What does equidistant mean?

If two things or places are equidistant from something, they are equally far away.

Equidistant is another way of saying equally distant, meaning at the same distance from something. This doesn’t mean they are in the same location: two different cities might be equidistant to where you live—they might be both 50 miles away from your home. Often, equidistant refers to things that are approximately but not exactly the same distance apart.

Example: The architectural plans require every single pole to be equidistant to the main pillar—they should all be exactly 27 feet away.

Where does equidistant come from?

The first records of equidistant come from the 1500s. It derives from the Late Latin aequidistāns and is a combination of equi-, meaning “equal,” and the adjective distant, meaning “far apart.”

Equidistant is used in comparisons that require at least three points or locations: the primary location and two or more points that are equally far away from it. In a very strict, technical sense, equidistant means exactly the same distance apart. In geometry, the center of a circle is known to be equidistant from any point on its circumference (its outer boundary). In fields like architecture and engineering, the term equidistant might be used in a very precise way for practical purposes, such as when constructing buildings or bridges. But in everyday conversation, when we describe locations as equidistant, we typically mean that they are roughly the same distance away from something. For example, if one grocery store is located 3.2 miles from your house, and another grocery store is located 3.5 miles from your house, you’re likely to consider the two stores equidistant. (Since they’re the same distance away, you’ll probably usually go to the one you like better, like the one with the better salad bar.)

It is important to remember that two points can be equidistant from a main point without all three being in a straight line. In the example above, one grocery store might be located west of your house, and the other might be located to the southeast. Even though all three points don’t lie within a straight line, the two stores are still considered equidistant.
