Capsule sizes can seem counterintuitive as smaller sized capsules have higher numbers than larger capsules. e.g. a # 5 capsule is smaller than a #4 capsule A "000" (triple zero) capsule is the largest size available. In cases where capsule sizes are indicated with "0" names, 000s are the largest, while 0s are smaller.
The most popular capsule is size 00 and size 0. Below is a scale of size 0 and 00 capsules next to common coins to show their size.
