Tray Sizes for 0, 1, and 2 Capsules: What Actually Fits
Why capsule size determines tray compatibility
Hard capsule sizes are not interchangeable in a filling tray because the body and cap diameters change from size to size. The tray works by holding the capsule body upright in a hole while you fill powder and then press the cap on. If the hole is too large, the capsule can tilt or fall through; if it is too small, the capsule will not seat. Sizes 0, 1, and 2 sit in a middle range of the hard capsule scale, but they still have distinct diameters. General educational guidance: treat any tray's stated size support as the only reliable compatibility signal. Verified fact for the example product: the 14-Hole Capsule Filling Tray for Sizes 0, 1/2 & 5 lists sizes 0, 1/2, and 5 in its title and product data. It does not list standard size 1 or size 2, so you should not assume it will hold those capsules securely. The tool in this step is the 14-Hole Capsule Filling Tray for Sizes 0, 1/2 & 5.
Mapping your capsule size to the right tray
Use this decision rule: match the exact size printed on your empty capsule container to the exact size listed for the tray. For size 0, a tray that explicitly lists size 0 is compatible. For size 1, look for a tray that lists size 1; the example 14-hole tray lists 1/2, which is a different capsule size, so it is not the same as size 1. For size 2, look for a tray that lists size 2. If a product title mixes sizes with a slash or plus sign, read it literally rather than as a range. Verified example: the 14-Hole Capsule Filling Tray for Sizes 0, 1/2 & 5 is a 14-hole tray for sizes 0, 1/2, and 5. If your capsules are size 1 or size 2, that tray is not the correct match based on its stated sizes. A dedicated size 1 tray or size 2 tray is the safer choice. This builds on our earlier guide, How to Choose the Right Capsule Filling Tray for Your Capsule Size (00/0/1/2).
What the 14-hole format means for your workflow
Hole count is separate from size compatibility. A 14-hole tray holds 14 capsules per filling cycle, so it suits small batches and personal use rather than high-volume production. Verified fact: the example product has 14 holes. Assumption to state clearly: if you fill 14 capsules per cycle and complete a cycle in roughly 5 to 10 minutes by hand, that is about 84 to 168 capsules per hour, but actual time depends on your powder, your experience, and whether you use a spreading card. The 14-hole format does not change which capsule sizes fit; it only changes batch capacity. Do not buy a 14-hole tray expecting it to fit size 1 or size 2 capsules unless the product data lists those sizes. There is more on capsule tray compatibility in the same guide.
Limitations and what to check before buying
Product titles and listings can use shorthand that is easy to misread. A title like Sizes 0, 1/2 & 5 should be read as three discrete sizes, not as a range from 0 to 5. Verified fact: the example tray's listed capsule sizes are 0, 1/2, and 5. General guidance: before ordering any tray, confirm the size list, the hole count, and whether the tray is described as a filling tray with a compatible cap-holding section. The supplied product data for the example does not include material, dimensions, or certification details, so do not assume those. If you need size 1 or size 2 support and the listing does not name them, ask the seller to confirm in writing or choose a tray that names your exact size.
