Facebook 2026: The Complete Guide to Image and Ad Sizes
At LOOK_LIKE, we know that the chaos of Facebook formatting can be overwhelming. In 2026, Meta's algorithms prioritize clarity and mobile responsiveness. If your graphics are sized incorrectly, Facebook will crop or blur them, significantly lowering your campaign's effectiveness.
Here are the current specifications we use for our projects:
1. Feed Posts
Standard posts are the backbone of your communication. On Facebook, readability on smartphones is everything.
- Vertical Post (4:5) – RECOMMENDED: 1080 x 1350 px
- Why? Much like on Instagram, this format occupies the most space in the mobile feed.
- Square Post (1:1): 1080 x 1080 px
- Landscape Post (1.91:1): 1200 x 630 px (Primarily used for sharing links).
2. Cover Photos
This is your brand's storefront. Remember that cover photos display differently on desktop versus mobile devices.
- Profile Cover Photo: 820 x 312 px (Desktop) / 640 x 360 px (Mobile)
- LOOK_LIKE Pro-tip: Use 820 x 462 px and keep a safe margin at the top and bottom (place text centrally) to ensure the graphic looks perfect on both devices.
- Group Cover Photo: 1640 x 856 px
- Event Cover Photo: 1200 x 628 px
3. Facebook Stories and Reels
Full-screen video and image formats that currently dominate content consumption.
- Dimensions: 1080 x 1920 px (9:16 aspect ratio).
- Safe Zone Rule: Just like on IG, avoid placing text in the top and bottom 250 px—this is where app interface elements (like buttons and icons) are located.
4. Facebook Ads
When we run a campaign for you, we prepare assets in the following formats:
- Carousel Ads: 1080 x 1080 px for each image (must maintain the same ratio for all cards).
- Right Column Ads (Desktop): 1200 x 1200 px.
- Facebook Marketplace: 1200 x 1200 px.

Technical Notes from the LOOK_LIKE Webmaster:
- Text on Graphics: Although the official "20% text" rule no longer strictly blocks ad delivery, Facebook still favors graphics with minimal text in terms of reach.
- File Formats: Use PNG for graphics with flat colors and logos (to avoid artifacts). Use JPG for high-quality photographs.
- File Weight: Keep your files under 1 MB. Even within the Facebook app, loading speed matters for user retention.
