Stairway Construction Fundamentals

This video tutorial guides viewers through the process of measuring and calculating the dimensions of a stairway. It begins with determining the vertical rise and then uses a formula involving the number seven to calculate individual riser heights. The tutorial explores different riser height options and provides guidance on maintaining standard dimensions. It also explains how to calculate the stairway's horizontal length using tread depth. The video concludes with a mention of additional resources available for further learning.

What is the first step in determining the dimensions of a stairway?

• Measuring the vertical distance between floors

• Calculating the number of treads

• Measuring the width of the stairway

• Determining the color of the stairs

Why is the number seven used in calculating the riser height?

• It is a magic number that works well in the formula

• It simplifies the calculation process

• It is the average height of a step

• It is a standard number for all calculations

What is the result of dividing the total stair rise by seven in the example?

• Twelve point eight two

• Seven point four five

• Eight point one five

• Six point nine

What is the recommended range for individual riser heights?

• Between five and six inches

• Between six and seven and three quarter inches

• Between seven and eight inches

• Between eight and nine inches

How many risers are calculated in the example using the number twelve?

• Thirteen

• Twelve

• Ten

• Eleven

What is the maximum height recommended for an individual riser?

• Six inches

• Seven inches

• Seven and three quarter inches

• Eight inches

What is the depth of each stair tread used in the example?

• Eight inches

• Nine inches

• Ten inches

• Eleven inches

How is the length of the stairway calculated?

• By dividing the total rise by the number of treads

• By multiplying the number of treads by the depth of each tread

• By subtracting the riser height from the total rise

• By adding the width of the stairway

What is the total length of the stairway base in the example?

• One hundred inches

• One hundred and ten inches

• One hundred and thirty inches

• One hundred and twenty inches
