The Best of Both Worlds
Exclusively at AdvantageLumber.com!
When you’re designing a project that demands both performance and value, choosing the right board size can make all the difference. That’s why AdvantageLumber.com developed the 1×6 +Plus® hardwood profile: a dimension that perfectly bridges the gap between traditional 1×6 and thicker 5/4×6.
Similar Strength to 5/4×6
The 1×6 +Plus® board measures just shy of 7/8″ thick by 5 ½″ wide (21mm x 140mm). That small increase in thickness delivers a big advantage: it’s nearly as strong as a full 5/4×6 board, with the rigidity and stability to span joists spaced 24″ on center. In real-world terms, it provides greater strength, stiffness, and longevity than standard 1×6 decking, while staying light enough to handle and install easily.
Similar Cost to 1×6
Even better, this upgrade in performance doesn’t come with a steep price tag. 1×6 +Plus® sits comfortably between standard and premium sizes in cost, offering savings of around 20% over 5/4×6! That means you can achieve nearly the same structural performance as a 5/4×6 while saving a meaningful amount on every board. Over an entire deck, those savings quickly add up without sacrificing quality or durability.
Any Species for Any Project
Like all of our premium hardwood products, the 1×6 +Plus® is available in four of our most sought-after species, each offering unique grain patterns, rich tones, and natural resistance to rot, insects, and weathering:
Versatility is another defining strength of this size, performing equally well across a range of applications:
1×6 +Plus® gives you a smarter way to build: stronger than 1×6, more economical than 5/4×6, and adaptable to virtually any application. Whether you’re crafting a luxury deck, a modern rainscreen façade, or a distinctive hardwood ceiling, this size delivers a perfect balance of strength, value, and beauty.

Frequently Asked Questions
What are the actual finished dimensions of 1×6 +Plus® boards?
The boards are milled to a finished size of 53/64″ thick by 5 ½″ wide (21 mm × 140 mm), just shy of 7/8″.
Q2: How does 1×6 +Plus® compare structurally to 5/4×6 boards?
The extra thickness over a standard 1×6 gives the +Plus® board nearly the same strength and rigidity as a 5/4×6 board, and it is engineered to span joists spaced 24″ on-center.
Isn’t a thicker board automatically much more expensive?
Not in this case. 1×6 +Plus® delivers almost the performance of a thicker (and more expensive) board, yet the cost is kept close to standard 1×6 pricing.
Can I use 1×6 +Plus® only for decks, or is it suitable for other applications?
You can absolutely use it for a wide range of applications beyond decking—its dimension and strength make it suitable for decking, siding/cladding, ceiling/soffit, fencing, and more. Its versatility allows one board size to serve multiple uses in a project.
