Facebook automatically creates photo collages when you upload multiple images to a post. But creating your own collage image before posting gives you full control over the layout, cropping, and visual impact — resulting in a more polished, intentional-looking post.
Facebook Image Collage Sizes
| Use | Recommended Size |
|---|---|
| Facebook post (horizontal) | 1200×630 px |
| Facebook post (square) | 1080×1080 px |
| Facebook story | 1080×1920 px |
Creating a Facebook Post Collage Free
Visit imgresizr.com and open the Collage tool. Choose your canvas size — 1200×630px for a landscape post or 1080×1080px for a square post. Select a grid layout: 2-column, 3-column, or custom arrangement. Upload your photos and position them in each grid cell. Apply consistent borders, colour accents, or a text overlay headline. Download as JPG and upload as a single image to your Facebook post — you maintain full control over how it displays.
Facebook Collage Layout Ideas
- 2×2 grid: 4 photos of equal size — events, products, team
- 1 large + 2 small: hero image with supporting context shots
- 3-column horizontal: timeline or comparison layouts
- Mosaic: irregular sizes for a magazine-style feel
Facebook Collage Performance Tips
- Include people in at least one photo — Facebook's algorithm favours images with faces
- Use bright colours — they stop the scroll in Facebook's busy timeline
- Add a caption text overlay with your key message — many users scroll without reading
