The smallest standard trash can from our trash can factory is typically a 3-liter mini desk or bathroom bin, equivalent to about 0.8 US gallons. Its standard round-body dimensions are approximately 15.5 cm (6.1 in) in top diameter, 12.5 cm (4.9 in) in base diameter, and 24.5 cm (9.6 in) in height. The opening diameter is usually around 12 cm (4.7 in). For a rectangular 3L model, a common factory specification is about 20 cm × 14 cm × 25 cm (7.9 in × 5.5 in × 9.8 in). These measurements refer to the finished product and may vary slightly by lid style, pedal design, material thickness, and packaging requirements. If you need a smaller custom mini trash can, we can review mold availability and minimum order quantity to produce options such as 1.5L or 2L models. For accurate ordering, always confirm the final capacity, outer dimensions, inner dimensions, and carton size with our sales team before placing a bulk order.
