A choke tester can be used to check the size of objects offered for children under 3 years. This is a cylinder that is 2.25 inches long by 1.25 inches wide (5.7 cm long by 3.2 cm wide), about the width of two fingers. A toilet paper tube can also be used to check for safety. If it can fit in the toilet paper roll, it is probably a choking hazard.
