Rectangle Diagonal Calculator
Need to find the diagonal of a rectangle but don’t want to dust off your old geometry textbook? We’ve got you covered!
Whether you're rearranging furniture, designing a logo, or just curious about the math behind rectangles, our Rectangle Diagonal Calculator makes it a breeze. Simply plug in the width and height, and voilà—your diagonal length is ready in seconds. No complex formulas, no headaches. Just quick, accurate results that save you time and effort. Because who doesn’t love a little math magic?
Enter the width and height of the rectangle to calculate its diagonal.
Diagonal Length: - units
How It Works
The tool uses the Pythagorean theorem—a classic geometry formula—to calculate the diagonal of a rectangle. Here’s the simple breakdown:
Diagonal = √(Width² + Height²)
So, if your rectangle has a width of 3 units and a height of 4 units, the diagonal would be √(3² + 4²) = √(9 + 16) = √25 = 5 units. Easy, right?
Example Calculations
| Width (units) | Height (units) | Diagonal (units) |
|---|---|---|
| 1 | 1 | 1.41 |
| 2 | 3 | 3.61 |
| 4 | 5 | 6.40 |
| 6 | 8 | 10.00 |
| 10 | 10 | 14.14 |
