What’s the best Instagram image size for 2021?

Square Posts (1:1): Make your square photos 1080px by 1080px in size. That way, when Instagram compresses the file and the version will still be high quality.

Horizontal Posts (16:9): While Instagram recommends an aspect ratio of 1.91:1, you can go as far as 16:9.

Vertical Posts (4:5): Your vertical photos should have an aspect ratio of 4:5. Anything longer (like 4:6 or 4:7), and Instagram will crop your content.

Do Instagram photos have to be square?

No, your Instagram photos don’t have to be square. You can also upload rectangular portraits and landscape photos to your grid without cropping. Make sure that your photo is up to 1080px on the shortest side.  If you upload a photo that exceeds the aspect ratios (the width-to-height ratio of a photo), you’ll have to crop your photo.

Now, let’s talk about the best image size for Instagram photo posts, including the traditional square, portrait, and landscape.

You can post a landscape image in a 1.91 to 1 aspect ratio, which is exactly the same as a Facebook link preview image. That means you can easily use the same image on both platforms.

If you do post a wide (or tall) image, be aware that it will be cropped to a square in your image gallery.

The portrait or square image is the best for the Instagram stream.

The best not-square size is the 1080 pixels width and 1350 pixels tall. If your photo is larger, it’s ok, Instagram will reduce it when you post.

Try not to post a smaller pixel size, though, as your image will lose quality when viewed on most devices.

The Instagram portrait aspect ratio (or proportion) is a rectangle and is the same as an 8 x 10 portrait photo.

You’ll find the aspect ratio 4:5 or 8:10 offered as a cropping option in your photo editing app.

Why is my Instagram photo post not 1080 pixels wide?

  • When you share a photo on Instagram it automatically posts at the best quality resolution possible (up to 1080 pixels wide).
  • There are a few reasons you may be seeing lower resolution photos on Instagram: Photos between 320 x 320 and 1080 x 1080 pixels will post at their original resolution.
  • The desktop version of Instagram only displays up to 640 px images.
  • Your phone might not take and/or support high-resolution photos.
  • NOTE: If you share a photo at a lower resolution than 320 pixels wide, it’ll be enlarged to 320 (and will probably look terrible).
  • If you share a photo at a higher resolution, it’ll be sized down to 1080.

Why you might want larger Instagram photo size

If you have Save Original Photos set to ON in your Instagram settings, your edited photo is saved at its full resolution to your device’s photo library.

If you want to use the photo to make prints where you need a high resolution, post your Instagram images as large as needed for later use.

Post 1080px square if possible – even larger if you want to ensure you can reuse the image at top quality next year! Who knows, the size may increase again by then.

Font size for Instagram post?

You can change your font size by going to Settings > Display & Brightness > Text Size and adjust to your liking. Most of Instagram uses the Neue Helvetica font.

Instagram post pixel size?

All Instagram posts have the same width (1,080 pixels), which is the size of your phone’s screen.

Instagram post size ratio?

1.91:1 is the Instagram post size ratio. While Instagram recommends a post ratio of 1.91:1, you can actually go as far as 16:9. In any case, we recommend you make the height of your horizontal photo at least 1080px. That way, when Instagram compresses the file, the quality should remain pretty high.

What is IGTV?

IGTV is a long-form video on Instagram. IGTV is a stand-alone video application by Instagram for Android and iOS smartphones. It allows for longer videos compared to Instagram feeds. While IGTV is available as a stand-alone app, basic functionality is also available within the Instagram app and website.

Instagram says:

Five years after the launch of video on Instagram, we are excited to introduce IGTV, which brings audiences closer to the creators they love.

We are re-envisioning mobile video with a new stand-alone surface that features longer videos and easy discoverability through channels, all in a vertical format that sits upright, in the palm of your hand.

We’re evolving with the times; these days, people are watching less TV and more digital video. By 2021, mobile video will account for 78% of total mobile data traffic. And we’ve learned that younger audiences are spending more time with amateur content creators and less time with professionals.

IGTV is:

  • Mobile-first: IGTV is built for how you actually use your phone: vertical and full screen.
  • Simple and intuitive: It starts playing as soon as you open the app. You don’t have to search or browse to get started, and it’s easy to multitask.
  • Curated: IGTV is focused on the creators you love most and already follow on Instagram.
  • Anyone can be a creator on IGTV and upload videos in the app or on the web.

What IGTV means for businesses:  longer vertical video on Instagram makes it even easier to get closer to your audience and be discovered by new people.

Use longer, permanent video for deeper storytelling. Build stronger connections with potential customers as you showcase other dimensions of your business without being limited to one type of content, length, or format.

Grow your community! As with Instagram stories, IGTV is built on Instagram, leveraging a global community of more than 1 billion people. When your followers open IGTV, they will instantly see original content from you, and new people can also discover your brand.
