Before installing thin resilient flooring (such as luxury vinyl tile), the substrate flatness matters because the material is thin. A common flatness tolerance is no more than about 3/16 inch deviation in:
a.1 foot
b.10 feet
c.50 feet
d.100 feet
Explanation
Resilient flooring guidance commonly requires flatness within about 3/16 inch in 10 feet (and 1/32 inch in 1 foot) so bumps and dips do not telegraph or cause failures. Measuring over 1 foot is too short for that tolerance, and 50 or 100 feet is meaninglessly long.
