In landscape the iPad trims the sides, so it looks best when you hold the iPad upright.
Instagram
- Use Insta post (4:5) for the feed. It fills the post with no cropping.
- Use Insta story (9:16) for stories and reel covers.
- Put your own name or handle as the signature before you share.
In stories, Instagram puts your name at the top and the reply box at the bottom, so keep key words in the middle.
