We recommend and support the use of BookBook with Apple MacBooks. We can’t comment on the fit of other laptops however, if you measure the outside dimensions of your laptop and compare them with the outside dimensions of the various MacBooks, you can determine if it will fit or not.
MacBook Pro (13-inch, M1 & USB-C) 11.97" x 8.36" x 0.59" (304.1 mm x 212.4 mm x 15.3 mm)
MacBook Pro (14-inch) 12.31" x 8.71" x 0.61" (312.6 mm x 221.2 mm x 15.5 mm)
MacBook Pro (16-inch, 2019-2020) 14.09" x 9.68" x 0.64" (357.9 mm x 245.9 mm x 16.2 mm )
MacBook Pro (16-inch, M1 late-2021) 14.01" x 9.77" x 0.66" (355.7 mm x 248.1 mm x 16.8 mm)
Please note that BookBook is a hardcover case so it is very unforgiving of excess size. In other words, if your laptop is bigger than the MacBook in any of the three dimensions, it won't fit. There's absolutely no 'give' to this case. And there are no internal restraints in the BookBook so if your laptop is significantly smaller, it may shift around inside the case.
