How Many Boxes Of Flooring Do I Need Calculator? [2024]

How Many Boxes Of Flooring Do I Need Calculator? Installing new flooring can transform the look and feel of a room. However, determining the right amount to purchase can be tricky. Understanding flooring measurements and using a flooring calculator helps ensure you buy the correct number of boxes for your project. Buying too little means you’ll have to purchase more mid-project. Getting too much means wasted money on supplies you don’t end up using.

This guide explains key flooring terminology and measurements. It also walks through how to use flooring calculators to find the number of boxes needed for your unique space. Follow these tips, and you’ll buy the right flooring amount the first time.

Understanding Flooring Dimensions

Before using a flooring calculator, it’s essential to understand the dimensions and terminology listed on flooring packaging and descriptions. This includes:

  • Square feet – The area of a room measured in feet. Length x width. Knowing accurate room square footage is key for a flooring calculator.
  • Planks – Individual flooring pieces. Planks click together to cover the floor space.
  • Boxes – Flooring planks packaged together for sale. The number of planks varies based on plank size.
  • Plank length – The long side measurement of a plank. For example, some are 4 feet long or 8 feet.
  • Plank width – The short side measurement, usually around 5 inches wide.
  • Thickness – How thick the planks are, such as 1/4 inch up to 1/2 thick.

Understanding these terms ensures you purchase planks suitable for your room size and layout. It also allows accurate calculation of how many boxes you need.

Measuring the Room

The starting point for any flooring calculator is accurately measuring your room’s square footage. Make sure to calculate floor space requiring the new planks only. For example, exclude areas covering by furniture.

You need two measurements:

  • Length – Measure the room length in feet, rounding up to the next half or full foot. Measure the longest straight distance across the center of the room from one wall to the opposite wall.
  • Width – Measure the room width in feet at the widest point perpendicular to the length. Again, round up to the next half or full increment.

Multiple the length x width to calculate the room’s square footage. This number serves as the starting point for most flooring calculators. For accuracy, take measurements a few times and average the results.

Account for Other Flooring Elements

Floor space square footage calculates how much floor the planks cover. However, installing flooring involves more than just planks. Prepare to account for additional elements like underlayment, transitions between rooms, uneven wall lines, and leftover scrap pieces.

  • Underlayment – Required in many plank installations under the flooring to smooth imperfections. The underlayment square footage must match that of the planks. Calculate and order materials separately from the planks if not included.
  • Transitions – Cover gaps between flooring types, like connecting tile and hardwood floors. Order transition pieces separately based on linear footage.
  • Scrap – Created when cutting planks to fit the room, especially around irregular walls. Professionals recommend adding 5-15% extra for scrap waste.

While not increasing plank requirements, these extras impact the total supplies needed. Factor them into planning and budgeting for simplicity.

Using a Flooring Calculator

With accurate room measurements and an understanding of critical flooring dimensions, turn to a calculator tool to determine boxes required. Flooring calculators ask a series of questions about your project to provide a boxes needed estimate along with the amount of materials.

Here is the flooring calculator process in 6 steps:

  1. Enter room square footage.
  2. Input the plank width from product details. Many offer standard 5-inch wide planks.
  3. Enter the plank length. Options often range from 1-foot pieces up to 8-foot planks. Room size and layout impact ideal plank length.
  4. Note the number of planks contained in one box. Ranges from 15 pieces for longer planks to 30+ for shorter lengths.
  5. Factor in that professionals recommend buying 5-15% extra for scrap waste during the install process.
  6. The calculator runs the numbers to provide boxes required for purchase.

Flooring specialists recommend starting your planning by identifying the specific flooring product you want to install. Take the information from that manufacturer’s packaging details as inputs for the most accurate estimate of boxes needed.

Here is a manual formula for calculating boxes without an online calculator:

  1. Divide room square footage by plank width to get linear footage needed.
  2. Divide linear footage by plank length to determine total planks required.
  3. Divide total planks by pieces per box to calculate the number of boxes needed.

Both calculators and the formula offer estimates to use for planning and buying. Exact requirements vary based on room specifics and cutting required during installation. Many flooring experts recommend buying 5-10% extra as a buffer. Return unopened surplus boxes after completing your beautiful new floor.

Other Flooring Calculator Considerations

Keep the following additional tips in mind when planning for and purchasing flooring:

  • Grain direction – Many planks look best running in the same direction. Calculate and purchase enough to facilitate the ideal layout.
  • Multiple rooms – If installing flooring in multiple rooms or whole floors, calculate and purchase materials separately per space.
  • Irregular spaces – Significantly irregular room layouts make calculating difficult. Have extra product on hand to account for abnormal shapes.
  • Product availability – Check with the retailer to understand product availability for your timeline. Ordering well in advance ensures access and avoids mid-project delays.
  • Future repairs – Set aside 5-10% of flooring boxes in storage for future repairs in the case of water damage or other issues requiring plank replacements.

Leveraging Online Planning Tools

In addition to calculators for boxes needed, many leading flooring manufacturer and retailer websites offer enhanced online planning tools. These allow creating entire room flooring layouts to understand requirements and view how a style and color looks in your unique space.

After inputting room dimensions, these planning tools allow you to:

  • Build floor plans with exact wall lines.
  • Add flooring grain direction.
  • Insert transitions betweenflooring product types.
  • Experiment with different plank layout options including herringbone designs.
  • View plank edges and borders.
  • See how light reflects off two-toned planks.
  • Mix and match colors and patterns for custom looks.
  • Determine boxes needed for the computer-generated layout.

Take advantage of these powerful visualization tools for added assurance around your flooring purchase. Adjusting a digital layout is much easier than ripping out real planks after installing the wrong amount.

How do I calculate the square footage of my room?

To calculate square footage, measure the length and width of your room in feet, rounding up to the next half or full foot. Multiply the length by the width to get the square footage. Measure only the area that will be covered by the new flooring.

What information do I need about the flooring planks?

You’ll need to know the plank width, plank length, planks per box, and thickness. This information is included on the flooring packaging or product description.

How does plank length and width impact the number of boxes I need?

Planks that are longer and wider cover more square footage. So for the same size room, you’ll need fewer boxes of 8 ft. long planks compared to 1 ft. planks because you need fewer individual pieces to cover the space.

Do I need to order extra?

It’s recommended you purchase 5-15% more flooring than calculated to allow for cutting scrap waste and the possibility of future repairs.

Should I use an online flooring calculator?

Yes, flooring calculators are the easiest way to get an estimate of how many boxes you need. Enter your room size and plank dimensions for an estimate in seconds.

What other supplies do I need beyond the flooring?

Don’t forget to calculate and purchase underlayment, transitions between flooring types, and moldings to finish the project. These are not included in the flooring calculator estimate.

Can I get professional advice on calculating my order?

Yes, home improvement stores offer free in-store consultations to measure your space and help determine flooring requirements accurately. This gives added assurance you purchase the correct amount.
