Hardwood Flooring Calculator Tips

To determine exactly how much hardwood flooring you need for your new wood floor, please fill in your desired specs into our calculator above. However, if you’re unsure what to enter, please keep the following hardwood flooring calculation tips in mind:

  • First, you have to calculate the square footage of the room. Hardwood flooring is typically sold by the square foot.
  • If you have a square or rectangular room, just measure the length and width in feet.
  • If your room is an irregular shape, break it up into smaller figures by dividing it into squares, rectangles, triangles and circles. This makes calculating the total square footage (area) much easier.
  • Area of A Square: Multiply the length of one side (should all be the same) by itself.
  • Area of A Rectangle: Length of room multiplied by the width of the room.
  • Area of A Triangle: Length of the base multiplied by the height, all divided by two.
  • Area of A Circle: Square (multiply it by itself) the radius and then multiply that number by 3.14 (Pi).
  • Molding: If you’d like molding, your hardwood flooring material costs will go up.
  • Always add 10% of materials to account for waste. Our hardwood flooring calculator includes that 10% waste.

Calculate How Much Wood You Need For Your New Floors

Whether you’re installing hardwood flooring on your own or hiring a flooring contractor, follow the steps below to ensure you buy the right amount of wood for your new floors:

  1. Preparation: Determine how many rooms need new wood floors.
  2. Hardwood Flooring Options: Determine if you want solid wood or engineered wood. Then decide what type of wood you want to install. More information on both choices is below.
  3. Calculate Square Footage of A Square Room: Square (multiply it by itself) the length of one side. Or, enter this number as the length and width into the wood flooring calculator above.
  4. Calculate Square Footage of A Rectangular Room: Multiply the length of the room by the width of the room. Or, enter these numbers into the lengths and widths in the wood flooring calculator above.
  5. Calculate Square Footage of A Triangular Room: Multiply the base length of the triangle by the height of the triangle. Then, divide this number in half.
  6. Calculate Square Footage of A Circular Room: Multiply the radius of the circle (half the diameter) by itself. Then, multiply that number by 3.14 (Pi).
  7. Calculate Square Footage of An Irregularly-Shaped Room: Divide the room into shapes mentioned above. Calculate the total square footage of each shape and add them together.
  8. Molding: Linear feet measures molding. To calculate, determine the perimeter of the room. As such, add together the lengths and widths around the room. Our wood calculator above automatically adds molding materials if you select it.
  9. Waste: If doing calculations by hand, add 10% to account for waste. Boards need to be cut and sadly, you won’t be able to use every square foot of the wood you purchase. If using our wood flooring calculator, 10% waste is included.

Why Hardwood Flooring

Carpet and tile used to be the dominant flooring choice across the U.S. However, hardwood flooring is taking over in rooms across the home. With the bathroom being the exception, hardwood flooring is a trendy flooring option in any room of the home, including bedrooms, living rooms, kitchens, basements and entries. Beyond being on trend, hardwood flooring brings a host of other advantages:

  1. Durable: Hardwood floors are very durable to everyday wear and tear. While tile is also durable, the same can’t be said for carpet.
  2. Low Maintenance: Hardwood floors are very easy to clean, unlike carpet. Cleanup is as simple as wiping down the floors with a rag or a light dusting after having people over. Spills, if you clean right away, do not stain. As anyone with carpeting knows, a stain is never easy to remove on carpet. Sadly, the same can't be said for certain types of tile.
  3. Options: You have plenty of flooring options when it comes to wood. From oak and pine to maple and walnut, there is a hardwood flooring type out there perfect for your home and budget.
  4. Valuable: Hardwood flooring is trendy right now and expert designers don’t see it changing anytime soon. Potential homeowners value real (solid), hardwood floors and will pay more for it. Therefore, if you plan on selling in the next five years, a hardwood flooring installation is a smart move.

Hardwood Flooring Cost Calculator

Now that you know what type of wood you’re using and how much to buy, you can determine how much your new hardwood floor will cost. According to our hardwood flooring cost calculator, most homeowners spend between $2,900 and $5,000 to professionally install new floors. This cost covers installation and materials.

The primary factors that affect your final hardwood flooring price are materials, labor, complexity of the job, type of wood, quality of wood and size of the room.

The easiest way to save money on any flooring installation is to DIY. Beyond your time, if you choose to install wood floors on your own, your only expense is materials.

  • Red Oak: This is a very popular type of wood. Its red color certainly makes it stand out compared to other wood floors. Red oak is very dense, which hides signs of wear and tear.
  • White Oak: Unlike its red sister, white oak resists wear and tear much more. If you need a durable flooring option, white oak is your answer.
  • Wide Plank Wood: These boards typically have a width wider than 5”. If you’d like a rustic and exotic appearance, go with wide planks.
  • Pine: This hardwood has a yellow/brownish color. You can purchase different grades of pine. Higher grades mean fewer knots appearing in the wood.
  • Walnut: This is an especially dark wood that is very durable and requires very little maintenance. Many homeowners install walnut floors in modern or traditional homes.
  • Brazilian Cherry: As you might expect, this flooring comes from its natural cherry color. When exposed to light, the colors darken. It’s very hard, making is usable for both residential and commercial properties.
  • Maple: Maple is one of the strongest hardwoods on the market. In fact, it can withstand almost anything you throw at it. The traditional maple shade is a light tan color.
  • Ash: This type of wood is popular for rustic and contrasting patterns in homes. The harder durability of ash is found in garden tools and other tools that take daily abuse.
  • Reclaimed Wood: No two pieces of reclaimed wood look the same. Many homeowners enjoy this unique characteristic. Reclaimed wood adds character like no other wood can. Buildings using reclaimed wood may be eligible for LEED certification.
  • Solid Oak: Solid oak is the most common type of wood flooring used in older homes. It’s very evident in rustic homes.

Solid Hardwood Or Engineered Hardwood Flooring

Beyond the type of wood you choose, you have to determine if you want solid hardwood (real wood throughout) or engineered hardwood floors. Before your purchase any wood for your new floors, consider the following:

Solid Hardwood Flooring

Solid hardwood floors are made from one, solid piece of natural wood. It’s the only material used, something engineered hardwood can’t say. Typically, solid hardwood is three quarters of an inch thick.

If you want the real thing, you should buy solid wood. Beyond the natural scent of real wood, solid wood is easy to refinish. Finally, solid wood is more durable than engineered woods.

On the downside, solid wood easily expands and contracts. Therefore, you can’t really install them in bathrooms. Furthermore, as you might expect, solid wood flooring is more expensive than engineered wood.

Engineered Hardwood Flooring

Engineered hardwood consists of several layers, with only the top and bottom consisting of real wood. The inner layers are made of plywood, high-density fiberboard or sometimes, actual hardwood.

Engineered wood can handle moisture, making it a popular choice for bathrooms and basements. Since engineered hardwood flooring requires only a thin slice of real wood as the top layer, the cost is much less than solid hardwood. Finally, engineered wood is very green. The trees for engineered floors grow much faster than those for solid hardwoods.

The primary drawbacks of engineered wood revolve around appearance, feel and value. Some homeowners claim they can tell a difference, especially when you walk on it. Additionally, if you sell your home, potential buyers will ask about the floors. Solid wood floors bring more value than engineered wood floors.
