Interior Paint Calculator

Before installing your new window treatments, you'll want to make sure that
your room has a nice, fresh coat of paint.
This calculator will give you an estimate of the amount you'll need.

Remember that textured surfaces such as sand/popcorn ceilings and rough plaster walls will have more surface area and be more absorbent...expect to use more paint in those situations.
Also, two coats are really necessary,
don't skimp!
