Facebook Ad Sizes & Specs Cheat Sheet (2026): Every Placement
If you run Facebook ads, you have hit this wall: you finish a creative, upload it, and Meta crops your logo in half or flags the image as low resolution. The fix is knowing the exact spec for the placement before you design, not after.
This is the complete reference. Below you will find one master table covering every Facebook and Meta placement, then a detailed breakdown for each: recommended pixel dimensions, aspect ratio, minimum resolution, maximum file size, supported formats, and the primary text, headline, and description character limits. Safe-zone guidance is included for vertical placements like Stories and Reels where the interface overlaps your creative.
All numbers reflect Meta's current ad guide recommendations. Where Meta publishes a range rather than a single value, we give the range instead of a made-up precise number. Specs change, so when you are shipping a high-budget campaign, confirm against Meta's in-platform Ad Format Specs page before launch.
Pro tip: design at the largest recommended size, then export down. A 1080x1350 master can be cropped to 1:1 or letterboxed to 16:9, but you cannot upscale a small file without it looking soft. One vertical master plus a square export covers ~90% of Advantage+ placements.
Master Spec Table (All Placements)
| Placement | Recommended size (px) | Aspect ratio | Max file size | Formats |
|---|---|---|---|---|
| Feed image | 1080 x 1080 or 1080 x 1350 | 1:1 or 4:5 | 30 MB | JPG, PNG |
| Feed video | 1080 x 1080 or 1080 x 1350 | 1:1 or 4:5 | 4 GB | MP4, MOV, GIF |
| Stories (image/video) | 1080 x 1920 | 9:16 | 30 MB image / 4 GB video | JPG, PNG, MP4, MOV |
| Reels | 1080 x 1920 | 9:16 | 4 GB | MP4, MOV |
| Carousel (per card) | 1080 x 1080 | 1:1 | 30 MB image / 4 GB video | JPG, PNG, MP4, MOV |
| Right column | 1080 x 1080 (displays ~254 x 133) | 1:1 (renders ~1.91:1) | 30 MB | JPG, PNG |
| Marketplace | 1080 x 1080 | 1:1 | 30 MB image / 4 GB video | JPG, PNG, MP4, MOV |

| Messenger inbox | 1080 x 1080 | 1:1 | 30 MB | JPG, PNG |
| Messenger Stories | 1080 x 1920 | 9:16 | 30 MB image / 4 GB video | JPG, PNG, MP4, MOV |
| Audience Network native/banner | 1080 x 1080 | 1:1 (banner 16:9) | 30 MB image / 4 GB video | JPG, PNG, MP4, MOV |
| Audience Network rewarded video | 1080 x 1920 | 9:16 | 4 GB | MP4, MOV |
Universal minimums per Meta's current ad guide: images should be at least 1080 px on the longest side, JPG or PNG, and avoid text that covers most of the image. Video should be H.264 compression, square pixels, fixed frame rate, with AAC audio at 128 kbps or higher.
Text & Character Limits (Apply To Most Placements)
| Element | Recommended limit | Notes |
|---|---|---|
| Primary text | ~125 characters | Text beyond this gets truncated with a "See more" on most placements |
| Headline | ~27-40 characters | Mobile feed often shows only the first ~27 |
| Link description | ~27-30 characters | Frequently hidden entirely on mobile; do not rely on it |
Meta technically allows far longer copy, but the recommended limits above are where your message stays fully visible without a click-to-expand. Front-load the hook. Need help writing copy that fits these limits? Try the free Facebook ad copy generator.
Feed (Image and Video)
The News Feed is where most budget goes, and 4:5 is the workhorse ratio because it takes up more vertical screen space on mobile than 1:1 without getting cropped.
| Spec | Image | Video |
|---|---|---|
| Recommended size | 1080 x 1080 or 1080 x 1350 | 1080 x 1080 or 1080 x 1350 |
| Aspect ratio | 1:1 or 4:5 | 1:1, 4:5 (up to 9:16 supported) |
| Min resolution | 1080 x 1080 | 1080 x 1080 |
| Max file size | 30 MB | 4 GB |
| Length | n/a | 1 second to 241 minutes (15-30s converts best) |
| Formats | JPG, PNG | MP4, MOV, GIF |
For feed video, add captions. The majority of feed video is watched on mute, so on-screen text or burned-in subtitles do most of the persuading.
