# How to Design a Sloped or Angled Member

> How to Design a Sloped or Angled Member

To calculate a sloped member in Calcs.com, you need to use [user formulas](/docs/running-calculations/adjusting-a-calculation/change-units/how-to-use-formulas-convert-units-inputs) to adjust lengths and support locations by the rise/run or degrees of the given slope. In this way, you can still enter the length of a rafter from the plan drawing and adjust it in Calcs.com using the simple formulas below.

**Using Rise/Run**

The formula for 7:12in rise over run is:

```
Member Length * SquareRoot(Rise^2+Run^2)/Run
=5ft * sqrt(7^2+12^2)/12
```

Sub in the rise required rise and member length

*Example 1:* 5ft beam with rise of 7:12 inches

**Using Degrees**

You can also adjust the length of a member based on degree slope:

```
Member Length * 1/cos(theta)
=5ft * 1/cos(30deg)
```

*Example 2:* 5ft beam with slope of 30 degrees - N.B. You need to specify either 'deg' or 'degree' units for the degrees so it calculates correctly

**Using a Slope Factor**

You can also multiply the plan length by the appropriate slope factor.
