The capacity of a fully stocked toy crane machine varies significantly based on its size and the type of prizes inside. A standard, mid-sized arcade claw machine typically holds between 50 to 100 plush toys or small prizes when optimally packed. Larger, deluxe models can accommodate 150 items or more, while smaller countertop versions may only hold 20-30.

The exact number depends on several factors. The size of the prizes is the primary determinant; smaller plush toys or capsule toys allow for a higher count. The skill of the operator in strategically stacking and arranging prizes also maximizes space. Machines are designed to look abundantly full to attract players, so operators aim to create a dense, tempting pile. Common setups involve a base layer of prizes filling the entire floor, with additional layers built up, especially around the drop chute. Therefore, while there's no single universal number, a range of 50-100 prizes is a reliable industry standard for a fully loaded, standard-sized machine ready for play.
