Find the center of a coordinate segment
Midpoint coordinate
Calculate the exact ordered pair halfway between two endpoints.
Coordinate averages
See the x average and y average separately so the midpoint formula is transparent.
Segment checks
Use horizontal and vertical change to compare the midpoint with slope or distance work.
Midpoint formula used on this page
The midpoint formula averages the x coordinates and y coordinates independently to find the halfway point.
Working formulas
Midpoint
M = ((x1 + x2) / 2, (y1 + y2) / 2)
Average the two x values for the midpoint x coordinate, then average the two y values.
Midpoint x-coordinate
Mx = (x1 + x2) / 2
This gives the horizontal center between the endpoints.
Midpoint y-coordinate
My = (y1 + y2) / 2
This gives the vertical center between the endpoints.
Symbols
- x1, y1 - first endpoint
- The coordinate values for the first point on the segment.
- x2, y2 - second endpoint
- The coordinate values for the second point on the segment.
- Mx - midpoint x
- The average of the two x coordinates.
- My - midpoint y
- The average of the two y coordinates.
Midpoint output with the coordinate averages visible
Fast coordinate center

Why midpoint is a foundation coordinate formula
The midpoint formula is simple, but it supports many coordinate geometry workflows. Students use it to find the center of a segment, verify symmetry, build bisectors, check graphing work, and prepare for distance or slope problems. Toolarithm's Midpoint Calculator is designed to make the arithmetic transparent by showing the final ordered pair and the two separate averages. That makes it easier to catch mistakes such as averaging x with y or forgetting to divide by two.
Midpoint connects naturally to the distance formula and slope because all three use the same coordinate pair inputs in different ways. A student may start with the midpoint, then need to measure the segment or describe the line through the endpoints. Keeping those related calculators close helps users move through a complete coordinate geometry lesson without retyping the same coordinates into unrelated tools.
