How to Change Your Featured Image Size in WordPress

WordPress is a versatile content management system that allows users to customize various aspects of their website, including the size of featured images. Featured images play a crucial role in grabbing the attention of visitors and enhancing the overall visual appeal of your WordPress site. In this article, we will explore the steps to change your featured image size in WordPress, ensuring that your images are perfectly optimized for your website’s design and layout.


When creating a WordPress website, you may find that the default featured image size doesn’t align with your design preferences or specific theme requirements. Fortunately, WordPress provides several methods to change the featured image size, allowing you to have full control over the visual representation of your content.

Before we delve into changing the featured image size, let’s quickly understand what featured images are and their significance in WordPress. Featured images, also known as post thumbnails, are representative images associated with your blog posts or pages. These images are often displayed prominently on your website, serving as visual representations of your content.

Selecting the appropriate featured image size is crucial for maintaining a visually appealing website and ensuring optimal user experience. A well-sized featured image can enhance the overall aesthetics of your site, improve page loading speed, and contribute to better search engine optimization (SEO) by providing relevant visual cues for search engines.

Before proceeding with changing the featured image size, it’s important to determine the current dimensions of your featured images. To do this, navigate to your WordPress dashboard and go to the Media Library. Locate a previously uploaded featured image and view its details to identify its size.

Many WordPress themes come with built-in options to adjust the featured image size. These options can be found within the theme settings or the customizer. By exploring the theme settings or customizer, you can locate the section dedicated to featured images and modify the size according to your preferences.

In case your theme doesn’t offer native options to change the featured image size, you can rely on plugins to accomplish this task. WordPress provides a wide range of plugins specifically designed for image manipulation and customization. Search for image optimization or media management plugins, and choose one that offers the flexibility to resize your featured images.

Now, let’s walk through a step-by-step guide to changing the featured image size in WordPress, irrespective of whether you’re using a theme or a plugin.

Step 1: Choosing the Right Theme or Plugin

Begin by selecting a WordPress theme that provides options to adjust the featured image size or install a suitable plugin if your current theme lacks this functionality.

Step 2: Installing and Activating the Theme or Plugin

Once you’ve chosen the theme or plugin, install it on your WordPress site and activate it. Ensure that the theme or plugin is compatible with your WordPress version to avoid any compatibility issues.

Access the settings or customization options for the chosen theme or plugin. Look for the section dedicated to featured images and locate the settings related to image size. Depending on the theme or plugin, you may have options to enter specific dimensions or choose from predefined sizes.

Navigate to the post or page where you want to change the featured image size. Click on the “Set Featured Image” button and either upload a new image or choose an existing one from the media library. Follow the instructions provided by the theme or plugin to set the featured image.

Step 5: Previewing and Publishing the Changes

After configuring the featured image settings and setting a new featured image, preview your post or page to ensure that the changes are applied correctly. If everything looks satisfactory, save or publish the changes to make them visible on your live site.

While changing the featured image size, it’s essential to consider best practices to ensure optimal results. Here are some important considerations to bear in memory:

  • Be mindful of aspect ratios: Maintain the original aspect ratio of your images to prevent distortion and preserve image quality.
  • Consider responsive design: Choose image sizes that adapt well to different screen sizes and devices, ensuring a consistent user experience across platforms.
  • Balance image quality and page loading speed: Optimize your images for the web to strike a balance between high-quality visuals and quick loading times.
  • Keep SEO in mind: Ensure that your featured image sizes align with SEO best practices, such as adding descriptive alt tags and optimizing image file names.

In addition to changing the featured image size, optimizing your images for SEO can significantly impact your website’s visibility in search engine results. Use descriptive file names, add alt tags that accurately describe the image, and compress your images without compromising quality to improve your SEO efforts.


Changing the featured image size in WordPress is a simple yet powerful customization option that allows you to enhance the visual impact of your website. By following the step-by-step guide and considering best practices, you can ensure that your featured images are perfectly sized and optimized for an engaging user experience.
