The sheen spectrum, briefly
Paint finishes generally run from flat or matte, through low-sheen and satin, up to semi-gloss and gloss. As sheen increases, so does light reflection, durability and how easy the surface is to wipe clean — but so does the visibility of any imperfections in the wall underneath, since gloss highlights surface flaws that a flat finish tends to hide.
That trade-off — hide flaws versus resist wear — is really the whole decision in a nutshell, and it plays out differently room by room.
Living areas and bedrooms
Low-sheen and matte finishes are the standard choice for living rooms, bedrooms and hallway walls that aren't under heavy daily contact. They give a soft, even look that suits most modern interiors and hides minor surface irregularities well. The trade-off is that they mark more easily and are somewhat harder to spot-clean without a slight sheen difference showing where you've wiped.
Kitchens, bathrooms and laundries
Anywhere that deals with moisture, steam or grease benefits from a step up in sheen — typically satin or semi-gloss. These finishes resist moisture better, wipe clean more easily, and hold up to the kind of daily contact kitchens and bathrooms get. It's part of why cabinetry and trims are almost always finished in a higher sheen than the surrounding walls.
The finish that looks 'nicest' on a paint chip isn't always the one that performs best on the wall it's actually going on.
Trims, doors and skirting boards
Semi-gloss is the near-universal choice for trims, doors and skirting boards, regardless of the wall finish around them. These are the surfaces that get bumped, knocked and cleaned most often, and the slightly higher sheen also helps them read as a deliberate accent against a flatter wall colour rather than blending in.
Ceilings
Ceilings are almost always flat or matte, for a practical reason: any sheen at all tends to show roller marks and minor surface unevenness under raking light from windows, which is far more noticeable overhead than at eye level on a wall.
When in doubt, ask what the room actually does
The simplest way to land on the right sheen is to think about how the room is used day to day, rather than picking purely on how a sample looks under showroom lighting. We factor sheen into every colour consultation for exactly this reason — the right combination of colour and finish is what makes a repaint look considered rather than just 'painted'.
