What size flat bottom pouch do I need for coffee?
The following ranges are practical starting points for whole roasted coffee beans. They are not universal standards. Bean origin, roast degree, zipper position, seal width and the way the pouch is constructed can all change the result.
| Coffee fill weight | Approximate product volume | Typical flat bottom pouch size range* |
|---|
| 250 g / 8.8 oz | 0.6–0.8 L | 120–140 mm W × 200–230 mm H × 70–90 mm D |
| 500 g / 17.6 oz | 1.2–1.6 L | 130–160 mm W × 250–290 mm H × 80–100 mm D |
| 1 kg / 35.3 oz | 2.4–3.2 L | 150–190 mm W × 300–360 mm H × 90–120 mm D |
*These dimensions describe a broad market range, not a production specification. The depth may be written differently by different pouch suppliers.
Published stock-bag dimensions show the same variation. One supplier lists approximately 120 × 190 × 74 mm for 250 g, 130 × 265 × 84 mm for 500 g and 130 × 335 × 104 mm for 1 kg flat bottom coffee bags (A47 Coffee size reference). Other suppliers use wider or shorter formats for the same nominal capacity. That does not make one size wrong. It shows why nominal coffee weight should not replace a filling test.
The approximate product volume in the table describes the space occupied by the beans before extra operating room is added. The pouch itself normally needs more usable capacity for filling, settling, closing the zipper and making the top seal. Freshly roasted beans also release carbon dioxide after roasting, so a coffee pouch should not be packed solid to the top.
Ground coffee may use a smaller bag than whole beans at the same weight because it usually packs more densely. Do not reduce the dimensions automatically, though. Grind size, roast level and the filling machine can change the result. Test ground coffee separately.
The proportions also affect the finished appearance. A tall, narrow pouch can look compact and works well when shelf width is limited. A wider pouch provides a larger front panel and may stand more firmly, but it takes up more horizontal space. Both can hold a similar volume if the height and depth are adjusted.
