The right non-woven bag size depends on what you need to carry, how the items will sit inside, and whether the bag has a flat or expanded base. A small gift bag needs different proportions from a conference bag, while a grocery shopper often needs more depth rather than extra height.
There is no single S, M, or L measurement shared by every supplier. Use the reference sizes below to narrow your options, then check the complete dimensions of your contents before choosing a bag.
Non-Woven Bag Size Chart
A useful starting point is to compare small, medium, and large formats. In this guide, dimensions follow width × height × depth (W × H × D). Height refers to the bag body and excludes the handles.
| Reference size | Dimensions: W × H × D (cm) | Approximate dimensions (inches) | General purpose |
|---|---|---|---|
| Small | 20 × 25 × 10 | 7.9 × 9.8 × 3.9 | Small gifts, accessories, and compact retail items |
| Médio | 30 × 38 × 10 | 11.8 × 15.0 × 3.9 | Documents, light event packs, and some folded clothing |
| Large | 40 × 45 × 15 | 15.7 × 17.7 × 5.9 | Multiple retail items, bulkier clothing, and shopping |
These are selection examples, not universal industry standards or a list of stock sizes. The best fit depends on the finished bag construction and the actual items being packed.
For a flat bag without a gusset, dimensions normally show width and height only. Do not compare its carrying space directly with a gusseted bag simply because both have the same front-panel measurements. You can explore different non-woven bag styles alongside these reference dimensions.
How to Measure a Non-Woven Bag
Width, Height, and Depth
Measure the width across the front of the bag and the height from the base to the top edge of the bag body. For a gusseted bag, open the base and measure its front-to-back depth without stretching the material.
For tapered styles, the opening and base may have different widths. Record both when fitting a rigid box: a wide opening does not guarantee a wide enough base.
Keep handle measurements separate. Also confirm whether a supplier lists dimensions as W × H × D or in another order. Writing “30 cm wide × 38 cm high × 10 cm deep” removes ambiguity.
Flat Bags vs Gusseted Bags
A flat bag has no separately specified depth. When a thick object goes inside, the front and back panels wrap around it, using some of the available panel width and height.
A gusseted bag has folds or panels that expand to create depth. However, a bottom-gusset-only bag and a bag with both side and bottom gussets can open differently. For boxed products, check the expanded base and opening, rather than relying only on measurements taken while the bag is lying flat.
Non-Woven Bag Sizes for Different Uses
The table below connects specific reference dimensions with everyday applications. It includes different proportions because a taller bag is not always the most useful option.
| Use or scenario | Reference dimensions: W × H × D (cm) | Approximate dimensions (inches) | Suitable starting point for | Main fit check |
|---|---|---|---|---|
| Small gifts and accessories | 20 × 25 × 10 | 7.9 × 9.8 × 3.9 | Small gift boxes, accessories, and compact cosmetic packs | Measure the complete gift packaging |
| A4 documents, portrait format | 25 × 35 × 10 | 9.8 × 13.8 × 3.9 | Papers, brochures, and slim notebooks | Check the actual folder size and thickness of the stack |
| A4 documents, landscape format | 35 × 25 × 10 | 13.8 × 9.8 × 3.9 | Horizontally arranged document packs and event materials | Confirm that folders clear the opening and top edge |
| Folded clothing and light retail purchases | 30 × 38 × 10 | 11.8 × 15.0 × 3.9 | Some folded T-shirts, scarves, and small apparel purchases | Measure the folded bundle, including wrapping |
| Event packs with several items | 38 × 42 × 10 | 15.0 × 16.5 × 3.9 | Brochures, notebooks, and selected giveaways | Arrange the complete kit and check usable depth |
| Bulkier clothing or multiple purchases | 40 × 45 × 15 | 15.7 × 17.7 × 5.9 | Larger clothing bundles and mixed retail purchases | Check the bulkiest item and total carrying weight |
| Wide grocery or boxed-product shopper | 50 × 35 × 20 | 19.7 × 13.8 × 7.9 | Wider product arrangements and grocery combinations | Confirm the footprint, opening, and tested load suitability |
These dimensions are planning references, not guarantees that every item in a category will fit. Check a finished sample with your own products.
