How Many Gallons of Paint to Paint an Exterior House

Introduction

Grasping the Complexity of Paint Quantity Estimation

Determining the right amount of paint needed for your home’s exterior can often feel overwhelming due to the various factors at play. Start by measuring the total square footage of the surfaces to be painted, including walls, trim, and any architectural features like eaves or overhangs.

For a standard calculation, multiply the height by the width of each wall section, and don’t forget to subtract areas for windows and doors, which typically account for about 15-20% of the total wall area. Next, consider the type of surface you are painting; different materials, such as wood, stucco, or brick, have varying absorption rates.

For instance, porous surfaces like unpainted wood may require more paint compared to smoother surfaces like vinyl siding. Additionally, the paint’s coverage rate, usually indicated on the can, will guide you on how many square feet a gallon will cover. A common coverage rate is around 350-400 square feet per gallon for a single coat.

However, if you’re applying a darker color over a lighter one, or if the surface is particularly textured, you may need to factor in an extra coat. By carefully measuring and considering these elements, you can make a more informed estimate, avoiding the common pitfalls of overbuying or underestimating your paint needs.

What Factors Influence Paint Quantity?
