Because of this you should never space your stair stringers more than 16â on center.This means you will need to install a minimum of four stringers on any stairway wider than 36â. Always check the maximum span for your decking material as it applies to stair treads.Some composite materials and lower grade 5/4 wood decking may require you to reduce the stringer spacing to 10â on center.Always read the composite decking installation instructions for stair treads before building your stairs.lways check the maximum span for your decking material as it applies to stair treads.
