The DIY Paint Calculator provides an accurate calculation of how much paint it takes to paint a room by taking input from the user for dimensions of the walls to be painted, as well as subtracting the area for windows and doors from the total square footage. The DIY Paint Calculator also calculates the area for walls with a vaulted ceiling. On the calculation page, the DIY Paint Calculator gives the user the ability to put in an exact coverage for a specific paint brand and alerts the user that this application calculates the amount of paint for one coat of paint. Users are able to save, load, and delete their paint calculations.
