Photo Grid for Instagram
Instagram is a visual platform — your grid layout matters more here than anywhere else. The most popular sizes for Instagram are:
Square Post1080×1080px
The classic Instagram format — perfect for 2×2 or 3×3 photo grids.
Portrait Post1080×1350px
Takes up more space in the feed — great for 2 or 3-photo vertical grids.
Story/Reel1080×1920px
Ideal for collages shared as Instagram Stories or Reels.
Photo Grid for Facebook
Facebook supports a variety of image sizes. For the best results:
Facebook Post1200×630px
Landscape format that works great for side-by-side photo grids.
Facebook Cover1920×721px
Wide banner format, perfect for panoramic or multi-photo covers.
Photo Grid for Pinterest

Tips for a Better Social Media Photo Grid
- Use consistent colors — matching borders and backgrounds make your grid look professional.
- Keep it simple — 2 to 4 photos per grid performs better than overcrowding.
- Use the right size — always match the grid size to the platform you're posting on.
- Add text sparingly — a short caption or label can help but don't overcrowd the image.
