Screen size
The screen size of the device the case is designed for. This parameter directly determines the dimensions of a compatible tablet or e-reader. A device with a larger diagonal will simply not fit into the case, however, smaller sizes than those indicated in the case specifications are also not recommended — at best, the device will hang inside (which will negate many advantages), and at worst, it will not stay in the case at all .
It should be noted that this parameter is critical if you select a universal cover (see "Compatibility"). If the specifications directly indicate compatibility with the model of your tablet or reader, the screen size is for reference only, because. case by definition is optimized for the dimensions of the respective device.
