A standard AA battery measures approximately 1.97 inches in length, sitting so close to the 2-inch mark that it functions as one of the most dependable everyday objects that measure 2 inches.

A standard golf tee measures exactly 2.0 inches from base to pointed tip — a dimension that is not accidental but engineered to position the ball at the optimal height for the majority of drives on a regulation course.

Hold a single matchstick up and you are looking at a near-perfect 2 inches of length that has stood unchanged for generations.

Medium Lime

A medium lime from the produce aisle of any American grocery store measures approximately 1.9 to 2.1 inches in diameter, making it one of the most naturally occurring things that are 2 inches long found in everyday kitchens.

What surprised me is how often that tiny skill pays off.
