How to measure for stair stringers?

1. Determine the total height of the stairs. Extend the level to the top of the deck or porch (or access point if you're building)
2. Set the height of each step. Most steps have a height or "rise" of about 18 to 19 cm. Higher levels can be difficult to climb,
3. Divide the height of the ladder by the desired height. For example, if your patio is 140cm (56 inches) off the ground and you choose a height of 7
4. Divide the height again by the number of steps. Repeat the same formula, but this time insert the numbers backwards. Let's continue with the example
