Twitter has rolled out support for images in different aspect ratios, which means your images will no longer be cropped to 16:9 on the timeline.
In a tweet the company confirmed:
no bird too tall, no crop too short
introducing bigger and better images on iOS and Android, now available to everyone
Twitter confirmed that images with 2:1 and 3:4 aspect ratios will now be displayed in full on the timeline when viewed by users, rather than as a cropped preview.
Twitter announced this and 4K image support earlier this year. From that report:
Sometimes it’s better said with a picture or a video. Over the next few weeks, we’ll be testing some ways to improve how you can share and view media on Twitter. Now testing on Android and iOS: when you Tweet a single image, how the image appears in the Tweet composer is how it will look on the timeline –– bigger and better.
Have a collection of higher res photos waiting to be shared? We’re testing ways for you to upload and view 4K images on Android and iOS.
If you’re in the test, update your high-quality image preferences in “Data usage” settings to get started.
Earlier this week it was announced Twitter had acquired Scroll, and would be integrating the service as part of a subscription option later this year.
Going forward, Twitter users can now take advantage of 4K image uploads and lots of different aspect ratios, enjoy!
