The present invention relates to a portable measuring instrument, comprising: a main body including a pair of measuring holders and a pair of handles, wherein the measuring holders have respective tips which are brought closer to one another or are spaced apart from one another, the measuring holders face each other to accommodate or release an object to be measured, and the handles enable the measuring holders to be spaced apart from one another; a rotating shaft which couples the measuring holders together such that the measuring holders are rotatable; and a measuring tape which passes through the tips of the respective measuring holders such that the measuring tape is wound/unwound onto/from the main body, wherein the measuring tape is coiled along the circumference of the object to be measured when the measuring holders are brought closer to one another or are spaced apart from one another, so as to measure the size of the object to be measured. Accordingly, a worker may measure the diameter of the object to be measured in a convenient manner using one hand, and the time required for the measurement can be shortened.
