When it comes to Ipe decking, there is no one-size-fits-all answer for the best spacing between boards. The amount of space you leave between your deck boards will ultimately depend on a few factors, including the width of your boards, the climate in your area, and your personal preference.
If you live in an area with a hot climate, you may want to leave more space between your Ipe deck boards so that they have room to expand without bowing or warping. On the other hand, if you live in a colder climate where your deck may be subject to freezing temperatures, you can get away with spacing your Ipe deck boards closer together since they are less likely to expand and contract.
Ultimately, the best way to determine the ideal spacing for Ipe decking in your home is to experiment and see what looks best to you. Once you have installed your decking, take a step back and assess how it looks. If it seems too crowded or spaced too far apart, simply adjust accordingly until you find the perfect balance for your outdoor space!
