Best Featured Image Size In WordPress


It’s crucial to use the proper image sizes for WordPress for two reasons.

  1. You want your photos to look nice.
  2. Images should load quickly without slowing down your website.

Everything you need to know about WordPress image sizes is covered in this comprehensive guide.

A Detail of WordPress Image Sizes

When it comes to WordPress, image size matters.

Incorrect picture sizing can result in images that are jumbled, hazy, or load slowly, which will impact your website’s speed as well as the overall WordPress web design and SEO.

Fortunately, WordPress assists you in avoiding these issues.

Image Processing In WordPress (Default Sizes)

WordPress automatically generates four different image sizes whenever you upload an image:

  • Size of thumbnail (150 x 150 pixels)
  • Medium-sized (up to 300 x 300 pixels at most)
  • Huge dimensions (up to 1024 x 1024 pixels)
  • Full size (the uploaded image’s initial size)

WordPress takes care of this, saving you from constantly having to manually resize images and making sure the ideal size is chosen for each place on your website.

A blog post’s thumbnail image and its header image, for instance, will have different file sizes.

Editing The Default Image Sizes In WordPress

You can upload custom image sizes to suit your needs in addition to the default image sizes.

Here’s how to do it:

  1. Access your WordPress Admin Area.
  2. Select the Settings – Media option.
  3. Modify the default image settings in the Media Settings to suit your tastes.
  4. Click Save Changes.

The ideal picture sizes for WordPress are as follows:

  • Header image size (banner size 1048 x 250 pixels)
  • Featured image size (landscape 1200 x 900 pixels)

  • WordPress background image size (1920 x 1080 pixels)
  • Logo image size (200 x 100 pixels)
  • Thumbnail image size (150 x 150 pixels)

WordPress Image File Sizes Optimization

The size of each picture file should be taken into consideration when uploading images to WordPress. Any image with a big file size will negatively impact your website’s speed, which will ultimately impact user experience and possibly lead to users “bubbling” off of your site.

Having pictures that are larger than necessary serves no purpose.

With the exception of large photos, WordPress image sizes should generally not exceed 150 kb.

Image Compression

When it comes to the success of your website, website speed is crucial.

Prior to uploading to WordPress, you can increase performance without compromising the quality of your images by compressing them (it doesn’t resize images).

You should apply image compression to every image you upload to your website; otherwise, the performance of your site will suffer.

Image Formats

WordPress supports a wide range of picture formats.

Also, there are benefits and drawbacks to each format in terms of the ratio of file size to image quality.

Expert advice: Select an image format that strikes a good balance between speed and quality.

Selecting The Right Image Format

Pick PNG for graphics and JPEG for photos.


The smallest file size for photos is JPEG, or joint photographic experts group, which supports 16 million colors. When you use JPEG for your photos, the image will load more quickly and look more vibrant.


Although PNG is less color-supporting than JPEG, it allows for image transparency and is increasingly used as the standard format for logos and other website elements.


256 colors, transparency, and animation are supported by the Graphics Interchange Format (GIF).


Q1: Can I change the default Featured Image size in WordPress?

Yes, you can adjust the default featured image size by navigating to Settings > Media in your WordPress dashboard. However, keep in mind that changing the default size may affect the layout and appearance of your theme, so proceed with caution and test your changes thoroughly.

Q2: What happens if my image doesn’t match the chosen size?

Depending on your theme settings, WordPress may automatically resize your image to fit the chosen dimensions. This can lead to unwanted stretching or cropping, so it’s best to choose an image size that closely matches your original image aspect ratio to avoid distortion.

Q3: How can I ensure my Featured Images are optimized for SEO?

Utilize descriptive Alt Text and Titles that accurately describe your image content. Additionally, compress your images to reduce file size without sacrificing quality, as faster loading times improve SEO performance.

Q4: Are there plugins to help me manage Featured Images?

Yes, several plugins like “Easy Thumbnails” and “Featured Image from Post Content” can help you manage featured images more efficiently. They can automate thumbnail generation, create custom image sizes, and even optimize your images for performance and SEO.


The optimal dimensions for a featured image on WordPress are 1200 x 628 pixels. These particular measurements also typically work with the majority of WordPress blog themes that are pre-designed. With the right size and a dash of visual magic, your featured images will become more than just placeholders – they’ll become gateways to engagement, driving clicks, boosting conversions, and transforming your website into a captivating hub of activity. So, unleash your inner image maestro, choose your canvas wisely, and paint your way to online success!
