Understanding your result
The headline is the recommended level, and the line under it gives its short description. The tiles give the joint compound and the finishing labour range at that level for the area you entered.
The table gives the reasons in order: the starting point for the room, then each thing that moved it, gloss paint or raking light up, texture or tile down, your priority either way. Where two answers conflict, the stricter one wins, except that a priority for lowest cost can bring a Level 5 back to Level 4 when nothing about the room demands the skim.
The bars show the finishing labour for Levels 2 to 5 side by side, so the cost of the recommendation is clear next to the alternatives. What each level involves, pass by pass, with the days, is on the finish level planner; the compound in pails or bags is on the joint compound calculator; and the whole job’s cost on the cost estimator.
How we calculate this
The levels and their recommended uses are from the Gypsum Association’s GA-214, listed on the levels of finish table. The finishing cost uses the site’s shared cost-survey ranges, with our level shares; it covers finishing labour only, not hanging or materials.
The assumptions behind the numbers
| Assumption | Default | Where it comes from |
|---|---|---|
| Levels by use and surface | As in the formula | Gypsum Association GA-214 recommendations |
| Finishing labour at Level 4 | $0.80 to $1.50 per sq ft | Published cost guides, 2024–2025 |
| Level 5 skim | + $0.50 to $1.50 per sq ft | ThePricer |
| Level shares | L2 0.5, L3 0.75 of Level 4 | Our estimate |
| Compound | Level coverage per 100 sq ft | USG data pro-rated; see the coverage table |

The selector does not judge light you have not described; walk the room at the time of day it gets the most sun. It does not cover commercial specifications, where the architect names the level, or fire-rated assemblies, whose listings require at least taped joints regardless of appearance. The levels and how to tell them apart on a wall are in the guide to the levels of finish; how level shows up in a price is in the guide to what contractors charge.
Two worked examples
A 650 sq ft living room with flat paint and a wall of west-facing windows
- Start: Level 4 for a living space
- Raking light from the windows: Level 5
- Level 5: 9.1 gallons of compound; finishing labour $845 to $1,950 against $520 to $975 at Level 4
The skim coat costs about the same again as the finishing to Level 4. Under flat paint, some owners skim only the window wall; the selector’s answer is for the whole room.
A 900 sq ft garage with a knockdown texture
- Start: Level 2 for a garage
- Heavy texture: Level 3
- Level 3: 6.3 gallons; finishing labour $540 to $1,013
Level 3 gives the texture a sound base without paying for passes the texture will hide.
Where to find your inputs
Room. What the room is used for, or what the surface is.
Paint or texture. From the painter’s specification or your plan.
Light. Stand in the room in the afternoon; light skimming along a wall is raking light.
Area. The board area, for the cost bars.
Common mistakes
- No level in the quote. Write it in.
- Level 4 under gloss. Every ridge shows.
- Level 5 under knockdown. Money hidden by texture.
- Ignoring the windows. Raking light is the most common reason for Level 5.
- Garage at Level 4 by default. Level 2 is the usual garage finish unless it will be a living space.
- Judging at night. Look at the walls in daylight before you decide.
Questions people ask
- What drywall finish level do most homes use?
- Level 4 for painted walls and ceilings in living spaces, with flat, matte or eggshell paint. It is the standard in most quotes when no level is named, but ask, because some contractors mean Level 3.
- When do I need a Level 5 finish?
- Under semi-gloss or gloss paint, on walls with strong side light from large windows, skylights or wall-washer fixtures, and on feature walls where any flaw would show. GA-214 recommends Level 5 for those conditions.
- What finish level for a garage?
- Level 2 is usual for a garage, storage room or utility room where appearance does not matter, and is enough for fire taping. If the garage will be painted and used as a workshop or living space, Level 3 or 4.
- What finish level under texture?
- Level 3 under a medium or heavy texture such as knockdown, which hides what a fourth pass would smooth. Under a light orange peel, Level 4.
- What finish level behind tile?
- Level 2 for tile on walls outside wet areas: tape and one coat give a flat, sealed surface for the thinset. In tub and shower areas, tile goes on cement board or another tile backer, not gypsum.
- How much more does a higher finish level cost?
- In finishing labour, each level adds a pass: Level 3 about three quarters of Level 4's finishing cost, Level 2 about half, and Level 5 adds a skim coat of about $0.50 to $1.50 per square foot. The bars on the result show the four levels for your area.
