Why 1200×630 is still the Facebook post answer

The Facebook post canvas has two canonical sizes, and which one wins depends on what you are posting. 1200×630 at a 1.91:1 ratio is the historical answer because it maps to the OpenGraph link-card standard — any time someone shares a URL on Facebook, the platform pulls the og:image from that page and renders a preview at exactly those dimensions. If the image is off-ratio, Facebook center-crops it horizontally and hides the edges. For a pure photo post with no URL attached, 1080×1080 square now earns more feed real estate than 1.91:1 and performs better on mobile, which is where the overwhelming majority of Facebook consumption happens. The performance-optimal choice in 2026 is actually portrait 4:5 at 1080×1350, which pulls roughly ten percent more vertical pixels than square and matches Instagram's bias — useful if you cross-post between the two Meta surfaces.

The ingest pipeline matters almost as much as the composition. Facebook heavily re-encodes every upload, converts non-sRGB color profiles silently, and serves the displayed image at roughly 500 pixels wide on mobile feed. Uploading at 2400×1260 does not gain you quality on feed — the platform downsamples anything larger than ~1200 px wide for the display version and keeps the original only for the tap-to-expand view. The workflow that holds up: stay at 1200×630 for link cards and 1080×1080 for photo posts, export as sRGB JPEG to avoid color shift, and keep shadow-heavy product cutouts clean because Facebook's compressor amplifies grey halos around soft edges. This preset handles all three — the canvas lock, the sRGB output, and the shadow-reduction pass tuned for product shots.

What makes Facebook post images different from Instagram

Facebook and Instagram share ingestion infrastructure but not consumption patterns. Facebook's feed is about half business pages, half personal updates, and the link-card format dominates because pages post URLs constantly — something Instagram does not really support. That means the 1200×630 canvas sees more use on Facebook than anywhere else, and optimizing for it matters. The second difference is dominance of mobile: Facebook's desktop share is higher than Instagram's, so your image needs to read at both a 500 px wide mobile render and a roughly 750 px wide desktop column. A clean subject cutout on a restrained backdrop survives both. This tool exports both landscape and square in one session so you can test which converts better for your specific audience without re-uploading.
