What size custom cannabis mylar bag fits 3.5g, 7g, 14g and 28g flower?

What are the standard dispensary mylar bag dimensions from 1g to 28g?

Across single-state and multi-state dispensary operations, retail flower and edible skus cluster into six core pouch footprints. Remember that flexible packaging is always specified by flat outside dimensions in the order Width (left to right) × Height (bottom to top lip) × Bottom Gusset (expanded depth of the base fold). Side heat seals take up ¼ to ⅜ inch per edge, and a two-step locking header consumes the top 1.75 to 2.25 inches of height. Use the dispensary sizing chart below to benchmark your product line before requesting a quote for custom printed cannabis mylar bags. Notice that 3.5g eighths split into two popular footprints: a compact 3.5 × 5 × 1.5 inch pouch for dense indoor indica buds, and a roomier 4 × 6 × 2 inch pouch that fits fluffy sativa colas plus a two-way humidity packet.

Why do sativa and hybrid buds need a deeper bottom gusset than indica buds?

Two 3.5 gram eighths weighed on a calibrated scale can occupy very different cubic volumes depending on genetics and trim style. Tight, golf-ball-shaped indoor indica buds have high bulk density and settle into the bottom 2 inches of a pouch. Long, foxtailed sativa colas and hand-trimmed craft hybrids have an open, airy structure that takes up 25% to 40% more cubic volume for the exact same 3.5 gram net weight. If you size your entire brand around your densest indica cultivar, your packing crew will have to force larger sativa colas past the zipper throat, snapping delicate sugar leaves and smearing resin heads against the inside wall. Choosing a 4 × 6 × 2 inch stand-up bag gives you a full 2-inch expanded bottom gusset that forms a protective dome at the base of the pouch. When packed upright in master display cartons, that expanded base carries the vertical weight of the stack so the buds inside are never pinched.

1. Dense indica / machine-trimmed smalls (3.5g): fit comfortably in a 3.5 × 5 × 1.5 inch stand-up bag.
2. Fluffy sativa / hand-trimmed crown colas (3.5g): step up to a 4 × 6 × 2 inch stand-up bag with a full 2-inch bottom gusset.
3. Quarter-ounce (7g) whole-bud packs: use at least a 2.5 inch bottom gusset (4.5 × 7 × 2.5 in) so four to six medium colas sit side by side without stacking tightly.
4. Ounce (28g) bags: pair a 3.5 inch bottom gusset with a thicker barrier laminate so the tall bag stands upright on dispensary shelves.

How do humidity control packs and locking zippers change your bag height?

To keep cured flower at an ideal 58% to 62% relative humidity between harvest pack-out and the day a customer opens the pouch, many cultivators drop a two-way humidity control sachet (such as a Size 1 or Size 4 packet measuring roughly 1.5 × 2 inches to 2.75 × 2.5 inches) into every eighth, quarter and ounce bag. While thin, that square packet stiffens one interior wall and displaces about ½ inch of usable vertical height. At the same time, regulated markets typically require two-step closures, where pinch-and-slide or press-to-lock zippers and certified partner facilities are available on request. Because a two-step locking flange takes up the top 1.75 to 2.25 inches of the pouch height, a 5-inch-tall bag only leaves about 2.5 inches of vertical pocket after accounting for the bottom gusset pull-down. Stepping up to a 6-inch outer height on your eighth bag ensures neither the flower buds nor the corner of the humidity sachet rubs against the locking zipper ribs.

What size barrier pouch fits infused gummies, pre-rolls and concentrates?

Dispensary shelves hold far more than loose flower, and each product category has its own geometry. Infused pectin gummies or fruit chews sold in 10-count or 20-count multi-serving packs (typically 30g to 90g net weight) sit low in the bag and often include a small parchment divider or food-safe desiccant; they fit cleanly in a 4 × 6 × 2 inch stand-up bag or a 3.75 × 5 × 1.5 inch compact pouch. Pre-roll cones, infused blunts and disposable vape pens need a completely different aspect ratio: narrow width paired with tall vertical height. Standard 84mm, 98mm and 109mm king-size cones in a 2-pack to 5-pack tray or plastic insert fit a 3.5 × 7 × 0 inch flat pouch or a 3.75 × 7.5 × 1.5 inch gusseted barrier bag. Concentrates sold in 1-gram glass dab jars or parchment envelopes use compact 3 × 4.5 inch or 3.5 × 5 inch flat 3-side-seal pouches, or pair with our custom pre-roll boxes and custom vape cartridge boxes.

1. 10-count to 20-count infused gummies: 3.5 × 5 × 1.5 in or 4 × 6 × 2 in stand-up bag with food-safe inner seal layers on request.
2. Single or multi-pack pre-rolls (84mm to 109mm cones): 3.25 × 6.5 in or 3.75 × 7.5 × 1.5 in tall barrier pouch.
3. 1g concentrate parchment or mini glass jar: 3 × 4.5 in or 3.5 × 5 in flat 3-side-seal pouch.
4. Dispensary retail exit bags: 8 × 10 × 3 in or 9 × 12 × 4 in opaque reclosable bag to hold multiple items at checkout.

Does my bag size leave enough flat room for track-and-trace and lab test stickers?

Before locking in a compact pouch size like 3 × 4.5 inches or 3.5 × 5 inches, flip the bag over and measure the flat area available for mandatory state labeling. Many states require warnings, symbols and a batch or tracking label on the package; check your state's rules for exactly what goes where, including any variable compliance sticker carrying the state track-and-trace UID barcode, batch number, harvest date, cannabinoid percentages and COA QR code. On a 3.5 × 5 inch bag, once you subtract ⅝ inch for the left and right side seals, 2 inches at the top for the locking zipper header, and ¾ inch at the bottom for the gusset crease, the flat middle canvas is only about 2.85 × 2.25 inches. If your dispensary's thermal-transfer compliance sticker is 2 × 3 inches, it will not fit without crossing the lumpy zipper weld. Stepping up to a 4 × 6 × 2 inch eighth bag gives you a generous 3.35 × 3.25 inch flat back zone - or you can pair your pouches with custom-sized custom cannabis labels and custom smell-proof mylar bags.

1. Measure your thermal printer label first: check whether your seed-to-sale UID and potency sticker is 1.5 × 2.5 in, 2 × 3 in or 2 × 4 in.
2. Check flat back height: Flat Back Height = Outside Height − 2.0 in (CR header) − 0.75 in (bottom gusset crease).
3. Sample check before full run: order our $50 sample kit or a paid custom sample (credited to your full order) and review your free 2D dieline and 3D mockup before payment.

What are the most common cannabis mylar bag sizing mistakes?

Sizing a pouch for cured flower or edibles is about protecting trichomes and fitting state stickers as much as gram weight. Avoid these five errors

1. Packing 3.5g of whole flower buds into a flat zero-gusset pouch, which flattens colas and knocks trichomes off the bracts during shipping.
2. Sizing your eighth bag on dense indica nugs alone, leaving no room for fluffier sativa harvests or a two-way humidity packet.
3. Forgetting that a two-step locking zipper flange consumes the top 1.75 to 2.25 inches of bag height, which pushes buds up into the seal track.
4. Choosing a small 3.5 × 5 inch bag when your operations team uses a 2 × 3 inch track-and-trace and potency sticker that needs a 4 × 6 inch back panel.
5. Ordering a tall pre-roll pouch without adding ¾ inch of extra width to clear the stiff corner crush welds of the locking zipper.
