Coffee Bag Sizes Guide: 8oz, 12oz, 16oz & 1kg Compared

Eight ounces or a kilo? The size you choose changes the bag style, the film consumption, the case count — and how your brand looks on the shelf. Here are the four sizes we manufacture most, with real dimensions.

01The four standard retail sizes

Dimensions vary with bean density and roast level — dark roast is less dense and needs more volume. We confirm final dimensions against your actual beans before plate-making.

Nominal SizeWhole Bean FillFlat Bottom Bag (W×G×H)Best For
8 oz / 250 g227–250 g110 × 70 × 260 mmSample packs, premium microlots
12 oz / 340 g340 g120 × 80 × 290 mmUS specialty retail standard

02Size drives bag style

Under 500 g, both stand-up pouches and flat bottom bags work well; flat bottom wins on shelf presence. At 1 kg and above, flat bottom (box pouch) or side-gusset bags are the practical choice — a filled 1 kg stand-up pouch slumps and tips on the shelf.

03A note on custom sizes

Non-standard fill weights are normal in private label. Because we convert bags in-house, a custom dimension adds no lead time — only a one-time die adjustment. Low MOQ applies to custom sizes too.

Key Takeaway

Pick the size your customer buys, not the size that is cheapest to make — then let the factory match bag style and dimensions to that fill weight. The four sizes above cover 90% of retail coffee programs.
