Ellipse vs. Oval: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || 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.
The term 'ellipse' is typically used in more technical or mathematical contexts, while 'oval' is used in everyday language for a variety of elongated round shapes.

Ellipse
A geometric figure with constant sum of distances to two foci.
In geometry, an ellipse can be constructed using string and pins.
Oval
An elongated circular shape resembling an egg.

Ellipse
A conic section whose plane is not parallel to the axis, base, or generatrix of the intersected cone.
Oval
Resembling an egg in shape.

Ellipse
(geometry) A closed curve, the locus of a point such that the sum of the distances from that point to two other fixed points (called the foci of the ellipse) is constant; equivalently, the conic section that is the intersection of a cone with a plane that does not intersect the base of the cone.

Ellipse
(grammar) To remove from a phrase a word which is grammatically needed, but which is clearly understood without having to be stated.

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.

FAQs
What is an ellipse?
