The algorithm and your followers will thank you for having the correct post sizes in your social media posts.

But finding that information isn’t as easy as it sounds, unless you have a complete, up-to-date guide to all the sizes, across all social networks, to help you.

Here’s a look at all the dimensions in this article so that a clipped title in your design, or lack of engagement, won’t be your worry when you run your social media strategy in 2023.

Why Do You Need This Guide?

Here’s a quick look at the importance of using the right dimensions in your social media posts:

1. Consistency: Not only is it important to have consistency, for example, in your Instagram feed, but it is also important to have consistency across the various social networks where you may be present. This way, your brand gains credibility and familiarity with the audience.

2. Visual Impact: Small, distorted, blurry, and low-resolution images are the perfect cocktail to decrease your brand’s trust and engagement.

3. User Experience: If you want to stay on the positive side of the algorithm, generate more traffic, and increase the ease with which the audience can find information, then having the right measures in place is essential.

4. Search Optimization: Putting images in the right sizes can also improve your position in social media searches. If you think about a social network like Pinterest, optimizing your posts increases the chance of appearing at the top.

Post sizes for Facebook

Facebook is still the social network with the most users in the world (in 2023) and supports a variety of content formats, including stories, which have been gaining more and more relevance.

This social network is becoming more and more visual, and with that, the importance of having the right dimensions increases. Make sure your dimensions match those in the image.

Facebook Tips

  • Always use images with the highest resolution possible and that are relevant to the audience you want to reach.
  • The file type when uploading should be: JPG or PNG.
  • Facebook allows you to identify (within the photo) people who are in it, or who are relevant. Use this to your advantage.
  • A good picture requires a good description, so invest time in good text. If you’re out of ideas, use artificial intelligence tools to help you.

Post size for Instagram

As a platform, Instagram focuses on visual content, and this is where the social media manager can explore their creativity with the different formats that this social network supports.

Perhaps the most popular right now is the Reels format. Yes, that vertical, short video format, is similar to TikTok. But despite that, you have a number of other formats to communicate your message.

Here are the formats to look out for when posting on Instagram.

Instagram Tips

  • Instagram is known for the ability to use filters that improve the appeal and consistency of your images, so use them!
  • It is important to use hashtags. Use ones that have relevance to the topic and a reasonable number of posts (usually over 5000).
  • To increase the chances of your photo being discovered, add location.
  • In Reels, Meta recommends leaving about 14% (250 pixels) of the top and 20% (340 pixels) of the bottom of the image without text, logos, or other creative elements.

Post dimensions for TikTok

TikTok has over a billion active users every month, making it one of the most popular social networks in the world.

The format of this social network requires you to make a good first impression, otherwise, you run the risk of the consumer giving a “swipe down”, and your chance to communicate with him is over.

TikTok’s big new feature is horizontal video support. Previously, the app placed black borders so that horizontal video could fit into the 9:16 format. However, now, although the first appearance in the horizontal video feed will still have the black bars, the user has the option to put it on full screen.

Tips for TikTok

  • Use high-quality videos or images that are dynamic and grab the audience’s attention within a few seconds (3-5 seconds).
  • Use TikTok’s editing tools to make your videos and images more appealing.
  • Similar to Instagram, use trending hashtags and sounds to make your videos easier to discover.

Post dimensions for Twitter

Twitter is a platform for sharing news and messages, with a maximum limit of 280 characters. At least as far as free users are concerned.

As of February 29, 2023, Twitter Blue users are allowed up to 4000 characters per Tweet.

If you want to perform better in your Tweet, besides buying the Twitter Blue subscription (thanks Elon Musk), using an image will give you a big engagement boost.

Twitter Tips

  • On Twitter, you can use in addition to images, GIFs to increase the impact your image has on the reader.
  • Hashtags are also important, as they can be a way to get in on Twitter trends.
  • The use of infographics on this platform is also common. Consider using them to communicate, for example, statistics.

Post Dimensions for LinkedIn

Linking images on LinkedIn, similar to Twitter, also increases engagement levels. Whether on LinkedIn for business or in your personal account, use images to increase the impact of your message.

Another essential aspect of LinkedIn is your profile picture. This is because the goal of this social network is to provide a space for users to not only find content that makes them more productive and professional but to establish relevant professional relationships.

That said, it is essential to have a good-quality image for both you and your company.

LinkedIn Tips

  • Use images to promote your personal brand. Consider using a profile picture with a flat background, where you are well-lit and facing the camera.
  • Another possible format to use on LinkedIn is PDF posting. If you choose this medium, whether to upload a case study, ensure the quality of the images in that document.

Post dimensions for Youtube

If you want to use video marketing, then Youtube is probably a good option for your strategy.

One of the most important aspects of Youtube, besides the video itself, is the thumbnail. It is important to emphasize this point, as this is one of the first things your audience will see (along with the title).

Having an image with high-quality, personalized, and well-positioned information is essential for the success of your video.

Youtube Tips

  • In your thumbnail, it is important not to put too much text, and it is advised not to use more than 6 words in your image.
  • Maintain consistency between your profile picture and the cover image of your channel.
  • Depending on your audience and the purpose of the content, it is also a common practice for Youtuber to put an image of their own face, preferably expressive (happiness, sadness…), as this will increase the click-through rate.

Post dimensions for Pinterest

Pinterest is a social network that relies entirely on the use of images with the particularity that users can “collect images”. This is done through the “pin” feature, which lets users save the images they want in various folders.

If you enter this application through other social networks, such as Facebook or Twitter, your profile picture will automatically be set to the one you have on those platforms.

Note that if you want to use a new profile picture on Pinterest, you will need to upload it in the dimensions mentioned below.

Pinterest Tips

  • Consider using images vertically, being that most content consumption on this social network is done in that orientation.
  • Include your logo in your posts, but keep it unobtrusive and avoid the bottom right corner, as it will be covered thereby Pinterest’s product icons.
  • Show, don’t tell. Don’t rely on audio as some users view posts with the sound off.
