What Size Is a Featured Photo?

When creating content for your WordPress site, selecting the appropriate size for your featured images is crucial. These images not only catch the eye but also significantly affect your site’s SEO and loading times. In this guide, we’ll explore how to optimise your featured image size for both user engagement and search engine rankings.

Understanding Featured Images in WordPress

What Is the Standard Featured Image in WordPress?

The standard featured image size can vary depending on the theme you use. Generally, a size of 1200×628 pixels works well as it is large enough to be engaging without being too heavy on load times. This dimension suits a variety of devices and orientations, making it a versatile choice for bloggers and webmasters.

  • Compress Images: Use tools like Adobe Photoshop or free online services to reduce file size without losing quality. This improves load times and SEO.
