How much paint to buy?

We’re painting the entirety of our home’s interior in white as we prepare to sell it. The home is 3 bedrooms, 2 bathroom and approximately 1800 sq. ft. with 8 foot ceilings

Is there a way to approximate how much paint we need without taking the measurements of each room?

Your best bet is to measure. It is certainly worth your time.

That being said our numbers reflect roughly 20 gallons for a home that size.

Remember, this is a guess, not a quote!

Good luck.

Sherwin Williams has a great paint calculator that will help determine how much paint will be needed. Unfortunately, you will need to get basic measurements of the rooms, but the calculator will help you with the quantity of paint needed. Here is the link to the calculator.

Yes, are you changing colors or will you need two coats?
