For example, a standard U.S. 25-cent coin has a diameter of approximately 0.955 inches, so you can use that to estimate the length of an inch. Other items with known dimensions, such as credit cards or some smartphone models, can also be used as reference points.

Using your hand: For most people, the distance from the tip of the thumb to the first knuckle is about one inch. You can use this distance for a rough estimate by aligning the tip of your thumb with the starting point and counting the number of thumb lengths.
