In short: For nuts, trail mix and granola, the standard stand-up pouch sizes are 10 x 15 + 3 cm for 100 g, 13 x 20 + 4 cm for 250 g, 16 x 24 + 4 cm for 500 g and 20 x 30 + 5 cm for 1 kg (width x height + bottom gusset). Chips, popcorn and puffed snacks need one or two sizes larger because their bulk density is three to five times lower.
Stand-Up Pouch Sizes by Fill Weight
Bulk density assumed: 0.5–0.65 g/ml (nuts, trail mix, granola clusters, gummies, hard candy). Allow 20–25% spare capacity for the zipper and top seal.

Material and Thickness for Each Size
Choose the laminate by shelf life (OTR and WVTR figures: barrier properties guide), then thickness by pouch size.
- Clear PET/PE, 100–110 µm: dried fruit, candy and nuts up to 250 g sold within 4–6 months.
- PET/VMPET/PE, 110–130 µm: granola, trail mix and roasted nuts up to 500 g, 9–12 months shelf life.
- PET/AL/PE, 130–150 µm: 500 g to 1 kg oily nuts and seeds needing 12–18 months. See the aluminum foil stand-up pouch.
- Kraft/VMPET/PE, 120–140 µm: natural-look brands; a clear window up to 40% of the front panel is possible on a kraft paper stand-up pouch.
Zipper, Notch and Hang Hole Specifications
Press-to-close zipper 25–30 mm below the top seal up to 500 g; heavy-duty zipper with 10 mm top seal at 1 kg. Add tear notches above the zipper, R 5 mm round corners on retail sizes, and a 6 mm round or euro hang hole on peg-displayed pouches of 250 g and under.
Common Snack Pouch Sizes to Specify
- 10 x 15 + 3 cm, 100–110 µm, metallised, 100 g nuts, 50 g dried fruit
- 13 x 20 + 4 cm, 110–120 µm, metallised or foil, 250 g nuts or trail mix
- 16 x 24 + 4 cm, 120–130 µm, metallised, 500 g nuts, 350 g granola, 100 g chips
- 20 x 30 + 5 cm, 140–150 µm, foil, 1 kg nuts, 750 g granola
- 24 x 35 + 6 cm, 150–160 µm, foil, 1.5–2 kg bulk and food-service packs
Above 1 kg, a flat-bottom bag stands more reliably.
FAQ
What size stand-up pouch holds 250 g of nuts?
A 13 x 20 cm stand-up pouch with a 4 cm bottom gusset holds 250 g of almonds, cashews or peanuts with room for the zipper.
What size stand-up pouch holds 1 kg of granola?
Granola is lighter than nuts, so 1 kg needs a 24 x 35 + 6 cm pouch; a 20 x 30 + 5 cm pouch holds about 750 g of granola or 1 kg of nuts.
How thick should a snack stand-up pouch be?
Snack stand-up pouches are usually 100–110 µm total for 50–250 g, 120–130 µm for 500 g and 140–160 µm for 1 kg and above.
Do snack pouches need a foil layer?
Foil (PET/AL/PE) is only needed for oily nuts and seeds with a shelf life over 12 months; metallised PET is enough for granola, trail mix and roasted nuts sold within 9–12 months.
