About this size

The 250 by 250 square is the larger of the two standard square ad formats. The extra 50 px in each dimension gives a noticeable amount of layout room compared to small square, enough to support a stronger visual hierarchy without becoming as horizontal as Medium Rectangle.

It is most often used as a square companion to the standard rectangle formats in ad sets that need a 1:1 option.

Pro tips

1 One message, one CTA. The format is slightly larger than small square but still demands layout discipline.
2 Use as a square companion to Medium and Large Rectangle in mixed ad sets. The format choice signals the placement context.
3 High-contrast typography wins at this size. Reserved styling competes with the article content the ad serves alongside.
