Facebook Ad Sizes Cheat Sheet 2026 (All Placements)

Three Facebook ad sizes cover almost every placement in 2026: 1080x1080 (1:1) for carousels, Right Column, and Marketplace, 1440x1800 (4:5) for Facebook and Instagram feeds, and 1080x1920 (9:16) for Stories and Reels, where Meta now recommends up to 1440x2560. Every spec below was checked against Meta's official ads guide in July 2026.

The 3 Facebook Ad Sizes That Cover Every Placement

Produce these three masters and you can adapt to everything Meta sells:

• Master size — Aspect ratio — Covers
• 1440x1800 — 4:5 — Facebook Feed, Instagram Feed (Meta's recommended feed ratio)
• 1080x1920 or 1440x2560 — 9:16 — Facebook/Instagram Stories, Facebook/Instagram Reels
• 1080x1080 — 1:1 — Carousel cards, Right Column, Marketplace, feed fallback

Two practical notes before the placement-by-placement tables:

• 4:5 beats 1:1 in feeds. Meta's ads guide lists 4:5 as the recommended feed ratio for both image and video. Taller creative occupies more mobile screen per impression at the same price.
• Design 9:16 once, reuse everywhere vertical. Stories and Reels share dimensions and safe zones, so one vertical master covers four placements.

Facebook Feed Ad Sizes

The feed is still the highest-volume placement, and it is where wrong ratios hurt most.

• Spec — Image — Video
• Recommended ratio — 4:5 — 4:5
• Recommended resolution — 1440x1800 — 1440x1800
• File types — JPG, PNG — MP4, MOV, GIF
• Max file size — 30MB — 4GB
• Minimum size — 600x750 — 120x120
• Duration — n/a — 1 second to 241 minutes
• Ratio tolerance — 3% — 3%

Meta recommends keeping primary text between 50 and 150 characters and headlines within 27 characters for feed placements. Longer primary text still runs, it just truncates behind "See more," so put the hook in the first line. If your first line is not doing that job, fix it before you fix your dimensions: real examples in the Facebook ad hook examples post.

Video files should use H.264 compression, square pixels, fixed frame rate, and stereo AAC audio at 128kbps or higher.

Facebook Ad Sizes for Stories and Reels (9:16)

All four vertical placements take the same full-screen creative.

• Placement — Ratio — Recommended resolution — File types — Max size
• Facebook Stories (image) — 9:16 — 1440x2560 — JPG, PNG — 30MB
• Instagram Stories (image) — 9:16 — 1440x2560 — JPG, PNG — 30MB
• Facebook Reels (video) — 9:16 — 1440x2560 — MP4, MOV, GIF — 4GB
• Instagram Reels (video) — 9:16 — 1440x2560 — MP4, MOV — 4GB

The long-standing 1080x1920 standard still uploads fine (minimum width is 500 pixels), but Meta's ads guide now lists 1440x2560 as the recommended resolution, so export at the higher size if your source files allow it.

Reels-specific rules worth knowing: Instagram Reels ads run up to 15 minutes, sound is "optional, but strongly recommended," and licensed music is not allowed in ads, so use original audio or Meta's Sound Collection. Design for sound on; Reels is the one Meta surface where users expect it.

Safe zones: keep the top 14% and bottom 35% clear

Meta's official guidance for Stories and Reels: keep roughly 14% of the top, 35% of the bottom, and 6% of each side free of text, logos, and key creative elements. That is where the profile icon, caption, CTA button, and engagement rail sit. In pixels:

• Canvas — Top zone (14%) — Bottom zone (35%) — Each side (6%)
• 1080x1920 — top 270px — bottom 672px — 65px
• 1440x2560 — top 358px — bottom 896px — 86px

Everything that must be read (hook text, offer, product) lives in the middle band. The bottom third being off-limits surprises most first-time Reels advertisers; it is the single most common reason a strong hook goes unread.

Instagram Ad Sizes (Feed)

Instagram Feed shares the 4:5 recommendation but has its own limits, per Meta's Instagram Feed specs:

• Spec — Instagram Feed image
• Recommended ratio — 4:5
• Supported ratio range — 4:5 to 1.91:1
• Recommended resolution — 1440x1800
• Minimum width — 500px
• File types — JPG, PNG
• Max file size — 30MB
• Ratio tolerance — 1%
• Max hashtags — 30

Meta's recommended text lengths here are 125 characters of primary text and a 40-character headline. Note the tighter 1% ratio tolerance versus Facebook Feed's 3%: crop precisely rather than trusting the uploader.

Right Column and Marketplace Ad Sizes

Two placements people forget until the crop looks broken:

• Spec — Right Column — Marketplace
• Ratio — 1:1 — 1:1
• Recommended resolution — at least 1080x1080 — at least 1080x1080
• File types — JPG, PNG — JPG, PNG
• Minimum size — 254x133 — n/a
• Where it shows — Desktop only — Facebook Marketplace browse

Right Column renders small, so Meta explicitly recommends not adding text on the image; let the 40-character headline do the work. It is a cheap desktop retargeting surface, not a storytelling one. Marketplace supports 125 characters of primary text, a 40-character headline, and a 30-character description. Specs: Right Column and Marketplace.

