Square countertop edges are the perfect fit for a very modern, contemporary design. You may even choose a square edge if you want your countertops to look sleek and simple.
Beveled edges are sleek and angled. They are popular with more contemporary designed kitchens. Beveled edges are frequently used with granite countertops because they have an elegant feel to them.
The quarter round edge is a very common stone edge profile. This is because it is simple and rounded just enough to remove the sharp edges off of the stone. It is typically less expensive because it requires less equipment to manufacture. For many types of stone, this may be the default edge.
Half Bullnose edges are another popular choice. They have a much softer and curvier look to them. The top edge is rounded but the bottom is still around 90 degrees. It is safer than eased and bevel edges so ideal for homes with children.
Waterfall countertops are very popular right now. A waterfall edge means the side drops vertically to the floor rather than stopping at the very edge of the counter or island. It creates a continuous flow that connects the floor to the cabinets. It has a deep impact on the room. This is a sleek minimal look perfect for homes with a modern décor style.
