and images are displayed. The last thing you want is a weird crop happening that cuts off a vital part of your CTA in a Story, or a crucial part of an image to establish context.

Having an incorrectly sized or cropped ad on Instagram can be enough to have a negative impact on your campaign and make it look like you’ve made a lazy marketing mistake — you don’t want either of those things to happen, as it can derail your campaigns quickly, especially with cold audiences.

The perfect Instagram ad size varies, and each individual ad format has its own unique requirements. Let’s take a look at each.

General Requirements

Different ad formats require different image sizes, but there are a few things that they all have in common. These requirements include:

  • Ad image files should be either JPG or PNG.
  • The max ad image file size is 30MB.
  • Caption text can be up to 2,200 characters, but it’s best to keep them between 135-150.
  • MP4 files are preferred for the best Instagram video format.
  • The max video file size is 4GB.
  • All images and video thumbnails can’t contain text that occupies more than 20% of the image space. You could put your ad at risk for losing placements or even be declined during ad approval.

Instagram Newsfeed Ads

Instagram newsfeed ads can come in three different formats: landscape, square, and vertical. These are the ideal Instagram ad sizes:

  • Landscape image ad sizes should be 1200 x 628 pixels, and have an aspect ratio of 1.9:1.

  • Square images should have a 1:1 ratio, and use 1080 x 1080 pixels.
  • Vertical image ad sizes should be 600 x 750 pixels, with an aspect ratio of 4:5.Instagram ad size

Instagram Carousel Ads

Carousel ads –sometimes called “multi-image” or “multi-product” ads– allow brands to create up to 10 different slides containing images or videos that users can swipe through. 

They’re historically known for much higher than average click-through rates and conversion rates (though may sometimes not perform as well as single-image posts on Instagram). Test them for yourself, and use our ready-made templates through Snappa to create images like the one below:

Carousel ads use square images or videos, so you’ll use the 1:1 aspect ratios here, which translates to 1080 x 1080 pixels.

Instagram Story Ads

Instagram Story Ads are a fullscreen mobile “experience,” taking up a user’s entire screen and hopefully their entire attention span. 

Video ads here can be up to 15 seconds long, and single images will appear for five seconds. We recommend testing both, along with testing the option of syncing several screens with graphics & text together in a video with music.

Something else to consider here is that the “Shop now” CTAs and navigation will take up the bottom central and right part of your ad, and your brand name and logo will take up the top left corner. 

Account for this during the creation stage. This will ensure no key design elements or information will be accidentally cropped out when the ad goes live. Our Stories templates automatically account for this, showing you what space to leave blank:IG Story Ad Example

Instagram Ad Best Practices

Success on Instagram ads depends on a little more than just having perfectly sized images. There are other best practices you should implement when creating your campaigns to ensure that your ads are relevant to your target audience, and thus well-positioned for a great ROI on your ad spend. 

Let’s look at the Instagram ad sizes and overall best practices you don’t want to forget. 

  • Choose your targeting well. Instagram utilizes Facebook’s astonishingly detailed targeting system. You can target customers who have already purchased from you with an up-sell, or target pet owners to show them an IG ad with an adorable animal doing the selling for you. The options are limitless. Get exactly as detailed as you need to in order to reach your audience niche… but no more than that.

  • Start with the right size image. This will save you a ton of time in the ad creation process. Here at Snappa, we have customizable pre-made templates available for landscape and square ad formats, but you can start new designs from scratch with any of the ad dimensions you want to use. Start with the right size so you don’t have to work backwards later.

  • Use your copy to convey value. Your images and videos should capture user attention. That’s important. In many cases, though, it will be up to your copy in the caption to really convey why your offer is valuable. Talk about how your product can solve pain points, or what features make it unique. This will go a long way in driving actions.

  • Tell stories. As a copywriter, stories are my secret superpower. When you’re able to tell even a short, quick story like “Tired of coming home every night exhausted? Get your energy back!” can hammer in that emotional appeal. Here’s a great example from one of our templates: “Time to rest & reset” as the core tagline on the image, with information encouraging users to take action.Instagram ad call to actionsIf you’re stumped, start repurposing: customer testimonials can work well for this. A go-to move is to add snippets of well-written and enthusiastic reviews onto the images or videos themself with text overlay. You can see a quick swap we made here from the template above:

Conclusion

Instagram ads can drive outstanding results. They’re capable of attracting a large number of qualified leads and sales (depending on what you’re optimizing for!) at a relatively low cost. Getting those results will depend heavily on creating strong, customer-oriented campaigns, and using the right Instagram image ad sizes will be crucial.

There are plenty of ad formats to choose from, which means that you’ll wan to create multiple different visuals to take the Instagram ad sizes into account. 

While it’s a good idea to run tests to determine audience response, always make sure that the visuals are perfectly sized and cropped. It’s a simple process to ensure that your ads look perfect, and it can have a big and very profitable impact on your campaigns.
