# Distance From Point to Plane Calculator

Enter the equation of a plane and the coordinates of a point to calculate the distance from the point to the plane.

## Distance from point to plane formula

The following equation can be used to calculate the distance between a plane and point.

d = |A·X + B·Y + C·Z + D/ √A2 + B2 + C2

• Where D is the distance
• A, B, C and D are constants of the plane equation
• X, Y, and Z are the coordinate points of the point

How to calculate the distance from a point to a plane

1. First, determine the equation of the plane.

A 3-dimensional plane can be represented using an equation in the form AX + BY + CZ + D.

2. Next, gather the constants from the equation in stead 1.

Separate A, B, and C in the equation determined in step 1.

3. Next, determine the coordinates of the point

Measure or calculate the coordinates of the point x,y, and z.

4. Calculate the distance

Calculate the distance from the point to plane using the equation above and information from steps 1-3.

## FAQ

How can you calculate a distance from a point to a plane when the plane is everywhere?

Great question. The answer to this is that you can only calculate the average distance to the plane which will be a point directly perpendicular to the point and plane.