Small Gifts and Cosmetics
Start with the outside dimensions of the gift box or cosmetic packaging. Tissue paper, protective sleeves, and multiple items can make the final arrangement noticeably larger than the products alone.
A close fit can look tidy, but the bag should still allow easy loading and removal. Excess space may let small products move around, especially if the bag is deep but the contents are narrow.
For a single boxed item, choose proportions around that box. For a gift set, first decide whether the products will sit next to each other or be presented in one outer box. A candle and a skincare carton placed side by side can require more width than either product alone. Stacking may reduce the footprint, but it also changes the presentation and may put pressure on the lower package.
A4 Documents and Conference Materials
A4 paper measures 21 × 29.7 cm, but an A4 document bag needs room beyond the paper edges. Folders, bindings, and brochure stacks take up additional space.
A 25 × 35 × 10 cm portrait format is a useful starting point for a compact document pack. A 35 × 25 × 10 cm landscape format offers a different orientation. Neither should be selected solely from the “A4” label: measure the actual folder and everything that will accompany it.
For conference packs containing a bottle, notebook, and several giveaways, check the full arrangement. A document bag that works for brochures alone may be too narrow for the completed kit.
Consider three versions of the same event pack. A brochure-only handout may need little depth. Adding a notebook and pen box increases the thickness of the stack. Adding a bottle or boxed mug introduces a separate footprint that must fit alongside the documents. At that point, increasing the gusset or width can be more helpful than switching to a taller bag. Check whether attendees can retrieve the smaller items without removing the entire pack.
Clothing and Retail Purchases
Fold the garment as it will be handed to the customer before measuring. A thin T-shirt, a wrapped shirt, and a bulky sweater require different amounts of space.
Flat bags may work for thin purchases. Gusseted bags provide more room for thicker bundles or multiple items. If your store wants one bag size for several products, test representative orders, including a larger combination, before committing to that format.
A sample folded bundle measuring 27 × 32 × 7 cm could make a 30 × 38 × 10 cm bag worth testing, provided those are the bundle’s dimensions in the chosen carrying orientation. Adding another garment may increase its thickness beyond what the 10 cm gusset comfortably accommodates. Keeping a similar front-panel size and increasing the depth may then be a better starting point than moving to a much taller bag. This is an illustrative fit check, not a confirmed product capacity.
Shoeboxes and Other Boxed Products
For rigid packaging, the base is often the deciding measurement. Check the box’s footprint in its intended carrying position, then confirm the bag height.
For example, an illustrative box measuring 32 × 20 × 12 cm, carried flat, needs a usable base larger than 32 × 20 cm plus sufficient height and loading clearance. A bag with a 10 cm depth would not provide that footprint in the same orientation, regardless of how tall it is.
Shoe packaging varies, so no single reference size should be treated as suitable for every shoebox.
Groceries and Everyday Shopping
Grocery combinations benefit from a base that accommodates several items without forcing everything into a tall stack. Consider how bottles, cartons, and delicate goods will sit together.
Also consider the finished load. A bag can have enough room for a grocery order without being suitable for its weight. Material, seams, handle attachment, and reinforcement need to match the intended use.
Think about the journey as well as the checkout counter. A wide shopper may work well for transferring purchases to a car, while someone walking home needs a manageable loaded shape and comfortable handles. Avoid choosing an oversized bag just to accommodate an occasional unusually large order. Two manageable bags may be more practical, depending on the combined weight and the customer’s carrying needs.
Why Gusset Size Matters
Compare two bags measuring 30 × 38 × 10 cm e 30 × 38 × 15 cm. Their front panels have the same width and height, but the second has a deeper base.
As ideal rectangular shapes, their calculated volumes would be 11.4 and 17.1 liters. This illustrates the effect of depth; it is not a tested capacity rating. Flexible sides, seams, the opening, and the shape of the contents affect usable space.
