Distance between 2 points (3D)
Welcome to our 3D Distance Calculator, a valuable tool designed to help you accurately calculate the distance between two points in threedimensional space. Whether you're working in fields like mathematics, physics, engineering, computer graphics, or simply exploring spatial relationships, this calculator simplifies the process of finding the straightline distance between any two points in 3D space.
What is the 3D Distance Calculator?
The 3D Distance Calculator is a straightforward tool that allows you to input the coordinates of two points in threedimensional space, represented by the first point (X1
, Y1
, Z1
) and the second point (X2
, Y2
, Z2
). Once these coordinates are provided, the calculator computes the straightline distance between these points, often referred to as the Euclidean distance, denoted as (d
).
How Does it Work?
The calculator uses the threedimensional extension of the Pythagorean Theorem. This theorem, traditionally applied in 2D space, is generalized to 3D by considering the additional Zaxis. The distance (d
) between the two points is determined by the following formula:
d = √(X² + Y² + Z²)
d = √((X2  X1)² + (Y2  Y1)² + (Z2  Z1)²)
This formula calculates the length of the diagonal (hypotenuse) of a cuboid formed by the differences in the X
, Y
, and Z
coordinates of the two points. Essentially, it gives you the shortest possible distance between the two points in 3D space.
Practical Applications
The ability to calculate the distance between points in 3D space has numerous practical applications across various fields:

Engineering and Architecture: In design and construction, understanding distances in 3D is crucial for creating accurate models, blueprints, and structures.
