Custom sticker printing can use different measurements depending on the printer, sticker shape and finishing method. An open size generally refers to the full flat artwork or layout dimension before the sticker is cut into its final shape, helping printers set up the design and cutting correctly.
What does “open size” mean in custom sticker printing?
In custom sticker printing, an open size usually describes the complete flat dimensions of the artwork or layout before the final sticker shape is cut. It gives the printer the measurements needed to prepare the artwork, cutting line and print area correctly.
The term can vary between printers, so always confirm how they define “open size” before submitting artwork.
For example, imagine you want a rectangular sticker that will be folded around a small product package. The visible front section might be one measurement, while the complete unfolded artwork covers a larger area.
Open size vs finished size
These two measurements serve different purposes:
| Measurement | Meaning | Main purpose |
|---|---|---|
| Open size | Full flat artwork/layout dimensions | Artwork and production setup |
| Finished size | Final dimensions after cutting | Actual sticker size |
| Bleed size | Artwork extending beyond the cut line | Prevents unwanted white edges |
| Safe area | Space kept inside the cut line | Protects important text and logos |
Why this matters: Confusing open size with finished size can cause artwork to be too large, too small or incorrectly positioned when printed and cut.
Why are open sizes used for stickers?
Open sizes help printers understand the complete artwork area before cutting, positioning and finishing the sticker. This becomes especially useful when a sticker has multiple panels, wraps around a surface or requires a specific cutting arrangement.
1. They help prepare the artwork
A printer needs accurate dimensions to position logos, text, graphics and other design elements.
Providing the correct open size gives the production team a reliable starting point.
2. They help define the cutting area
Custom stickers can be produced as circles, squares, rectangles, ovals, custom shapes and irregular die-cut designs.
The open artwork needs to correspond correctly with the intended cutting line.
3. They reduce production errors
Incorrect measurements can result in:
- Cropped artwork
- Misaligned designs
- Text too close to the edge
- Incorrect proportions
- Uneven borders
- Poorly positioned logos
- Extra material around the design
4. They make custom shapes easier to produce
A standard rectangle is relatively straightforward. A custom die-cut sticker requires a more precise relationship between the artwork and the cut path.
Expert insight: For custom-shaped stickers, the cutting outline should be treated as part of the production specification rather than simply an outline added for visual effect.
What is the difference between open size and sticker finished size?
The finished size is the final physical size of the sticker, while the open size represents the larger flat artwork or layout used during production when applicable.
For a simple single-piece sticker, these measurements may be very close or the printer may only request the final size. For more complex applications, the open size can be different.
Example of sticker measurements
Suppose a business wants a rectangular product sticker with a finished size of 80 × 50 mm.
The artwork might require additional bleed around the cutting edge. If the printer requests a larger working area, the supplied artwork could therefore be larger than the final 80 × 50 mm sticker.
A simplified setup could look like this:
- Finished sticker: 80 × 50 mm
- Bleed: 2–3 mm, depending on printer specification
- Artwork area: Larger than the final cut size
- Cut line: Defines the final 80 × 50 mm shape
[Citation/source should be added here if publishing technical print specifications.]
The exact bleed requirement should always follow your printer’s artwork guidelines rather than using one universal measurement.
How do you measure an open size for stickers?
Measure the complete flat artwork area required for production, then check the printer’s specification for bleed, trim and cutting requirements.
Use this process before sending your design to print.
Step 1: Decide the final sticker dimensions
Start with the size you want customers to receive.
For example:
- 50 × 50 mm
- 75 × 50 mm
- 100 × 50 mm
- 100 × 100 mm
Your choice should depend on where the sticker will be applied and how much information it needs to display.
Step 2: Identify the cutting shape
Decide whether the sticker will be:
- Square
- Rectangle
- Circle
- Oval
- Rounded rectangle
- Custom die-cut
- Irregular shape
The more complex the shape, the more carefully the cutting path needs to be prepared.
Step 3: Add the required bleed
Bleed allows the background artwork to extend beyond the final cut line.
This helps prevent a thin unwanted white edge caused by small cutting variations.
A common industry practice is around 2–3 mm of bleed, but the correct amount depends on the printer’s production requirements.
Step 4: Keep important content inside the safe area
Don’t place important text, QR codes or logos directly against the cutting line.
Keep essential design elements comfortably inside the finished sticker boundary.
Step 5: Confirm the printer’s open-size specification
This is the step many businesses overlook.
Different printers can use terminology differently. Before uploading artwork, check whether the requested dimensions refer to:
- Finished size
- Open size
- Artwork size
- Bleed size
- Cut-line size
- Sheet size
- Roll label dimensions
Why this matters: A technically correct design can still be unsuitable for production if it follows the wrong measurement definition.
What sticker sizes work best for businesses?
The best sticker size depends on the application, available surface area, branding requirements and amount of information the sticker must display.
