Measured mode uses length × width × average height in feet ÷ 27 to estimate cubic yards. For light material, it shows the smallest listed nominal size at or above that estimate. For example, a 12 × 9 × 3 foot loose pile is 12 cubic yards, so the first size to compare is 15 yards. The calculation adds no packing allowance. Furniture, irregular shapes, gaps, and an uneven pile can change the space needed. A measurement close to a size limit is a reason to compare the next size with the provider. Rough project mode uses a fixed project-and-amount lookup rather than a measurement or weight calculation. It is a starting comparison, not a promise that a room, roof, or project fits a particular container. When should I ask for a load review? Roofing, tile, concrete, dirt, brick, rock, and uncertain mixed loads need a provider-approved weight and fill plan. This tool does not estimate debris density, safe payload, included tonnage, price, or availability. It sends those projects to a review without choosing a size.
