The sleeve fits laptops with a maximum screen diagonal of 16 inches and is compatible with Apple and Universal models. As the Lenovo ThinkPad T16 is also a 16-inch device, the sleeve should generally fit. However, the sleeve is specially designed for the MacBook Pro 16-inch, so there may be slight differences in the fit for the Lenovo ThinkPad T16. The exact internal dimensions of the sleeve are 14.13" x 9.87" x 0.9" (approx. 35.8 cm x 25 cm x 2.2 cm), which you should compare with the dimensions of your ThinkPad to be sure.
