The Screen Plane Cannot Carry the Pack
A tablet puts a large glass surface inside a package that may only be a few inches deep. That geometry changes the protection problem. The box cannot rely on the screen face to absorb lid pressure, hold accessories in place or compensate for an insert that sits too high.
The tablet should rest on controlled support points around the chassis while the screen remains clear of hard internal components. The cavity needs enough retention to stop lateral movement without clamping the device against its display, camera area, buttons or charging port.
A box can look perfectly fitted from above and still be wrong vertically. If an insert platform is too high, closing the lid can transfer pressure toward the face of the device. If the cavity is too deep, the tablet can lift, drop back into the tray and move during handling.
That distinction is central to electronics and gadget packaging, where device geometry should decide the inside structure before decoration.
Measure the actual tablet in its packed condition. Include protective films, temporary sleeves or anything else that remains on the product when it enters the box. Rear camera projections and uneven back profiles also matter because they can change how the tablet rests even when the published length, width and thickness appear straightforward.
There is no universal clearance number for every tablet. The correct cavity depends on device geometry, insert material, retention method and how easily the tablet needs to be removed.
