S4S is a lumber term describing a board that has been surfaced on how many sides?

Explanation:
S4S means surfaced on four sides: both faces and both edges have been planed smooth. This makes the board square and ready for layout and joinery, with no rough edges or uneven surfaces to reference. If a board is only surfaced on two sides, only those two faces are finished and the edges remain rough; one side leaves three unfinished surfaces, and three surfaces isn’t the standard labeling for stock. That’s why the four-sides surfaced option is the best choice.
