Ordering custom eco bags sounds simple until you sit down to actually specify them. How big should they be? Which fabric suits your products? Will the bag hold what your customers buy, and will it look right carrying your logo? Get these decisions wrong and you end up with thousands of bags nobody wants to use.
Size and material are the two choices that shape everything else about a custom bag, including cost, durability, and how customers perceive your brand. This guide walks Canadian business owners through both decisions step by step, with practical sizing benchmarks, material comparisons, and real world examples so you can order with confidence the first time.
Why Size and Material Matter More Than Anything Else
Size and material decide whether a bag actually works in daily life. A beautiful bag that is too small for a customer’s purchase, or too flimsy for the weight, simply will not get reused.
These two choices also drive your budget. Larger bags use more fabric, and premium materials cost more per unit, so they directly affect your cost per bag and your total order value.
The right combination creates a bag that customers keep, reuse, and carry in public, which is exactly where your branding earns its return.
Step 1: Define What the Bag Needs to Carry
Before thinking about fabrics or dimensions, start with the contents. This single question answers most of your specification.
Ask yourself:
- What products will customers put in this bag?
- How heavy is a typical purchase?
- Are the items bulky, fragile, or awkwardly shaped?
- Will the bag hold food, liquids, or temperature sensitive goods?
- Do customers usually buy one item or a full basket?
A bookstore, a grocery chain, and a winery all need very different bags. Matching the bag to real purchase behaviour is the foundation of a good reusable bag order.
Step 2: Choosing the Right Bag Size
Once you know what goes inside, sizing becomes much easier. Custom bags are typically measured as width by height by gusset depth.
Common Reusable Bag Size Ranges
| Bag Size | Typical Dimensions | Best For |
| Small | Around 8 x 10 inches | Cosmetics, jewellery, small gifts |
| Medium | Around 13 x 15 inches | Retail purchases, books, clothing |
| Large | Around 15 x 16 inches with gusset | Groceries, bulk items |
| Extra large | 18 inches and above | Shopping hauls, events, tradeshows |
| Wine and bottle | Tall and narrow, often 6 x 14 inches | Wine, spirits, bottled products |
These are general benchmarks rather than fixed rules. The right size always comes back to what your customers actually carry.
Do Not Forget the Gusset
The gusset is the side and bottom depth that gives a bag its capacity. A flat bag with no gusset holds far less than its dimensions suggest.
For groceries and bulky items, a deeper gusset makes the difference between a bag that stands upright and one that collapses. It also helps the bag hold its shape, which keeps your printed logo visible and flat.
Step 3: Choosing the Right Material
Material determines durability, appearance, and cost. Each option suits a different purpose and price point.
Cotton
Soft, premium, and washable, with an excellent surface for detailed printing. Best for boutiques, fashion, cafes, and brands that want a keepsake quality tote.
Non Woven Polypropylene
Affordable, water resistant, and lightweight yet strong. The practical choice for grocery chains, pharmacies, and high volume promotional campaigns.
Jute
Rustic, extremely strong, and visibly sustainable. Ideal for gourmet food, gift packaging, farmers’ markets, and premium presentation.
RPET
Made from recycled plastic bottles, durable and water resistant. A strong option for businesses prioritizing recycled content and everyday practicality.
Bamboo and Blended Fabrics
Natural, distinctive, and increasingly popular for brands wanting something beyond standard options while maintaining eco credentials.
Matching Size and Material Together
Size and material are not separate decisions. Larger bags carrying heavier loads need stronger fabrics and reinforced construction.
- Large grocery bags: high GSM non woven, RPET, or heavyweight cotton
- Medium retail totes: cotton or mid weight non woven
- Small gift bags: lighter cotton or laminated finishes
- Bottle bags: structured jute or cotton with reinforced bases
Businesses handling food or temperature sensitive orders often add insulated thermal bags in larger sizes, where both capacity and structure matter equally.
Fabric Weight and Why GSM Matters
GSM, or grams per square metre, measures how heavy and dense a fabric is. It is one of the clearest indicators of durability.
Higher GSM means thicker, stronger material that resists tearing and stretching. Lower GSM keeps costs down but suits lighter loads only. As a rough guide, promotional giveaways can use lighter fabrics, while grocery and heavy retail use should always specify a higher weight.
Always ask your supplier for the GSM rather than relying on how a sample feels.
Design Features Worth Specifying
Beyond size and fabric, a few practical features improve usability considerably.
- Reinforced bases for heavy loads
- Wider handles for comfort, and longer handles for shoulder carrying
- Laminated finishes for water resistance and easy cleaning
- Fold flat designs so customers can store bags easily
- Internal pockets for added functionality
Each feature adds cost, so choose the ones that genuinely improve how your customers use the bag.
