Capsule Size Chart

Our online calculator will allow you to choose the right capsule size based on your unique ingredient type and quantity.

Find out which capsule size suits your needs!

The gelatin and vegetarian empty capsules are named by numerical values: 000, *00E, 00, *0E, 0, 1, 2, 3, 4 and 5. For your reference, the largest capsule is 000. Most of the capsule filling machinery are manufactured to be compatible with these standard sizes.

*00E and 0E are elongated capsules.

Check the size chart below to find put which capsule suits your need.

How to read Capsuline’s Empty Capsule Size Chart

  • Capsule Weight - The total weight of the capsule, measured in milligrams (mg).
  • Volume Capacity - The total volume of the inside of the capsule in milliliters (ml) - Note 1 milliliter(ml) = 1 gram(g).
  • Weight Capacity by Formulation - The total weight capacity of the capsule measured in milligrams(mg) depending on the density of your formulation.
  • Overall Closed Length - The total length of the capsule when it is fully closed and locked.
  • Individual Lengths - Measures both the body and the cap of the capsule’s in both millimeters and inches. The Body is the longer part of the capsule that is filled with your material. The Cap is shorter than the body and is placed over the body to form a complete capsule.
  • External Diameter - The total diameter of both the body and the cap.
  • Tolerance - The allowable variance in dimensions that is allowed prior to a product being considered flawed and/or unfit for sale.
