keyboard property
How tall the software keyboard is on this device, in logical pixels — 0 for a device that has none, which is every desktop size.
Measured, not computed, like landscape and for the same reason: there is no formula. A 375-wide phone with a home button gets 260 and a 375-wide phone with a notch gets a different number entirely, because the number includes whatever the platform puts under the keys.
The height with the predictive bar, which is what a phone shows out of the box.
