How to Measure for Flooring

Installing new flooring is an exciting home renovation project that can truly transform the look and feel of your living spaces. However, before you can select your new floors and begin the installation, you need to accurately measure the room.

Precise measurements are critical for determining the proper amount of flooring materials required and avoiding costly overages or underages. How to measure for flooring in a room? Measuring for new floors may seem straightforward, but there are many factors to consider beyond just length and width.

You’ll need to account for offsets, curves, alcoves, and any other unique room features. With careful measuring upfront, you can ensure your new floors are installed beautifully with no gaps or awkward transitions.

Whether you plan to tackle the floor installation yourself or hire professional installers, taking the time to comprehensively measure the space is a vital first step. This guide will walk you through the essential steps for accurately measuring for your upcoming flooring project.

How to Measure for Flooring

To measure for flooring, first measure the room’s length and width, then multiply to get square footage. Add about 10% extra for coverage. Consider any patterns or odd shapes by measuring sections separately. 

Account for waste when cutting pieces. If unsure, seek guidance from a flooring professional to ensure accuracy. This approach helps you purchase the right amount without overspending or running short, ensuring a smoother installation process and avoiding last-minute headaches.

Basic Concepts

For square or rectangular rooms, measure the length and width and calculate the area by multiplying the dimensions. If the room has an irregular shape, break it into rectangular sections. Measure each section’s dimensions and calculate its area, then sum the areas. Account for obstructions by measuring and subtracting their area.

Add 5-15% extra to the calculated area to accommodate cuts, wastage, and pattern matching required by the flooring type. Use a measuring tape to take measurements, and mark the dimensions with chalk on the floor. Sketch a layout labeling the key measurements. 

When calculating for specific flooring materials like planks or strips, consider the minimum width and patterns. This ensures proper coverage and prevents unsightly transitions. 

How to measure flooring for laminate

For laminate, you need to account for larger expansion gaps of 1/4″ to 1/2″ around the perimeter of each room. This means calculating approximately 10% extra square footage into your measurements to allow for the waste from cutting planks.

Laminate also requires an underlayment layer which gets rolled out first, adding to the total square footage needed. Additionally, you may want to purchase extra boxes to ensure you have enough end planks to continue patterns seamlessly between rooms.

How to measure flooring for vinyl

For vinyl, the expansion gaps can be smaller at 1/8″ to 1/4″, resulting in less wasted material from cutting planks along edges – usually just 5-10% overage maximum. 

Some vinyl floors can go directly over the subfloor without an underlayment layer. Vinyl tiles or planks also allow you to start and stop patterns between adjoining rooms more easily without needing to precisely match planks.

Units of Measurement

Flooring materials are sold by area in square feet (sq ft) or square meters (sq m). Stick to one consistent unit; don’t mix square feet and square meters calculations. 

How to measure flooring in square feet/meters

Understand definitions: 

  • 1 sq ft = area of 1×1 ft square
  • 1 sq m = area of 1×1 m square

If converting units, use 1 sq ft ≈ 0.093 sq m carefully. 

Note which unit your supplier uses – carpet often square feet, tile square meters. Match measurements to the supplier’s unit to avoid mismatches when ordering.

Tools Needed for Measuring

  • Long (25 feet+) sturdy tape measure
  • Basic calculator
  • Notepad and pen to record dimensions and sketch layouts

For larger or complex spaces, you can use laser measure for point-to-point distances or a measuring wheel that rolls and tracks linear distances.

A construction calculator that automatically determines areas of irregular shapes is an advanced tool you may find useful.

Before you start the process, check if the tools are calibrated and in good working condition, replace any damaged or faulty equipment, and invest in quality measuring tools for precision and accuracy.

Step-By-Step Guide to Measuring Square or Rectangular Rooms

Measure the longest wall for length and the opposite widest wall for width. Multiply the length by the width to calculate the area in square feet or square meters. Then, add 5-10% extra area to cover cutting waste from fitting flooring. More intricate layouts may need 15% or more extra, while basic rectangles may require as little as 5%. Here are the steps:

  1. Find the longest wall and measure the length wall-to-wall.
  2. Find the opposite widest wall and measure the width wall-to-wall.
  3. Double-check length and width measurements.
  4. Calculate area = length x width.
  5. Add percentage to the area for cutting waste:
  • 5-10% for rectangles
  • 10-15% for rooms with offsets
  • 15%+ for very intricate layouts

Handling Irregularly Shaped Rooms

Break irregular room shapes into rectangular or square sections. Measure the length and width of each section, then calculate its area. Add all the section areas together to get the total area. For spaces with alcoves or bay windows, measure the main rectangular area separately from the alcove or bay area, then combine them.

Sketch a layout and label each section to avoid miscounting areas. Take your time and be systematic when measuring angles and offsets. For L-shaped rooms or those with multiple angled sections, divide them into two or three rectangles, then sum their areas.

Planning Your Flooring Purchase

Share room measurements or sketches with flooring suppliers or professional installers so they can calculate accurate material estimates with proper allowances. Verify their calculations make sense based on your measurements. 

Discuss room specifics like angles, alcoves, and patterned layouts that impact material needs. Most recommend 5-10% overage (15%+ for patterns). Also, calculate linear feet needed for trim pieces like baseboards in addition to floor area. Reviewing everything in detail will prevent surprises and ensure a smooth installation.
