In short: For whole-bean coffee, order a 13 × 21 + 4 cm stand-up pouch for 250 g, a 16 × 26 + 5 cm stand-up pouch or 11 × 32 + 7 cm side-gusset bag for 500 g, and a 13 × 38 + 8 cm side-gusset or 15 × 30 + 10 cm flat-bottom bag for 1 kg. Ground coffee packs 15–20% denser than whole beans, so the same weight fits one size smaller. Allow 3–4 cm of headspace above the fill line for the top seal.
Sizes are width × height + gusset for a 0.35–0.40 g/cm³ roast; confirm with a filled sample before mass production.
Coffee bag size chart by net weight
| Net weight (whole bean) | Stand-up pouch | Side-gusset bag | Flat-bottom bag |
|---|---|---|---|
| 250 g / 8 oz | 13 × 21 + 4 cm | 9 × 25 + 6 cm | 10 × 22 + 6 cm |
| 500 g / 1 lb | 16 × 26 + 5 cm | 11 × 32 + 7 cm | 12 × 26 + 8 cm |
| 1 kg / 2.2 lb | 20 × 30 + 6 cm | 13 × 38 + 8 cm | 15 × 30 + 10 cm |
| 2 kg / 5 lb | — | 16 × 45 + 10 cm | 18 × 36 + 12 cm |
Whole bean vs ground: adjust for density
- Whole beans: 0.35–0.40 g/cm³, so 250 g needs 650–700 cm³ of bag volume and 1 kg needs 2.6–2.9 L.
- Ground coffee: 0.42–0.48 g/cm³. 250 g ground fits a 12 × 20 + 3.5 cm stand-up pouch; 500 g ground fits 15 × 24 + 4.5 cm.
- Dark roasts are less dense than light roasts; if one bag serves both, size for the dark roast.
Which bag style fits which weight
Stand-up pouches: 250 g to 1 kg, largest print panel, the usual choice for retail and e-commerce packs. Side-gusset bags: 500 g to 2 kg café and wholesale supply, pack flat in cartons and take a tin tie. Flat-bottom bags: 1 kg specialty retail, more volume per shelf width; see stand-up pouch vs flat-bottom bag.
Material and thickness by bag size
- 250 g: PET / AL / PE or PET / VMPET / PE, 100–110 µm (0.10–0.11 mm).
- 500 g: PET / AL / PE, 110–120 µm; add a matte BOPP outer layer as on our matte stand-up pouches with valve.
- 1 kg: PET / AL / PE at 120–140 µm, or kraft / AL / PE at 130–150 µm. Below 120 µm a 1 kg bag creases at the gusset corners.
- 2 kg: 140–160 µm with a 12–18 mm bottom seal.
- Recyclable: mono-material PE / EVOH / PE, 120–140 µm, always with a one-way valve.
Chart heights already include the 1.5 cm a zipper or tin tie adds; the valve sits 2–3 cm below the top seal (see why coffee bags need a degassing valve). Zipper, tin tie and window options: coffee bags with valve and custom printed coffee bean bags.
FAQ
What size coffee bag holds 250 g of whole beans?
A 13 × 21 + 4 cm stand-up pouch or a 9 × 25 + 6 cm side-gusset bag holds 250 g of roasted whole beans with 3–4 cm of headspace.
What size coffee bag holds 1 kg?
A 13 × 38 + 8 cm side-gusset bag or a 15 × 30 + 10 cm flat-bottom bag holds 1 kg of whole beans; use 120–140 µm film so the gusset corners do not crease.
Can I use the same bag size for whole bean and ground coffee?
Yes, if the bag is sized for whole beans; ground coffee is 15–20% denser and sits lower in the bag.
How thick should a 500 g coffee bag be?
A 500 g coffee bag is normally 110–120 µm (0.11–0.12 mm) in a PET / AL / PE or PET / VMPET / PE structure.
