How Our Trim Paint Calculator Works
Our trim paint calculator uses precise mathematical formulas to determine how much paint you'll need for your trim project. Here's a step-by-step explanation of the calculation process:
Step 1: Calculate the surface area of each trim section
For each trim section, we convert the width from inches to feet, then multiply by the length:
Area (sq ft) = Length (ft) × Width (inches) ÷ 12
Step 2: Total all trim sections
We add up the square footage of all trim sections to get the total area:
Total Area = Sum of all individual trim section areas
Step 3: Account for multiple coats
The total paint area is multiplied by the number of coats:
Paint Area = Total Area × Number of Coats
Step 4: Calculate paint volume needed
We divide the paint area by the coverage rate for trim paint. Trim paint typically covers 350-400 sq ft per gallon, which is less than wall paint due to its thicker formulation:
Paint Needed (gallons) = Paint Area ÷ 375 sq ft per gallon
Step 5: Add extra paint for touch-ups and waste
We recommend adding a percentage of extra paint to account for touch-ups, waste, and uneven surfaces:
Total Paint = Paint Needed × (1 + Extra Paint Percentage ÷ 100)
Step 6: Calculate the estimated cost
Finally, we multiply the total paint amount by the price per gallon:
Estimated Cost = Total Paint × Price per Gallon
By using our baseboard paint calculator, you can be confident in your paint purchase decisions, saving both time and money on your trim painting projects.
