The Pinterest Square Pin size (1000×1000px)
A square pin at 1000x1000 pixels is a solid Pinterest alternative to the tall 2:3 format. While vertical pins usually dominate the feed, squares have their place: they suit product shots, recipe cards, and collage or grid layouts where a balanced 1:1 composition simply looks better than a stretched vertical.
Squares take less vertical space than 2:3 pins, so they are a bit less commanding in the masonry grid, but they are also versatile. The same 1000x1000 graphic can be repurposed as an Instagram post or a general social square, which makes it efficient when you are producing content for several platforms at once.
As with any pin, keep text overlays large and legible for mobile and avoid crowding the bottom edge where the pin title and source attribution appear. Because a square gives you less height for stacked text than a tall pin, favor a short punchy headline over multiple lines. Clear, high-contrast typography on a strong image keeps square pins competitive.
