Traditional measuring tapes are commonly available in 3, 5 or 8-metre long versions, with the size and bulk of the measuring tapes increasing as the measurable length increases. The Infinite Ruler counters these restrictions with its ability to measure any length infinitely, with a body that is one-fifth the size of traditional measuring tape rolls. The Infinite Ruler comprises a compact measuring ring that also serves as a good grip, and a digital interface for reading the measurements. With this ruler, users can measure any object with a length, and all kinds of wires, cloth and other objects. The grip design of this measuring tool is inspired by one of the most natural and intuitive action of pulling ropes. The digital interface also stores the measurement data.
