Use portrait where feed impact matters
4:5 gives a campaign more vertical space on mobile than square or landscape.
For 2027 planning, portrait 4:5 and square 1:1 remain practical feed formats. A 1080 × 1350 portrait asset gives mobile creative more vertical presence, while square remains flexible across placements.
There is no benefit in treating every Facebook placement as the same canvas. Keep a small set of master ratios and adapt deliberately.
| Format | Dimensions | Ratio | Design note |
|---|---|---|---|
| Portrait feed post | 1080 × 1350 px | 4:5 | Strong mobile feed presence. |
| Square feed post | 1080 × 1080 px | 1:1 | Flexible cross-placement working format. |
| Landscape / link image | 1200 × 630 px | ~1.91:1 | Useful for link previews and wide creative. |
| Story / Reel creative | 1080 × 1920 px | 9:16 | Full-screen vertical format; check interface overlays separately. |
4:5 gives a campaign more vertical space on mobile than square or landscape.
1:1 remains useful when a creative needs to travel across placements.
Do not assume a feed layout will survive a full-screen 9:16 placement without redesign.
Meta has continued to simplify video around Reels, while feed image creative still benefits from deliberate 4:5 or square composition. That makes a multi-ratio design system more useful than one “Facebook size.”
For 2027 work, keep the source artwork adaptable and judge each execution in the platform context it is actually intended for.
Preview profile details, copy, media and engagement around the artwork before you put the concept in front of stakeholders.

Often, but the surrounding interface and cropping behaviour can differ. Preview both placements before sign-off.
Use a full-screen 9:16 canvas such as 1080 × 1920 px and keep key content clear of interface overlays.
