Meta ad specs and sizes
Meta's Ads Guide recommends 4:5 at 1440 x 1800 pixels for Facebook and Instagram feed images and video, and 9:16 at 1440 x 2560 for Stories and Reels, with 1:1 at 1080 x 1080 or larger for carousel cards. Images can be up to 30MB as JPG or PNG, and videos up to 4GB.
Recommended sizes by placement
These are the recommended specs from Meta's own Ads Guide, checked placement by placement.
| Placement | Ratio | Pixels | File types | Max file size |
|---|---|---|---|---|
| Facebook Feed image[1] | 4:5 | 1440 x 1800 | JPG, PNG | 30MB |
| Instagram Feed image[2] | 4:5 | 1440 x 1800 | JPG, PNG | 30MB |
| Instagram Stories image[3] | 9:16 | 1440 x 2560 | JPG, PNG | 30MB |
| Facebook Feed video[4] | 4:5 | 1440 x 1800 | MP4, MOV, GIF | 4GB |
| Instagram Reels video[5] | 9:16 | 1440 x 2560 | MP4, MOV | 4GB |
| Facebook Feed carousel card[6] | 1:1 | 1080 x 1080 or larger | Image or video | 30MB image, 4GB video |
Feed: design for 4:5
For both Facebook and Instagram Feed, Meta recommends a 4:5 image at 1440 x 1800 pixels. On Facebook the minimum is 600 pixels wide and 750 high, with a 3% tolerance on the ratio.[1] Instagram Feed accepts ratios from 4:5 up to 1.91:1 with a 1% tolerance and a 500-pixel minimum width.[2]
Feed video follows the same 4:5 at 1440 x 1800. Meta asks for H.264 compression, a fixed frame rate, progressive scan and stereo AAC audio at 128kbps or more, and lists captions as optional but recommended.[4] On mobile Feed, if you use the Awareness objective or a reach or impressions goal, the headline, description and button won't show.[4]
Stories and Reels: design for 9:16 and the safe zone
Stories and Reels are full-screen vertical, 9:16 at 1440 x 2560. Instagram Stories images need at least 500 pixels of width.[3] Reels video can run from 0 seconds to 15 minutes; minimum width is 250 pixels under 30 seconds and 500 pixels at 30 seconds or longer, and Meta calls sound optional but strongly recommended.[5]
The interface sits on top of vertical ads. Meta suggests leaving about 14% at the top, 35% at the bottom and 6% on each side clear of text, logos and the product.[5][3] On a 1440 x 2560 frame that means keeping key elements out of the top 358 pixels, the bottom 896 pixels and 86 pixels at each edge.
Carousel: 2 to 10 square cards
A Facebook Feed carousel holds 2 to 10 cards. Meta recommends 1:1 at 1080 x 1080 or larger with a 3% tolerance, image cards up to 30MB and video cards up to 4GB, and each card needs a landing page URL.[6] Carousels suit a product range, a step-by-step story, or one product shown from several sides.
Text lengths
| Placement | Primary text | Headline |
|---|---|---|
| Facebook Feed image or video[1] | 50 to 150 characters | 27 characters |
| Instagram Feed image[2] | 125 characters | 40 characters |
| Instagram Stories image[3] | 125 characters | n/a |
| Instagram Reels video[5] | 44 characters | n/a |
| Facebook Feed carousel[6] | 80 characters | 20 characters (18 for description) |
A practical export list
For one concept, export three files and you cover almost every placement:
- 4:5, 1440 x 1800 for Facebook and Instagram Feed.
- 9:16, 1440 x 2560 with the safe zone respected, for Stories and Reels.
- 1:1, 1080 x 1080 if the concept also runs as a carousel card.
Then let Meta pick which version shows where. Write the first line of primary text so it works alone, because that's often all people see before "more".

Common questions
What size should a Facebook ad image be?
Meta recommends 4:5 at 1440 x 1800 pixels for Facebook Feed, JPG or PNG, up to 30MB, at least 600 pixels wide. For Stories and Reels use 9:16 at 1440 x 2560.
Is 1:1 still a good size for Meta ads?
Square still works and is Meta's recommendation for carousel cards (at least 1080 x 1080). For single image and video ads in feeds, Meta now recommends 4:5, which takes up more of the screen on a phone.
What is the safe zone for Reels and Stories ads?
Meta suggests keeping about 14% at the top, 35% at the bottom and 6% on each side free of text, logos and key visuals, so the profile icon, caption and call-to-action button don't cover them.
How long can a Facebook video ad be?
Meta's Facebook Feed specs allow 1 second to 241 minutes, and Instagram Reels ads up to 15 minutes. Most ads that work are far shorter; the limit is not a target.
How much primary text should a Meta ad have?
Meta recommends 50 to 150 characters of primary text and a 27-character headline for Facebook Feed, and 125 characters of primary text for Instagram Feed and Stories. Longer text is truncated behind a 'more' link.
