The Power of 4:5 Vertical Posts on Instagram

A 4:5 vertical post (1080 × 1350 pixels) is the tallest format allowed in the Instagram feed. It occupies almost the entirety of the mobile phone screen as users scroll, giving your photo 37% more visual space than a square post and 139% more than a landscape post.

Using PixEnhance to fit landscape photos into 4:5 vertical canvas with blurred borders gives you maximum screen dominance without cropping out details.
