Understanding European & North American Hardwood Grading Systems
Choosing the right hardwood flooring isn't only about colour, plank width, or finish. One of the most important—but often overlooked—factors is hardwood grading.
Hardwood grades describe the natural appearance of each plank, including knots, grain patterns, colour variation, mineral streaks, and other characteristics that make real wood unique. They do not indicate the strength or durability of the flooring. Whether you choose a clean, contemporary look or a floor full of natural character, all grades can offer excellent performance when manufactured to the same quality standards.
Many Canadian homeowners encounter two grading systems when shopping for premium engineered hardwood:
-
European grading: AB, ABC, ABCD (and occasionally CD)
-
North American descriptions: Select Better, Select, Character, Rustic
Understanding both systems makes it easier to compare products and choose a floor you'll love for years to come.

Although every manufacturer uses its own grading rules, the following comparison provides a helpful reference.
| European Grade | Rough North American Equivalent | Appearance |

| AB | Select Better | Clean, consistent colour with very few natural markings |
| ABC | Select / Character | Balanced mix of clean boards and natural wood character |

Frequently Asked Questions
Does a higher grade mean better quality?
No. Hardwood grades describe the appearance of the wood—not its durability or structural quality. Flooring manufactured to the same specifications will perform similarly regardless of grade.
Which hardwood grade is the most popular?
ABC Grade is one of the most popular choices because it offers a beautiful balance between clean boards and natural character.
Is AB Grade worth the extra cost?
If you prefer a consistent, modern look with minimal knots and colour variation, AB Grade is an excellent investment. It's especially popular in luxury and Scandinavian-inspired homes.
Why do rustic grades cost less?
Rustic grades include more natural variation, knots, and colour differences. Since more of the log can be used during manufacturing, these grades are often more cost-effective while still offering outstanding durability.