A deeper gusset can help accommodate wider product arrangements. Extra height cannot solve a base that is too narrow for a box. Conversely, a deep bag may be unnecessary for a slim document pack.
Should You Choose a Wider, Taller, or Deeper Bag?
When two sizes look close, identify where the current fit fails before increasing every dimension.
If a box presses against the left and right sides, review the usable width. If it fits across the front but pushes the front and back panels outward, review the depth. If the base fits but the product protrudes or prevents the closure from working, review the height and closure clearance.
For example, comparing 30 × 38 × 10 cm with 35 × 38 × 10 cm helps you assess extra width while keeping height and depth unchanged. Comparing 30 × 38 × 10 cm with 30 × 38 × 15 cm isolates the effect of depth. These focused comparisons make sample feedback more useful than simply asking for the next size up.
When a bag seems too spacious, reduce the dimension creating the unwanted gap. A shorter body may improve access to a low gift box, while a shallower base may better suit documents. Keep enough clearance to load and remove the contents comfortably.
How to Check Whether Your Items Will Fit
1. Measure the Complete Packed Items
Include the outer box, tissue, protective wrapping, and any additional products. For multiple items, measure the intended arrangement rather than adding unrelated individual dimensions.
2. Decide How the Items Will Sit
Choose whether products will stand upright, lie flat, sit side by side, or stack. Keep fragile products in a suitable position and consider how the arrangement behaves when lifted.
3. Leave Space for Loading and Removal
The internal space should exceed the packed contents enough to make the bag practical to use. There is no single clearance allowance that works for every product.
Rigid boxes, soft clothing, and irregular gift sets behave differently. A zipper, flap, or other closure may also reduce the space available near the top.
4. Test a Finished Sample
Load the sample with the complete order and check that the opening is accessible, the base sits as intended, and the handles remain comfortable to use. If you specify a closure, test it with the bag filled.
Fit and strength are separate checks. A successful trial fit does not establish a safe carrying load.
How We Helped a UK Client Choose a Better Bag Size
Last year, a client from the UK contacted us about custom non-woven bags for a conference welcome kit. They already had a size in mind—25 × 35 × 10 cm—and wanted us to produce the bags to those dimensions. Since the kit included A4 documents, they felt this size would be suitable.
Before moving ahead, we asked what else would go inside. The full kit included an A4 folder, a notebook, a boxed mug, and a pen. After reviewing the packaging dimensions and how the items would sit together, we noticed that the proposed 10 cm depth would leave very little room. The mug box alone occupied approximately that much space, with the folder and notebook still needing to fit behind it.
We recommended trying 30 × 38 × 15 cm instead. The extra depth would accommodate the box and document stack more comfortably, while the additional width would make the kit easier to pack. Simply making the original bag taller would not solve the problem at the base.
We explained the suggested arrangement to the client and recommended checking the revised dimensions with a finished sample before confirming production. The key checks were whether the folder could stay flat, the mug box could sit securely, and the contents could be removed without pulling against the sides.
This is why we review the complete packing requirements even when a client provides specific dimensions. The requested size is a useful starting point, but the items inside—and how they fit together—determine which size is most practical.
Check Handle Length and Printing Area
Handle Length vs Handle Drop
Handle length describes the length along the handle; a supplier may include attachment sections in that figure. Handle drop is the vertical distance from the top edge of the bag to the highest point of the raised handle.
These measurements are not interchangeable. Handle spacing and attachment design affect the available clearance, so confirm the intended hand-carry or shoulder-carry fit with a sample. For a tall bag, also check that it does not hang uncomfortably low when carried by hand.
Bag Size vs Printable Area
The full front panel is not automatically the available printing area. Seams, top hems, handle attachments, and printing equipment can limit where artwork fits.
Confirm the printable width and height on the chosen bag template before finalizing the logo layout. For larger or edge-to-edge artwork, discuss the production method early rather than assuming the design can be added to any finished bag.
Common Non-Woven Bag Sizing Mistakes
Treating outside dimensions as usable inside dimensions. Seams, binding, hems, and inserts can reduce the space available. A rigid box matching the bag’s listed measurements is not a reliable fit. Confirm the internal space or test the box directly.
