Calculateur de Coût de Peinture

For DIY painting, a 10x12 or 12x14 room typically costs between $60 and $150 for 2 to 3 gallons of quality paint and basic supplies (tape, roller covers, drop cloths). Hiring a professional painter usually costs between $400 and $900 including labor, wall prep, and materials.

Professional interior painters typically charge between $1.50 and $3.50 per square foot of wall surface area. High ceilings, extensive drywall repair, trim/crown molding, and dark-to-light color transitions will push rates toward the higher end of the range.

A standard 10x12 or 12x14 bedroom with 8-foot ceilings has approximately 350 to 420 square feet of net wall area. Applying 2 full coats requires between 2 and 3 gallons of interior paint.

Budget paint ranges from $20 to $30 per gallon, standard mid-grade paint costs $35 to $50, and premium zero-VOC washable paint (such as Sherwin-Williams Emerald or Benjamin Moore Regal Select) costs $65 to $90+ per gallon. Premium paints cover better, clean easier, and often eliminate the need for an extra coat.

Primer is recommended when painting bare drywall, covering water/smoke stains, transitioning from oil to latex, or making drastic color shifts (e.g., navy to off-white). A gallon of dedicated PVA or stain-blocking primer costs $20 to $35 and reduces the amount of expensive topcoat paint required.

Paint rollers and brushes absorb a significant volume of liquid during application. A 10% buffer prevents running out of paint on the final wall section and ensures you have identical-batch leftover paint for future scuff and scratch touch-ups.

You can save 15% to 30% on labor costs by handling preparation yourself: moving furniture to the room center, removing switch plates and outlet covers, wiping down dirty baseboards, and patching small nail holes before the painters arrive.
