How much storage you need depends on how you use your iPad. More room means you can store more apps, music, movies, and books. It also lets you store RAW images, 4K videos, 3D renders, illustrations, and other large files.
Over time you may add more content to your iPad, so you’ll want to think about how your storage needs may change.
Storage is measured in gigabytes (GB) and terabytes (TB).
Note: Available space is less and varies due to many factors. Storage capacity subject to change based on software version, settings, and iPad model. 1GB = 1 billion bytes; 1TB = 1 trillion bytes. Actual formatted capacity less.
