Bagasse Sushi Tray Sizes Explained: No.3 to No.9 and ST-3G to ST-5G
Jirun's numbered bagasse sushi trays come in 4 sizes. The number is a size code: No.3 is 165 × 115 × 25 mm and 10 g; No.5 is 185 × 129 × 23.6 mm and 12 g; No.7 is 222 × 139 × 23.6 mm and 15 g; No.9 is 241 × 151 × 23.6 mm and 18 g. Each step up adds 19–37 mm of length, while the height stays at 23.6–25 mm. A second series, ST-3G, ST-4G and ST-5G, is 22 mm high; its codes do not follow size. Choose the size by measuring your roll set, not by the number.

Footprint is length × width of the outer rectangle; the usable flat area inside the rim is smaller. ST-G sizes and cartons are from the factory's specification table.
What changes from one size to the next
| No.3 → No.5 | +20 mm length · +14 mm width · +49 cm² |
|---|---|
| No.5 → No.7 | +37 mm length · +10 mm width · +70 cm² |
| No.7 → No.9 | +19 mm length · +12 mm width · +55 cm² |
Height is 23.6 or 25 mm across the numbered series, so a larger number means a larger footprint, not a deeper tray.
Choose from your roll set, not from the number
1. Lay out the set as it will be sold, including garnish, ginger and sauce sachets.
2. Measure its length and width and add a margin on each side for the rim.
3. Pick the smallest tray whose length and width both exceed that, then order samples of that size and the next one.
Tray numbers are not standardised across manufacturers: a "No.5" from another supplier may have different dimensions. Always compare millimetres.
Cartons and container loading by size
Larger trays mean fewer pieces per container. The fluorine-free grade uses a wax-emulsion grease barrier with no fluorochemicals added and is rated by the factory for oil up to 50 °C (low-temperature version) or 70 °C (high-temperature version); these are factory data, not yet confirmed by a third-party test.

Questions buyers ask
What size is a No.5 bagasse sushi tray?
185 × 129 × 23.6 mm and 12 g in Jirun's catalogue, model JR-S02. That is a footprint of about 239 cm². Tray numbers are not standardised between manufacturers, so check the millimetres on any supplier's sheet.
How much bigger is each sushi tray size than the one before?
No.5 is 20 mm longer and 14 mm wider than No.3, about 49 cm² more footprint; No.7 is 37 mm longer and 10 mm wider than No.5, about 70 cm² more footprint; No.9 is 19 mm longer and 12 mm wider than No.7, about 55 cm² more footprint.
How deep are bagasse sushi trays?
No.3 is 25 mm high, No.5 is 23.6 mm high, No.7 is 23.6 mm high, No.9 is 23.6 mm high. The trays are shallow bases; total pack height depends on the lid.
How many pieces of sushi fit on each tray size?
As a guide from the factory: No.3 holds 3–4 pieces of nigiri or 2 rolls; No.5 holds 5–6 pieces of nigiri or 2–3 rolls; No.7 holds 7–8 pieces of nigiri or 3–4 rolls; No.9 holds 9–10 pieces of nigiri or 4–5 rolls. Roll diameter and garnish change this, so confirm with samples of two adjacent sizes.
