Ellipse Calculator
An ellipse is a smooth, oval-shaped figure that looks like a stretched circle. You can see ellipses in running tracks, garden designs, swimming pools, and even in astronomy. Calculating the area of an ellipse by hand can be confusing if you do not remember the formula. The Ellipse Area Calculator makes this task simple, fast, and accurate.
With just two measurements, you can instantly find the area of any ellipse. This tool is helpful for students, teachers, designers, engineers, and anyone who works with oval shapes.
What Is an Ellipse?
An ellipse is a closed curve where the distance from two fixed points (called foci) stays the same. In simple words, it is an oval shape.
An ellipse has two important parts:
-
Major axis – the longest diameter
-
Minor axis – the shortest diameter
Half of the major axis is called the semi-major axis (a), and half of the minor axis is called the semi-minor axis (b). These two values are used to calculate the area.
Why Calculating Ellipse Area Is Important
Knowing the area of an ellipse is useful in many real-life situations.
Some common uses include:
-
Designing running tracks and stadiums
-
Planning oval swimming pools
-
Landscaping and garden layouts
-
Architecture and construction projects
-
School and college geometry problems
Accurate area calculation helps in proper planning and material estimation.
How the Ellipse Area Calculator Works
The calculator uses a simple formula based on the two radii of the ellipse.
You can enter:
-
The semi-major axis (a)
-
The semi-minor axis (b)
If you only know the full diameters, the calculator divides them by 2 automatically to get the correct values.
Once the numbers are entered, the calculator shows the ellipse area instantly.
Ellipse Area Formula Explained
The standard formula for the area of an ellipse is:
Where:
-
a = semi-major axis
-
b = semi-minor axis
-
π (pi) ≈ 3.1416
Example
If an ellipse has:
-
a = 6 meters
-
b = 4 meters
Then:
The calculator does this calculation for you automatically.
Using Diameter Instead of Radius
Sometimes, you may know the full length of the major and minor axes.
In that case:
The calculator converts these values and finds the correct area.
