Laptop keyboards, while they use the standard QWERTY layout for their
alphanumeric keys, have many creative ways of arranging the remaining keys.
This page lets you compare keyboard layouts and sizes.
Systems are organized by decreasing
alphanumeric key size. Click on each keyboard image to get a larger view;
these views also have rough measurements of the keyboard and mouse area. Key
pitch and stroke measurements are taken from the
manufacturers' literature, when available; they usually
apply only to the alphanumeric keys.
