Overview

• The feature launched May 29 and is now rolling out to all users, though visibility may vary.
• Photos shot in a 3:4 ratio will display exactly as captured without cropping or black bars.
• The new format applies to both single-image posts and carousel uploads.
• Instagram previously limited vertical photos to a 4:5 ratio, which trimmed the top or bottom of 3:4 images.
• Some users are already requesting support for other popular ratios, such as 2:3, to enhance flexibility.
