Size of social media posts

It’s important to check because they change so when people ask me what banner sizes to use I guide them to sites that do their homework and keep things current.

So let’s start with a B2B basic: LinkedIn. Different rules depending on whether you are a person or a company.

If you are an individual: your profile picture should be 400 x 400 and should look like you – like you look today when you go to work – a little formal. Your background header image should be 1584 x 396 and should be fairly clean – you don’t want it to detract from your face. A banner bearing your logo or tagline works a treat.

If you are a company you should use your logo as your profile picture 300 x 300 and use a plain company cover image 1536 x 768. As Brandwatch points out, it’s odd as it will be mostly covered so keep it plain and don’t think about it for too long.

Posting on LinkedIn: 1200 x 1200 posts; videos min 256 x 144 px – 4096 x 2304 px max. Videos can be ten minutes but I recommend 2 1/2 minutes unless you are Madonna, Bill Gates or Meghan Markle.

On to Twitter: again profile picture 400 x 400 px. Use your LinkedIn profile if you use both for business for continuity. Your profile photo can be bland or give it some contrast and should be 1500 x 500 px.

Twitter posts demand an image: your post gets 150% more attention if you use an image. It’s not worth not adding one. 1024 x 512 px. Any videos should be SHORT. Twitter allows for 140 seconds but who watches a video for longer than 2 minutes? Keep it to 30 seconds and subtitle it. Size-wise pixel-wise use 720 x 720 (square), 1280 x 720 (landscape), 720 x 1280 (portrait).

I’ve started exploring Tik Tok. The best thing about working in communication is you’re always down with the kids. Profile picture 200 x 200; video size 1080 x 1920 px and keep your videos to 15 seconds. You can include links in your posts.

If you’re promoting an event, you’re likely to be using Eventbrite. Your event image will need to be 2160 x 1080 px JPEG, BMP, PNG or GIF no larger than 10 MB.

Facebook used to have different rules for business pages but not anymore. This means profile image 180 x 180 px, cover photo 820 x 312 630 px. I’m use FB events and run Facebook Lives and find I tend to have everything they want. I’ve been using standard high res photos for my event covers though official guidelines say 1920 x 1080 px. I’m loving video content – you can have up to 250 minutes – 240! Subtitle your videos if you can: every home and café is now a workspace:) Full guidelines from Facebook are here.
