Selecting the correct toy size is crucial for both the profitability of your toy crane machine and player satisfaction. The primary rule is that the toy must be graspable by the claw. Generally, toys should be between 2.5 to 5 inches in their smallest dimension to fit securely in the claw's grip. They must also fit comfortably within the prize chute; a good test is to ensure the toy can fall through the delivery hole without getting stuck.

For capsule machines, the toy must obviously fit inside the designated capsule. Consider the toy's material as well. Soft, plush toys are easier for claws to grab than hard, smooth-surfaced items. The weight matters too. Excessively heavy toys can strain the machine's mechanism and are difficult to lift, while very light ones may slip from the claw too easily.

Always consult your machine's manual for its specific size and weight capacity limits. A well-chosen mix of correctly sized toys ensures fair play, maintains machine integrity, and keeps players coming back for more fun.
