1.66 inches on a ruler is slightly less than 1 and 3/4 inches. On a standard ruler, you would find the 1-inch mark, then the 1.5-inch mark (which is halfway to 2 inches), and 1.66 inches would be just a bit beyond that, closer to the 1.75-inch mark. It can be estimated as just over 1 and 2/3 inches.
