An adjustable measuring and marking device is provided. The device has a lower portion with a bottom end and an upper end and an upper portion with a bottom end and an upper end. The upper portion telescopically interconnects with the lower portion. Measurement intervals, such as inches, are marked along the upper and lower sections so that one can use the device as a measuring apparatus. Measurements can be read at the upper end of the bottom portion, off the top portion, in inches, as well as in feet and inches. A friction fit exists between the upper and lower sections so that a measurement obtained by extending the upper section from the lower section so that the entire device is positioned between two points, can easily be transferred to another location, as the relative position of the upper and lower sections are maintained by the friction fit. Overextending the upper portion out of the lower portion is prevented by a locking pin device. A plurality of markers can be attached to the device, at desired locations therealong, for marking desired locations on a surface. Such markings are accomplished by placing the device at a desired location, and twisting one's wrist to move the plurality of marking devices against a surface to place marks thereon.
