Display:The displays have rounded corners. When measured diagonally as a rectangle, the iPad Pro 12.9-inch screen is 32.77 centimetres (12.9 inches), the iPad Pro 11-inch screen is 27.96 centimetres (11 inches), the iPad Air (4th generation) screen is 27.59 centimetres (10.86 inches) and the iPad mini (6th generation) screen is 21.08 centimetres (8.3 inches). Actual viewable area is less.
Capacity: Available space is less and varies due to many factors. A standard configuration uses approximately 10GB to 13GB of space (including iPadOS and pre-installed apps) depending on the model and settings. Pre-installed apps use about 4GB, and you can delete these apps and restore them. Storage capacity is subject to change based on software version and may vary by device.
Cellular and Wireless: Data plan is required. 5G, Gigabit LTE, Gigabit-class LTE, 4G LTE Advanced, 4G LTE and Wi-Fi calling are available in selected markets and through selected carriers. Speeds are based on theoretical throughput and vary based on site conditions and carrier. For details on 5G and LTE support, contact your carrier and see apple.com/in/ipad/cellular.
