Do you constantly find yourself in the dark about post sizes?

Who can actually tell you what size your images should be on different social platforms?

Wouldn’t it be a game changer to have all the info on post sizes you need, up-to-date and clearly presented in a no-nonsense guide?

Looks like you’ve come to the right blog post! This guide regroups all the optimal image post sizes across ten social platforms, so you don’t have to dig around for the correct size every time you want to share something new.

Ready to go?

1. Facebook image post sizes

Let’s start off with some Facebook basics. Your profile pic should measure 180 x 180 pixels and your cover image 820 x 312 pixels. Get those right, and you’re already off to a good start!

Here’s a breakdown of the best post sizes for all the different kinds of Facebook posts:

  • Feed post image: 940 x 788 pixels
  • Feed ad & shared link image: 1200 x 628 pixels
  • Facebook Stories: 1080 x 1920 pixels
  • Facebook Carousel: 600 x 600 pixels

Also good to know, if you’re organizing an event on Facebook and want to use the perfect image to illustrate your event page, 1920 x 1080 pixels is the perfect size for that image. Using ready-to-use Facebook banner templates can come in very handy, too!

2. Instagram image post sizes

Instagram, the king of social images! The Instagram Gods will not forgive you for getting these wrong… 😅 Here are the ideal post sizes, from the obvious to the not-so-obvious:

Your profile pic should be 110 x 110 pixels. An image this size will be perfectly centered into the circle your profile picture is displayed as in your Instagram bio.


A square post — whether an image or a video — needs to measure 1080 x 1080 pixels for the best quality in the feed, and oblong posts (portrait or landscape) need to be 1080 x 1350 pixels. The same measurements apply to feed ads.

Instagram Stories — posts and ads — need to measure 1080 x 1920 pixels. That’s if you’re creating a visual especially for that purpose… otherwise just take a pic with your phone’s camera directly from the Instagram app 🤳.

3. Twitter image post sizes

Twitter may be all about the short, snappy sentences, but visuals also have their place on the platform. Do them justice by following these size guidelines.

On Twitter, your profile pic would ideally be 400 x 400 pixels and your cover image should be 1500 x 500 pixels. That’s the easy bit. Now you’ve just got to decide which image to use for your cover… 🤔 The eternal battle!

4. LinkedIn image post sizes

Think LinkedIn is just about recruitment posts? Think again. LinkedIn is definitely gaining in funky content, and that includes images, which are of increasing importance on the platform.

Let’s start off with the basics. Your LinkedIn profile picture should be 400 x 400 pixels and your cover image 1584 x 396 pixels (or 1536 x 768 pixels for a company page cover).


The optimal size for images on LinkedIn is 180 x 110 pixels.


5. Pinterest image post sizes

So, Pinterest is indisputably all about the visuals. So let’s start off by getting your first images on the platform completely right:

  • Profile pic: 165 x 165 pixels
  • Board cover: 222 x 150 pixels


Here’s some important news for all the Pinterest enthusiasts: a 2:3 Pin will never appear larger than 564 x 846. So that means the 735 x 1102 pixel size that everyone was used to using is out the window. Pinterest recently said 600 x 900 pixels (or any 2:3 size) is the optimal size for a Pin.


Pins are organized into columns, so vertical Pins take up more space and tend to stand out more on our platform. The ideal aspect ratio for a vertical Pin is 2:3 — 600px wide x 900px high.

Square images — 600px wide x 600px high — can work well, too. Pins longer than 1260px high will get cut off, and people will only see the entirety of the Pin when they tap it for a closeup. Pinterest optimizes Pins that fit within these preferred aspect ratios.”

6. Tumblr image post sizes

First thing’s first, get your Tumblr profile on point! If you’re not a coder, using the Tumblr template for your profile is fine. Your profile pic is only small — 128 x 128 pixels is the perfect size. Your header image, on the other hand, is huge, so avoid pixellated images on desktop and mobile by going big: 3000 x 1055 pixels is the recommended size.


The optimal size for a Tumblr graphic is 540 x 810 pixels, although other sizes are acceptable and work very well on the platform too.

7. YouTube image sizes

OK, so these ones aren’t strictly post sizes, but they’ll probably come in handy if you’re ever creating a video to upload to YouTube. Recommended video dimensions for YouTube are 1920 x 1080 pixels.


The rest of these are the standard image sizes you need to know for sprucing up your channel:

  • Thumbnail 1280 x 720 pixels
  • Channel art 2560 x 1440 pixels
  • Channel icon 800 x 800 pixels


8. Snapchat image post sizes

This one’s pretty simple. Most users won’t ever wonder what the perfect size is because they’re taking photos with their camera and sending them immediately. But for those who like to plan ahead… A snap should measure 1080 x 1920 pixels whether it’s a Story or a privately sent pic.

9. Google + image post sizes

A Google + profile pic should be 250 x 250 pixels and the cover image should be 1080 x 608 pixels for the best display on desktop and mobile.


Shared image on Google + is displayed on desktop as 497 x 373 pixels, so try not to share anything smaller to avoid degrading the quality of your share.


10. Twitch image sizes

If you’re thinking of exploring the fun filled world of Twitch, you need to know the basics. Your profile pic needs to be 800 x 800 pixels, and your cover image 380 x 1200 pixels. Standard video dimensions are the same as YouTube’s: 1920 x 1080 pixels, and the thumbnail will display as 1280 x 720 pixels. Here are some example images to get your creative juices flowing!




11. TikTok video sizes

If you want to jump on the social network that is rockin’ the world in 2020, it’s important to ensure that your videos are correctly optimized for TikTok. That way, viewers will see your videos exactly as you want them to be seen.

Here are all the specificities you need to know: TikTok video dimensions should be 1080×1920, and, even though vertical videos are best, horizontal video is also allowed. Your video can be up to 287.6MB in size for iOS and 72MB on Android (for ads, it can be up to 500MB).