Branding and Print Considerations
Your size and material choices directly affect how your logo looks.
Cotton and non woven fabrics offer smooth surfaces suited to detailed, full colour artwork. Jute has a coarser texture that works best with bold, simpler designs. Larger bags give more print area, while smaller bags require tighter, cleaner artwork.
Presentation focused products such as reusable wine bags show this clearly, where a narrow shape and premium fabric combine to make even a simple logo look elevated.
Industry Applications and Real World Examples
Here is how different Canadian businesses typically approach these choices.
- Grocery stores: large, high GSM non woven bags with deep gussets and reinforced bases
- Boutiques and fashion retail: medium cotton totes with detailed printing
- Wineries and liquor stores: tall bottle bags in jute or cotton with dividers
- Pharmacies: medium, wipeable non woven bags with water resistance
- Cafes and takeout: insulated or laminated bags sized for containers
- Tradeshows and events: large, lightweight bags with maximum print area
Many retailers also stock sustainable paper bag options alongside reusables to give customers a choice at checkout.
Cost Savings Through Smart Specification
Over specifying wastes money, and under specifying wastes bags. The goal is to match quality to purpose.
A promotional giveaway does not need grocery grade construction, and a grocery bag should never be built like a giveaway. Ordering the right specification the first time avoids costly reorders and replacement runs. Requesting a custom quote with your sizes, materials, and volumes lets you compare options and find the best balance before committing.
Sustainability Advantages of Choosing Correctly
Choosing the right size and material is itself a sustainability decision.
- Correctly sized bags reduce material waste in production
- Durable materials extend lifespan and lower impact per use
- Recycled and natural content lowers the footprint at the source
- Bags customers actually reuse replace far more disposables
A bag that fits its purpose gets used repeatedly, and reuse is where the real environmental benefit lives.
Regulatory Compliance in Canada
Canada continues to phase out single use plastics through federal regulations, with provinces and municipalities adding their own bans and fees on disposable bags.
Choosing durable, reusable materials helps businesses stay compliant while meeting customer expectations. Confirm that your chosen materials meet local recycling or compostability standards, and that inks and fabrics are certified free of lead and other contaminants.
Market Demand and Buyer Behaviour Trends
Canadian businesses are becoming far more specific about what they order. A few years ago, most simply requested a standard tote. Today, buyers ask about GSM, gusset depth, recycled content, and load capacity.
Demand is also shifting toward larger, sturdier bags as customers use them for full grocery shops rather than single purchases. Premium materials like cotton and jute are growing in categories where presentation matters, while recycled content non woven remains dominant for volume. This move toward precise, purpose built specifications shows no sign of slowing.

Frequently Asked Questions
What is the most common size for a reusable shopping bag?
The most common size sits around 13 to 15 inches wide and 15 to 16 inches tall with a gusset. This range suits general retail and grocery use comfortably. The right size still depends on what your customers typically purchase and carry.
How do I know what size custom eco bag my business needs?
Start with what customers actually buy. Measure a typical purchase, consider weight and bulk, then choose dimensions with a little room to spare. A gusset adds capacity without increasing the bag’s flat dimensions, which makes it especially useful for groceries.
Which material is best for custom eco bags?
It depends on your goals. Non woven suits high volume and low cost, cotton offers a premium feel and detailed printing, jute delivers strength and visible sustainability, and RPET provides recycled content with water resistance. Match the material to your budget and use case.
What does GSM mean when ordering reusable bags?
GSM measures grams per square metre and indicates fabric weight and thickness. Higher GSM means stronger, more durable material suited to heavy loads. Lower GSM reduces cost but suits lighter use only. Always confirm GSM with your supplier before ordering.
How much weight can a custom eco bag hold?
Capacity varies by material, fabric weight, and construction. Well made grocery bags with reinforced bases handle substantial loads, while lightweight promotional totes suit lighter items. Ask your supplier for tested load capacity rather than assuming a bag will handle heavy contents.
Does bag size affect the printing area?
Yes, larger bags provide more surface for artwork and allow bolder, more detailed designs. Smaller bags require tighter, simpler layouts to stay legible. Material texture also matters, since smooth fabrics reproduce fine detail better than coarse weaves like jute.
Can I order custom eco bags in multiple sizes?
Most businesses do. Offering several sizes lets customers choose what suits their purchase, which increases reuse. Many retailers order a large grocery size alongside a medium retail tote, and add specialty sizes such as bottle bags for specific product categories.
How do I balance quality and cost when ordering?
Match the specification to the purpose rather than defaulting to the cheapest or the most premium option. Promotional giveaways can use lighter fabrics, while grocery bags need higher GSM and reinforced construction. Ordering the right spec first time avoids expensive reorders later.
