Best WordPress Featured Image Size & Post Thumbnail Tips

Best WordPress Featured Image Sizes, Are you wondering what size your featured image should be on WordPress? Or how to create a post thumbnail for your blog posts? This is the article for you!

Image sizes are important because they can affect how many visitors see and click through to your site. Images that are too small will show up blurry, while images that are too large may not look crisp on smaller screens or if someone has their browser window set to a smaller width. The right balance of quality and file size is key. If possible, shoot for an image resolution of at least 600 pixels wide by 400 pixels high (or higher). A good rule of thumb is 200KB per photo–shoot for under 1MB total when uploading multiple photos in one gallery.

Post Thumbnails are small versions of your featured images that appear on the front end of your blog posts. They are typically located under the title and feature an aspect ratio of 4:3 or 16:9 (widescreen). Post Thumbnails will help viewers see what the post is about before they click to read it.

What Size Should My Featured Image Be?

Featured images are the large, round images that appear at the top of a blog post. When a person clicks to read a blog post on your site, the featured image will be one of the first things they see while reading. A good rule of thumb is to have an image resolution that’s twice as big as your display resolution for your site. For example, if you’re using a 1280px wide display, your featured images should be at least 2560px wide.

Do I Need to Use a Post Thumbnail?

If you’re just starting out on your blog, then it’s highly recommended that you use post thumbnails for your posts. They can help create a strong visual appeal on your site and help your visitors know what the post is about before they click through to read more.

The default size for featured images is 150px by 312px, but you can easily change this in your Theme options panel:

You’ll notice that if you’re using the “Twenty Eleven” theme as a starter blog, your featured image dimensions are much smaller – 150px by 150px. This is because the Twenty Eleven theme was designed for an 800×600 screen resolution and the default size of a featured image reflects this.
