Facebook Aspect Ratio: Feed Images & Reels Sizes
Compare Facebook feed image and Reels canvases. Calculate square, portrait and widescreen sizes and adapt a feed post without stretching.
A feed graphic and an immersive Reel are not interchangeable exports. These examples help plan their geometry, not certify every Facebook upload requirement. The calculator starts with a square 1080 × 1080 canvas.

| Layout | Ratio | Calculate size (px) | Use and limitations |
|---|---|---|---|
| Square feed graphic | 1:1 | 1080 × 1080 | 1:1 design example, not a required feed size. |
| Portrait feed graphic | 4:5 | 1080 × 1350 | 4:5 design example; check the publishing preview. |
| Reel portrait layout | 9:16 | 1080 × 1920 | 9:16 full-screen working canvas. |
| Landscape video layout | 16:9 | 1920 × 1080 | 16:9 comparison; appearance depends on the destination. |
Facebook feed images versus Reels
A square canvas can hold a compact feed graphic, while a 4:5 portrait leaves more vertical room for a photograph or headline. A Reel designed for a tall viewer uses a different composition. Meta’s official Reels advertising guidance emphasizes 9:16 creative with key messages clear of overlays. That does not mean every Facebook video or organic feed image must have a 9:16 ratio.
Adapt a square announcement to portrait
To keep a 1080 × 1080 design intact inside 1080 × 1350, add 270 rows of canvas space. Centering adds 135 above and below. Cropping the square to 4:5 instead keeps 864 × 1080 and removes 108 pixels from each side, retaining 80% of its area. If the outer edges contain a logo or date, padding or rebuilding the layout can preserve information that the crop would remove.
Build a Reel from a feed image
A 1080 × 1350 feed graphic placed inside 1080 × 1920 has 570 extra rows to fill. Use that space intentionally rather than pulling the image taller and distorting lettering. A sequence of reframed details, an explanation above the image, or a fresh portrait composition may communicate better than a static padded graphic. Aspect-ratio math identifies the mismatch but cannot choose the story for you.
Preview each placement independently
When publishing to several Facebook surfaces, inspect each preview rather than assuming the same crop will be used everywhere. Paid campaigns may need placement-specific assets; organic publishing can also present a cover or preview differently from the opened media. Keep essential text inside the planned frame and check it on a phone before release. The calculator is not a simulation of Facebook’s feed or ad delivery.
Separate aspect ratio from upload quality
A 720 × 720 image and a 1080 × 1080 image are both square. The larger file has more pixels but may not look better if the source was enlarged or heavily compressed. Export from the best available original, use the intended width and height, and check the actual result after processing. File format, duration and compression limits should be verified for the particular destination independently.
Plan a different shape without stretching
Compare cropping and padding in the main calculator before editing. The tools plan dimensions only; they do not upload or edit your image or video.
