Final answer:
In Excel, the height of rows is measured in points, a typographic measure that remains consistent across devices.
Step-by-step explanation:
In Excel, the height of the rows is measured in points. A point is a unit of measure used in typography and is equivalent to 1/72 of an inch. Excel uses points to measure the height of rows, which can be adjusted to accommodate the content within the cells. The measurement of row height in points ensures consistent sizing across different devices and printers, as opposed to pixels which can vary depending on a device's screen resolution.
