Measure length times height for a wall's square feet. If the room has doorways or cabinets in the way, you can break the room's walls into easier to figure areas and then add up all the measurements to get the total square footage for an entire room. Refer to the paint can for the coverage of the paint and calculate how many cans you will need. Do not forget that only one coat of paint is calculated for. If you need two coats, you will of course need twice the amount of paint.

Many home improvement stores have websites and calculators for how much paint to purchase for your project and also if you plan on using a primer to base coat the wall.

See the related link for a calculator.
