Calculate the surface area of your house's exterior by measuring the height and width of each side and summing them up. Subtract areas like windows and doors. One litre of paint typically covers about 10-12 square meters. For example, if your house's total paintable area is 200 square meters, you would need approximately 17-20 litres of paint. Always buy a bit extra to account for second coats or touch-ups.
