Standard Hardwood Floor Thickness
Hardwood flooring is available in many thicknesses. However, unless you have a specific reason to purchase flooring that is thinner or thicker than the standard thicknesses, you will likely end up with a standard thickness product. The thickness varies depending on what type of hardwood you purchase.
Solid hardwood flooring that is not finished most frequently comes in 3/4-inch thicknesses. This thickness provides a significant wear layer and adds structural strength to the floor. The typical flooring plank has a wear layer that is 5/16 of an inch thick. This allows the floor to be completely refinished many more times than a floor with a thinner layer.
Engineered floors are real hardwood; however, they're built differently from solid planks. Engineered floors have a hardwood veneer on top of a plywood core. These floors look and feel like real hardwood, but the planks tend to be thinner. The standard thickness for an engineered floor is usually either 3/8 or 5/8 of an inch. This makes them a suitable option when you don't want to add too much thickness to your existing floor.
Laminate is another option for those who want a floor that looks like hardwood, but who want to spend less or are in an area of high humidity. Laminate flooring still looks very much like hardwood. However, a laminate board is thinner and lighter than a hardwood floor plank. A laminate plank is usually only 3/8 of an inch thick.
If you need a board with a different thickness, you usually can obtain it from a hardwood supplier. For example, you may need particularly thin flooring if existing doors offer little clearance from the floor. Solid flooring is available in sizes as thin as 5/16 inch.
