The new Instagram grid is 1080×1350. Here's everything that changed.
The new Instagram grid size is 1080×1350px (4:5 portrait) — Instagram changed from the classic 1:1 square in 2024. In August 2025, Instagram added support for an even taller 3:4 format (1080×1440px). Exact pixel sizes, what changed, and how to preview your posts in both old and new grid sizes before posting.
Use 1080×1350px (4:5) for the broadest compatibility across every app and scheduler.
The new Instagram grid size is 1080 × 1350 px (4:5 portrait) — changed from the old 1:1 square in 2024. As of August 2025, Instagram also supports 1080 × 1440 px (3:4), an even taller option not yet supported by most scheduling tools.
Instagram grid formats — at a glance
The shift from square to portrait isn't a small visual tweak. Each tile shows more vertical space, which means your composition, color flow, and crop logic all need to follow.
Note: Landscape posts are center-cropped to 4:5 on your profile grid, so only the middle portion shows when someone views your profile. The grid display tile is rendered at approximately 1013×1350 px — this is the preview size, not the upload size.
Try every ratio, see the safe zone, and what gets cropped.
In 2024, Instagram switched the default grid size from a 1:1 square to a 4:5 portrait rectangle. The new grid means each photo on your profile takes up more vertical space. Toggle below to see exactly how the same photo behaves in each format.
Same photo, three formats.
The motivation behind the new grid was to align with how people actually shoot on their phones — portrait by default. A 4:5 grid also shows more of each image, reducing content lost to cropping compared to the old square.
You're not alone. Instagram rolled out gradually.
If your IG grid still shows square tiles after the update, the timing varied across accounts and regions. Here are the four most common reasons.
Regional rollout
Instagram released the change in waves across different countries and regions. Some markets received it months later than others.
Account type
Personal, creator, and business accounts sometimes receive feature rollouts at different speeds. Business accounts were often last.
Old app version
If you haven't updated the Instagram app recently, you may still be seeing the old square grid layout. Update to see the current format.
Old posts stay cropped
Posts you uploaded before the grid size change were not automatically re-cropped. They keep their original crop on your IG grid.
Half your followers see the old grid. Half see the new.
Because Instagram's rollout was gradual, your audience is split right now. Followers on updated apps see your profile in 4:5 portrait. Everyone else still sees 1:1 square tiles. The same photo can look very different depending on who's viewing.
Tall portrait shots that look great in 4:5 may appear awkwardly cropped in 1:1, and vice versa. If you're planning a visually cohesive feed, you need to think about both.
Preview in both formats →Most planning tools are still stuck in the square era.
You spend time arranging photos, checking color flow, sequencing posts — but your tool still previews 1:1 tiles. When you actually post, followers on updated apps see 4:5, and the layout you planned looks completely different.
Grid34Sync previews your feed in the actual 4:5 portrait format Instagram uses today. Drag photos to rearrange, see exactly how your profile looks to followers right now — then switch to 1:1 mode to check older app versions. Both formats, one tool.

How to optimize photos for the new grid size.
Photos cropped tightly for a square may lose important parts of the composition at top or bottom in 4:5. Here's how to adapt.
Shoot in 4:5 from the start
Set your phone camera to the new ratio. Most modern iPhones and Androids support it natively — no cropping later.
Keep subjects in the center safe zone
Keep the main subject within the central square area. It stays visible in both 4:5 and 1:1.
For carousels, optimize slide one
Only the first slide is visible as a tile. Focus your safe-zone composition there. Other slides can use the full frame.
How carousel posts work →Add padding around borders
If your design touches the edges, add a small buffer of empty space. This prevents tile cropping and adds breathing room.
Preview in both grid sizes
Toggle between 4:5 and 1:1 before posting. Color flow, balance, and sequence read differently in each format.
