Capsule Size Guide
Capsule sizes are labeled with a numerical value, with higher numbers indicating the smallest capsule size and the smaller number indicating the larger size. In cases where capsule sizes are indicated with “0” names, the 000s are the largest, while the 0s are the smaller. So majorly there are 8 different capsule sizes #000, #00, #0, #1, #2, #3, #4 & #5 sizes. These sizes are available in hard gelatin as well as vegetarian capsules.
Fill weight is each capsule depends upon available volume inside and bulk density of product to be filled. We are giving here below diametrical information of different capsule sizes:
