## Size: will it fit your bag?

Closed, it measures **14.25 × 9.92 in** (36.2 × 25.2 cm) and is 0.62–0.82 in thick. A sleeve or laptop compartment needs inner dimensions at least that large; bag makers size compartments by screen class, and chassis in one class differ, so check the numbers, not the label. We list 12 laptops in the 16-inch class: 13.88–14.35 in wide, 9.35–10.86 in deep and 3.58–5.84 lb. By starting weight the ThinkPad P16 Gen 3 is the 10th lightest of 12.
