How far apart should deck supports be?
Starting with your perimeter, mark the location of each deck post to locate the fitting position. In general, posts should be spaced no more than 8 feet apart.

How far should a tread overhang the riser?
Stairs must have an overhang between 3/4″ to 1-1/4” to increase the depth of the step, making it better for descent while maintaining a clear 10-inch going for the ascent. Treads that are 11-inches deep or greater do not require an overhang.
