The midpoint of two points is simply the average of their coordinates — the exact point halfway along the straight line connecting them.
This calculator finds the midpoint between two points in 2D or 3D space.
How it works
Choose 2D or 3D, then enter the coordinates of both points. The calculator averages each coordinate independently to find the midpoint.
- Enter dimension.
- Enter point 1 — x.
- Enter point 1 — y.
- Enter point 1 — z (3D only).
- Enter point 2 — x.
- Enter point 2 — y.
- Enter point 2 — z (3D only).
- Click Calculate to see your results.
Examples
(0,0) to (4,6)
The midpoint between (0,0) and (4,6) is (2,3) — the average of each x and y coordinate.
Who should use it
- Checking geometry or coordinate-plane coursework.
- Finding the center point between two locations in a coordinate-based design or layout.
Industry applications
- Geometry and mathematics education
- CAD, design, and computer graphics
Advantages
- Supports both 2D and 3D coordinate systems.
- Simple, direct application of the standard midpoint formula.
Limitations
- Only finds the midpoint of a straight line segment, not points along a curve.
Common mistakes to avoid
- Averaging only some of the coordinates and forgetting others (especially z in 3D mode).
- Confusing the midpoint formula with the distance formula — they solve different problems.
Best practices
- Sanity-check your result: the midpoint's coordinates should always fall between the corresponding coordinates of the two original points.
Tips
- The midpoint formula is a special case of a more general "weighted average" point — shifting the weight toward one point instead of splitting it evenly produces any point along the segment, not just the middle.
