Calculating Stair Stringer Length

The video tutorial demonstrates how to scale down measurements from a piece of paper to calculate the length of a stair stringer. It provides an alternative method to using the Pythagorean theorem by breaking down measurements into smaller, manageable parts. The tutorial includes practical examples and adjustments to ensure accuracy when scaling and drawing on paper.

What is the first step in the process of calculating stair stringer length?

• Draw the measurements on the wall

• Use the Pythagorean theorem

• Grab some measurements and scale them down

• Measure the angle on the paper

What is the main topic of the video?

• Building a house

• Calculating stair stringer length

• Using the Pythagorean theorem

• Drawing architectural plans

What is the total rise in the example provided in the video?
