OG:Image Sizes
How content appears on social media platforms is an important factor that directly affects engagement rates in the digital world. This is where the Open Graph (OG) protocol comes into play. Developed by Facebook and later adopted by many other social media platforms, this protocol helps determine how websites appear when their content is shared on social media.
The OG:Image tag allows you to specify a custom preview image for shared links. Using a correctly sized and optimised OG:Image makes your content more eye-catching in social media feeds. However, as each platform has different display standards, setting the correct OG:Image dimensions is essential.
In this article, we will examine why OG:Image sizes are important, the ideal dimensions for different platforms, and recommended best practices.
What Is OG:Image?
OG:Image is an HTML meta tag that forms part of the Open Graph (OG) protocol developed by Facebook. It determines which image will be displayed when content from a website is shared on social media. This tag allows a custom image to be assigned to shared links, making the content more eye-catching in social media feeds. When OG:Image is used with the correct dimensions and properly optimised, it can increase engagement rates and improve visibility for brands and content creators.
Why Are OG:Image Sizes Important?
OG:Image dimensions are highly important for the visual consistency, appeal, and engagement performance of content shared on social media platforms. Incorrectly sized or low-resolution images may be cropped, appear blurry, or be replaced by a default image selected by the platform. This can weaken brand perception and reduce the content’s click-through rate. Using the correct OG:Image dimensions ensures that your website is represented professionally, attractively, and effectively on social media.
Recommended OG:Image Sizes
OG:Image usage should be carefully optimised because each social media platform has different display standards. An incorrectly sized image may be cropped by the platform, appear blurry, or be displayed at the wrong aspect ratio. The recommended OG:Image dimensions for optimal display are as follows:
OG:Image Sizes for Facebook
As the platform that developed the Open Graph protocol, Facebook provides extensive support for OG:Image. You can use the following dimensions to ensure that link preview images shared on Facebook are displayed correctly:
- Recommended size: 1200 x 630 pixels
- Minimum size: 600 x 315 pixels
- Aspect ratio: 1.91:1
- File format: JPG or PNG
- File size: Must be smaller than 8 MB
For the best results on Facebook, it is recommended that you use a high-quality image measuring 1200 x 630 pixels. When a smaller image is used, Facebook may automatically scale it and reduce its quality.
OG:Image Sizes for Twitter
Twitter supports OG:Image tags but also has its own preview format, known as Twitter Cards. Twitter offers two different types of image cards:
1. Summary Card with Large Image (Large-Image Summary Card)
- Recommended size: 1200 x 675 pixels
- Aspect ratio: 16:9
- Minimum size: 300 x 157 pixels
- File format: JPG, PNG, or WebP
2. Summary Card (Small-Image Summary Card)
- Recommended size: 120 x 120 pixels (minimum)
- Aspect ratio: Square (1:1)
When sharing content on Twitter, using the Summary Card with Large Image format helps make your content more eye-catching.
OG:Image Sizes for LinkedIn and Pinterest
LinkedIn supports the Open Graph protocol, and it is important for images to present a professional appearance.
- Recommended size: 1200 x 627 pixels
- Aspect ratio: 1.91:1
- Minimum size: 552 x 276 pixels
- File format: JPG or PNG
Using high-quality and optimised images is important to ensure that links shared on LinkedIn are displayed effectively.
As Pinterest is a visually focused platform, longer vertical images are recommended.
- Recommended size: 1000 x 1500 pixels
- Aspect ratio: 2:3
- Minimum size: 600 x 900 pixels
Remember that vertical images tend to receive greater engagement when using OG:Image on Pinterest.
Using OG:Image for Instagram and WhatsApp
Instagram and WhatsApp do not fully support the Open Graph protocol. However, WhatsApp uses the OG:Image tag when generating link previews.
OG:Image for Instagram
As Instagram does not provide a link preview feature, OG:Image does not have a direct effect. However, you can use the correct image dimensions when using an Instagram Link Sticker or a link in your bio:
- Recommended size: 1080 x 1350 pixels (Feed post)
- Aspect ratio: 4:5
OG:Image for WhatsApp
OG:Image is used in previews of links shared on WhatsApp. However, the following dimensions should be considered to ensure that the platform retrieves and displays the image correctly:
- Recommended size: 1200 x 630 pixels
- Aspect ratio: 1.91:1
For the best results on WhatsApp, you can use the same OG:Image dimensions recommended for Facebook.
Using the correct OG:Image dimensions helps your content appear more professional, eye-catching, and effective across social media platforms. As each platform has different visual standards, the quality of your shared content may be directly affected. You can therefore optimise your link previews by using the recommended dimensions for platforms such as Facebook, Twitter, LinkedIn, Pinterest, WhatsApp, and Instagram. Correctly sized OG:Image visuals can strengthen your digital presence by helping your content receive more clicks, shares, and engagement.
