Best Facebook Link Preview Image Size in 2026

For normal link previews, 1200 x 630 pixels is the cleanest Facebook image size to start with. It gives you the wide card shape most people expect and keeps the preview from feeling like a random thumbnail.

You can sometimes get away with other sizes, but that is not the point. The point is to use the size that breaks the least, looks intentional, and gives Facebook enough image data to render a good card.

Facebook can render previews differently across desktop, mobile, comments, Messenger, and shared posts. That means edge content is risky. Put the important stuff in the center and leave breathing room around it.

This is especially true for logos and headlines. If the logo is small and stuck in a corner, it can vanish on mobile. If the headline fills the whole canvas, it can feel cramped as soon as Facebook compresses it.

The best preview image is not just the right size. It also feels like the page it points to. If the user clicks and lands on something completely different, the card feels spammy even if the metadata is technically perfect.

Use the page title, product screenshot, article topic, or main offer as the visual anchor. Keep it honest and obvious.

Facebook can cache old previews, so do not assume a design change will show instantly everywhere. First test the URL and make sure the live Open Graph tags are correct. Then refresh the platform cache if needed.

If the tester sees the right `og:image`, your page is doing its job. After that, the remaining delay is usually Facebook cache behavior.
