**What is a 3/12 Pitch Calculator**?

A 3/12 Pitch Calculator is a tool used to calculate the pitch or slope of a roof represented as a ratio.

It determines how many inches the roof rises for every 12 inches of horizontal run.

**Why is a 3/12 Pitch Calculator Used**?

This calculator is used in construction and roofing to express the slope or pitch of a roof in a standardized format.

It’s essential for roof design and construction to ensure proper drainage and load-bearing capacity.

## 3/12 Pitch Calculator

Use this calculator to determine the pitch or slope of a roof represented as a ratio. A 3/12 pitch means the roof rises 3 inches for every 12 inches of horizontal run.

**How to Use a 3/12 Pitch Calculator:**

- Enter the rise value in inches (how much the roof rises vertically).
- Enter the run value in inches (the horizontal distance over which the roof extends).
- Click the "Calculate" button.
- The calculator will provide the pitch of the roof as a ratio, e.g., 3/12.

**Example Calculation:**

Suppose you want to calculate the pitch for a roof that rises 6 inches vertically (rise) over a horizontal distance of 24 inches (run).

After entering these values and clicking "Calculate," the calculator will determine that the pitch of the roof is 6/24, which can be simplified to 1/4.
