How Much Paint To Paint A House Interior

The amount of paint needed to paint a house’s interior completely depends on how large the size of the house is and the coverage rate of the paint to be used. Generally, a gallon of paint can cover 450 sq. ft. But to be safe, plan for 400 sq. ft. per gallon. Given this number, you can calculate how much paint you will need to paint the interior of your house, thus: Surface Area / Coverage Rate. You can multiply the result by the number of coats needed to give you how many gallons of paint to purchase.

For an average Australian home that measures around 2,300+ sq. ft, you will need almost 6 gallons (rounded off from 5.75 gallons) of paint. Houses in Hobart and surrounds average around 1.940+ sq. ft. That means you’ll need around 5 gallons (rounded off from 4.85 gallons) of paint. Rounding off the amount of paint you will need gives you an extra paint left just in case you will need it for retouching and finishes.

Painting Cost

The cost of a house interior painting job can range from $3,000 to $10,000. Usually, low-end prices have minimal prep work and use one paint colour while high-end prices have thorough prep work, and use multiple colours, and additional finishes. Below are some factors that can contribute to how much paint you will need for your interior house painting job.

Size. As mentioned, size matters. Large houses will definitely require large amounts of paint.

Property Condition. You need to consider how old the house is, its surfaces, and whether it’s been painted before (and how many times has it been painted), etc.

Type of Paint. There are price differences among types of paint you have to consider when painting the house interior in consideration of its current condition. For newly built structures, there’s acrylic or latex, gloss, matte, etc. For old structures, breathable paints are recommended.

Architecture & Design. The more intricate the architecture and design, the more paint is needed to achieve an outstanding finish.

Areas to be Painted. Speaking of design, some parts of the house, number of rooms, bathrooms, kitchen, etc. impact the amount of paint needed for interior painting.
