KurtHeckman.Room - Wall Paint

The **Paint for a Room** calculator estimates the number of gallons of paint or primer needed to cover a rectangular room (blue in diagram) based on the length, width and height of the room.

**INSTRUCTIONS:** Choose your preferred units and enter the following:

- (
**l**) Length of the room - (
**w**) Width of the room - (
**h**) Height of the room - (
**pP**) Choose paint or primer

**Total Volume: **The calculator computes the number of gallons of paint or primer needed for the room in gallons. However, this can be automatically converted into other volume units via the pull-down menu.

**Notes:** This formula will round up on the number of gallons used for pricing if the fraction part of the number of gallons is greater than 10%. Also, this does not include the ceiling. Often ceilings are painted with different paint since they tend to have less contact with people and other things, and because ceilings make for nice accent (lighter) surfaces.
