Quick answer: Behr coverage per gallon
Most Behr Premium Plus Interior lists up to about 400 sq ft per gallon on smooth, primed drywall for one coat. Primer and exterior products are lower — always use the Coverage line on your specific can.
This page is the coverage chart — not a gallon calculator. To turn coverage into gallons, open how much Behr paint do I need or the Behr paint coverage calculator. For the full Behr paint calculator Canada hub, start on the homepage.
Where to find coverage on the can
Look for "Coverage" or "Spread rate" — typically 250–400 sq ft per gallon for interior latex, lower for rough surfaces and exterior stain.
That number assumes one coat on a smooth, properly prepared surface. Multiply your total area by coat count before dividing.
Factors that reduce coverage
Our gallon tools include a waste allowance you can adjust. Ten percent is standard for walls; fifteen percent for complex rooms with many corners.
- Textured walls (orange peel, knockdown)
- Unprimed porous surfaces (new drywall, bare wood)
- Rolling vs spraying (spray often uses more product)
- Deep colors requiring thick application
- Cutting in waste and tray residue — add 10% buffer
Adjust coverage for your wall type
Enter your measured sq ft and a realistic coverage number in the Behr paint coverage calculator — not the marketing maximum.
- Smooth primed drywall: use label high end (~400 sq ft)
- Orange peel texture: use ~300 sq ft/gallon
- Unprimed repairs showing through: lower effective coverage
- Spray vs brush: spray can list higher — brush/roll uses more
Behr paint coverage per gallon (typical ranges)
Behr does not publish one coverage number for all products — each can lists its own sq ft per gallon. These ranges help you sanity-check the label before you enter the number in a gallon tool.
- Behr Premium Plus Interior (walls): often up to 400 sq ft/gallon on smooth, primed drywall
- Behr Premium Plus Ultra / Marquee: similar on flat walls; deep colours may need more product
- Behr ceiling flat: commonly 350–400 sq ft/gallon
- Behr primer: typically 250–350 sq ft/gallon — lower than finish paint
- Behr exterior: often 200–300 sq ft/gallon on wood siding
Behr Premium spray can coverage (11–12 oz)
Searches like “Behr Premium 12 oz spray paint coverage square feet” and “11 oz spray paint coverage per can” are about the can label — not gallons. Behr Premium spray cans typically list coverage in square feet per can (often roughly 10–25 sq ft depending on colour, surface, and coats). Always use the Coverage line on your specific can.
For a small project, divide your paintable sq ft by that per-can figure to estimate how many spray cans to buy. For whole rooms, switch to gallon math on how much Behr paint do I need or the Behr paint coverage calculator.
- Read sq ft per can on the Behr Premium spray label (11 oz and 12 oz sizes differ by product)
- Plan extra cans for primer+paint combos and textured metal or wood
- Clear gloss and specialty sprays often cover less than flat colours — check the can
Behr Premium Direct to Metal (DTM) coverage per gallon
“Behr Premium Direct to Metal paint coverage per gallon” is a label question: DTM products usually list lower sq ft/gallon than interior wall latex (often roughly 250–350 sq ft/gallon on bare or primed metal, depending on product and surface). Use the DTM can’s Coverage line — do not use the wall-paint chart above.
Enter that DTM number in the Behr paint coverage calculator with your measured metal area for gallons to buy.
Use Behr label numbers in our gallon tools
If you searched “Behr paint coverage calculator,” open the interactive Behr paint coverage calculator and set sq ft per gallon to the exact figure on your Behr can. That matches what a brand-specific tool would do — without tying you to one manufacturer. This chart page stays for reference ranges only.
How much Behr paint do I need from coverage?
Take paintable sq ft × coats ÷ label coverage. Example: 384 sq ft walls × 2 coats ÷ 400 sq ft/gallon ≈ 1.9 → buy 2 gallons of Behr interior. Prefer a tool that also adds waste and rounds to store sizes? Use how much Behr paint do I need.
Prefer coverage-only math (one coat at a time)? Use the Behr paint coverage calculator. Both tools share the same Canadian DIY defaults as our paint calculator Canada homepage.
