Why Correct Image Sizing Matters on Facebook
Optimizing image size for Facebook’s multi-photo posts impacts both presentation and performance:
- Higher Engagement – Well-sized images attract more likes, shares, and comments.

- Algorithm-Friendly – Posts with stronger engagement often receive better placement in feeds.
Accurate sizing also means your content is displayed as intended, fostering trust and encouraging repeat interaction.

General standards (2024):

Recommended Dimensions for Each Orientation

Best Practices for Mixing Image Orientations
- Pick a primary orientation – Keep most images vertical or square for visual consistency
- Lead with impact – Put your most striking image first in sequence
- Avoid extremes – Ultra-wide panoramas often lose impact in grids
- Ensure color harmony – Unified color palettes enhance cohesion

How Cropping Works in Facebook’s Multi-Image Grid
Facebook automatically crops images to fit its templates, potentially trimming important parts.
Tips to prevent awkward cuts:
- Keep focal points centered
- Leave space around text
- Test in a draft or preview mode
- Avoid placing essential elements at the edges

Mobile vs. Desktop Display Differences
Mobile
- Vertical formats fill more vertical space

Optimize according to where your target audience browses most.
