Accurately estimating exterior wall surface area is essential for budgeting exterior painting projects. Unlike interiors, external elevations may include multiple levels, irregular shapes, and varying surface materials.
Start by measuring the width and height of each elevation. Multiply width by height to obtain the surface area for that elevation. Repeat for each visible side of the property and add the totals together.
Large openings such as garage doors, patio doors, or large windows can be subtracted for a tighter estimate. Smaller windows can be left within the total because cutting in and detailing still consume labour time.
When measuring exterior walls, remember to account for features such as dormers, extensions, or projecting bays. These often increase surface area beyond what appears obvious at first glance.

Access planning is equally important. Even a modest two-storey property may require scaffolding depending on layout and ground conditions. Access costs should be considered separately when planning your budget.
