Capsule sizes run from the large size 000<\/strong> down to the tiny size 5<\/strong>, and the numbers are not intuitive: the bigger the number, the smaller the capsule. This chart shows the volume, approximate length and how much powder each size typically holds, so you can pick the right one for your product.<\/p>\n\n

In short<\/strong>

Size 0<\/strong> and size 1<\/strong> are the most common sizes for supplements and medicines. Size 00 suits larger doses, size 000 is rarely used for oral products, and sizes 3 to 5 suit small doses or capsules for children and pets.<\/p><\/div>\n\n

Values are typical industry figures and vary slightly between manufacturers. “Elongated” versions such as 00el and 0el hold a little more than the standard size.<\/p>\n\n

How to work out the fill weight for your powder<\/h2>\n

The weight a capsule holds depends on how dense your powder is. Multiply the capsule volume by the powder’s tapped density:<\/p>\n

Fill weight (mg) = Capsule volume (ml) \u00d7 Powder density (g\/ml) \u00d7 1000<\/p>\n

For example, a size 0 capsule (0.68 ml) filled with a powder of 0.6 g\/ml holds about 0.68 \u00d7 0.6 \u00d7 1000 \u2248 408 mg<\/strong>. The same capsule filled with a denser powder of 1.0 g\/ml holds about 680 mg<\/strong>. Light, fluffy herbal powders need a bigger size than dense mineral powders for the same dose.<\/p>\n\n

Which size should you choose?<\/h2>\n
\n

Size 00 and 0<\/h3>

Larger single doses of herbal extracts, protein-type supplements and multi-ingredient formulas. Size 0 is the best-selling size worldwide.<\/p><\/div>\n

Size 1 and 2<\/h3>

Standard medicines and supplements with moderate doses. They are easier to swallow and popular for daily-use products.<\/p><\/div>\n

Size 3, 4 and 5<\/h3>

Small, potent doses, clinical trial blinding, and products for children or animals where a small capsule is easier to give.<\/p><\/div>\n<\/div>\n\n
