Step 6 · Determine the Total Run
Multiply the number of treads (from Step 5) by the desired tread depth. A common tread depth is 10 to 11 inches, but this can vary. Ensure the tread depth is consistent and meets local code requirements. For example, if you have 13 treads and a desired tread depth of 10 inches, the total run is 13 * 10 = 130 inches.
