Oak Flooring Grades Explained

The grade of an oak floor describes how it looks, not how long it lasts. It sets how many knots, how much colour variation and how much sapwood you will see. Here is what each grade means.

01

The grades

Grading terms vary a little between mills, but these are the grades you will see across our range.

Cleanest

Prime grade

An even, calm face with very few small knots and little colour variation. The most refined look, suited to contemporary rooms and pale finishes where knots would stand out. See our Prime Grade Collection.

Balanced

Select grade

Mostly clean boards with occasional small knots and slight variation. Often written as AB grade. A good middle ground for most homes.

Natural

Classic grade

Regular knots, some larger, and natural colour variation between boards. Our most common grade; it reads as a real oak floor without looking rustic.

Characterful

Rustic grade

Larger knots, filled cracks and strong colour variation. Hides everyday wear well, which makes it practical for family homes.

Aged

Antique grade

Rustic-grade oak that has also been distressed, brushed and hand-finished to look decades old. See our distressed oak floors.

Durability

The same across grades

Grade is about appearance. Every grade has the same oak layer, the same core and the same wear resistance.

02

Choosing a grade

Start with the room and the finish, then the grade follows.

Prime grade suits minimal and contemporary interiors, very pale or invisible finishes, and herringbone where a busy grain would compete with the pattern. Classic grade is the safest choice for most homes; it looks natural and forgiving. Rustic and antique grades suit period houses, kitchens and family rooms, and anywhere you want the floor to hide marks.

Remember that a sample shows only a small piece. Grades are defined across a whole batch, so a prime-grade floor can still have the occasional small knot, and a rustic floor will have quiet boards as well as busy ones. Wood is a natural product: no two boards are the same.

Oak Grades,
Answered

The questions we are asked most often.

Ask Us Anything →
What is the best grade of oak flooring?
There is no single best grade, because grade describes appearance rather than quality. Prime grade gives the cleanest look; classic and rustic grades show more natural character and hide wear better.
What does prime grade oak mean?
Prime grade oak has an even face with very few, small knots and little colour variation between boards. It is the most uniform grade.
Is rustic grade oak lower quality?
No. Rustic grade has the same oak layer, core and durability as prime. It simply shows more knots, cracks and colour variation, which many people prefer.
What does AB grade mean on oak flooring?
AB grade, often called select grade, is mostly clean oak with occasional small knots and slight colour variation. It sits between prime and classic grades.
