Facebook Post, Reel & Story Sizes: Every Dimension for 2026
Getting Facebook image sizes wrong costs you reach. Upload the wrong dimensions and your cover photo gets cropped, your feed post looks blurry, and your ad underperforms because it looks unprofessional in the auction.
This guide covers every Facebook image and video dimension you need in 2026 — feed posts, Reels, Stories, cover photos, profile pictures, event banners, group headers, and ads. Bookmark it and come back whenever you need a quick reference.

Quick Reference Table
Here is the cheat sheet. For detailed specs, file size limits, and safe zones, see each section below.
| Placement | Dimensions (px) | Aspect Ratio |
|---|---|---|
| Feed post (portrait) | 1080×1350 | 4:5 |
| Feed post (square) | 1080×1080 | 1:1 |
| Feed post (landscape) | 1200×630 | 1.91:1 |
| Link share image | 1200×630 | 1.91:1 |
| Stories | 1080×1920 | 9:16 |
| Reels | 1080×1920 | 9:16 |
| Cover photo | 851×315 | 2.7:1 |
| Profile photo | 320×320 | 1:1 |
| Event cover | 1920×1005 | 1.91:1 |
| Group cover | 1640×856 | 1.91:1 |
Key takeaway: Portrait (4:5) at 1080×1350 is the best default for feed posts. It takes up the most screen space on mobile, which is where the majority of Facebook users browse.
Feed Post Dimensions
Facebook feed posts support three main aspect ratios. Portrait takes up the most screen real estate on mobile and consistently outperforms the others for engagement.
| Placement | Dimensions (px) | Aspect Ratio | Max File Size | Format |
|---|---|---|---|---|
| Portrait (recommended) | 1080×1350 | 4:5 | 30 MB | JPG, PNG |
| Square | 1080×1080 | 1:1 | 30 MB | JPG, PNG |
| Landscape | 1200×630 | 1.91:1 | 30 MB | JPG, PNG |
| Link share image | 1200×630 | 1.91:1 | 30 MB | JPG, PNG |
Facebook adopted the 4:5 ratio from Instagram for feed display. Vertical images now fill significantly more of the mobile viewport than the old 1200×630 landscape standard that dominated for years.
For link shares, Facebook pulls the og:image from your URL. Make sure your website's open graph image is at least 1200×630px. If you are sharing blog posts or product pages, getting this right means your links look professional in the feed. Use our free UTM link builder to track clicks from your Facebook posts.
If you manage multiple Facebook accounts, a social media scheduler lets you prepare all your posts in advance. Check out our guide on the best time to post on Facebook to maximise reach.
Reels Dimensions
Since June 2025, all Facebook videos are Reels. There is no separate "video post" format. If you upload a video to Facebook — whether through the app, Creator Studio, or a Facebook scheduler — it becomes a Reel automatically.
| Placement | Dimensions (px) | Aspect Ratio | Max Duration | Format |
|---|---|---|---|---|
| Reels | 1080×1920 | 9:16 | 15 minutes | MP4, MOV |
| Reels cover image | 1080×1920 | 9:16 | N/A | JPG, PNG |
Safe zone: Keep all text and important elements within the centre 1080×1420px area. The top and bottom of the frame are covered by the username bar, captions, and engagement buttons.
Upload at full 1080×1920 resolution. Facebook's algorithm deprioritises blurry or low-resolution video, so starting with the correct dimensions matters for distribution. For tips on cross-posting your Reels to Instagram simultaneously, read our guide on cross-posting.
Stories Dimensions
Facebook Stories use the same 9:16 vertical format as Reels, but they are temporary (they disappear after 24 hours) and have different duration limits.
| Placement | Dimensions (px) | Aspect Ratio | Max Duration | Format |
|---|---|---|---|---|
| Image Story | 1080×1920 | 9:16 | 26 seconds | JPG, PNG |
| Video Story | 1080×1920 | 9:16 | 60 seconds | MP4, MOV |
Safe zone: Keep important content within the centre 1080×1680px area. The top 150px and bottom 90px are covered by your profile name, stickers, and reply buttons.
Stories are a great format for time-sensitive promotions and behind-the-scenes content. Use PostEverywhere's social media calendar to plan your Story content alongside your feed posts.
