Storage is measured in gigabytes (GB) and terabytes (TB), and the more your iPad has, the more room you have to store digital content like apps, music, movies, photos, books, and more. You’ll also have more room to store the content you create, including videos and photography, presentations, 3D renders, illustrations, and more. Over time you may add more content to your iPad, so you’ll want to think about how your storage needs may change.
Note: Available space is less and varies due to many factors. A standard configuration uses approximately 10GB to 13GB of space (including iPadOS and preinstalled apps) depending on the model and settings. Preinstalled apps use about 4GB, and you can delete these apps and restore them. Storage capacity subject to change based on software version and may vary by device.
