OG Image Checker

OG Image Size Requirements by Platform

Use these specs to ensure your Open Graph images display correctly everywhere.

OG Image Best Practices

• Use 1200 × 630 px as your default — This single size satisfies Facebook, Twitter large cards, LinkedIn, and Slack. It renders at exactly 2× on retina displays at the standard 600 × 315 display size.
• Keep the file under 300 KB — Large images slow down social crawlers and mobile users. Compress with tools like Squoosh or TinyPNG. Use JPEG for photos, PNG for text-heavy graphics.
• Include your brand in the image — OG images act as mini ads in social feeds. Adding your logo, brand colors, or a consistent visual style increases recognition and click-through rates.
• Use an absolute URL for og:image — Always specify a full URL (https://example.com/og.jpg), never a relative path. Social crawlers don't resolve relative URLs — your image simply won't appear.
• Add og:image:width and og:image:height tags — These hints let platforms render the correct placeholder before fetching your image, improving page load appearance and preventing layout shifts.

Frequently Asked Questions

What is the ideal OG image size?

The universally recommended OG image size is 1200 × 630 pixels at a 1.91:1 aspect ratio. This works across Facebook, Twitter/X (large card), LinkedIn, and Slack. Using this one size ensures your image looks sharp on every platform without needing separate images.

Why does my OG image look blurry or cropped on social media?

Blurry images usually mean your image is too small — below 600 × 315 px. Social platforms upscale small images, causing pixelation. Cropping happens when your image's aspect ratio doesn't match the 1.91:1 expectation, causing platforms to auto-crop to fit. Use this checker to verify dimensions before publishing.

Does file size matter for OG images?

Yes. Facebook recommends keeping OG images under 8 MB. In practice, optimized images under 300 KB load faster, especially on mobile connections. Use PNG for images with text/graphics and JPEG for photos. WebP is also supported by most modern platforms.

Can I use the same image for all social platforms?

Yes — a 1200 × 630 px image at 1.91:1 works on all major platforms. The only exception is Twitter summary cards, which use a 1:1 square crop. If you use twitter:card = summary_large_image, your 1.91:1 image works perfectly.

What's the difference between og:image and twitter:image?

og:image is the Open Graph standard used by Facebook, LinkedIn, and Slack. twitter:image is Twitter/X's own tag. When twitter:image is absent, Twitter falls back to og:image — so in most cases you only need og:image. Set twitter:image explicitly only if you want a different image on Twitter than on other platforms.

Why isn't my OG image updating on Facebook or LinkedIn?

Social platforms cache OG images aggressively. After updating your og:image URL, use Facebook's Sharing Debugger (developers.facebook.com/tools/debug) or LinkedIn's Post Inspector (linkedin.com/post-inspector) to force a cache refresh. Alternatively, change the image URL (add a query string like ?v=2) to force platforms to fetch the new image.
