What is Gloss?
Gloss is an aspect of the visual perception of objects that is as important as color when considering the psychological impact of products on a consumer.
It has been defined as ‘ The attribute of surfaces that causes them to have shiny or lustrous, metallic appearance.’
The gloss of a surface can be greatly influenced by a number of factors, for example the smoothness achieved during polishing, the amount and type of coating applied or the quality of the substrate.
It is important therefore that gloss levels are achieved consistently on every product or across different batches of products.
Gloss can also be a measure of the quality of the surface, for instance a drop in the gloss of a coated surface may indicate problems with its cure, leading to other failures such as poor adhesion or lack of protection for the coated surface.
It is for these reasons that flooring manufacturers monitor the gloss of their products.
How is gloss measured?
Gloss is measured by shining a known amount of light at a surface and quantifying the reflectance. The angle of the light and the method by which the reflectance is measured are determined by surface and also aspect of the surface appearance to be measured.
ISO 2813 and ASTM D523 (the most commonly used standards) describe three measurement angles to measure gloss across all surfaces. Gloss is measured in gloss units (GU) and is traceable to reference standards held at NIST (Canada) or NPL (UK).
Universal Measurement Angle: 60°
All gloss levels can be measured using the standard measurement angle of 60°. This is used as the reference angle with the complimentary angles of 85° and 20° often used for low and high gloss levels respectively.

Who measures the gloss of hardwood flooring?
Gloss of hardwood flooring is typically measured at 60°.
Wood flooring manufacturer’s finishing lines have been using gloss meters for decades to measure the gloss level in quality control (QC) to ensure they always achieve a consistent, quantifiable visual finish.
|Up to 20 GU||Low Gloss|
|21-40 GU||Medium Gloss|
|41 GU and up||High Gloss|
Wood flooring distributors want to check their inventories to maintain the integrity of their inventory allocation. When wholesale orders are filled from two or more different production lots or “runs”, a gloss meter can verify if the finish of that run is close enough to a preceding run to send out on a job site.
Wood flooring dealers are always comparing the finish of their showroom samples to the actual product they receive from distributors and manufacturers. Gloss meters can help verify a major inconsistency that might negatively impact a project installation later.
Wood flooring installation contractors who perform sand and finish operations on site (aka “site-finishers”) would be interested in knowing the gloss level of the finish type they are using; water-based urethanes,
oil-modified urethanes, deep penetrating oil, conversion varnishes, etc.
Wood flooring inspectors get asked on occasion to verify gloss levels from two or more conflicting lots or runs to establish whether or not there was a problem with a previous order fulfilment. Mixing production runs does not always look good to a discriminating consumer with a sharp eye. This happens more often than people realize.
