Instagram's New Grid Layout (2025-2026 Change)

What changed: Instagram now displays profile grid previews in a taller 3:4 aspect ratio instead of the old square 1:1 format.

Old vs. New Grid Preview

What This Means for Grid Posts

The challenge: Traditional square grid splitters create 1:1 images, but Instagram now shows a taller preview. Your split images may appear cropped or misaligned.

The solution: You have two options:

Option 1: Use 4:5 ratio images (recommended)

• Create your grid using 1080 × 1350px tiles instead of squares
• Total image size for 3×3 grid: 3240 × 4050px
• Looks perfect on the new grid layout

Option 2: Add margins to square images

• Add 32.5px vertical margins to each side of square images
• This centers the square within the 3:4 preview frame
• Good for adapting existing square content

What Are Instagram Grid Posts?

Why Use Grid Posts?

Increased Profile Visits

Grid posts encourage users to visit your profile to see the complete image, increasing engagement.

Higher Engagement

Multiple posts from one image increase your visibility in feeds and can boost overall engagement rates.

Brand Storytelling

Create impactful brand narratives and showcase products/services across multiple grid squares.

Grid Post Best Practices & Strategy

Content Strategy for Grid Posts

✅ What Works Best:

• Product showcases: Display products across multiple angles
• Behind-the-scenes: Show process or workspace panoramas
• Quote graphics: Split inspirational or educational content
• Event coverage: Create story arcs across multiple posts
• Tutorials: Break down step-by-step processes

❌ What to Avoid:

• Overuse: More than 1-2 grid posts per week
• Low resolution: Images under 1080×1080px per square
• Text-heavy images: Hard to read when split
• Complex compositions: Images that don't work when separated
• Posting out of order: Ruins the visual effect

Strategic Posting Guidelines

Posting Order

Always post from right to left, bottom to top. This ensures the image appears correctly when viewed on profiles.

3×3 Order:

9→8→7
6→5→4
3→2→1

Timing Strategy

Post all grid pieces within 10-15 minutes for maximum algorithm benefit. Use scheduling tools for precision.

Tip: Schedule during your peak engagement hours for best results.

Caption Strategy

Use the first post for your main message and call-to-action. Keep other captions minimal or use arrow emojis pointing to the main post.

Example: "👈 See main post for details"

Common Grid Post Mistakes to Avoid

Mistake 1: Not Accounting for the New Grid Ratio

Problem: Using old square (1:1) splitters without adjusting for Instagram's 3:4 preview. Solution: Use 4:5 ratio images (1080×1350px per tile) or add margins to center square content.

Mistake 2: Posting in the Wrong Order

Problem: Posting images from left to right or top to bottom scrambles the grid. Solution: Always post right to left, bottom to top. For 3×3: post positions 9→8→7→6→5→4→3→2→1.

Mistake 3: Low Resolution Images

Problem: Using images smaller than 1080px per tile results in blurry posts. Solution: Start with high-resolution source images. For a 3×3 grid, your original should be at least 3240×4050px.

Mistake 4: Waiting Too Long Between Posts

Problem: Spreading grid posts over hours or days reduces algorithm boost and visual impact. Solution: Post all grid pieces within 10-15 minutes. Use a scheduling tool for precision.

Mistake 5: Complex Images That Don't Work When Split

Problem: Faces split awkwardly, text becomes unreadable, or important elements get cut off. Solution: Choose images with distributed visual interest. Test the split before posting.

Mistake 6: Overusing Grid Posts

Problem: Posting grids too frequently annoys followers and reduces impact. Solution: Limit to 1-2 grid posts per week maximum. Save them for impactful moments.

Frequently Asked Questions

What are the best dimensions for Instagram grid posts in 2026?

For 2026, use 4:5 ratio images (1080×1350px per tile) to match Instagram's new 3:4 grid preview. For a 3×3 grid, your total image should be 3240×4050px. Square images (1080×1080px) still work but may appear cropped in the grid preview.

Did Instagram change the grid layout?

Yes, Instagram changed the profile grid preview from a 1:1 square ratio to a taller 3:4 ratio in 2024-2025. Posts uploaded in 4:5 ratio (1080×1350px) display best on the new grid layout.

In what order should I post Instagram grid images?

Post from right to left, bottom to top. For a 3×3 grid, the posting order is 9-8-7 (top row), 6-5-4 (middle row), 3-2-1 (bottom row). This ensures the image appears correctly on your profile.

How often should I post Instagram grid posts?

Limit grid posts to 1-2 per week maximum. Overusing grid posts can overwhelm your audience and reduce their visual impact. Quality and strategic timing are more important than frequency.

Do Instagram grid posts hurt my algorithm performance?

No, when done correctly, grid posts can boost engagement and profile visits, which are positive signals for the algorithm. However, posting too many grid posts too quickly can be seen as spam.

What happens if I delete one piece of a grid post?

Deleting any piece will break the visual effect on your profile. The grid will no longer appear as a cohesive image. If you need to remove content, it's better to delete the entire grid.

Can I use the same hashtags on all grid post pieces?

Use your primary hashtags on all pieces for consistency, but you can vary 5-10 hashtags per post to reach different audiences while maintaining brand consistency and avoiding repetition penalties.

How long should I wait between posting grid pieces?

Post all grid pieces within 10-15 minutes for maximum algorithm benefit. Use scheduling tools for precision timing. Posting too far apart reduces the visual impact and algorithm boost.

What types of content work best for Instagram grid posts?

Product showcases, behind-the-scenes panoramas, quote graphics, event coverage, and tutorials work best. Avoid text-heavy images or complex compositions that don't work when split.

Should I write different captions for each grid post?

Use the first post for your main message and call-to-action. Keep other captions minimal or use arrow emojis (like "👈 See main post for details") pointing to the main post.