Approving a bag for one item when the order contains several. A sample may suit one garment or brochure but fail once an accessory, gift box, or second purchase is added. Use the complete intended order for approval, including promotional extras.
Ignoring the opening and closure. An expanded base can appear large enough while the opening makes loading awkward. Check the narrowest usable point and make sure any zipper or flap functions without forcing the contents down.
Using the largest possible order to choose every bag. This can leave regular purchases looking lost inside oversized packaging. Compare your usual order combinations before deciding whether one flexible format or two distinct sizes will work better.
How Bag Size Affects Cost and Storage
Increasing bag dimensions generally increases fabric requirements when other specifications stay the same. However, price does not necessarily rise in direct proportion to the bag’s width, height, or calculated volume. The cutting layout, available fabric width, construction, and production quantity can all affect the quotation.
Ask for comparisons using the same material, handles, printing, and finish. Otherwise, a cheaper sample may reflect a different specification rather than a more efficient size. Where fit allows, a modest dimensional adjustment may improve material use, but the manufacturer needs to assess that against the actual production layout.
Larger folded bags may also require more storage space or change the number packed in each carton. Compare packed carton dimensions and quantities rather than assuming that an increase in carrying capacity produces an identical increase in shipping volume.
For retailers, one versatile size simplifies storage and replenishment. Two sizes can provide a better fit if purchases divide clearly into small gifts and bulkier goods. Choose based on real order patterns, and keep any occasional oversized purchases separate from the specification used for everyday orders.
What to Confirm When Ordering Custom Non-Woven Bag Sizes
Once the size looks suitable, record the details clearly so the approved sample and production specification describe the same bag.
| Item to confirm | What to record |
|---|---|
| Body dimensions | Width, height, depth, units, and measurement points |
| Bag construction | Flat, bottom gusset only, or side-and-bottom gusset construction |
| Contents | Packed product dimensions, quantity, orientation, and intended load |
| Handles | Length definition, handle drop, attachment, and carrying method |
| Artwork | Printable area, position, and final artwork dimensions |
| Fit approval | Results from loading the finished sample with actual products |
| Size tolerance | Agreed dimensional variation and how the finished bag will be measured |
Material choice should support the intended use. Our guide to what non-woven bags are made of explains the material background. If the project involves demanding loads or repeated heavy use, comparing non-woven bags and woven bags can help you consider alternative constructions.
For an EcoBagFactory custom bag project, a useful starting brief includes the packed product dimensions, a photo of the intended arrangement, and the preferred carrying method. These details provide a clearer basis for selecting a size than requesting a “medium” or “large” bag alone.
FAQs About Non-Woven Bag Sizes
What is the standard size of a non-woven bag?
There is no single standard size used by all suppliers. Dimensions such as 30 × 38 × 10 cm or 40 × 45 × 15 cm can serve as selection references, but the appropriate size depends on the bag construction and contents.
What size non-woven bag fits A4 documents?
A 25 × 35 × 10 cm portrait bag is a useful starting point for an A4 document pack. Measure folders and brochure stacks separately, and check the finished bag if you plan to include other items.
Does the height of a non-woven bag include its handles?
In this guide, height means the bag body only. Supplier conventions can differ, so confirm the measurement definition and request handle dimensions separately.
Can a flat non-woven bag hold boxed items?
It may hold a slim box if there is enough room, but the panels must wrap around the box’s thickness. For bulkier rigid packaging, a gusseted bag usually provides a more practical starting point. Test the actual box inside a sample.
Does a larger non-woven bag hold more weight?
Not necessarily. A larger bag offers more potential space, while load suitability also depends on the fabric, seams, handle attachment, and reinforcement. Confirm strength for the finished construction rather than estimating it from dimensions alone.
Can I order a size between small, medium, and large?
Custom dimensions can be developed around the intended contents, subject to construction and production requirements. Specify the measurements you need and verify the fit with a finished sample rather than relying on a size label.
