What size is a Facebook ad?

Meta recommends 4:5 vertical at 1440 x 1800 pixels for Facebook Feed images and video, and 9:16 at 1440 x 2560 pixels for Stories and Reels. Facebook carousel cards are 1:1, at least 1080 x 1080 pixels.

What is the Instagram Story ad size?

9:16 vertical at 1440 x 2560 pixels. Keep about 14% at the top, 35% at the bottom and 6% on each side free of text and logos.

What is the best aspect ratio for Meta ads?

4:5 for Feed and 9:16 for Stories and Reels. Uploading both versions of the same ad covers almost every placement.

What is the maximum file size for Facebook ads?

30 MB for images and 4 GB for videos, according to Meta's Ads Guide.

How long can primary text be?

Meta recommends 50-150 characters for Facebook Feed and 125 for Instagram Feed and Stories. Longer text is allowed but cut off with "See more", so put the most important words first.

Can I use the same image for Feed and Stories?

You can, but a single file gets cropped or shown with empty space in one of them. Uploading a 4:5 version for Feed and a 9:16 version for Stories and Reels looks better in both.

The short answer

For most Meta ads you need just three shapes: 4:5 for Facebook and Instagram Feed, 9:16 for Stories and Reels, and 1:1 for Facebook carousel cards. Meta recommends 1440 x 1800 pixels for 4:5 and 1440 x 2560 pixels for 9:16.

Facebook and Instagram ad sizes: quick reference

Placement	Aspect ratio	Recommended size	Max file size	Text (recommended)
Facebook Feed image	4:5	1440 x 1800 px (min 600 x 750)	30 MB	Primary 50-150 characters, headline 27
Facebook Feed video	4:5	1440 x 1800 px	4 GB, 1 second to 241 minutes	Primary 50-150 characters, headline 27
Instagram Feed image	4:5 (accepted from 4:5 to 1.91:1)	1440 x 1800 px (min width 500)	30 MB	Primary 125, headline 40
Instagram Feed video	9:16 (as listed by Meta)	1080 x 1920 px	4 GB, 1 second to 60 minutes	Primary 125
Facebook Stories image	9:16	1440 x 2560 px (min width 500)	30 MB	Primary 125, headline 40
Instagram Stories image	9:16	1440 x 2560 px (min width 500)	30 MB	Primary 125
Instagram Stories video	9:16	1440 x 2560 px	4 GB, 1 second to 60 minutes	Primary 125
Instagram Reels video	9:16	1440 x 2560 px	4 GB, up to 15 minutes	Primary 44
Facebook Feed carousel	1:1, 2 to 10 cards	At least 1080 x 1080 px	30 MB image, 4 GB video (1 second to 240 minutes)	Primary 80, headline 20, description 18
Instagram Feed carousel	4:5 for image cards, 1:1 for video cards	At least 1080 x 1080 px	30 MB image, 4 GB video (1 second to 2 minutes)	Primary 125

Images: JPG or PNG. Video: MP4 or MOV (GIF is also accepted in Feed and Stories). Text lengths are Meta's recommendations, not hard limits: longer text is cut off with "See more".

Feed ads: 4:5

Meta recommends 4:5 vertical for Feed on both Facebook and Instagram, at 1440 x 1800 pixels. A 4:5 ad takes up more of the phone screen than a square or landscape one, which gives it more room to stop the scroll.

Instagram Feed accepts anything from 4:5 to 1.91:1 landscape. Landscape still works, but it shows much smaller on a phone. Facebook carousel cards are square, 1:1, at least 1080 x 1080 pixels, with 2 to 10 cards per ad.

Stories and Reels: 9:16 and the safe zone

Stories and Reels are full-screen and vertical: 9:16, at 1440 x 2560 pixels. Facebook Reels is a full-screen vertical placement too; Meta's Ads Guide lists its exact limits.

The profile name sits at the top and the caption and call-to-action button at the bottom, covering part of your creative. Meta's guidance is to keep roughly 14% at the top, 35% at the bottom and 6% on each side free of text, logos and other key elements.

On a 1440 x 2560 px canvas:

Top 14% = keep the first 358 px clear

Bottom 35% = keep the last 896 px clear

Sides 6% = keep 86 px clear on the left and right

One ad, every placement

You do not have to choose one shape. With Advantage+ placements, Meta shows your ad wherever it is likely to perform, and you can upload a different file for each placement group: a 4:5 version for Feed and a 9:16 version for Stories and Reels.

The practical setup for most advertisers is two files per ad: 4:5 and 9:16. Design the 9:16 version with the safe zone in mind, and keep the hook and product visible in the middle of the frame so both versions work.

Video specs worth knowing

Format: MP4 or MOV with H.264 compression, square pixels, a fixed frame rate and progressive scan (Meta's Reels specs).
Audio: stereo AAC at 128 kbps or more.
Captions and sound are optional, but Meta recommends both for Reels. Feed video is often watched with the sound off, so burn in captions or use on-screen text.
Length limits vary by placement: Instagram Stories and Feed video up to 60 minutes, Reels up to 15 minutes, Instagram carousel video cards up to 2 minutes. Most ads work best far shorter than the limit.

Common mistakes

Text or the offer placed in the bottom third of a Story or Reel, where the call-to-action button covers it.
Using a landscape 1.91:1 image in Feed, where it shows small next to 4:5 ads.
Uploading one square file and letting Meta crop it for Stories, which can cut off text and faces.
Low-resolution files. Meta's minimums are small (600 px wide for Facebook Feed images), but the recommended 1440 px width is what looks sharp on modern phones.
Long primary text without a strong first line. Only the start shows before "See more".

Once your ads are live, check how each placement performs with the CTR calculator and CPM calculator. For winning ideas to build in these sizes, see how to research competitors in the Meta Ads Library guide.
