What’s the difference among the different grades of hardwood flooring? Which is better… select grade or Number 1?
Most customers don’t realize that there are different grades of oak flooring. They just assume all oak flooring is the same. For oak flooring, there are 3 main grades: select, Number 1 common and Number 2 common. Select grade is generally considered the highest grade as it has the least color variation. It costs the more. This is followed by No 1 which has more color variation and some occasional knots, and that is followed by No 2 which has a lot more color variation and knots. Sometimes, this is called character grade or cabin grade wood.
Technically, the quality of the wood (as measured by hardness/durability) is the same across all the grades. The differences between the grades are their appearances. Some people prefer the higher color consistency that you find in select grade; others prefer more color variation that you find in Number 1 oak, and still others prefer a more rustic look and feel that it adds more character. There is no right or wrong answer here; it is preference and it’s important to understand which you prefer.

Number 2 (No 2) Common – red oak
The differences in the color among the boards are more obvious when the wood is natural (i.e. without a stain). The darker the stain, the less you notice the color difference in the boards.

When you are getting estimates from flooring contractors, it’s important that they specify what grade of wood they are using. Sometimes, the main reason that one estimate differs from another is based on the hardwood being used. And, if a contractor doesn’t specify, they are probably going to use a lower grade since it costs them less (and they may think that you won’t notice or won’t know any better.
