Before starting any renovation project, it is essential to know how much paint you need to buy so that you don’t waste your time, money, and resources and can avoid making multiple trips to the store. A paint calculator can help you determine the exact amount of paint required for a specific project.
Graana.com has compiled everything you need to know about a paint calculator, including how it works on walls and ceilings.
To use a paint calculator, you will need to know some details about your painting project, such as the size of the room, the number of coats you plan to apply, and the type of paint you are using. The paint calculator will then calculate the amount of paint you need based on these factors.
One gallon of paint can cover an area of 350 square feet. If you need to apply two coats, you will, of course, require twice the amount of paint.
Additionally, it is important to consider applying a primer coat before the paint to ensure the surface is sealed correctly and won’t absorb the colour.
Follow the steps below when using a paint calculator:
To accurately estimate the amount of paint required for your walls, start by measuring the room. Calculate the square footage of the room by adding the length of each wall and multiplying it by the height of the room from the ceiling to the floor.
However, when calculating the paintable surface, make sure to subtract the area of windows and doors from your measurement. One gallon of paint typically covers 350 sq ft. To determine the number of gallons you need, divide the total square footage of the paintable wall surface by 350.
For example, if the room is 11 x 15 ft, and has one window and two doors, the total size of the paintable surface would be 416 sq ft (468 sq ft total wall area minus the area of windows and doors). So, you would need 1.18 gallons of paint (416 sq ft ÷ 350).
If the result is a fraction, round up or order extra paint in quarter cans. If you plan on applying a double coat, double the amount of paint needed.
Calculating the amount of paint you need for your ceiling is a straightforward process. First, determine the square footage of your ceiling by multiplying its width by its length.
For example, a ceiling with dimensions 11 x 15 feet would have a square footage of 165 sq ft. Divide this number by 350 to determine the number of gallons of paint needed. In this example, you would need 2 quarts of paint, but if you plan to apply a second coat, consider purchasing 1 gallon instead.
To calculate the paint area for doors and windows, follow the steps below:
It’s also helpful to choose a high-quality paint brand and familiarise yourself with the different interior paint finishes available.
In conclusion, a paint calculator can be a useful tool for any painting project. Just remember to measure the area, determine the number of coats, and choose the right paint to get the best results.
