Frequently Asked Questions
Why 1200×630 specifically?
That’s Facebook’s recommended size for link and post preview images, giving the clearest, least-cropped display across feed and mobile.
Will my image be cropped or just shrunk to fit?
Cropped to exactly fill the 1200×630 frame, centered — not letterboxed with empty space.
Does this work for both photo posts and shared link previews?
Yes — 1200×630 is the standard size used for both contexts on Facebook.
Will a square photo lose a lot of content when resized?
Some — fitting a square photo into the wider 1200×630 frame crops off the top and bottom evenly to fill the width.
