Cabinets are counted, not measured
Nobody estimates a kitchen by pulling a tape across the wall. Cabinet paint is bought against a count of doors and drawer fronts, because that is where nearly all of the surface area lives and because doors get coated on both faces. A mid sized kitchen has somewhere between 150 and 250 square feet of paintable cabinet surface, which sounds tiny next to a bedroom, and yet people run short constantly. The reason is that cabinets take three coats minimum and the spray losses are heavy.
The formula
- Door area = door count x average door area x 2 faces
- Drawer area = drawer front count x (front area + edges)
- Face frame area = exposed cabinet elevation – door and drawer area
- Add exposed end panels, toe kicks if painted, and the front edges of the boxes
- Gallons = (total area x 3 coats) / effective coverage
The three coats are not negotiable on a color change: one bonding primer and two finish. Cabinet enamel is applied deliberately thin so it levels and cures hard, so you are not going to bully it into two.
Worked example: 22 doors, 9 drawers
A typical L-shaped kitchen with 16 linear feet of upper cabinets and 18 linear feet of base cabinets.
- Doors: average 12 in x 30 in = 2.5 sq ft. 22 doors x 2.5 x 2 faces = 110 sq ft
- Drawer fronts: 22 in x 6 in plus edges, about 1.2 sq ft each. 9 x 1.2 = 11 sq ft
- Face frames and stiles: 20 sq ft
- Exposed end panels: two base ends at 5 sq ft, one upper end at 2.5 sq ft = 13 sq ft
- Front edges of boxes and shelf fronts: 8 sq ft
- Total: 162 sq ft
Now apply the coats. Cabinet enamels often state 350 to 450 sq ft per gallon, but that is a theoretical rate on a flat panel. Sprayed through a fine finish tip with normal overspray loss, plan on 250 to 300 sq ft per gallon. We use 275.
- Primer: 162 / 275 = 0.59 gallons. Buy 1 gallon.
- Finish, two coats: 324 / 275 = 1.18 gallons. Buy 1 gallon plus 2 quarts.
Brushing and rolling instead of spraying moves the effective rate up to roughly 325 sq ft per gallon, so a brushed job of this size needs about a gallon and a quart of finish. You save material and you pay for it in finish quality.
Quick sizing by kitchen type
| Kitchen | Doors | Drawer fronts | Total area | Primer | Finish (2 coats) |
|---|---|---|---|---|---|
| Small galley | 12 | 5 | ~90 sq ft | 2 qt | 1 gal |
| Small L-shape | 16 | 7 | ~120 sq ft | 2 qt | 1 gal |
| Mid L-shape | 22 | 9 | ~162 sq ft | 1 gal | 1 gal + 2 qt |
| Large U-shape | 30 | 12 | ~215 sq ft | 1 gal | 2 gal |
| Large kitchen plus island | 38 | 16 | ~280 sq ft | 1 gal + 2 qt | 2 gal + 2 qt |
Add roughly 10 percent if you are painting the inside faces of the doors a different color than the outside, and add about 40 percent to the whole number if you are painting cabinet interiors, which is a lot of fiddly area for very little visual return.
Two facts that decide whether this job lasts
Degreasing beats primer. Kitchen cabinets around a range accumulate a film of aerosolized cooking oil that is invisible and that no primer will bond through. The sequence that actually works is a strong detergent or degreaser wash, a rinse, then a scuff sand to around 180 to 220 grit, then a vacuum and tack. When we have seen cabinet jobs peel at the six month mark, it has almost always traced back to a skipped degreasing step, not to the paint. A bonding primer is still needed on top of that, because most factory cabinet finishes are catalyzed conversion varnish, which is a hard nonporous film that ordinary primer has nothing to grab.
Dry to touch is not cured. Waterborne alkyd and urethane enamels, which are what most people use on cabinets now, are typically handleable in a day and recoatable within a few hours, but they keep hardening for weeks. Many labels state full cure at around 21 to 30 days. Doors rehung and closed against soft paint will block, meaning the two surfaces stick together and tear when opened. Leave felt bumpers off, or better, leave the doors off entirely for as long as the household will tolerate it, and do not stack anything against a painted face.
Practical ordering notes
- Buy the finish in one purchase so it is one tint batch. Cabinet whites are pale enough that a batch difference between the uppers and the island is genuinely visible under undercabinet lighting.
- Keep a quart of the finish for touch-up. Cabinets get dinged, and the touch-up quart is worth more than the small savings from buying exactly enough.
- If you are spraying, the material you lose to the hose, the pot, and the flush is real. On a job this small that overhead is a meaningful fraction of a quart, which is another reason we round up rather than down.
