What is the best blog image size in WordPress?

Best blog image size in WordPress

📚 This post is part of my business blogging guide.


Here’s how to get the image sizing right on your website, along with some free tools and resources to help you find and use the right images.

Introduction

If you write a blog, the most important image is the one that’s most often splashed across the top of the page – the so-called ‘hero’ image. I’ve got one of these at the top of this post, for example.

When your blogs are shared on social platforms such as Facebook, Twitter, LinkedIn and Google+, it’s good for them to include the hero image, as that makes the content more appealing than a plain and boring link.

You can make sure your social shares include an image by using the Yoast SEO plug-in, which is covered below.

But what about the hero image itself? How big should that be?

That’s what the next bit’s about.

Hero image sizes and safe area dimensions

Your hero image should be this size:

Hero image size

1200×630 pixels

You should keep your important content away from the edges. Otherwise, you might see that parts of the image are clipped off when the content is shared on social media.

Safe area inside hero images

1110×610 pixels

Here’s what that looks like:

Feel free to save the image and use it for comparison with your own images.

If you know how to use Photoshop, you can download this PSD original instead.

Once you’ve got the image you want, you can insert it at the top of your post or, if your blog theme supports it, set it as a ‘Featured Image’ for the post.

Which image sizes work best on social media?

If you want to post images directly on social media, here are some sample sizes that work well:

  • LinkedIn profile banner: 1584×396 pixels
  • LinkedIn image posts: 1024×576 pixels
  • LinkedIn article covers: 744×400 pixels
  • Twitter profile banner: 1500×500 pixels
  • Twitter image posts: 1024×576 pixels
  • Facebook image posts: 1200×630 pixels
  • Instagram square: 1080×1080 pixels
  • Instagram vertical: 1080×1350 pixels
  • Instagram horizontal: 1080×566 pixels

More about Facebook and Instagram images

Instagram and Facebook work well with square images, e.g. 1080×1080 pixels.

But … both platforms support landscape images (e.g. 1024×576 pixels), and things can get a little messy because of display adjustments that are based on the orientation of your device.

Take a look at this Buffer post for more on this.

Including hero images when sharing links on social media

If you use WordPress, you can include the right hero image whenever you post a blog link on social media.

To do that, install the Yoast SEO plug-in on your WordPress website. This will add an extra panel at the bottom of your WordPress editor.

As well as its other search engine optimisation (SEO) features, the Yoast plug-in lets you nominate the image you want to associate with each blog post, so that social shares include that image with the link.

The free version of Yoast doesn’t display a preview of the image in your WordPress editor, but that doesn’t matter if you’ve followed the sizing guidelines above.

Below is a screenshot of the premium version of Yoast, which does display a preview:

How can I create images for free?

If you want to create your own images for social media and your blogs, check out these free services:

  • Canva – probably the world’s most popular image-creation tool.
  • Pablo – perhaps not as powerful as Canva, but it’s easier to use (and it’s made by Buffer, who are cool).
  • Fotor – not one I’ve tried myself but looks good and has been recommended to me by a colleague.

How can I make my images load faster?

It’s important to optimise your images to reduce their file size. The smaller the files, the quicker the loading time, which means a better user experience for your visitors.

Try these free image-optimisation tools. You won’t notice any difference in the image quality, but the file sizes will decrease.

  • ImageOptim – macOS.
  • PNGGauntlet – Windows.
  • TinyPNG – WordPress and Photoshop plugin.

    Let’s wrap up

    Good images will help your blog posts stand out, and using dimensions of 1200×630 pixels for your hero images means that your visuals will work well when your posts are shared on most social platforms.

    If you use WordPress, make sure to add the Yoast SEO plug-in to make it easy to associate your social posts with your hero images.

    Tools such as Canva and Pablo can help you produce images at the right dimensions for all social platforms, so give them a whirl and see whether they help you get your content noticed.
