Coffee bag sizes run by roasted weight, not a generic small-medium-large scale. A 12oz side-gusset bag is approximately 5×8.5 inches with a 2.5-inch gusset. A 1lb flat-bottom pouch is approximately 5.5×8.25 inches with a 2.75-inch base. A 2lb side-gusset bag runs approximately 7×12 inches with a 4-inch gusset. This guide charts every common coffee bag size, from 2oz samples up to 5lb wholesale bags, in both formats. Related reading: our mylar bag fill weight chart and the original mylar bag sizes guide. For everything else, our full box size guide covers the rest.
A roaster sells coffee by weight, so the bag has to match that weight exactly. A 12oz bag and a 1lb bag hold different volumes of roasted beans. Whole bean coffee is fairly consistent in density across most roasts, though. Coffee bag sizes stay standardized around common retail weights for this reason. It keeps ordering simple across an entire product line.
There’s a second reason too. Roasted coffee off-gasses carbon dioxide for days after roasting. A bag sized correctly leaves room for that gas to expand without bursting a seam. That’s part of why nearly every coffee bag size includes a one-way degassing valve, not just the larger wholesale formats.
Weight | Width (in) | Height (in) | Gusset (in) | Typical Use |
|---|---|---|---|---|
2oz | 3.5 | 5.5 | 1.5 | Sample or cupping bag |
4oz | 4 | 6.5 | 2 | Sample or gift-set bag |
8oz | 4.5 | 7.5 | 2.25 | Small retail or café shelf |
12oz | 5 | 8.5 | 2.5 | Standard retail shelf |
1lb | 6 | 9.5 | 3 | Specialty roaster standard |
2lb | 7 | 12 | 4 | Wholesale and cafe accounts |
5lb | 8.5 | 14.5 | 5 | Bulk and wholesale sales |
The 12oz and 1lb tiers are this chart’s real workhorses. Most specialty roasters build their whole retail line around those two sizes before adding samples or bulk formats.
A flat bottom pouch sits differently on a shelf than a side-gusset bag does. It stands square, with a rigid base rather than a folded side seam. That squared stance reads as a more premium format on a shelf. Flat bottom dimensions are expressed as width × height plus base depth. That’s different from a side-gusset bag’s width × height plus gusset format.
Weight | Width (in) | Height (in) | Base Depth (in) |
|---|---|---|---|
8oz | 5.3 | 7.9 | 2.75 |
1lb | 5.5 | 8.25 | 2.75 |
1lb (large) | 5.9 | 12.8 | 3.75 |
Flat bottom bags run a little larger than a side-gusset bag of the same weight. The squared base eats some interior volume that a folded gusset doesn’t. Confirm actual fill capacity against your specific roast’s density rather than assuming a direct swap between formats.
A one-way degassing valve lets built-up CO2 escape without letting outside air in. It sits on the upper front panel, usually centered or slightly off to one side. Almost every coffee bag size above 4oz ships with one as standard. Even smaller sample bags increasingly include it now, for beans roasted within the past week.
A few Easy Box Packaging products that fit what this article covers.
Mylar Bags
Flat mylar bags are flat or lightly gusseted flexible pouches printed around a measured product, opening route, and barrier requirement. Choose food-grade film, a metalized or foil laminate when appropriate, a zipper or heat-seal closure, and a finish that suits the artwork. Share the packed width, height, thickness, weight, artwork, and storage context so the dieline is built around the actual fill.

Mylar Bags
Custom mylar bags with window are food-grade flexible pouches printed around the pack format, closure, and storage routine. Choose a flat or gusseted profile, a zipper or heat-seal finish, and a barrier laminate that matches the product. Share the packed pack dimensions, weight, seal area, artwork, and finish direction so the dieline is built around the real dry-food pack.

Gift Boxes
Custom gift bags built as made-to-order kraft or SBS paperboard totes with rope or ribbon handles. Printed with your own branding and finished with foil stamping or lamination, they're sized around what they're carrying rather than sold as one fixed shape.

Gift Boxes
Custom packaging for a curated set of coffee bags, sized around your actual bag count and dimensions, with a fitted kraft paperboard tray that holds each stand-up pouch upright and separated inside a folding carton built to ship flat until it's assembled.

Retail & Product Boxes
Custom kraft product boxes pair a natural brown paperboard surface with printed artwork for individual retail items. Plan the carton around your packed dimensions, opening direction and shelf presentation, then review print coverage and any internal support with the proposed structure. Board grade and finish suitability are checked for the specific item.

Retail and Tote Bags
Custom paper grocery bags are gusseted kraft paperboard carry bags for pantry, market, and food retail, sized around the load and printed with your branding.
Request a QuoteClosure type changes a bag’s usable height more than most roasters expect going in. A resealable zipper adds roughly half an inch of dead space at the top. That’s space you lose before you even reach the fill line. A heat-seal-only bag skips that allowance, so the same stated height holds slightly more product. Factor the closure into your fill-weight math, not just the bag’s outer dimensions.
Start with the front panel’s usable area, not the bag’s total width and height. Subtract the valve zone at top, any side-seal margin, and the bottom gusset or base fold from the outer dimensions. What’s left is the space your label or direct print actually has to work with.
I’ve seen roasters design a label at full bag width. It printed over the side seam once the bag was filled and sealed. Leave at least a quarter-inch of margin on every edge of your label artwork. That buffer accounts for normal variance in bag-to-bag sealing, which is common even with a consistent supplier.
The standard coffee bag sizes above cover most roasters. Not every product fits neatly into a 12oz or 1lb slot, though. A subscription box running an unusual weight tier can need a size that doesn’t exist off the shelf. So can a gift set pairing coffee with a mug, or a co-branded run for a wholesale account. Trying to force an odd product into a stock bag usually means wasted headspace or an awkward fill line. Sometimes the valve ends up placed somewhere it doesn’t belong.
Standard sizes are the right starting point for almost every roaster. The chart above should cover the bulk of a normal product line. When a specific order doesn’t fit, EBP cuts mylar and stand-up pouches to any custom dimension. Valve placement and closure type get built to the actual product, not the nearest standard slot. That flexibility matters more for coffee than for most flexible packaging. A bag that’s even slightly undersized can trap enough CO2 pressure to strain a seal.
Coffee bag sizes track roasted weight, from a 2oz sample up to a 5lb wholesale format. Either side-gusset or flat-bottom construction works, depending on the shelf look you want. Match the bag to your weight and closure needs first. Then size the label to the panel that’s actually left over. Need custom dimensions or a specific barrier spec?

Questions, answered
A standard 12oz side-gusset coffee bag measures approximately 5 inches wide by 8.5 inches tall, with a 2.5-inch gusset. Exact dimensions shift slightly by supplier and by whether the bag includes a valve.
Most coffee bag sizes above 4oz ship with one as standard. Fresh-roasted beans continue releasing CO2 for days after roasting. Smaller sample bags sometimes skip it if the coffee will be used within a day or two of roasting.
A side-gusset bag folds flat with pleated sides and a soft bottom seam. A flat-bottom bag has a rigid, squared base that lets it stand upright on a shelf. Flat-bottom bags typically run slightly larger than a side-gusset bag of the same stated weight.
Yes. Standard coffee bag sizes cover most roasters. Custom dimensions are available for unusual weights, gift sets, or co-branded wholesale runs. Valve placement and closure type can be built around the specific product rather than forced into a standard slot.
