Getting an Instagram Grid Right

A grid mural only works if the maths lines up before you slice.

  1. Start with a perfect square. Crop it with the image cropper using the 1:1 preset.
  2. Make it 3240 x 3240 pixels, so each of the nine tiles lands at exactly 1080 x 1080.
  3. Split into 3 rows and 3 columns.
  4. Post the tiles in reverse order, bottom right first, so the grid assembles the right way up.
  5. Post all nine in one sitting. A half finished mural looks like a mistake in your feed.
Worth knowing: a grid mural locks those nine slots forever. Every future post pushes the mural down and eventually breaks it up. Plenty of accounts regret it after a month.

Doing It in GIMP

GIMP has this built in, and it handles uneven slices, which this tool does not.

  1. Open the image and add guides with Image > Guides > New Guide (by Percent), at 33 and 66 percent for a 3 x 3.
  2. Go to Filters > Web > Slice.
  3. Pick an output folder and a naming prefix.
  4. GIMP writes one image per region, plus an HTML table if you want one.

The advantage of guides is that they do not have to be evenly spaced, so you can slice a header, a body and a footer at their natural boundaries.

Common Questions

What if the image does not divide evenly?

The last row and column absorb the remainder, so no pixels are thrown away. Those tiles end up a few pixels larger than the rest.

Can I put the tiles back together?

Yes. The filenames carry the row and column, so open them all as layers in GIMP and place them on a grid. It is easier to keep the original file.

Does splitting lose quality?

Not with PNG. Choosing JPG re-compresses each tile once, which is fine for photos but shows on flat colour and text.
