Recently here at Passle we've been working on getting posts without images to display something nice on social media (Facebook, Twitter shares etc.).
This is a difficult issue because there is no default social media image size. Luckily someone has created a cheat sheet so you can decide for yourself what size each image you put on social media should be. It's a couple of years old but should still be relevant.
If you're still struggling to find a good size we recommend the following:
- A landscape image should be approx. 1024 x 512 px
- A portrait image should be approx. 800 x 1200 px
If you’ve been active on social media for a while, or you just made your accounts, you’ll realize that when it comes social media, visual content and social media go together like French fries and dip sauce, and all comes down to the last pixel. Social networks are constantly adding up more features, visual elements, and it seems like every day when you wake up, you see a new element or iteration being made to the social networks you are active, making you go back and figure out the right size of cover images, post images and align your campaign according to the latest set of changes.
