# Height or Distance Calculation with a ruler (Biltmore stick)

**Calculation of the height or distance of an object with the aid of a ruler.** One value, distance or height, must be known or estimated. At length of the stretched arm from eyes to ruler, an average value (in cm) is set. For a better estimation, you should take your measure.

**Biltmore stick:** stretch one arm and hold up a ruler. On this, you can read the apparent height of the distant object.

Formula: d = b * c / a
