Introduction: Why Capsule Weight Matters
Have you ever asked yourself how many grams are in a capsule? No matter if you are a supplement maker, a fan of herbal medicine, or a pharmaceutical expert, knowing capsule weights is necessary for accurate and reliable dosing. The amount of powder held by capsules like 0 or 00 depends on how dense it is. We will look at how capsule size, powder density, and weight are connected, so you can pick the right capsule for your needs. Want to understand capsule weights and make your formulations more accurate? Let’s begin!
Capsule Sizes and Their Weight Capacities
The main thing to look at when figuring out how many grams are in a capsule is the capsule’s size. Capsules are available in different sizes, from the big size 000 to the tiny size 5. Most people choose 00, 0, or 1 as their usual capsule size for daily supplements and herbal mixtures because it is not too big or too small.
The trick is that capsule volumes are given in milliliters (mL), but to find out the weight in grams, you need to take into account how dense your powder is. As an illustration, a size 0 capsule contains about 0.68 mL. Low-density powders such as collagen will hold about 0.4g, but if you use something dense like activated charcoal, you can get up to 0.7g. Check out the chart below for a quick reference:
| Capsule Size | Volume (mL) | Approx Weight (Low-Density Powder) | Approx Weight (High-Density Powder) | Notes |
| 000 | 1.37 | ~0.82g | ~1.6g | Actual fill depends on powder density (0.6-1.2 g/mL typical range) |
| 00 | 0.95 | ~0.43g | ~0.95g | Range covers most herbal powders to dense materials |
| 0 | 0.68 | ~0.30g | ~0.68g | Common size for dietary supplements |
| 1 | 0.5 | ~0.22g | ~0.50g | Often used for low-dose actives |
| 2 | 0.37 | ~0.16g | ~0.37g | Smaller capsule, easier to swallow |
| 3 | 0.3 | ~0.13g | ~0.30g | For small amounts or children’s doses |
| 4 | 0.21 | ~0.09g | ~0.21g | Very small capacity |
| 5 | 0.13 | ~0.06g | ~0.13g | Extremely small; for specialty uses |

Understanding Density: Why Not All Powders Weigh the Same
We need to admit that some powders are better than others. Even if you have an empty capsule size 0, the amount of grams of powder in it will vary a lot based on the density of your powder. Density means the amount of mass (grams) in a certain volume (milliliters). This is the reason why collagen powder takes up more space in a capsule than vitamin C crystals or activated charcoal. For instance, when you fill empty capsules size 0 with vitamin C powder, each capsule could weigh about 0.5g since vitamin C is a dense substance. On the other hand, some fluffy herbal blends can only fill up to 0.3g in the same size 0 capsule. What is the secret? The formula is very straightforward: Volume × Density = Weight. If your powder has a bulk density of 0.7 g/mL and you’re using a 0.68 mL capsule, you should expect about 0.47g in each capsule. It becomes very useful when you get used to it.
How to Calculate the Weight of Your Capsule Fills
It’s time to have some fun by filling the capsules. You may be asking yourself, “How can I determine the weight of my capsules in real life?” It’s not as hard as it may seem, and it will work with either a manual capsule filler or by hand. First, weigh your powder on a small kitchen scale and use a known volume container to find out how many grams are in one mL. After that, find the size of capsule you need in a chart (like the one above) to discover its volume in mL and help ensure you choose the right size of capsule.
As an example, you could use a size 0 capsule that contains 0.68 mL, and your powder’s density is 0.8 g/mL. The math shows that each capsule contains 0.54 grams. If you want 1 gram per capsule, you should use a capsule that is 00 or even 000. That’s all there is to it! In this way, you can be sure your DIY supplement is accurate, with no extra powder or capsules that are too big. Win-win!
Choosing the Right Capsule Size for Your Needs
The big question is: what size capsule should you use? We can look at how people use it. If you are making herbal blends from ashwagandha or turmeric, choose size 00 or 000 capsules. The larger capsules include more powder, so you need fewer capsules and save time. When taking daily vitamins or minerals, size 0 or 1 is the best choice since they are easy to swallow and hold the right amount of active ingredients. If you are making capsules for children, elderly people, or those who find big pills difficult, you may prefer to use smaller capsules. Sizes 3 and 4 are ideal for giving small and gentle dosage. Even though you have to take more capsules, it’s better to be safe than sorry. All in all, there isn’t a universal solution, but these tips will help you choose the right size quickly.
Common Questions
How many grams in a size 0 capsule? A size 0 capsule holds about 0.4–0.7 grams depending on the powder’s density.
Which capsule size holds 1 gram of powder? To hold 1 gram of powder, you usually need a size 00 or 000 capsule to hold 1 gram of powder, as smaller sizes like 0 and 1 are not big enough.
What is the largest capsule size available? The biggest standard capsule size is 000, which is ideal for large herbal mixtures or or high-dose supplements.
How many capsules do I need for 5 grams of supplement? Depends on your capsule size and powder density! But for a powder density of 0.7 g/mL and size 0 capsules (~0.5g each), you’ll need around 10 capsules.
How accurate are capsule weights? It is accurate if you have the information about the powder density and the capsule volume. Never forget to weigh your filled capsules to be sure they are correct.
Capsule Fill Tips
If you make small amounts of products at home, a kitchen scale and a set of micro-scoops will be very useful. Use a manual filler to get clean and even fills with less mess.
For large-scale production, having capsule filling machines is very beneficial. High-speed capsule fillers are able to precisely and quickly fill capsules of different sizes and densities with the right amount of powder. They help cut down on waste, increase how well the factory operates, and fulfill the strict quality standards for dietary supplements and pharmaceuticals.
