iPad Pro 12.9-Inch Size and Dimensions Explained

iPad Pro 12.9-inch dimensions: 280.6 × 214.9 × 6.4 mm. Weight: 682 g.

The iPad Pro 12.9-inch measures 280.6mm x 214.9mm x 6.4mm and weighs about 682 grams, making it the largest tablet Apple offered before the 2024 lineup redesign, when this size was renamed to the 13-inch iPad Pro. In centimeters, that works out to roughly 28.1cm long and 21.5cm wide, close enough to a standard US Letter or A4 sheet of paper that most people picture its size just by comparing it to a notepad.

At 6.4mm thick, the 12.9-inch iPad Pro is noticeably chunkier than the newer 13-inch model, which slimmed the body down to 5.1mm. So if you’re comparing dimensions between an older 12.9-inch unit and a current-generation iPad Pro, expect the new one to feel visibly thinner in hand, even though the screen size barely changed.

Why the 12.9-Inch Size Matters

The 682-gram weight puts this model firmly in two-handed territory rather than something you’d casually hold while reading. That extra size and weight, however, came with a real advantage: enough screen space for genuine split-view multitasking, something the 11-inch iPad Pro couldn’t match as comfortably. This made the 12.9-inch model a favorite among designers, illustrators, and video editors who paired it with the Apple Pencil and Magic Keyboard as a laptop alternative.

How the iPad Pro 12.9-Inch Compares in Size

For a quick size reference, the 12.9-inch iPad Pro is close in length to an American football (280mm) and about 19mm shorter than a 12-inch vinyl record (300mm). It’s also nearly identical in length to a US Letter sheet (279.4mm), just slightly shorter than an A4 sheet (297mm). These real-world comparisons make it easier to judge whether the tablet will fit in a bag pocket, drawer, or laptop sleeve without needing a ruler.

12.9-Inch vs 11-Inch iPad Pro

Compared to the 11-inch iPad Pro, which measures 249.7mm x 177.5mm x 5.9mm and weighs around 466g in the same generation, the 12.9-inch model is significantly larger in both footprint and weight, but offers more screen real estate for productivity-focused work.

Whether you’re checking these dimensions to compare against a current-generation iPad, researching a secondhand purchase, or simply trying to visualize the tablet’s actual size, the numbers above cover everything needed to understand how big the iPad Pro 12.9-inch really is.
