Are you a WordPress newbie who’s confused about the thumbnail sizes? Or are you a seasoned user who’s never given it much thought? Fear not, this definitive guide on WordPress thumbnail sizes is here to help you all!
What is a Thumbnail in WordPress?
Before we dive into the various thumbnail sizes, let’s first define what a thumbnail is in WordPress. Simply put, a thumbnail is a smaller version of an image that is used as a preview or teaser. These thumbnails are usually displayed in post lists, galleries, and widgets.
Why are Thumbnails Used?
Although there are many uses for thumbnails, enhancing the user experience is the most crucial one. Consider if you would want to browse through a lengthy list of posts with only text or a list of aesthetically appealing posts with thumbnails. I already know which one I’d pick!
Thumbnails not only enhance user experience but also hasten the loading time of your website. WordPress automatically creates thumbnails when a post or page is loaded. WordPress creates three thumbnails by default for each picture that is submitted to your website. These thumbnails are utilized in a variety of areas of your website, including widgets, galleries, and post lists.
Various Thumbnail Sizes are Available on WordPress by Default
Let’s look at all of the thumbnail sizes that are accessible on WordPress by default, now that we understand what thumbnails are and why they’re crucial. WordPress creates thumbnails in three sizes by default: thumbnail, medium, and large. This is a comparison of each size:
1. Thumbnail Size (150 x 150px)
The “thumbnail” size is the smallest size of thumbnail available in WordPress. It’s used in post lists, widgets, and galleries. The dimensions are 150px x 150px. This size is perfect for displaying a small preview of an image.
2. Medium Size (300 x 300px)
The medium size is a slightly larger version of the thumbnail size. It’s used in post lists, widgets, and galleries. The dimensions of the medium size are 300px x 300px. This size is perfect for displaying a larger preview of an image.
3. Large Size (1024 x 1024px)
The largest size of thumbnail available in WordPress by default. It’s used in single posts and pages. The dimensions of the large size are 1024px x 1024px. This size is perfect for displaying the full-size image.
In addition to these three sizes, you can also create custom thumbnail sizes using plugins or by adding code to your theme’s functions.php file.
Custom Thumbnail Sizes
You may add code to the functions.php file of your theme to add custom thumbnail sizes if you want more control over their dimensions. By doing this, you may specify the precise proportions of your thumbnails rather than depending simply on the sizes that WordPress generates by default.
Easy Picture Sizes and other plugins like them make it simple to generate custom sizes without knowing any code, but adding code to the functions.php section of your theme provides you access to more sophisticated customization possibilities. Here are a few popular plugins that you can use to create custom thumbnail sizes:
A well-liked plugin called Regenerate Thumbnails enables you to renew your thumbnails after altering their sizes. This is helpful if you’ve modified your theme’s functions.php file’s thumbnail sizes or if you’ve installed a plugin that generates unique thumbnail sizes.

Tips for choosing the perfect Thumbnail Size
Before choosing a thumbnail, you should keep in mind a few things –
Consider the Layout of Your Website
The size of your thumbnails should be based on the layout of your website. If your design is minimalist with lots of white space, consider using larger thumbnails. Conversely, if your layout is busy, smaller thumbnails may work better.
Think About the Purpose of Your Thumbnails
Consider the purpose of your thumbnails – are they just to provide a visual preview of your content or are they meant to encourage clicks? If you’re looking to encourage clicks, larger thumbnails may be more effective.
Keep Image Size in Mind
When selecting thumbnail sizes, take your original image’s size into account. Use bigger thumbnails if your photographs are huge to prevent pixelation or distortion. Smaller thumbnail sizes can work better if your photographs are smaller.
Test and Adjust
Testing and modifying can help you find the best thumbnail sizes for your website. Try out different sizes to find which works best for your content and layout. By using this technique, you may choose, based on your tastes, the ideal thumbnail sizes for your website. It is a fantastic technique to figure out what functions well for your website and what does not.
If you are getting blank thumbnails, you should make sure to fix them.
