Some images work naturally as squares: a plate viewed from above, a compact product arrangement, a face, or a finished illustration. Forcing those images into a tall frame can remove useful detail or create a composition that feels cramped. A square export gives you a consistent version without pretending that every Pinterest image needs the same shape.
The 1000×1000 dimensions on this page are our preset choice. Pinterest's general creative guidance highlights vertical 2:3 imagery, so a square should be a deliberate alternative based on your artwork and publishing context. Check the current Pin preview rather than assuming a square guarantees any particular feed treatment.
Start by identifying the image's visual centre. A round plate may already sit in the middle, while an asymmetrical object can look off balance even when its bounding box is centred. Leave enough space around the subject that the crop feels intentional and the image remains useful when displayed smaller.
