Instagram grid image size
Instagram’s profile grid shows square tiles. A reliable source size is a square master of at least 3240×3240 pixels, which cuts into nine 1080×1080 tiles — the long-standing recommended Instagram photo size. Larger masters still help if you crop.
Gridcut cuts whatever you give it into equal squares (it uses the largest square-able area from the source’s width and height divided by three). For a full-bleed puzzle, start with a square photo. A portrait photo will be sliced into squares from the top-left of each cell, so crop it square first if the edges matter.
