A cotton tote bag's size is written in centimetres, first width, then height (and the gusset, if it has one); there is no official standard. Among the 171 products in our catalogue with a stated size, 50x40, 30x40 and 45x35 appear most often. The right size is chosen by the size of the product you will put in it, how it will be carried and whether you need a gusset; a custom size can also be produced for a different need.
A common mistake when ordering cotton tote bags is choosing the size by eye: the model either does not take the product or leaves unnecessary empty space, and the logo also appears in the wrong proportion. To decide the size, you first need to know what the bag will carry.
In this guide we have gathered how sizes are read, the commonly used sizes in our catalogue, the choice of gusset and fabric weight (gsm), the logic of handle and carrying capacity, and what information to prepare for a custom-size request.
How Is a Cotton Tote Bag Size Written and Read?
Cotton tote bag sizes are written in centimetres, mostly in the order width, then height. When you say 30x40, a model about 30 cm wide and 40 cm high is meant. Gusseted models add a third value, the gusset, which gives the depth of the bag. Because the same numbers may not be read the same way everywhere, you need to ask how the size is written from the start.
Because of the stitching or welding allowance, the inside size is usually a little smaller than the written outside size. Plan for your product not by its exact size, but by leaving a few centimetres of room on every side. Confirming the following three points before ordering prevents misunderstandings and surprises that can arise after approval:
- Is the written size the outside size of the finished bag, or the size of the cut fabric?
- Is the handle included in the size, or is only the body written?
- If there is a gusset, is the depth measured with the gusset fully opened?
Are There Standard Cotton Tote Bag Sizes?
There is no official size standard for cotton tote bags; when people say "standard", they actually mean commonly used sizes. Among the 171 products with a stated size in our catalogue, bag widths vary from 11.5 to 55 cm and heights from 8.5 to 60 cm. The smallest examples are pocket-sized models such as 15x20 or 26x19.
The table below shows the distribution in the catalogue, not a ranking of preference. That a size appears often does not mean it suits your job; what decides is the product you will put in it. The last column is a general comment indicating a reasonable starting point for each size and should not be taken as a commitment for any particular product.
| Size | Number of Products | Generally suitable use |
|---|---|---|
| 50x40 | 11 | Wide, landscape shape; clothing package, boxed product, several items together |
| 30x40 | 11 | A4 folders, catalogues, books and training sets |
| 45x35 | 10 | Landscape shape; clothing, boxes and packaged products |
| 33x45 | 7 | Upright and tall; folders, book stacks, long products |
| 35x45 | 7 | Upright and wide; books, notebook sets, large gift packages |
| 30x35 | 6 | A4 folders, brochures and small gift boxes |
| 35x40 | 6 | Medium size, multi-purpose use |
30x40, 35x40 or 50x40: Which Suits You?
When choosing a size, start in reverse: measure the largest product that will go in the bag, then add a few centimetres in every direction. For an easy comparison, you can use an A4 sheet of paper (21x29.7 cm). If you will hand out A4 folders or brochures, the 30x35 and 30x40 models take the paper without folding it; if you will also add a thick folder or box, you should look at wider and gusseted options.
The pairing below is not a rule but a starting point that makes deciding easier and makes the conversation concrete. Confirm the final size by comparing it with your product's real dimensions, if possible by placing the product on a bag outline drawn on paper; this prevents the approved size from turning out too tight or too loose later.
- Cards, jewellery, small gifts: small models such as 15x20 or 26x19.
- Brochures, catalogues and A4 folders: 30x35, 30x40 and 33x45.
- Clothing, boxed products, several packages: wide models such as 45x35 and 50x40.
- Groceries and heavy shopping: fabric thickness and handle strength matter more than size.
When Should You Choose a Gusseted Bag?
A gusset is a strip of fabric added to the side or bottom of the bag; it opens as the bag fills and gives it depth. Of the 171 products with a size stated in our catalogue, 95 are gusseted (side or bottom gusset) and 76 are without a gusset. The most common gussets are 8 cm and 10 cm, meaning that roughly that much depth is created when the gusset opens.
If you will carry books, boxed products or several packages together, a gusset lets the bag stand upright and lets the product sit without lying flat. If you will carry only flat items such as folders, brochures and catalogues, a flat bag without a gusset is enough; the print surface also stays flat. Whether the gusset is at the side or the bottom is chosen according to the shape of the product.
What Do Cotton Tote Bag Weight and Nonwoven Weight (gsm) Mean?
Fabric weight (gsm) is the weight of one square metre of fabric in grams; as the number rises, the fabric is generally thicker and sturdier. In the catalogue, the weight appears on two nonwoven fabrics: 60 gsm for ultrasonic bags and 100 gsm for stitched nonwoven bags. Production in other weights is also possible; which is suitable is settled in the quote.
We do not state fabric weight on product pages for cotton tote bags; the thickness is chosen together during the quote, looking at the load it will carry. A thick fabric makes the bag sturdier but takes up more space when folded and increases the volume of bulk shipments. If you will distribute in large numbers, thinking about weight and volume together also helps logistically.
| Bag Type | Fabric structure | Fabric weight in the catalogue |
|---|---|---|
| Ultrasonic-welded nonwoven bag | Nonwoven (non-woven) | 60 gsm |
| Stitched nonwoven bag | Nonwoven (non-woven) | 100 gsm |
| Cotton tote bag (raw cotton, coloured fabric) | Woven cotton fabric | Weight not stated, chosen in the quote according to load |
| Request for a different fabric weight | Nonwoven | Can be produced, settled in the quote |
How Should You Think About Carrying Capacity and Handle Length?
How many kilograms a bag will carry does not depend on a single number: the thickness of the fabric, the stitching or welding points, the strength of the point where the handle is attached and the size of the bag together determine it. We do not state a carrying value in kilograms or a handle length in centimetres in the catalogue; so instead of giving a number, we talk about what you will carry. The logic below helps when choosing a handle.
- A short handle is enough for a bag carried by hand.
- If it will be hung on the shoulder, the handle should be long enough not to slip off the shoulder even over thick clothing.
- On a wide landscape model, a very short handle makes use difficult; the handle should be chosen in proportion to the bag's size.
- If you will carry heavy loads, ask separately about the point where the handle joins the body; as the load increases, that is the point under most strain.
What Should You Prepare for a Custom-Size Cotton Tote Bag?
If the ready-made sizes do not suit your job, a cotton tote bag can be made in a custom size. Because fabric, size, gusset, handle and print area affect one another, the easiest place to start is by measuring the product you will put in the bag. Writing down the information below when you send your request makes it easier for us to prepare the right quote and to settle the size together:
The process runs in the order of request, quote, design approval, production and printing; we check the logo placement and the size together at the design stage, and production does not start without your approval. If you are undecided about the size at the quote stage, it is enough to say so. If you would like a sample, mention it during the quote; whether one is available and on what terms is settled at that stage.
- The width, length and height of the largest product that will go in the bag, and its approximate weight
- The approximate total order quantity and whether it will be bought in one go
- Fabric preference: cotton, stitched nonwoven or ultrasonic nonwoven
- Whether you want a gusset, and whether the handle is for carrying by hand or on the shoulder
- The logo file and the number of colours in the print
