← 所有工具屋顶坡度
确定屋顶坡度的倾斜度、角度和百分比。
In construction, the 'pitch' of a roof describes its vertical rise relative to its horizontal run. Understanding pitch is vital because it determines which roofing materials can be used (e.g., shingles vs. metal), how fast water will drain, and the complexity of the rafter cuts. In the US, pitch is typically expressed as a ratio over 12 (like 4/12), while engineers may prefer degrees. Our Roof Pitch Calculator provides both, helping homeowners and contractors communicate clearly and ensure their roof meets local building codes for snow load and weather resistance.
工作原理
The tool uses the Rise and Run inputs to calculate the slope. It determines the Pitch-over-12 by normalizing the ratio, and uses the arctan function to find the exact Angle in degrees.
计算公式
Pitch = (Rise/Run) × 12 | Angle = arctan(Rise/Run)
计算示例
1. **Common**: 6in rise, 12in run = **6/12 pitch (26.6°)**.
