AI Facebook Ad Generator
Create scroll-stopping Facebook ads — feed, story, reel and carousel formats — across 20+ models, ready for every placement in minutes.
What are the best Facebook ad sizes?
For the Facebook feed, Meta recommends a 4:5 image (1080 × 1350 px, up to 1440 × 1800 px) because it takes the most vertical space on mobile; a 1:1 square (1080 × 1080 px) also works well. Stories and Reels use a full-screen 9:16 (1080 × 1920 px), and carousel cards are 1:1 (1080 × 1080 px). VapuAI generates each of these placements from one brief across 20+ models, so you can fill Advantage+ placements with format-correct creative — feed, story, reel and carousel — in minutes instead of re-shooting per size.
Facebook ad specifications
Recommended dimensions per Meta's Ads Guide. Feed images should keep primary text short (roughly 125 characters) so it is not truncated.
| Format | Dimensions | Notes |
|---|---|---|
| Feed (4:5) | 1080 × 1350 px | Recommended; up to 1440 × 1800 px, 4:5 ratio |
| Feed (1:1) | 1080 × 1080 px | Square alternative for the feed |
| Stories (9:16) | 1080 × 1920 px | Full-screen; keep key content clear of top/bottom 14% |
| Reels (9:16) | 1080 × 1920 px | Full-screen vertical |
| Carousel card (1:1) | 1080 × 1080 px | 2–10 cards per carousel |

Questions, answered
What image size should a Facebook feed ad be?
Meta recommends a 4:5 image at 1080 × 1350 px (up to 1440 × 1800 px) for the feed because it uses the most vertical space on mobile. A 1:1 square at 1080 × 1080 px is also supported. VapuAI can generate either ratio directly.
Can I make Facebook Stories and Reels ads?
Yes. Stories and Reels are full-screen 9:16 at 1080 × 1920 px. Generate the vertical creative from the same brief you use for the feed, so every placement stays consistent.
Does it support carousel ads?
Yes — carousel cards are 1:1 at 1080 × 1080 px, and a carousel can hold 2–10 cards. Generate a set of matching square frames so the carousel reads as one story.
Will the creative work with Advantage+ placements?
Because you can export feed, story, reel and carousel sizes from one brief, you can supply native, format-correct creative for each Advantage+ placement rather than letting one ratio get cropped everywhere.
