Choosing the right image size for your blog’s featured images can make a significant difference in your website’s appearance, performance, and user engagement. If you’re using the popular Divi theme for WordPress, understanding recommended image sizes is especially important because Divi’s responsive design and modules rely on specific dimensions to display images optimally across devices.

Why Featured Image Size Matters in Divi

The featured image is more than just decoration—it’s the face of your content. This image appears in your blog feed, on single post pages, and in module layouts like blog grids and sliders. When properly sized, featured images enhance visual appeal and reduce layout issues such as image distortion, cropping, or slow loading times.

Recommended Featured Image Size for Divi Blog Posts

While Divi is flexible and can adjust to a range of sizes, there are recommended dimensions that ensure your images look crisp and load efficiently. A good rule of thumb is to use:

  • Width: 1080 pixels
  • Height: 675 pixels

This 16:10 aspect ratio is ideal for most blog layouts in Divi. It provides a wide enough frame to look great on desktops, tablets, and mobile devices. If you’re using full-width layouts or blog grid modules, this size gives your content a polished, uniform appearance.

Divi Blog Module Image Sizes

The Divi Blog Module offers different layouts that determine how your featured images appear. Here’s how size impacts each layout:

  • Grid Layout: Featured images in this layout are typically displayed as squares or rectangles. A square image like 600 x 600 pixels works well but may crop unless properly centered. A safe default is 400 x 250 pixels for horizontal thumbnails.
  • Fullwidth Layout: This layout benefits from larger, high-resolution images. Stick to the recommended 1080 x 675 pixels or even consider 1200 x 800 pixels if you want greater clarity on larger screens.

Always ensure that your images are optimized for the web using tools like TinyPNG or ImageOptim to maintain fast site speeds.

Customizing Image Sizes in Divi

If the default sizing isn’t meeting your needs, Divi allows you to customize image dimensions through the WordPress Customizer or by using child themes. You can specify custom thumbnail sizes in your functions.php file using a function like:

add_image_size( 'custom-blog-thumb', 1080, 675, true );

This tells WordPress to generate a custom thumbnail size of 1080×675 pixels with hard cropping enabled, ideal for consistent-looking blog featured images.

Responsive Design Considerations

Because Divi is built with responsiveness in mind, your featured images should also be prepared for various screen sizes:

  • Use high-resolution images without excessively large file sizes.
  • Test image appearance on mobile, tablet, and desktop views in the Divi Builder.
  • Avoid tall, narrow images for featured use, as they may appear awkward in landscape-oriented layouts.

Tips for Creating Stunning Featured Images

In addition to using the right dimensions, consider these tips to make your featured images stand out:

  • Use text overlays sparingly to highlight titles or hooks.
  • Maintain consistent branding with fonts, colors, and styles.
  • Choose images with a strong focal point—this ensures the subject remains visible even if cropping occurs.

Using graphic tools like Canva or Adobe Express can help you create eye-catching visuals with the right dimensions from the start.

Conclusion

By following the recommended featured image sizes for Divi blog posts—particularly 1080 x 675 pixels—you ensure your content looks professional, loads quickly, and adapts seamlessly across devices. Whether you’re using the built-in blog module or a third-party Divi plugin, getting your image dimensions right is a key step toward building a beautiful and effective WordPress blog.
