Nine-Grid Photo Split for Social Feeds

Why make a grid collage

In Xiaohongshu, Instagram and friend feeds, an image sliced into tiles takes over much more screen space and creates a satisfying reveal when swiping. It works well for product teasers, campaign posters and profile decoration.

Preparing the source image

• Ratio: a square master for 9-grid, 3:1 for a 3-tile row, 3:2 for 6 tiles
• Resolution: each tile should be at least 1080x1080, so aim for a master around 3240x3240
• Safe margins: keep key text and faces at least one tile away from cut lines
• Visual center: place focal points near the four grid intersections so each tile works alone

Online splitting steps

1. Open the image splitter and upload the master
2. Choose the grid: 2, 3, 4, 6 or 9
3. Preview the cut lines; make sure no text or face is sliced
4. Export all tiles, named in order

Publishing order is the common mistake

Platforms display multiple images in selection order. Rehearse in drafts:

• 9-grid: left to right in the first row, then row by row downward
• 3-tile row: left, center, right
• Save files in a folder numbered 1-9

Fixing tiles afterward

If one tile is poorly framed, trim it with the image cropper and re-split. If the master is low resolution, re-export it at 2K/4K with the AI image editor first so tiles stay sharp.
