Kinds of Instagram ads

Before we can dive headfirst into Instagram advertising specs, let’s first talk about the different kinds of Instagram ads you can use.

Instagram image ads

An Instagram image ad is likely familiar to your feed. These ads show up in the form of, you guessed it — an image, and they usually include some sort of call to action (CTA), like “shop now” or “learn more.”

Use Instagram image ads if: You want to advertise your products without being intrusive, or you’re just getting your feet wet with Instagram ads.

Instagram story image ads

Instagram story image ads appear in a company’s Instagram story. They take the form of a static image and usually have a text overlay and an option to “swipe up” to learn more or purchase the product.

Use Instagram story image ads if: You want to broaden the reach of your original image ad, or if you want to show up in more than one place. (Assuming you also run an in-feed image ad.)

Instagram video ads

Instagram video ads allow you to show off the way a product works, fits, or even a drastic before and after. Video ads grab users’ attention and feature a CTA to encourage clicks.

Use Instagram video ads if: You want to show your audience something about your product that you can only show with video, or if you want to go the extra mile to engage users.

Instagram story video ads

Instagram story video ads are like regular video ads except instead of showing up in users’ feeds, they show up in user stories. They feature a CTA, too!

Use Instagram story video ads if: You want to engage users in their stories.

Instagram carousel ads

Instagram carousel ads allow you to advertise more than one product in a single ad. Users simply use an arrow to skip through products, and each card has a CTA.

Use Instagram carousel ads if: You want to advertise more than one product with a single ad, or if you want to make it easy for users to shop for a group of related items at the same time.

Instagram slideshow ads

Instagram slideshow ads create an engaging experience for users. When they scroll past a slideshow ad, they’ll see a loop of different pictures that you select that play automatically, like a video.

Use Instagram slideshow ads if: You want the look of a video but don’t want to put in the work to create an actual video.

Why follow Instagram ad specs?

So, what does it matter if you’re off a few pixels, or you submit an ad with too much text?

You might be wondering why Instagram ad specs are so vital that we wrote a whole page on the topic. Allow us to enlighten you.

Here are some potential pitfalls of not following Instagram ad specs:

  • Facebook will deny your ads. Remember, Facebook owns Instagram, so you’ll create your Instagram ads on the Facebook platform. If you don’t follow Instagram advertising specs, Facebook could deny your ads — leaving you high and dry. You can of course fix your ad and try again, but if you want to save time, get your Instagram ad specs right the first time!

  • Your ads will appear grainy or skewed. If you don’t follow Instagram ad specs, you could find that your photos or videos appear grainy or skewed. Instagram created ad specs for a reason, and it’s in your best interest to follow them if you want beautiful, effective ads.

  • They'll be ineffective. Users likely won’t trust a product that appears grainy. That’s why you should always select images and videos that follow Instagram’s recommended resolution, image size, and aspect ratio.
