These terms describe the edges and ends of a hardwood floor’s boards, AKA the edge profile. The edge profile for you is, basically, a matter of personal taste. Square edges are flush and butt up tight to one another for a seamless look. Bevel- and eased-edges have a slight angle on the top edge of the plank or strip. These edge profiles add a bit more drama and tend to hide minor imperfections where the boards meet. You can also feel these edge profiles as you walk on the floor barefoot. Bottom line, it’s all about your preference.
