It’s designed for anyone and everyone—from those engaging in weekend DIY projects to professionals in construction and interior design. By inputting the necessary dimensions, the calculator provides an accurate diagonal measurement, saving time and enhancing the precision of your projects.
Formula of Feet & Inch Diagonal Calculator
The underlying formulas for calculating diagonals vary based on the shape:
- Rectangle: Diagonal = √(Length^2 + Width^2)
- Square: Diagonal = √2 × Side
- Right Triangle: Hypotenuse = √(Side₁^2 + Side₂^2)
- Equilateral Triangle: Side × √3
- Parallelogram: Diagonal = √(Side₁^2 + Side₂^2 + 2 × Side₁ × Side₂ × cos(θ))
- Rhombus: Diagonal = √(4 × Side₁^2 + 4 × Side₂^2) / 2
- Trapezoid: Diagonal = √(Top Length^2 + Bottom Length^2 + (Height)^2)
- Regular Pentagon: Diagonal = φ × Side
- Regular Hexagon: Diagonal = 2 × Side
These formulas ensure that regardless of the shape you are working with, you can quickly and accurately determine the necessary diagonal lengths.
Practical Application Table for Common Measurements

| Right Triangle | 3’x4′ | 5′ |
| Equilateral Triangle | Side: 3′ | 5’2″ |
| Parallelogram | Sides: 3′ and 4′, Angle: 60° | 5’9″ |
| Rhombus | Sides: 3′ | 4’2″ |
| Trapezoid | Top: 3′, Bottom: 4′, Height: 3′ | 5’10” |
| Regular Pentagon | Side: 2′ | 3’8″ |
| Regular Hexagon | Side: 2′ | 4′ |
Example of Feet & Inch Diagonal Calculator
Imagine you’re setting up a home theater and need to know if your new TV will fit on a specific wall. By measuring the length and width of the TV (or the desired space), you can use the rectangle formula to determine the diagonal measurement, ensuring the TV fits perfectly in the designated space.
