The image-sharing service now lets you go wide—or tall—for photos and videos that don’t fit into its iconic square frame.
In its own way, it’s been as defining a restriction as Twitter’s 140-character limit. Instagram photos (and videos) come in one format: square. It forces the service’s photographers into choosing thoughtful compositions, and provides an aesthetic link to the square snapshots that folks once took with Instamatics and Polaroids.
