So How Do I Space My Boards?!! What is the solution you ask? How to stop the madness? You can't stop it. Wood moves, get over it. Embrace it and plan the gap between that decking accordingly. In the above scenario where I installed the deck in the summer, I could install it with very little gap so that in 

If your decking boards are wet green (not dried out or seasoned), I'd skip the spacing process altogether because as the boards dry they'll create their own space. Most builders drop a “sixteen penny” nail (16d) between pairs of boards before attaching them. You also can use a strip of 1 4-inch plywood 

With the basic deck support bearer frame complete, you can begin to lay deck boards. The different deck board layouts shown in Fig. 3 from chevron to diagonal, are created using 140mm wide boards and 80 x 80mm bearers. Plan your layout before assembling your bearers, as the pattern will affect the spacing and number 

Common board widths range from 70mm to 140mm. Narrower boards allow for better drainage and have less expansion and contraction with moisture changes so are less prone to cupping. Timber decking boards are normally laid on joists at 450crs. For this spacing a thickness of 19mm is required for hardwood and

If the boards are wet when you install them, you can probably butt them close together without any gap. They should shrink as they dry out and produce adequate gaps between the boards.
