Square Edge:

The edges of all boards meet squarely creating a uniform, smooth surface that blends the floor together from board to board. The overall look of this floor gives a contemporary flair and formal feeling to the room.

 
Eased Edge:

Each board is just slightly beveled. Some manufacturers add an eased edge to both the length of the planks as well as the end joints. Eased edges are used to help hide minor irregularities, such as uneven plank heights. Eased edge is also called microbeveled edge.

 
Beveled Edge:

These products have a very distinctive groove in them. Beveled edge planks lend themselves to an informal and country decor. With the urethane finishes applied at the factory today, the beveled edges are sealed completely, making dirt and grit easy to be swept or vacuumed out of the grooves.
