Does the iPad 6 fit into 2017 iPad cases? Yes!The physical dimensions of the 6th-generation iPad are exactly the same as the 5th-generation iPad. You don't have to buy a new case (unless you want to).
Great news! I can confirm that the latest and greatest 2018 9.7-inch iPad is exactly the same size and weight as the 2017 9.7-inch iPad, so there will be no issues with trading cases, buying up, or getting your older brother's hand-me-downs.
The 2018 iPad, available in silver, gold, and space gray is the same, down to the millimeter and gram, as it's predecessor.
