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

Hardwood flooring comes in many thicknesses.

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

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.

Non-Standard Options

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.
