\n

Vinyl flooring thickness involves two measurements: total plank thickness and wear-layer thickness. Check both before choosing a floor. A thicker plank does not always have a thicker wear layer.<\/p>\n

This guide covers SPC rigid-core flooring, a type of luxury vinyl plank (LVP). Learn how to compare 5.5\u20138 mm planks and 12 mil vs. 20 mil wear layers for your home or project.<\/p>\n

For the basics, read our SPC flooring buying guide<\/a>.<\/p>\n

Vinyl Flooring Thickness vs. Wear Layer: What\u2019s the Difference?<\/h2>\n

Millimeters Measure Total Plank Thickness<\/h3>\n

Overall plank thickness measures the full product in millimeters (mm). It includes the wear layer and may include an attached pad. Check the product sheet for what the total covers.<\/p>\n

This number helps you plan floor height, door clearance, and transitions to nearby floors. It does not tell you how thick the wear layer is.<\/p>\n

Mils Measure the Wear Layer<\/h3>\n

The wear layer helps protect the printed design beneath it. U.S. listings often measure it in mils<\/strong>: one mil equals one-thousandth of an inch.<\/p>\n

\n\n\n\n\n\n\n
Wear-layer label<\/th>\nThickness in millimeters<\/th>\n<\/tr>\n<\/thead>\n
12 mil<\/td>\nAbout 0.30 mm<\/td>\n<\/tr>\n
20 mil<\/td>\nAbout 0.51 mm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Product sheets may round these to 0.3 mm and 0.5 mm. The wear layer is already part of the total plank thickness; do not add it again.<\/p>\n

Comparing 5.5, 6.5, 7, and 8 mm SPC Flooring<\/h2>\n

Compare Total Thickness and Attached Pad Separately<\/h3>\n

Compare three figures: total thickness, wear layer, and attached pad. A thicker pad can increase total thickness without changing the wear layer.<\/p>\n

Check whether each product includes its pad in the total. A 7 mm plank does not necessarily have a thicker wear layer than a 6.5 mm plank. An 8 mm label alone does not prove better scratch resistance.<\/p>\n

Only add extra cushioning underlayment if the product\u2019s instructions allow it. The Resilient Floor Covering Institute<\/a> advises following the maker\u2019s rules for underlayment, moisture, and subfloor preparation.<\/p>\n

Check Finished Floor Height and Transitions<\/h3>\n

Moving from 5.5 mm to 6.5, 7, or 8 mm adds 1, 1.5, or 2.5 mm of plank thickness. Check these differences at doorways and where the new floor meets tile or another surface.<\/p>\n

In a California remodel, ask your installer to assess the final floor height after removal and preparation work. Thicker planks still need a subfloor that meets the product\u2019s flatness requirements.<\/p>\n

12 mil vs. 20 mil: What Should You Compare?<\/h2>\n

A 20 mil wear layer has more material above the printed design than a 12 mil layer. With other factors equal, it is worth considering for heavier use. It does not guarantee a longer lifespan or approval for commercial use.<\/p>\n

Wear, scratches, and dents are different types of damage. A thicker wear layer does not make a floor scratch-proof or dent-proof. Read how the warranty defines surface wear and which damage it excludes.<\/p>\n

How to Narrow Your Options for a Home, Rental, or Professional Project<\/h2>\n

Everyday Residential Rooms<\/h3>\n

A guest bedroom and a busy entryway face different demands. Consider a 12 mil option for a residential shortlist if the product allows that use. Compare it with 20 mil options based on traffic, care, style, and budget.<\/p>\n

Busy Households and Rental Properties<\/h3>\n

For high-traffic areas, give 20 mil options a closer look alongside the finish and approved use. Consider cleaning routines and frequent furniture moves.<\/p>\n

A rental is not automatically a commercial installation. Check how the maker defines its use, and keep the product name and SKU for future reference.<\/p>\n

Light Commercial and Contractor Projects<\/h3>\n

Start with the project requirements. Match the product\u2019s allowed uses to the space, traffic, and equipment. A 20 mil wear layer alone does not make a floor suitable for every shop or office.<\/p>\n

Record each selected SKU and its specs. Check any substitute against that record before ordering.<\/p>\n