There is no single ideal size for every business.
| Sticker use | Practical size examples |
| Small logo stickers | 30–50 mm |
| Product branding | 50–80 mm |
| Packaging labels | 50–100 mm |
| Promotional stickers | 75–120 mm |
| Shipping or information labels | 75–150+ mm |
| Large promotional graphics | 150 mm+ |
These are practical examples rather than fixed industry rules.
Small stickers
Small stickers work well for:
- Cosmetic packaging
- Small boxes
- Gift packaging
- Product seals
- Brand logos
- Promotional giveaways
However, small dimensions limit how much text you can use.
Medium stickers
Medium-sized stickers provide more space for:
- Brand names
- Product information
- Website addresses
- QR codes
- Promotional messages
- Social media details
They are often a useful choice for retail and eCommerce packaging.
Large stickers
Large stickers are suitable when visibility matters more than compact branding.
Examples include:
- Shop windows
- Promotional displays
- Storage containers
- Larger product packaging
- Event promotions
How does sticker shape affect open size?
Sticker shape affects how artwork and cutting lines are prepared, particularly when the sticker uses a custom die-cut shape.
A circle may only require a simple diameter measurement. A complex die-cut sticker may need a carefully prepared vector cutting path.
Standard shapes
Standard shapes are generally easier to specify:
- 50 × 50 mm square
- 80 × 50 mm rectangle
- 60 mm circle
- 100 × 70 mm oval
Custom die-cut stickers
Custom shapes can follow:
- Logos
- Characters
- Product silhouettes
- Illustrations
- Brand symbols
- Special promotional designs
For these designs, the cutting path needs to be clear and accurately positioned.
Expert insight: If your sticker follows the shape of a logo, don’t assume that the visible artwork boundary automatically becomes the production cut line. The printer may require a separate vector cut path.
What artwork file should you use for custom sticker printing?
Vector artwork is usually the safest choice for logos, text and custom cutting paths because it can maintain clean edges at different sizes.
Common professional artwork formats can include:
- AI
- EPS
- SVG, where supported
- High-resolution PNG or JPEG for suitable artwork
The exact accepted format depends on the printer.
What about resolution?
Raster images should normally be supplied at an appropriate print resolution.
A commonly used professional print standard is 300 DPI at the intended output size, although the correct specification depends on the artwork and production method.
[Citation/source should be added here if publishing a specific technical resolution requirement.]
Don’t enlarge a small web image and expect it to produce the same quality as professionally prepared print artwork.
What mistakes should you avoid when setting sticker sizes?
The most common sticker-size mistakes involve confusing finished dimensions with artwork dimensions, forgetting bleed and placing important content too close to the cut line.
Avoid these seven problems:
- Using the wrong measurement
- Confirm whether the printer wants finished or open size.
- Forgetting bleed
- Extend background artwork beyond the cutting line when required.
- Putting text on the edge
- Keep important information inside the safe area.
- Using low-resolution images
- Low-quality artwork can appear blurry when printed.
- Ignoring the sticker shape
- Custom die-cut designs need accurate cutting information.
- Scaling artwork incorrectly
- Check that the document dimensions match the intended physical size.
- Skipping a final proof check
- Review spelling, dimensions, colours, logos and positioning before production.
How can businesses choose the right sticker size?
Choose the sticker size by starting with its purpose rather than choosing a dimension first.
Ask what the sticker needs to accomplish.
For branding
If the sticker mainly displays a logo, a smaller size may be enough.
For product information
Choose a larger format if you need ingredients, instructions, contact information or other details.
For promotions
A larger sticker can provide stronger visual impact, particularly when used on packaging, displays or promotional materials.
For QR codes
Make sure the QR code remains large enough to scan reliably and has sufficient contrast and clear space around it.
Why this matters: A sticker should remain readable at its actual physical size. A design that looks excellent on a computer screen may become difficult to read after being reduced for printing.
Is custom sticker printing suitable for product packaging?
Yes, custom sticker printing is widely useful for product packaging because stickers can add branding, information, promotional messages and finishing details without requiring completely custom-printed packaging.
Businesses can use stickers for:
- Product branding
- Logo application
- Packaging seals
- Tamper-evident applications
- Promotional campaigns
- Seasonal packaging
- Product variants
- QR codes
- Barcode labels
- Thank-you messages
- Limited-edition products
This can be particularly useful for small businesses that want professional packaging without committing to large quantities of fully printed boxes.
How much does custom sticker printing cost?
Custom sticker printing costs depend on factors such as size, quantity, material, shape, printing method and finishing.
Larger quantities can often reduce the effective cost per sticker, while complex shapes and premium materials can increase production costs.
Key pricing factors include:
| Factor | Potential effect |
| Quantity | Larger runs can reduce unit cost |
| Size | Larger stickers use more material |
| Shape | Complex die-cutting can add production requirements |
| Material | Premium or specialist stocks may cost more |
| Finish | Special finishes can increase the price |
| Colour coverage | Heavy ink coverage can affect production |
| Turnaround | Faster production may affect pricing |
For an accurate quotation, provide the printer with the finished size, quantity, material preference, shape and artwork requirements.
