Distance Between Two Points Calculator with Midpoint and Slope

Calculate the distance between two points, find their midpoint, and determine the slope of the line connecting them.

Practical Example:

GPS Navigation: If you're at position (3, 4) and need to reach (7, 10):

Distance = 7.21 units (could be miles or kilometers)
Midpoint (5, 7) = halfway point for a rest stop
Slope = 1.5 = for every 1 unit east, you travel 1.5 units north

Try these coordinates above to see the calculations!

How It Works

Use this distance between two points calculator for fast, clear results. It computes the straight line distance, the midpoint, and the slope. Enter the four coordinates, then run a single calculation. The math follows standard coordinate geometry. Distance shows four decimal places for clarity. Midpoint shows two decimal places. Slope shows four decimal places, with clear labels for special lines.

Why You'll Love It

You get three answers in one place. Results appear clean and easy to read. Click once or press Enter to run it again. It fits study, work, and quick checks.

Check spacing on a drawing or site plan.
Verify homework steps in geometry or algebra.
Estimate straight line trips across a map grid.
Pick a halfway meeting spot with the midpoint.
Find a line’s slope for charts or data work.

A Real-Life Example

Try points at (3, 4) and (7, 10). Here is what you will see:

Distance: 7.2111 units
Midpoint: (5.00, 7.00)
Slope: 1.5000

This slope means one step east moves one point five steps north. Simple.

Step-by-Step Guide

1. Add Your Coordinates

Enter values for both points before you calculate. Here is what each field means:

X1 is the x coordinate of point one.
Y1 is the y coordinate of point one.
X2 is the x coordinate of point two.
Y2 is the y coordinate of point two.
Use whole numbers or decimals as needed.
Use positive or negative values for any axis.
Pick a unit like meters, miles, or pixels.
Keep the same unit for all four inputs.

2. Calculate at the Click of a Button

Click the Calculate button or press Enter in any field. Fill all four fields with numbers first. If a field is empty the tool shows "Please enter valid numbers for all coordinates".

3. Get Your Result

Read the three outputs and apply them right away.

Distance shows the straight line length in your unit.
Midpoint shows the exact halfway point between the inputs.
Slope shows rise over run for the line through both points.
Vertical lines show "Undefined (vertical line)".
Horizontal lines show "0 (horizontal line)".
Rounding keeps values neat for quick work and sharing.

Got Questions?

Here are useful notes and limits to keep in mind.

The calculator uses a flat two dimensional plane.
It ignores roads and terrain for distance.
It ignores Earth curvature and map projection.
Units depend on your inputs and stay consistent.
Large values and small values compute the same way.
Repeating decimals may round in the display.
Press Enter to run new numbers without moving your mouse.

Your Next Steps

Try the distance between two points calculator with your own data. Test a few pairs and compare results. Use the midpoint for fair splits and meetups. Use the slope for lines, charts, and trend checks. Save this page, and keep it ready for your next quick calc.