Stories (Image and Video)
Stories are full-screen vertical. The danger here is the safe zone: the top and bottom of the frame are covered by the interface.
- Recommended size: 1080 x 1920, aspect ratio 9:16
- Max file size: 30 MB image, 4 GB video
- Video length: up to 60 seconds per card
- Formats: JPG, PNG, MP4, MOV
Safe zone: keep your logo, headline, and call to action inside the middle ~80% of the frame. Leave roughly the top 14% clear of critical content (profile name and icons) and the bottom 20% clear (the CTA button and "Sponsored" label). Anything important in those edges risks being obscured or tapped accidentally.
Reels
Reels use the same 9:16 vertical canvas as Stories but the interface elements sit differently, so the safe zone is tighter at the bottom where the caption, audio attribution, and action buttons stack.
- Recommended size: 1080 x 1920, aspect ratio 9:16
- Max file size: 4 GB
- Length: Meta favors short Reels; 15 seconds or less tends to hold completion rate
- Formats: MP4, MOV
Safe zone: keep text and key visuals out of the bottom ~35% and the right edge, where the like, comment, share, and audio UI overlap. A common mistake is centering a subtitle vertically and watching the engagement buttons cover it.
Carousel
Carousels show two or more cards the viewer swipes through. Each card is its own creative with its own headline and link.
| Spec | Detail |
|---|---|
| Cards | 2 to 10 |
| Recommended size | 1080 x 1080 per card |
| Aspect ratio | 1:1 (use the same ratio for every card) |
| Max file size | 30 MB image / 4 GB video per card |
| Formats | JPG, PNG, MP4, MOV |
Keep every card the same aspect ratio. Mixing a 1:1 card with a 4:5 card breaks the seamless swipe and Meta may reject or letterbox the set. Carousels are strong for product ranges, step-by-step explainers, and before/after sequences.
Right Column
The desktop right-hand rail. Small, cheap, and image-only, so simplicity wins.
- Upload size: 1080 x 1080, but it renders small at roughly 1.91:1
- Max file size: 30 MB
- Formats: JPG, PNG
Because the rendered placement is tiny, avoid fine print. A bold logo, one product, and a high-contrast background read far better than a busy composition.
Marketplace
Ads in Facebook Marketplace appear between listings and follow standard square feed specs.
- Recommended size: 1080 x 1080, aspect ratio 1:1
- Max file size: 30 MB image / 4 GB video
- Formats: JPG, PNG, MP4, MOV
Marketplace shoppers are in a buying mindset, so creative that looks like a clean product listing (single item, plain background, clear price-anchoring) tends to outperform lifestyle imagery here.
Search Results
Ads can surface within Facebook and Marketplace search results. Use the standard square asset; there is no separate creative to build.
- Recommended size: 1080 x 1080, aspect ratio 1:1
- Max file size: 30 MB image / 4 GB video
- Formats: JPG, PNG, MP4, MOV
In-Stream Video
In-stream ads play before or during longer video content, so they behave more like a short commercial than a scroll-stopper.
- Recommended size: 1080 x 1080 (16:9 landscape also supported)
- Aspect ratio: 1:1 or 16:9
- Max file size: 4 GB
- Length: roughly 5 to 120 seconds; mid-roll favors 10 seconds or under
- Formats: MP4, MOV
Hook within the first few seconds and assume sound is on, unlike feed. A clear brand moment early protects you if the viewer skips.
