It’s no secret that images convert better than text that’s why microblogging is taking over. Words are at their most evocative when they conjure images in the mind’s eye, but Internet users have notoriously short attention spans. You can’t count on them to take the time to read evocative copy. Images, therefore, must serve as a lure that warms a prospect to what you have to say.
Unfortunately, the most popular social media networks have wildly different requirements when it comes to uploading images. You will always have to double-check the height and width of your images before you post, but with this guide, you’ll at least know what the optimal resolutions are for each network.
Keep this in mind, though: you should always take your images at the highest resolution possible. Social networks will automatically scale your images down, so if you start with a low-resolution source, the end result will look even worse.
The Facebook cover photo is a major attention-grabber, so you absolutely want to get this one right. The image should be at least 851×315 pixels. Profile photos should be at least 180×180, although Facebook will automatically size them down to 160×160.
Link images are best at 1200×627, and Facebook will scale them down to 403×210 on PCs and 560×292 on mobile devices. Post images, meanwhile, should be at least 1200×1200, and they’ll display at 403×403 on the PC and 560×560 on mobile devices. Facebook accepts the JPEG, BMP, PNG, TIFF, and PNG formats.
Twitter supports images as long as they’re hosted on pic.twitter.com and are displayed inline. Your Twitter profile picture should be 400×400, and your cover picture should be 1500×500. Keep post images at 880×440—an aspect ratio of 2:1—and note that these images cannot exceed 3 MB or 1040×512.
Twitter supports the following formats: JPEG, PNG, and GIF. Note that the GIF format supports animation, which is a great way to grab your followers’ attention. Animated GIFs are a series of individual photos in sequence which loop endlessly.
Google+ now has more than 1.5 billion users, and the network boasts over 200 million mobile users. Though it remains less popular than Facebook, there’s no doubt that Google is doing all it can to push its network. Here is how to post images.
Your profile pic should be 250×250, and it will display as a circle. This means that some automatic cropping will occur, so make sure that the individual’s face is centered in the image. Post images must be at an aspect ratio of 1:1, and the optimal size is 620×620.
Your cover photo should be 1080×608. You’ll want to crop 140px from either side because many mobile devices don’t display these pixels anyway. Like Twitter, you can use animated GIFs on Google+.
The network for professionals that requires no introduction, LinkedIn is not exactly photo-friendly. Infographics and other long visuals get cut off, so if you plan on posting these, consider cropping them to create a teaser. Your LinkedIn company logo should come in at 100×60, while your profile picture can be 200×200.
Your cover photo should be 646×220, while your link posts can be any size but will scale down to a stingy 180×110. Your background post can be as large as 1400×425, but note that this is a premium feature.
Pinterest, the image playground, can be a consistent traffic source for companies with products that appeal to its mostly female user base. Note that “pins” on Pinterest are previews. When a user clicks them, a larger version of the image appears.
Pins should be at least 736 pixels wide, and the height will scale automatically. Your profile pic should be at least 600×600 pixels. Note that your board cover image will be displayed at 216×146, and is scaled down from the size of the pin you decide to feature. Similarly, your pin cover images are scaled down to 236px in the same fashion.
