Choosing the right paper bag is not simply a matter of choosing a larger or smaller size.
For importers and distributors, several details need to be considered:
How wide should the bag be?
How tall should it be?
Does it need a gusset?
Should it have handles?
What type of product will go inside?
And should the dimensions be specified in centimetres or inches?
Different markets and applications can require very different paper bag structures.
This Paper Bag Sizes and Shapes Guide explains the basic dimensions and helps buyers understand how to select the right format for foodservice, bakery, takeaway and retail applications.
How Are Paper Bag Sizes Measured?
Unlike a round paper plate, a paper bag usually has several dimensions.
Depending on the bag structure, the specification may include:
Width × Height × Gusset
For example, a bag specification might be expressed as:
18 × 22 × 8cm
This means the bag has a defined width, height and side/bottom gusset.
For shopping bags with handles, the handle type and handle position may also be part of the specification.
This is why simply asking for a “medium paper bag” can sometimes lead to misunderstandings.
For international sourcing, it is better to provide the exact dimensions and, where possible, a reference sample or drawing.
Small Paper Bags
Small paper bags are commonly used for lightweight products.
Typical applications can include:
- Bakery products
- Snacks
- Small takeaway items
- Candy
- Small retail products
- Gifts
The exact dimensions depend on the product.
A bakery bag for one pastry may need a completely different structure from a small shopping bag.
The bag should therefore be designed around the product rather than selected only by nominal size.
Medium Paper Bags
Medium-size bags are commonly used for takeaway food, bakery products, retail products and everyday shopping applications.
They provide more capacity while remaining relatively easy to handle and store.
For foodservice applications, buyers should also consider the bag opening, gusset and bottom construction.
A bag that is wide enough for the product but does not have enough gusset may not be practical.
Large Paper Shopping Bags
Larger paper bags are often used for retail and shopping applications.
They may carry clothing, shoes, packaged products, gifts or other relatively bulky goods.
Because the product weight can be higher, paper specification and handle construction become increasingly important.
A large shopping bag should not simply be made by scaling up a small bag.
The structure, paper weight, bottom and handles all need to be considered together.
Paper Food Bags vs Shopping Bags
Food bags and retail shopping bags can look similar, but their requirements are often different.
A food bag may focus on:
- Food contact suitability
- Easy opening
- Lightweight construction
- Practical packing
- Bakery or takeaway use
A retail shopping bag may focus more on:
- Appearance
- Branding
- Handle strength
- Carrying comfort
- Larger dimensions
- Product presentation
Understanding the application helps determine the appropriate construction.
Flat Bags, Gusset Bags and Shopping Bags
Paper bags can have different structures depending on their application.
A flat paper bag is relatively simple and can be useful for lightweight food or bakery products.
A gusseted bag provides additional space and can be more suitable for products with greater volume.
Shopping bags generally have a more structured construction and may include paper handles.
There is no single “best” bag shape.
The correct structure depends on the product that needs to go inside.
CM or Inch?
For international buyers, the same issue appears with paper bags as with many packaging products.
North American buyers may commonly specify dimensions in inches.
European and Asian buyers frequently use centimetres or millimetres.
For international projects, providing both can reduce misunderstandings.
For example:
18 × 22 × 8cm / approximately 7 × 8.7 × 3.1in
However, the safest approach is always to confirm the actual finished dimensions with the supplier.
Small differences in width, height or gusset can affect how a product fits inside the bag.
What About Handles?
For shopping bags, size is only one part of the specification.
The handle can significantly affect the final product.
Common options include different paper handle constructions, depending on the bag design and application.
The handle position, attachment method and overall bag structure need to work together.
For heavier retail products, buyers should pay particular attention to handle attachment and the bag’s overall load requirements.
How Should You Choose the Right Paper Bag Size?
Start with the product.
Measure the product’s:
Width × Height × Depth
Then consider how much additional space is needed for easy insertion and removal.
For food products, also consider whether the bag needs room for multiple items.
For retail products, consider whether the bag needs to stand upright and whether customers will carry it by hand.
For takeaway applications, the opening and gusset can be just as important as the overall height.
Don’t Choose Size Alone
Paper bag specifications also depend on:
- Paper type
- Paper weight
- Bag structure
- Gusset
- Bottom construction
- Handle type
- Printing
- Product weight
- Packaging quantity
A large lightweight bag may not be suitable for a heavy product.
Similarly, a small bag does not necessarily need very heavy paper.
The goal is to create a specification that is appropriate for the product and application.
