If you are wondering what size capsule you should purchase for your desired supplement dosage, you are not alone. It is a very common question asked by people filling their own capsules, because no one wants to purchase the wrong size and have to return them. So how do you know if you need to buy the size 000, 00, 0, 1, 2, 3, or 4 pill capsules? Here is an easy to read empty capsule sizing guide to help you choose the size that is right for you.
Overall Closed Length measures how long each sized capsule is when it has been completely closed shut with the powder inside.
The Cap is the shorter part of the capsules that is placed over the body when it has already been filled.
The Body is the longer end of the capsule that is placed inside the capsule filling machine holes and filled with the powder.
|Size||Closed (in)||Cap Dimensions (in)||Body Dimensions (in)|
|Tol.||± 0.012||± 0.014||---||± 0.014||---|
Capsule Volume measures the available filling capacity of the capsule, in milliliters (ml).
Capsule Weight is the weight of the empty capsule, measured in milligrams (mg). Vegetarian capsules are slightly heavier than gelatin.
|Size||Volume (ml)||Weight (mg)||Weight (mg)|
|Size||Capacity||Gel. Capsule||Veg. Capsule|
|000||1.37||158 ± 10||163 ± 10|
|00||0.95||123 ± 7||136 ± 7|
|0||0.68||99 ± 6||105 ± 6|
|1||0.48||76 ± 5||79 ± 5|
|2||0.36||61 ± 4||63 ± 4|
|3||0.27||48 ± 3||50 ± 3|
|4||0.20||38 ± 3||40 ± 3|
Weight Capacity measures how much of your desired powder you can fit inside each capsule. This depends largely on the density (measured by grams per milliliter) of the powder, which vary widely. "Fluffy" or "Light" powders with a low density (around 0.6 g/ml), can’t fit as much into a capsule as a powder with a high density (around 1.2 g/ml).
|Weight Capacity by Powder Density|
|Size||Capacity (mg)||Capacity (mg)||Capacity (mg)||Capacity (mg)|
|Size||@ 0.6 g/ml||@ 0.8 g/ml||@ 1.0 g/ml||@ 1.2 g/ml|
