What is paint sheen?
Paint sheen is the degree of light reflection from a painted surface, measured on a scale from flat (matte) to glossy, which affects appearance, washability, and durability.
Sheen refers to how much light bounces off a painted surface rather than being absorbed. It runs on a spectrum from flat or matte (minimal reflection) through eggshell, satin, and semi-gloss to high-gloss (maximum reflection). The sheen you choose changes how a room or exterior looks and performs over time.
Higher sheens reflect more light, creating a brighter, more luminous finish. They also resist stains and moisture better, making them easier to wipe clean, which is why kitchens, bathrooms, and trim often use satin or semi-gloss. Flat and matte sheens absorb light and hide surface imperfections, wall texture, and prep work flaws, but they resist scrubbing and moisture. Eggshell sits in the middle, offering subtle sheen with decent cleanability.
The choice affects not just appearance but how long the finish lasts. Higher-sheen paints tend to be more durable and resist fading, while flat finishes can show wear patterns and marks more readily. When planning an interior or exterior project, understanding sheen helps balance the look you want with the maintenance your surfaces will endure.