Cover Photo Dimensions
Your Facebook cover photo is the first thing visitors see when they land on your Page. It displays differently on desktop and mobile, so you need to design with both in mind.
| Placement | Dimensions (px) | Aspect Ratio | Notes |
|---|---|---|---|
| Cover photo (upload) | 851×315 | 2.7:1 | Recommended upload size |
| Desktop display | 820×312 | — | Slightly cropped from upload |
| Mobile display | 640×360 | — | Top and bottom are more visible |
| Safe zone | 820×360 | — | Keep critical content inside this area |
Upload at 851×315 minimum, but 1640×624 is better for high-resolution (Retina) displays. Keep all text and logos within the centre 640×312px to avoid cropping on any device.
According to Meta's help centre, cover photos load fastest when they are sRGB JPG files under 100KB. If your cover includes a logo with sharp edges, PNG will preserve quality better but load slightly slower.
Profile Photo Dimensions
| Placement | Dimensions (px) | Display Size | Format |
|---|---|---|---|
| Profile photo | 320×320 (min) | 170×170 on desktop, 128×128 on mobile | JPG, PNG |
Upload at least 320×320, though 800×800 gives the sharpest result on high-density screens. Your profile photo displays as a circle, so keep your logo or face centred and away from the edges.
If you manage multiple Facebook accounts, consistency in profile images builds brand recognition across all your Pages.
Event Cover Photo Dimensions
| Placement | Dimensions (px) | Aspect Ratio | Format |
|---|---|---|---|
| Event cover | 1920×1005 | 1.91:1 | JPG, PNG |
| Minimum size | 1200×628 | 1.91:1 | JPG, PNG |
Facebook updated event cover dimensions to 1920×1005 in 2024. Over 70% of event views happen on mobile, so this size was specifically chosen to look good on smaller screens. According to Facebook's event help page, the cover displays differently across devices, so keep key details centred.
Group Cover Photo Dimensions
| Placement | Dimensions (px) | Aspect Ratio | Notes |
|---|---|---|---|
| Group cover | 1640×856 | 1.91:1 | Full upload size |
| Desktop display | 820×312 | — | Cropped from centre |
| Mobile display | 640×360 | — | Wider vertical crop |
| Safe zone | 640×312 | — | Keep all important content here |
The outer edges (approximately 90 pixels on each side) get cropped on mobile, so keep your important content well within the centre. Group covers are a good place for community guidelines, event announcements, or brand messaging.
Ad Dimensions
Facebook ads have their own dimension requirements. Uploading at the right size prevents Meta's ad system from compressing your creative during delivery.
| Placement | Dimensions (px) | Aspect Ratio | Format |
|---|---|---|---|
| Feed ad (single image) | 1080×1080 or 1080×1350 | 1:1 or 4:5 | JPG, PNG |
| Carousel ad (per card) | 1080×1080 | 1:1 | JPG, PNG |
| Stories / Reels ad | 1080×1920 | 9:16 | JPG, PNG, MP4 |
| Right column ad | 1080×1080 | 1:1 | JPG, PNG |
| Video ad | 1080×1080 or 1080×1920 | 1:1 or 9:16 | MP4 (H.264, AAC) |
Carousel ads support between 2 and 10 cards per carousel. Each card should be 1080×1080 (square). According to Meta's ads guide, 3 to 5 cards typically perform best for engagement.
Video ads should use H.264 video codec with AAC audio. Keep file size under 4 GB and use MP4 format. For carousel video cards, 15-second clips perform best. For feed video ads, portrait (4:5) or square (1:1) outperforms landscape because of how the mobile feed is structured.

Tips for Facebook Image Optimisation
1. Default to Portrait (4:5) for Feed Posts
Portrait images take up significantly more screen space on mobile than square or landscape. Since the vast majority of Facebook users browse on their phones, 1080×1350 should be your default for organic feed content.
2. Use the Right Format
Use JPG for photographs — it keeps file sizes manageable. Use PNG for graphics with text, logos, or transparency. For video, MP4 with H.264 encoding is universally supported.
3. Design Cover Photos for Both Desktop and Mobile
Your cover photo crops differently on each device. Always use the safe zone (centre 640×312px) for critical content. Test how it looks on both desktop and mobile before publishing.
4. Upload Higher Resolution for Ads
Organic posts at 1080px wide look great. Ads go through additional compression during delivery, so starting at higher resolution gives you a quality buffer. Meta accepts images up to 30 MB, so there is no reason to over-compress.
5. Automate Your Resizing
If you are posting the same content to Facebook, Instagram, LinkedIn, and other platforms, manually resizing for each one wastes time. PostEverywhere's image resizer and automatic optimisation handle this for you. You can also use our AI Image Generator to create visuals at the exact dimensions you need.