Messenger
Messenger has two surfaces: the inbox (where ads appear between conversations) and Messenger Stories.
| Surface | Recommended size | Aspect ratio | Max file size |
|---|---|---|---|
| Inbox | 1080 x 1080 | 1:1 | 30 MB |
| Stories | 1080 x 1920 | 9:16 | 30 MB image / 4 GB video |
Inbox ads render small, like the right column, so keep them clean. Messenger Stories follow the same safe-zone rules as Facebook Stories.
Audience Network
Audience Network extends your ads to third-party apps and sites outside Facebook. Formats vary by host app, but these are the standard targets.
| Format | Recommended size | Aspect ratio | Max file size |
|---|---|---|---|
| Native / interstitial | 1080 x 1080 | 1:1 | 30 MB image / 4 GB video |
| Banner | varies by app | 16:9 | 30 MB |
| Rewarded video | 1080 x 1920 | 9:16 | 4 GB |
Because you do not control the host app's layout, supply your highest-resolution square and vertical assets and let Meta adapt them. Avoid edge-to-edge text that a host frame might clip.
Which Size For Which Goal
You do not need ten different files. Match the ratio to the objective.
| Goal | Best ratio | Why |
|---|---|---|
| Maximize mobile feed real estate | 4:5 (1080 x 1350) | Fills more vertical screen than 1:1 without cropping |
| Run everywhere with one asset | 1:1 (1080 x 1080) | The most universally accepted ratio across placements |
| Stories, Reels, full-screen immersion | 9:16 (1080 x 1920) | Native vertical; required for Reels |
| Show a product range or sequence | Carousel 1:1 | Multiple cards, multiple links, one swipe |
| Cheap retargeting / reminder | 1:1 for right column + inbox | Low CPM placements, simple creative |
Once your sizes are dialed in, the rest of the campaign (budget, targeting, structure) determines whether they actually convert.

Frequently Asked Questions
What is the best size for a Facebook ad?
For most campaigns, 1080 x 1350 pixels (the 4:5 vertical ratio) is the best all-around image size because it occupies the most vertical space on mobile feeds without being cropped. For maximum cross-placement compatibility, 1080 x 1080 (1:1 square) is the safest single asset. Build vertical first, then export a square version.
What size are Facebook ads in 2026?
The current recommended sizes are 1080 x 1080 (1:1) or 1080 x 1350 (4:5) for feed images and video, and 1080 x 1920 (9:16) for Stories and Reels. Images should be at least 1080 pixels on the longest side. These reflect Meta's current ad guide; always design at 1080 px or larger.
Is 1:1 or 4:5 better for Meta ads?
4:5 (1080 x 1350) is generally better for the mobile News Feed because it takes up more screen height, which usually means more attention and better cost per result. 1:1 (1080 x 1080) is more versatile across every placement including right column, Marketplace, and inbox. Many advertisers run 4:5 for feed-heavy campaigns and keep a 1:1 backup for placements that prefer square.
What is the 20% text rule on Facebook ads?
The old rule rejected or limited reach for image ads where text covered more than 20% of the image. Meta retired the hard 20% restriction, so ads are no longer blocked for it. However, images with heavy text overlay still tend to perform worse and Meta still recommends keeping text minimal, so the spirit of the rule remains good practice.
Is 1080x1350 4:5 or 3:4?
1080 x 1350 is a 4:5 aspect ratio. Dividing 1080 by 1350 gives 0.8, which equals 4 divided by 5. A 3:4 ratio at 1080 wide would be 1080 x 1440, which is taller. For Facebook feed ads, use 4:5 (1080 x 1350), not 3:4.
What file formats and sizes does Facebook accept?
Images should be JPG or PNG up to 30 MB. Video should be MP4 or MOV (H.264, AAC audio) up to 4 GB. Use square pixels, a fixed frame rate, and at least 1080 px resolution. GIFs are accepted in feed placements.
Start With Copy That Fits The Specs
Nailing the dimensions is half the battle; the words inside the frame do the selling, and they have to fit those ~125-character and ~27-40-character limits.
