Capsule Size Chart

To understand capsule size chart is somewhat substantial for professionals and individuals. Selecting a proper capsule according to your need takes a lot of time and research, hence the capsule size chart will save your time and energy. Many consumers are unfamiliar with industrial standards for selecting a correct capsule size that results in purchasing wrong-sized capsules ultimately poor production output.

Whether you are a professional or hobbyist, the capsule size chart and explanation on this page can be exceptionally helpful to you.

Basic Dimensions of a Capsule are?

To understand the basic dimensions of the capsule is very important to assess the capsule sizes. No matter what type of capsule you use, either gelatin, vegetarian, or HPMC, their structure is almost similar in all instances.

An overall closed length involved size of the capsule includes a closed shell with the formulation. A cap length is the shortest region of the capsule that is the best fit to the top of the body once a capsule is filled with formulation content. Whereas the body is the long end of the capsule that holds the formulation inside.

Capsule-2

Weight capacity ensures the concentration of formulation that can perfectly fit into the body of the capsule. Weight capacity depends upon the density of the formulation substances. You won’t be able to significantly fit lighter substances into desired capsules as you would do with a greater density even the same ingredients are produced by two different manufacturers.

Discussed below are the basic points of capsule dimension that will help you to understand the capsule size chart easily.

Capsule Weight

Capsule Weight

An empty capsule weight is known as capsule weight.

Volume Capacity

Volume Capacity

The inside volume of the capsule is known as volume capacity, expressed in milliliters.

Weight Capacity

Weight Capacity

The weight capacity of the capsule depends upon the density of formulation, expressed in milligrams.

Overall Length

Overall Length

It is measured as the length of the capsule when closed entirely and locked. It is expressed in millimeters.

Individual Length

Individual Length

When you measure the length of the capsule such as the cap and the body individually. It is known as the individual length of the capsule.

Tolerance

Tolerance

It is the acceptable deviation in dimensions.

The Standard Sizes of a Capsule are?

 

standard capsule size

Many different capsule sizes around you make it difficult to figure out the correct capsule size according to your need. For many applications commonly used capsule sizes range from 00 to 0 which is often known as a standard size of the capsule.

These are considered as common sizes because they contain a usual dose for therapeutic medications. Such as:

  • ‘00’ has the affinity to hold 735 milligrams or 0.735grams while
  • ‘0’ has an affinity to cover 500 milligrams or 0.5 grams of powdered ingredients.

Furthermore, you can classify capsule sizes into three main parts:

Large Capsule

Large Capsule

A size ‘000’ is known as the largest capsule size that has the capacity to hold nearly 1000mg or 1 gram. But this weight is dependent upon the density of the ingredient. Therefore, it is recommended to assess the mesh size and density of filling powders from the capsule size chart below in this blog.

Average Size Capsule

Average Size Capsule

A size ‘00’ is known as an average size capsule that has an affinity to hold material 750 mg, while the volume of the capsule is 0.68ml. Due to size and great filling capacity, most of the nutraceutical or supplement industry prefer these capsules.

Size-0 capsule

A size ‘0’ has an affinity to hold a dose of 500 mg which is an average dose size. This is the most applied form of capsule which is implemented for pharmaceutical and beauty industries. The volume of the capsule for ‘0’ is 0.68ml.

Small Capsules

Size-1 capsule

Some people might face trouble with swallowing large or average capsules. For this small capsule is preferred that is of size ‘1’ holds about 400 milligrams. Size ‘1’ capsule has the capacity to hold 0.5 ml of volume which is indeed not the best fit for those who want a high dosage formulation.

Size-2 capsule

Furthermore, size ‘2’ is a small capsule class, that can hold about 300 milligrams filling ingredients preferably used for those consumers who have problems with swallowing the large capsule.
Mostly small capsules require an intricate and complex filling procedure, that is why these are not popular among consumers as a buying choice. But, due to lower-cost material, they are available as the cheapest form of capsules.

Whether you are a manufacturer or hobbyist and want you to encapsulate your own formulation. Choosing a capsule with the best fit size will make a better difference and enhance the product quality. Today’s market has plenty of various capsule sizes supplemented by competitive manufacturers.

Discussing the following points will enable you to select the correct size of the capsule through a size chart.

For easy understanding see below the illustration. Here, you can find ‘millimeters’ on the left side while ‘inches’ on the right side.

How do you determine formulation density & mass?

For encapsulation, you must consider two primary things: formulation density and mass.

Formulation density is determined by the following formula:

Density= Mass/Volume

Density is expressed in gram/ml, while mass is given in gram, and volume is given in ml.

Mass is simply assessed by weighing the weight of the product using an accurate scale.

Volume is the concentration of substance enclosed within a capsule.

In simpler words, if you want to encapsulate 600mg of substance, you need to place 600mg into a measuring spoon and determine its volume you need to fill their volume till demarcation. For instance, demarcation is 1ml. So, divide 600mg/1ml that will yield gm/ml. Thus, formulation density is 0.6 grams/ml.

The next step is to see the chart.

See the density closest to 600mg, in mentioned chart ‘00’ size is suitable to accommodate your requirement.

How do you find a suitable bottle volume and a capsule count?

It is important to match capsule size with bottle volume. By doing this, you can estimate the capsule count for each bottle or container.

A Guidance Chart for Capsule Count Per Bottle Size

1 30 60 90 120

The following chart has three main parameters

  • Capsule size
  • Bottle size
  • Capsule per bottle

According to the capsule size and bottle capacity, you can easily assess the number of capsules in each bottle. For instance, if you want to pack size ‘000’ capsules in a bottle. Through a guidance chart, you can assess capsule count, such as:

  • 30 capsules in 120 ml bottle
  • 60 capsules in 200 ml bottle
  • 90 capsules in 300 ml bottle
  • 120 capsules in 400 ml bottle
  • 180 capsules in 500 ml bottle

Conclusion

The exact aim of this blog is to make you capable to understand and learn the basic terminologies and techniques to determine the capsule size. We hope now you will be capable enough to decide the correct capsule size according to your formulation density. It’s time to begin scrutinizing and order the bulk empty capsules now.
