Painting Estimate Guide

How to estimate painting jobs — pricing, production rates, and template essentials.

How to Estimate a Painting Job

Painting estimates are based on square footage of paintable surface area, not floor area. Walls, ceilings, and trim are estimated separately.

  • Wall area formula: (Room perimeter × ceiling height) – doors – windows
  • Ceiling area: Room length × width
  • Trim/baseboard: Room perimeter in linear feet
  • Labor production rate: 100–150 sq ft/hr for rolling walls, 50–80 sq ft/hr for cutting in

The #1 estimating mistake is measuring floor area instead of wall area. A 12×12 room has 384 sq ft of walls (not 144 sq ft).

Key Takeaways

  • Estimate by wall area, not floor area
  • Rolling production: 100–150 sq ft/hr
  • Cutting in: 50–80 sq ft/hr (slower, more precise)

Painting Estimate Pricing in 2026

Professional painters charge $2–$6 per square foot of wall area for interior painting, including labor and materials.

  • Interior walls (per room): $350–$800 per room (standard bedroom, 2 coats)
  • Interior trim/doors: $3–$8 per linear foot of trim, $75–$200 per door
  • Ceiling painting: $1–$3/sq ft
  • Exterior painting: $1.50–$4.00/sq ft
  • Cabinet painting: $3,000–$7,000 for a full kitchen

Prep work (patching, caulking, sanding, priming) accounts for 50–70% of total labor time on repaints.

Key Takeaways

  • Interior painting: $2–$6/sq ft of wall area
  • Cabinets: $3,000–$7,000 per kitchen
  • Prep = 50–70% of total labor time

What to Include in a Painting Estimate Template

A professional painting estimate should itemize rooms individually with separate lines for walls, ceilings, trim, and prep work.

  • Room-by-room breakdown: Square footage, number of coats, color
  • Prep work detail: Patching holes, caulking, sanding, priming
  • Paint brand/product: Specify the exact product (affects price and quality expectations)
  • Exclusions: Moving furniture, wallpaper removal, lead paint abatement
  • Timeline: Start/end dates, hours per day on site

Key Takeaways

  • Itemize rooms individually with sq ft
  • Specify paint brand/product in estimate
  • Detail prep work separately (major cost factor)

Painting Estimate Formulas

Wall Area = 2 x (Length + Width) x Height - (Doors x 20 sq ft) - (Windows x 15 sq ft)
Paint Needed = (Wall Area x Coats) / Coverage Rate

Where:

Coverage Rate
= 350-400 sq ft per gallon depending on paint type and surface texture
Labor Rate
= $25-$50 per hour depending on region and painter experience
Production Rate
= 150-200 sq ft per hour for a typical interior wall

Frequently Asked Questions

How much does it cost to paint a room?
The average cost to paint a standard 12x12 room is $300 to $800, depending on paint quality, number of coats, and labor rates in your area. DIY projects will cost less since you only pay for materials, typically $100 to $200.
How many gallons of paint do I need?
One gallon of paint covers approximately 350 square feet. A typical 12x12 room with 8-foot ceilings has about 380 sq ft of wall area, so most rooms need 2 to 3 gallons for two coats. Always round up to avoid running short mid-project.
How long does it take to paint a room?
An average-sized room takes 4 to 8 hours to paint, including prep work like taping, priming, and cleanup. Professional painters can often complete a room faster due to experience and better equipment.
Should I include primer in my estimate?
Yes, especially when painting new drywall, covering dark colors, or making a dramatic color change. Primer helps paint adhere better and provides more even coverage. Some premium paints include built-in primer, which can save a step.
What's the labor cost for painting?
Professional painters typically charge $25 to $50 per hour, or roughly $1.50 to $3.50 per square foot. Rates vary by region, complexity of the job, and whether the work is interior or exterior.
