Why files fail on Instagram

Many guides still say 4:5 (1080 × 1350), but Instagram now allows feed photos as tall as 3:4. Taller photos than that are cropped automatically.

What this preset does

This preset crops to 3:4 and resizes to exactly 1080 × 1440, the most screen space a feed photo can take.

Questions

Is 4:5 still the tallest Instagram size?
No. Instagram's help center now lists 3:4 (1080 × 1440) as the tallest feed shape.
What if my photo is landscape?
This preset crops the sides. For landscape photos, the square post preset keeps more of the image.
Does this work for carousels?
Yes, but every photo in a carousel shares the first photo's shape.
