Getting accurate material estimates
Material estimates start with good measurements. Measure each dimension at its longest and widest points, note the height of walls or the depth of a bed, and account for doors, windows, and obstacles. Small errors compound across a large surface, so it is worth measuring twice.
Coverage figures vary by product. Paint spread, bag yields, and package coverage differ between brands and even between colors, so use the numbers printed on what you are actually buying. Each EasyBuildTools calculator lets you enter these values directly rather than assuming a single fixed figure.
Finally, plan for waste. Cuts, breakage, and uneven surfaces mean you rarely use exactly the calculated amount. A modest allowance — often 5 to 15% — keeps you from running short at an awkward moment. For structural work, treat the figures as a starting point and confirm with local building codes.
