Slope Calculator for 6:12 Roof Pitch
Common residential roof pitch where the roof rises 6 inches for every 12 inches of horizontal run.
Computes the slope of a line using the rise over run formula. Enter your Rise (vertical change), Run (horizontal change) to get an instant slope. Formula: rise / run.

How It Works
How It Works
This calculator finds the slope of a line using the basic rise over run formula. Rise is the vertical change between two points, and run is the horizontal change between those same points.
To calculate the slope, the calculator simply divides the rise by the run. The result shows how steep the line is as a single decimal number.
- Slope is calculated using: rise ÷ run
- Rise is the vertical change
- Run is the horizontal change
- The result is shown as a decimal (unitless ratio)
Understanding the Results
The slope tells you how steep a line is and in which direction it moves. A larger number means a steeper line.
If the result is positive, the line goes upward from left to right. If it is negative, the line goes downward from left to right.
- Positive slope means the line rises
- Negative slope means the line falls
- A slope of 0 means the line is flat
- The value is unitless because it is a ratio
Frequently Asked Questions
What does the Slope Calculator compute?
The Slope Calculator computes the slope of a line using the rise over run formula (rise ÷ run). Slope measures how steep a line is by comparing the vertical change to the horizontal change between two points. The result is displayed as a decimal and is unitless.
When should I use the Slope Calculator?
Use this calculator when you know the vertical change (rise) and horizontal change (run) between two points and want to determine the slope. It is useful in algebra, geometry, construction, engineering, and graph analysis. For example, if a line rises 4 units and runs 2 units, the slope is 2.
What do 'rise' and 'run' mean?
Rise refers to the vertical change between two points, while run refers to the horizontal change. For example, if you move up 6 units and to the right 3 units, the rise is 6 and the run is 3. The slope would be 6 ÷ 3 = 2.
Can the slope be negative?
Yes, the slope can be negative if the rise is negative while the run is positive, or vice versa. A negative slope indicates that the line goes downward from left to right. For example, a rise of -5 and a run of 2 results in a slope of -2.5.
What happens if the run is zero?
If the run is zero, the calculation involves division by zero, which is undefined. This represents a vertical line, and vertical lines do not have a defined slope. To calculate slope, make sure the run value is not zero.
Why is the slope unitless?
Slope is unitless because it is a ratio of two measurements with the same units. When you divide rise by run, the units cancel out. For example, meters divided by meters results in a pure number.
