Which caliper jaws are used to measure inside diameters?

Measuring inside diameters is done with the inward-projecting jaws of a caliper. These inside jaws extend into a hole or bore and contact the inner surfaces on opposite sides. When you slide them together until they just touch, the reading across the scale gives the inside diameter. The larger, outside jaws measure external dimensions, the depth rod measures depth, and the main beam is the frame that carries the scale. So the inward, or inside, jaws are the ones used for inside diameters.
