Distance Calculator
Calculate distance and midpoint between two points in 2D or 3D space.
What is the Distance Calculator & How does it work?
The Distance Calculator determines the straight-line distance between two points in either a 2-dimensional or 3-dimensional coordinate system. This is useful in various fields such as geometry, physics, and engineering.For two points A(x1, y1) and B(x2, y2) in 2D space, the distance formula is derived from the Pythagorean theorem: (d = sqrt{(x2 – x1)^2 + (y2 – y1)^2}). In 3D space, with points A(x1, y1, z1) and B(x2, y2, z2), the formula extends to include the z-axis: (d = sqrt{(x2 – x1)^2 + (y2 – y1)^2 + (z2 – z1)^2}).
(d = sqrt{(x2 – x1)^2 + (y2 – y1)^2 + (z2 – z1)^2})
d = distance, x, y, z = coordinates of points A and B

Frequently Asked Questions
How do I calculate distance between two points in 2D?
Use the formula d = sqrt((x2-x1)^2 + (y2-y1)^2).
What is the distance formula for 3D space?
The formula is d = sqrt((x2-x1)^2 + (y2-y1)^2 + (z2-z1)^2).
Can this calculator handle negative coordinates?
Yes, the calculator can handle both positive and negative coordinates.
Is there a limit to how large the numbers can be?
The calculator supports a wide range of numbers, but very large or small values might result in precision loss.
Can I use this to calculate distances on a map?
This tool calculates straight-line distances, not following the curvature of the Earth. For maps, consider using geographic distance calculators.
What if I only have one point’s coordinates?
You need at least two points to calculate a distance.
Is this calculator accurate for all types of distances?
It is most accurate for Euclidean distances in Cartesian coordinate systems.
