Paint sheens explained: flat to high-gloss

Flat, eggshell, satin, semi-gloss and gloss compared: where each sheen belongs, how well it cleans, and how it hides or shows flaws.

The short answer

Sheen is how much light a dried paint film reflects. The scale runs from flat, with no shine at all, through matte, eggshell and satin, to semi-gloss and gloss. The more shine, the easier the surface is to wipe clean, and the more it shows dents, patches and roller marks. A common plan for a US home is flat on ceilings, eggshell or matte on living room and bedroom walls, satin in busy rooms such as kitchens, baths and hallways, and semi-gloss on trim and doors. Sheen is not a reason to change your quantity estimate, so plan it with the paint calculator as usual.

Names and exact gloss levels vary between brands. Some makers add in-between finishes such as velvet, pearl or low-lustre, and each places them a little differently on the scale. Read the product's own description when choosing between two neighbors on the scale.

The five main sheens

Flat has no gloss. It is the most forgiving finish on uneven drywall, patched walls and ceilings, because it scatters light instead of bouncing it back, and manufacturers describe it as hiding surface imperfections well. The trade-off is upkeep: stains are harder to remove from low-sheen paint, and scrubbing can burnish the surface into shiny spots. It suits ceilings, adult bedrooms and formal rooms that rarely get touched.

Matte and eggshell sit just above flat. They keep a low, soft look but stand up to wiping better, which makes eggshell the everyday wall finish in many homes. Manufacturers place it in bedrooms, family rooms and hallways as a middle ground between durability and low luster. Matte from premium lines can be highly washable too, so check the product data rather than assuming every matte is fragile.

Satin has a visible soft glow. One maker describes it as having high stain and scrub resistance and recommend it for kitchens, bathrooms, laundry rooms, hallways and children's rooms. Because it reflects more light than eggshell, patches and uneven rolling are easier to see, so smooth, well-prepared walls matter.

Semi-gloss is the usual choice for trim, doors, cabinets and wet rooms. It cures to a smooth surface that stands up to repeated cleaning, but it reveals more surface flaws. Gloss and high-gloss go further still: the best stain and scrub resistance, used on doors, cabinets, railings and trim, and the least forgiving of dents and brush marks. One maker warns against using high gloss on any area that is not completely smooth.

Choosing a sheen room by room

Start with how the surface is used, then with how good it looks under a light. A ceiling is rarely touched and is seen at a low angle under lamps, so flat is the standard choice and hides small seams and patches. The ceiling paint calculator works out how much a ceiling needs.

Living rooms and bedrooms get light wear. Eggshell or matte gives a calm, low-shine look while still letting you wipe off a fingerprint. If the drywall has visible tape joints or many patched nail holes, lean toward the flatter end.

Kitchens, bathrooms, laundry rooms and kids' rooms face grease, steam, splashes and hands. Satin is the common choice there because it holds up to frequent wiping without the full shine of semi-gloss. In a small bathroom without good ventilation, look for a product marketed for bathrooms rather than relying on sheen alone.

Trim, doors and cabinets take the most knocks and cleaning. Semi-gloss is the default because it is durable and easy to clean, and the contrast between glossy trim and lower-sheen walls makes the woodwork stand out. Expect to sand and fill more carefully before painting, because every dent will show.

How sheen hides or shows flaws

Shiny paint acts like a weak mirror. Light hitting a bump, a filled hole or a ridge from a roller edge bounces off at a different angle from the flat wall around it, and your eye picks up the change. Flat paint scatters light in all directions, so those small changes in angle are much harder to see. That is why flat and matte finishes are recommended for uneven or textured walls, and why glossy finishes need careful prep and even application.

Sheen also affects touch-ups. A spot repair in glossier paint tends to show as a patch with a slightly different shine, while flat paint blends more easily. If a patch shows, repainting the whole wall corner to corner with the same product and finish usually gives a consistent result. Sheen can also make a color look slightly different, so test a sample in the finish you plan to use.

Does sheen change how much paint you need?

Not in a way you should plan around. The manufacturer sources checked for this guide give no lower spread rate for glossier sheens; they describe flat and matte finishes as having excellent hide, and satin as having good hide. Coverage on the label is set by the product line, not the sheen name, so use the square feet per gallon stated on the can you buy. What changes the gallons is the surface, the color change and the number of coats, which the paint calculator already accounts for. The guide on how paint coverage works covers those factors.

Worked example

Take a bedroom 12 ft by 10 ft with 8 ft walls and one door, to be painted in three sheens: flat on the ceiling, eggshell on the walls and semi-gloss on the baseboards and the door. Assume 400 sq ft per gallon and two coats everywhere.

Walls: 2 × (12 + 10) × 8 = 352 sq ft, minus 20 sq ft for the door, leaves 332 sq ft. Two coats is 664 sq ft, and 664 ÷ 400 = 1.66 gallons, which rounds to 1.7. One gallon leaves a remainder of more than half a gallon, so the plan is 2 gallons of eggshell. Ceiling: 12 × 10 = 120 sq ft. Two coats is 240 sq ft, and 240 ÷ 400 = 0.6 gallons, more than half a gallon, so the plan is 1 gallon of flat ceiling paint.

Trim: the perimeter is 2 × (12 + 10) = 44 ft. Leave out about 3 ft for the doorway, giving 41 ft of baseboard. At 6 inches (0.5 ft) high that is 41 × 0.5 = 20.5 sq ft. Add one face of the door at 20 sq ft for a total of 40.5 sq ft. Two coats is 81 sq ft, and 81 ÷ 400 = 0.2 gallons, which is no more than a quarter gallon, so the plan is 1 quart of semi-gloss. The shopping list is 2 gallons eggshell, 1 gallon flat and 1 quart semi-gloss. For which can sizes to choose, see the guide to paint can sizes.
