How to share different image sizes on social media with Nelio Content

Social networks are the perfect place to promote your content. The audience is there, so all you need to do is connect with them and invite them to visit your website. This is not easy, but Nelio Content helps you share messages on social networks without the hassle and maximizing your resources.

When filling the timeline of social messages to promote your content on social networks with Nelio Content, you will create several types of messages, and some of them will share the featured image of your posts. The problem here is that each social network recommends using a different image size, so your featured image will not look the same when shared on Twitter as it does on Facebook or Instagram.

Even though the image won’t look bad anyway (unless you use very strange dimensions), if you want to achieve perfection you must use different versions of the same image to share in each social network, each with a different size. This way, the image is shared with a perfect size for each network, and your followers will enjoy a better user experience.

Let’s see how we can achieve this by simply using the Custom Social Images panel of Nelio Content.

Recommended Image Sizes For Each Social Network

Before we start, let’s see which image sizes are recommended in each social network. Keep in mind that social networks are in constant evolution and these sizes may no longer be valid in the future. But at the time of writing these lines, the sizes are as follows:

• X/Twitter: The recommended size are 1600 x 900 pixels, 1080 x 1080px, and 1080 x 1350px.
• Facebook: The recommended size for the images we share on Facebook is 1200×630 pixels high. However, in the news feed that your audiences see, these images will be shown with a maximum of 470 pixels wide (scaling the original image while keeping the same proportion).
• LinkedIn: The optimal dimensions for a LinkedIn post are 1200 x 628 pixels to be displayed optimally. Also images should have less than 36152320 pixels in JPG, GIF, and PNG formats.
• Instagram: Square images allow a side size of 1080 pixels, which will be reduced to 612 pixels and displayed in the feed with 510 pixels. You can also choose to use landscape images of 1080×566 pixels or portrait images of 1080×1350 pixels. In both cases they will also be scaled down when shown in your followers’ feed.
• Pinterest: When you add a pin to your board, it is important to remember that Pinterest sets a limit on the width of the image but not on the height. This gives you the opportunity to add a squared photo or one that is even larger in height. Images appear with a maximum width of 236 pixels. Aspect ratios of 2:3 or 1:3.5 are recommended.
• Tumblr: Images in Tumblr have a maximum size of 1280×1920 pixels, which are displayed in the feed downscaled to 500×750 pixels.
• Bluesky: Images should have 1200×675 pixels. Bluesky crops images differently across devices, usually to a 16:9 aspect ratio. Center key content to avoid it being cropped out in previews.
• Mastodon: Images should have 1200×675 pixels. Maintain a 16:9 aspect ratio and avoid placing key content near the edges, as Mastodon crops previews. Keep text and logos centered to ensure visibility in the feed.

In addition to the previous recommendations, most social networks have restrictions on the maximum image you size can use. Given the above dimensions, you should try to keep the images you share on social networks below 250Kb in weight. For this purpose, websites like compressjpeg.com make it very easy for you to compress the images without losing (too much) quality.

Custom Social Images

Now that you know the image sizes you should use, let’s see how to tell Nelio Content which specific image to use when sharing messages on social networks.

When editing a post, press the Nelio Content Social plugin button in the top toolbar. A panel named Custom Social Images appears in the sidebar of the block editor where you can indicate (just like you do with the featured image) which image you want to publish on each social network (see image below).

From now on, you can have different images to share in your social messages. Nelio Content will automatically take the alternative image if you selected it and create the messages automatically taking these images into account instead of the default featured image.

If you’re an image lover, you have no excuse for not using Nelio Content to automatically share your content on social networks. With this you will be able to specify an image for each social network with the size you want. Adapt your content better to the particularities of each network!
