Facebook Ad Sizes & Specs (2026)
Facebook ads are bought through Meta Ads Manager, and Meta recommends uploading the highest-resolution source it will accept rather than pre-cropping to each placement. A single square or vertical image is up-scaled and cropped across dozens of placements, so the safest workflow is to design a 1080 × 1080 (feed) and a 1080 × 1920 (Stories/Reels) master and let Advantage+ placements handle the rest. Facebook renders very few characters of primary text before a “See more” truncation on mobile, so front-load your hook.
Facebook ad specifications
| Placement | Dimensions (px) | Aspect ratio | Max file size | File types | Headline | Body text | Notes |
|---|---|---|---|---|---|---|---|
| Feed image (square) | 1080 × 1080 | 1:1 | 30 MB | JPG, PNG | 40 chars | 125 chars | Minimum width 600 px. Most reliable single feed size. |
| Feed image (vertical) | 1080 × 1350 | 4:5 | 30 MB | JPG, PNG | 40 chars | 125 chars | Tallest allowed feed ratio; takes more vertical space on mobile. |
| Stories & Reels | 1080 × 1920 | 9:16 | 30 MB | JPG, PNG | — | 125 chars | Keep text/logo in the middle 1080 × 1420; top and bottom are covered by UI. |
| Right column | 1080 × 1080 | 1:1 | 30 MB | JPG, PNG | 40 chars | — | Desktop-only; displayed small, so avoid fine detail. |
| Marketplace | 1080 × 1080 | 1:1 | 30 MB | JPG, PNG | 40 chars | 125 chars | Uses the same square asset as feed. |
| Carousel card | 1080 × 1080 | 1:1 | 30 MB | JPG, PNG | 40 chars | 125 chars | 2–10 cards; each card is square and can carry its own headline and link. |

Tips for Facebook ad creative
- Keep the most important text and your logo inside the center of vertical creatives — Stories and Reels overlay UI (profile, caption, CTA) across the top ~14% and bottom ~20%.
- Meta no longer hard-rejects ads over 20% text, but text-heavy images still get suppressed reach — keep copy minimal on the image itself.
- Primary text truncates around 125 characters on mobile feed; put the offer in the first sentence.
- Use 1:1 or 4:5 for feed to maximize vertical screen real estate; 4:5 (1080 × 1350) is the tallest feed image Facebook allows.
Facebook ad size FAQ
What size is a Facebook ad?+
The most versatile Facebook ad size is 1080 × 1080 pixels (1:1) for feed placements and 1080 × 1920 pixels (9:16) for Stories and Reels. Meta recommends uploading at least 1080 px on the shortest side; it will resize and crop your image for other placements automatically.
What is the best Facebook ad size in 2026?+
For feed, 1080 × 1350 pixels (4:5) is often the best performer because it occupies the most vertical space on mobile without being cropped. For full-screen placements, use 1080 × 1920 pixels (9:16). Provide both a 4:5 and a 9:16 asset to cover every placement.
What is the maximum file size for a Facebook image ad?+
Facebook image ads can be up to 30 MB. Use JPG or PNG, keep the image at least 600 pixels wide, and aim for the highest resolution available so the ad stays sharp across devices.
How many characters can a Facebook ad have?+
Facebook shows about 125 characters of primary text before truncating with a “See more” link on mobile, and headlines display best under 40 characters. Front-load your key message so it appears before the cut-off.
Do Facebook ads still have a 20% text rule?+
Meta retired the hard 20% text overlay rejection, so ads are no longer blocked for too much text. However, image-heavy text can still reduce delivery and raise costs, so keeping on-image copy minimal remains best practice.