Carousel Ad Sizes

Carousels use square cards everywhere, per Meta's carousel specs:

• Spec — Carousel
• Cards — 2 to 10
• Ratio — 1:1
• Resolution — at least 1080x1080
• Image max size — 30MB per card
• Video max size — 4GB per card
• Video duration — 1 second to 240 minutes

Meta recommends about 80 characters of primary text, and each card carries its own headline, description, and landing URL. Keep card headlines very short; they truncate aggressively under square cards.

File Size Limits and Text Lengths: Quick Reference

The numbers that answer 90% of "will this upload?" questions:

• Limit — Value
• All image ads, max file size — 30MB
• All video ads, max file size — 4GB
• Image file types — JPG, PNG
• Video file types — MP4, MOV (GIF on some placements)
• Video encoding — H.264, square pixels, fixed frame rate, AAC 128kbps+
• Vertical (9:16) minimum width — 500px

On text: Meta's character recommendations shift by placement and objective (feed headlines 27, Instagram and Stories 40, carousel cards shorter still). The universal safe rule is a hook-first primary text under 125 characters and a headline under 27, which fits every placement without truncation.

The 15-Minute Export Checklist

Before any campaign goes to upload, run the batch through this:

1. Three masters exported: 1440x1800 (4:5), 1080x1920 or 1440x2560 (9:16), 1080x1080 (1:1), all from the same design file.
2. Safe zones checked on the 9:16 master: nothing readable in the top 14% or bottom 35%. Drop Meta's zones as a guide layer in Figma or Photoshop once and reuse it forever.
3. File formats right: JPG or PNG for statics, MP4 or MOV with H.264 and AAC audio for video.
4. Resolution at or above recommended, not scraping the minimum.
5. Placement customization mapped in Ads Manager: 4:5 to feeds, 9:16 to Stories and Reels, 1:1 to carousel, Right Column, and Marketplace.
6. First line of primary text carries the hook, since everything after roughly 125 characters truncates on most placements.

Ten minutes of checklist beats a week of "why is our Reels CTR terrible" archaeology.

Common Facebook Ad Size Mistakes

These come up in almost every account audit:

1. Running 16:9 horizontal creative in mobile feeds. A 4:5 creative takes up nearly twice the vertical screen of a 16:9 one. Save the wide format for in-stream video, nowhere else.
2. Text in the Reels bottom zone. The bottom 35% sits under the caption, CTA, and engagement buttons. If your offer or subtitle lives there, it was never seen.
3. One 1:1 asset for every placement. Square gets letterboxed in Stories and Reels, shrinking your ad to a third of the screen. Use Ads Manager's placement customization (Meta calls it placement asset customization) to assign the 9:16 master to vertical surfaces.
4. Uploading below minimum resolution. Meta upscales small files and they come out soft. Export at the recommended resolution, not the minimum.
5. Still designing around the "20% text rule." Meta retired the automated text-overlay penalty years ago. Text-heavy statics are allowed and often win; what matters is legibility at thumb-scroll speed, not an arbitrary percentage.
6. Licensed music in Reels ads. It is a rejection waiting to happen. Use original audio or Meta's Sound Collection.

FAQ

What is the best Facebook ad size in 2026?

There is no single size, but 1440x1800 (4:5) is the best default for feed placements and 1080x1920 or 1440x2560 (9:16) for Stories and Reels. Keep a 1080x1080 (1:1) version for carousels, Right Column, and Marketplace, and you have every placement covered.

Should Facebook feed ads be 1:1 or 4:5?

Meta's ads guide recommends 4:5 for both image and video feed ads, at 1440x1800. A 4:5 creative fills noticeably more mobile screen than a square at the same auction price. Keep 1:1 only as a fallback and for placements that require it, like carousels.

What are the safe zones for Facebook Reels ads?

Meta recommends keeping about 14% of the top, 35% of the bottom, and 6% of each side free of text, logos, and key elements. On a 1080x1920 canvas that means the top 270px and bottom 672px. Put hooks and offers in the middle band.

What is the maximum file size for Facebook ads?

Image ads accept up to 30MB in JPG or PNG format. Video ads accept up to 4GB in MP4 or MOV (GIF works on some placements), using H.264 compression with stereo AAC audio at 128kbps or higher. Feed videos can run up to 241 minutes, though almost no ad should.

Do Instagram and Facebook Stories ads use the same size?

Yes. Facebook Stories, Instagram Stories, Facebook Reels, and Instagram Reels all take 9:16 creative with a recommended resolution of 1440x2560, and they share the same safe zones. One vertical master, exported once, covers all four placements without any recropping.
