### What does isodiametric mean?

Isodiametric describes having the same diameters or axes.

When two objects have the same diameter, they are isodiametric—that is, they have the same circular width. Two isodiametric objects may look alike, or they may look different and be different shapes. For example, two ovals could be isodiametric at their horizontal diameter but have completely different vertical diameters.

Isodiametric is especially used in geometry and any field that involves geometric design, such as architecture, engineering, or design.

In botany, isodiametric is used to describe a plant’s parenchyma cells, most of which are unspecialized. This is why they are isodiametric, or of similar size and shape.

In geology and crystallography, isodiametric describes crystals with two or three equal horizontal axes and an additional, unequal axis at right angles.

Example: The two celestial bodies are isodiametric, leading us to believe they may be similar in other ways as well.

### Where does isodiametric come from?

The first records of the term isodiametric come from around the 1880s. It combines the combining form iso-, meaning “equal,” and the term diametric, meaning “related to a straight line through the center of a circle or sphere.” Isodiametric means “of equal diameter.”
