A universal tape measure including a housing formed with a downward extending opening on a lateral side. A lower end of the opening is disposed with a pen tip opening. An inner wall of the opening is disposed with intersecting cross lines which outward extend to mark a right angle cutout. The tape measure is marked with scales such as metric system scale, British Imperial scale and/or other scales. The tape measure is further formed with a circle center hole. The universal tape measure has the functions of drafting a circle, measuring whether an article is vertical and measuring the horizontal distance between two points on different levels.
