Capsule size chart fill weight and capacity comparison

We get a lot of questions asking “what are the different capsule sizes?”, “how much powder does a certain size capsule hold and which one would I need to fill a certain amount of powder?” “what are capsule sizes?”, So here is capsule sizes explained in a simple guide and gelatin vegetarian capsule size chart.

What Capsule Size Is Right For You?

Because of all these different capsule sizes, we supply it might be hard to figure out which size is right for your needs. 

We have provided a more detailed infographic chart on the specifications on the different capsules we carry for both gelatin and vegetable. 

For most applications, a size 00 or size 0 will be sufficient and are often classed as standard capsule sizes.. They are the most common sizes used by all because a size 0 holds about 500mg or 0.5 grams of powder while a size 00 holds about 735 mg or 0.735 grams.

Large Capsule

Size 000 is the largest capsule size for human use, on average this holds about 1000mg, but that all depends on powder density. Because of this, it is best to check the powder you wish to fill mesh size and density. please check the capsule size chart below for more details

Average Size Capsules

00 capsule capacity holds about 750mg, because of the size and great fill weight it is one of the most common capsule sizes used in the supplement industry, the volume of the capsule is 0.93ml and capsule size 00 is 23.6mm big locked.


how much does a size 0 capsule hold? about 500mg, because of the great average dose size, it is one of the most common capsule sizes used in the pharmaceutical and beauty industry. the volume of the capsule is 0.68ml and capsule size 0 is 21.3mm locked length.

Capsule Size 0 vs 00? when considering which capsule to use, we would need to know what fill weight we want to achieve, and if we want to use any bulking agents, what capsule machine would be in use.

Small capsules

Size 1 holds about 400mg. and is a great size for those who have trouble with swallowing capsules but with only a 0.50ml volume fill density is not the best for consumers wanting high dosage.

Size 2 holds about 300mg. and again is a great size to use if you have trouble swallowing capsules,

because of the small size capsule makes this really hard to fill with powder and tricky to use. Because of this, makes it not a popular buying choice for consumers but one of the cheapest due to lower material costs.

Capsule Size and fill weight

The fill weight depends on the powder density and particle size. Some powders can be much denser than others. But it also depends on how fine the powder is. Because of this, a good way to check is to know the powders mesh size.

  1. I only need to put roughly 3 mg inside of a capsule, would a size 2 be my best bet ? It’s a time amount.
