Paint Calculator for Bedroom 12x14 ft
Overview
Planning paint for a Bedroom 12x14 ft space (168 sq ft, 15.61 sq m) means balancing coverage, surface texture, and the number of coats. This page shows expected gallon counts at the U.S. standard 350 sq ft per gallon per coat, then walks through how to interpret the result for primer-needed walls, color changes, and accent areas like doors and trim.
Room Specifications
| Room Type | Dimensions | Area (sq ft) | Area (sq m) | +5% waste | +10% waste | +15% waste |
|---|---|---|---|---|---|---|
| Bedroom | 12x14 ft | 168 sq ft | 15.61 sq m | 177 sq ft | 185 sq ft | 194 sq ft |
How it Works
The estimator divides paintable area by 350 sq ft per gallon per coat. A 168 sq ft surface therefore consumes about 0.5 gallons for one coat and 1.0 gallons for two coats. Real-world coverage varies between 250 and 400 sq ft per gallon depending on porosity (drywall vs. masonry), roller nap, sprayer overspray, and humidity. The result already excludes ceiling area; subtract roughly 21 sq ft for each standard door and 15 sq ft for each window if you want a tighter estimate.

| ~0.5 gal | ~1.0 gal |
Reading Your Estimate
If the gallon estimate falls below 1, round up to a full gallon for color consistency across batches. Two coats are the default for any color change or unprimed drywall; a single coat works only when refreshing an identical color over a clean primed wall. Save the leftover gallon for touch-ups — match codes can shift after a year of UV exposure, so the original can is the safest reference.
Other Bedroom Sizes
| Size | Area (sq ft) | Estimate |
|---|---|---|
| 10x10 ft | 100 sq ft | ~0.3 gal / ~0.6 gal |
| 12x12 ft | 144 sq ft | ~0.4 gal / ~0.8 gal |
| 12x14 ft | 168 sq ft | ~0.5 gal / ~1.0 gal |
| 14x16 ft | 224 sq ft | ~0.6 gal / ~1.3 gal |
| 16x20 ft | 320 sq ft | ~0.9 gal / ~1.8 gal |
Adjacent Sizes
Compared with neighbouring sizes in the same room category, a 168 sq ft footprint sits between smaller and larger options shown in the size table below. Stepping up to the next size class typically adds 0.3–0.7 gallons per coat, while stepping down saves the same range. Buying a single 5-gallon bucket is more economical than several 1-gallon cans once the requirement exceeds 4 gallons, but only if you can use the paint within shelf life.
Who Uses This Page
Homeowners reach this calculator before quoting interior painters, ordering low-VOC paint for nurseries, or repainting rentals between tenants. Contractors use it to confirm the line item on a remodel bid for a Bedroom of this footprint. Knowing the exact gallon count avoids storage of unused paint, which loses warranty coverage and can dry out in unsealed cans.
Frequently Asked Questions
How many gallons of paint for Bedroom 12x14 ft?
For walls totaling 168 sq ft of paintable area, plan for about 0.5 gallons with one coat and 1.0 gallons with two coats. Add 10% buffer for cuts and touch-ups.
Should I always do two coats?
Two coats are standard for color changes, fresh drywall, or strong colors like deep reds and navy. Single coat is acceptable only when refreshing the same color on previously painted, primed walls in good condition.
Does this include the ceiling?
No. The 168 sq ft figure here is for walls only based on a typical 8 ft ceiling height. Ceilings add roughly the same area as the floor plan (12x14 = 168 sq ft) if you plan to paint them.
What primer do I need first?
Use a stain-blocking primer on drywall patches, water-damaged areas, and over dark colors. Tinted primer (toward the topcoat color) reduces the topcoat to one finish coat on most walls.
How much extra paint should I buy?
Add 10% for cuts, drips, and future touch-ups. For textured walls (knockdown, orange peel) increase to 15% because the rougher surface area absorbs more paint than the nominal square footage suggests.
