mm vs mil: The Confusion Behind Measuring Flooring Thickness

A Comprehensive Guide to Mils, Millimeters and Thou

Flooring thickness is an important factor when choosing the right flooring option for your home. However, the units used to measure flooring thickness can often create confusion, particularly between luxury vinyl plank, laminate, and sheet vinyl flooring. To clear up any confusion, this guide will provide a comprehensive understanding of the different units used to measure flooring thickness and how they impact the overall quality of the flooring.

The millimeter (mm), equivalent to 1/1000 of a meter, is the most commonly used unit to measure the thickness of laminate flooring. Laminate is typically between 7mm to 12mm thick, with the 12mm option falling just short of 1/2 inch.

On the other hand, the term “mil” is used to measure the thickness of sheet vinyl flooring. This unit is equivalent to 1/1000 of an inch, referred to as “thou” outside the USA. Engineers in the US have also started using “thou” to avoid confusion with millimeters. The term mil originated during the industrial revolution as a streamlined way for engineers to communicate in tenths instead of fractions like 1/8’s and 1/16’s. Today, mils are used to measure everything from aluminum foil to credit cards, including vinyl flooring. To give you a visual reference, a dime is about a millimeter thick, and just over 39 mils. Vinyl flooring is usually between 50 to 125 mils thick.

It’s important to note that the thickness of vinyl and laminate flooring does not determine its quality. Factors like density, construction, and thickness should all be considered when comparing flooring products.

In conclusion, whether you’re choosing between luxury vinyl plank, laminate or vinyl flooring, understanding the units used to measure flooring thickness is key to making an informed decision. With this guide, you’ll have a clearer understanding of mils, millimeters and thou, and how they impact the quality and performance of your flooring.
