A pipe size measuring tool for identifying the pipe configuration, i.e., outer diameter and inner diameter, having a plurality of gauges, each gauge having an open mouth therein. The sizes of the open mouth in each gauge are different from each other. The gauges are mounted together with each gauge having a front end, a body portion and a rear end. The gauges are pivotally mounted together adjacent their rear ends so that they are moveable from a folded compact position to an open position. The front ends are wider than the rear ends and the gauges are thin light-weight. The gauges are of different sizes with the larger open mouths located in the larger gauges with indicia on the gauge which identifies the pipe measured.

1. A method for identifying the size of pipe installed in the ground by a hand-held pipe size gauge, having a front end portion with pointed tips, comprising the steps of:a) locating the pipe in the ground, b) pushing the pointed tips of the front end portion of said gauge into the ground overlying the pipe, generally 90 degrees perpendicular to the pipe, c) providing an open and generally semicircular inwardly curved mouth of said gauge to determine a snug fit of said open mouth to the diameter of said pipe, d) repeating step b with gauges having different size front-end portions and mouths, until said snug fit between the mouth of the gauge and the curvature of the pipe is obtained, and reading the size of the pipe from the gauge.
