Staggering the joints in strip wood flooring is done to avoid long, continuous joints that can weaken the floor and look repetitive. The joints in each row should be offset so they don’t line up with joints in the row before, providing better stability and a more natural appearance. The minimum distance you should maintain is six inches. This offset helps distribute stresses, reduces the chance of a visible repetitive pattern, and accommodates wood movement.

When installing, position each new row so its butt joints are at least six inches away from any joint in the preceding row. If a board would create a smaller offset, trim the board or adjust the layout to keep that six-inch minimum.
