# Ellipse vs. Oval: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 29, 2024
An ellipse is a geometric shape with two focal points where the sum of distances to these foci is constant, while an oval is a broader term for any egg-like or elongated circular shape.

## Key Differences

An ellipse is a specific type of oval defined mathematically, with two focal points. In an ellipse, the sum of the distances from any point on the curve to the two focal points is constant. An oval, on the other hand, is a more general term for any elongated round shape, often used in everyday language to describe shapes similar to an ellipse but without specific mathematical properties.

An ellipse always has two axes of symmetry - the major and minor axes. Ovals may or may not have such symmetry and do not necessarily have specific focal points.

Ellipses have specific applications in astronomy, physics, and engineering due to their mathematical properties. Ovals are more commonly referenced in general descriptions, such as in design, art, and daily objects like mirrors or tracks.

Drawing an ellipse can involve mathematical techniques like using string and pins (foci), or using an ellipsograph. An oval can be drawn more freely, without needing to adhere to strict geometric rules.

#### Ellipse

An oval or oblong figure, bounded by a regular curve, which corresponds to an oblique projection of a circle, or an oblique section of a cone through its opposite sides. The greatest diameter of the ellipse is the major axis, and the least diameter is the minor axis. See Conic section, under Conic, and cf. Focus.
