Apple has posted detailed official dimensional drawings for the iPad mini — Wi-Fi and Wi-Fi + Cellular versions — on its website, and has done the same for the fourth-generation iPad (Wi-Fi and Wi-Fi + Cellular).

All of the documents are available through Apple’s developer portal. Although they don’t reveal any new information, the measurements enable accessory designers to proceed with their new products, particularly cases that depend upon precise measurements. Apple released drawings for the iPhone 5, new iPod touch, and new iPod nano in September.
