Abstract

A device (100) includes a sensor (101) to determine a capacitance between a first metal piece (209, 309, 409, 509, 609, 709, 809, 909) coupled to a paper tray (213, 413, 513, 913) of a printing device (206, 306) and a second metal piece (207, 307, 407, 507, 607, 707, 807, 907) coupled to a paper width adjuster (212) of the printing device (206, 306). The device (100) also includes a controlled (102) coupled to the sensor (101) comprising a processor (103) in communication with a memory resource (104) including executable instructions to determine a size of paper in the paper tray (213, 413, 513, 913) based on the determined capacitance.
