Meta feed ads are 1080 × 1080 px (1:1), story and Reels ads are 1080 × 1920 px (9:16), and landscape ads are 1200 × 628 px (1.91:1).
Meta ads run across Facebook, Instagram, Messenger, and Audience Network. One creative rarely fits every placement — here are the 2026 specs for every Meta ad format.
| Asset | Dimensions | Ratio | Format | Max size |
|---|---|---|---|---|
| Feed Ad — Square | 1080 × 1080 | 1:1 | JPG / PNG | 30 MB |
| Story / Reels Ad | 1080 × 1920 | 9:16 | JPG / MP4 | 30 MB |
| Landscape Ad | 1200 × 628 | 1.91:1 | JPG / PNG | 30 MB |
| Carousel Ad | 1080 × 1080 | 1:1 | JPG / PNG | 30 MB per card |
| Marketplace Ad | 1200 × 1200 | 1:1 | JPG / PNG | 30 MB |
| Right Column Ad (desktop) | 1200 × 1200 | 1:1 | JPG / PNG | 30 MB |
Pro tip: Meta recommends 1:1 square as the safest single-creative size — it works across Feed, Marketplace, and Right Column with minimal cropping. For Stories and Reels always use 9:16.

Why Meta Ads Image Size Matters
Meta's ad quality score directly affects your CPC. Poorly sized creative that gets auto-cropped triggers low-quality signals — even if the underlying image is great. Uploading at the correct dimensions for each placement keeps the ad quality score high and CPCs low.
Placement Strategy
- 1:1 (1080 × 1080) — safest single-creative size for Feed, Marketplace, and Right Column.
- 9:16 (1080 × 1920) — required for Story and Reels placements.
- 1.91:1 (1200 × 628) — best for link ads that open external URLs.
Common mistakes to avoid
- Using one 1.91:1 landscape image across Story placements — Meta letterboxes it with blurred bars.
- Putting more than 20% text over the image — historically hurt reach and still lowers quality score.
- Uploading below 1080 px on the short edge — Meta upscales and blurs the ad.
Frequently asked questions
What is the best image size for Meta ads in 2026?
1080 × 1080 px (1:1 square) is the safest single-creative size across Feed, Marketplace, and Right Column placements. For Stories and Reels use 1080 × 1920 px.
What size should a Meta story ad be?
Meta Story and Reels ads are 1080 × 1920 px (9:16 vertical).
Does Meta charge more for the wrong ad size?
No, but incorrect sizes reduce ad quality score, which increases cost-per-click. Right-sized creative reliably lowers CPC.
What is the maximum Meta ad image file size?
30 MB per image across all placements.
Should I upload multiple sizes for one Meta campaign?
Yes. Meta's Advantage+ Creative Optimization uses the best size per placement, so upload 1:1, 9:16, and 1.91:1 versions of each creative.
JPG or PNG for Meta ads?
Use JPG for photos and PNG for graphics with text or transparency. Meta compresses both — start from the highest-quality source.
