How the Artwork Checker works
Drop a logo or image into the checker and enter how large it will be printed on your box. The tool calculates the effective resolution in pixels per inch (ppi) at that size and compares it with the target for your print method:
Effective ppi = image width in pixels ÷ printed width in inches
| Print method | Target |
|---|---|
| Offset or digital on paperboard | 300 ppi |
| Large panels viewed at arm's length | 200 ppi |
| Flexo on corrugated | 150 ppi |
The checker also reports:
- Maximum print size at the target resolution
- Transparency (whether a PNG or WEBP has a transparent background)
- Color mode hints (CMYK JPEG, RGB or grayscale)
- A preview on kraft to show how the artwork looks on brown board
Vector files (SVG) are reported as vector: they scale to any size without losing quality. For AI, EPS and PDF files, include them with your quote and our team will check them for free.
Your files stay private
The checker runs entirely in your browser. Files are not uploaded to our servers.
What to do if your image fails
- Ask for the original vector logo (AI, EPS, SVG or PDF) from your designer.
- Use a larger source image or print it smaller.
- Have the logo redrawn as a vector; our design team can help.
- Avoid upscaling low-resolution images: it does not add detail.

Pixels needed for each printed width
Minimum image width in pixels for a given printed width at the common packaging targets. Divide your image width in pixels by the printed width in inches to find its effective resolution.
| Printed width | 300 ppi (offset, digital) | 200 ppi (large panels) | 150 ppi (flexo on corrugated) |
|---|---|---|---|
| 1 in | 300 px | 200 px | 150 px |
| 2 in | 600 px | 400 px | 300 px |
| 3 in | 900 px | 600 px | 450 px |
| 4 in | 1,200 px | 800 px | 600 px |
| 5 in | 1,500 px | 1,000 px | 750 px |
| 6 in | 1,800 px | 1,200 px | 900 px |
| 8 in | 2,400 px | 1,600 px | 1,200 px |
| 10 in | 3,000 px | 2,000 px | 1,500 px |
| 12 in | 3,600 px | 2,400 px | 1,800 px |
| 14 in | 4,200 px | 2,800 px | 2,100 px |
| 16 in | 4,800 px | 3,200 px | 2,400 px |
| 18 in | 5,400 px | 3,600 px | 2,700 px |
| 20 in | 6,000 px | 4,000 px | 3,000 px |
| 24 in | 7,200 px | 4,800 px | 3,600 px |
Vector logos (SVG, AI, EPS, PDF) scale to any size and are always preferred for logos and text.
Maximum print size for common image widths
How wide an image can print while meeting each resolution target.
| Image width | At 300 ppi | At 200 ppi | At 150 ppi |
|---|---|---|---|
| 500 px | 1.7 in | 2.5 in | 3.3 in |
| 800 px | 2.7 in | 4.0 in | 5.3 in |
| 1,000 px | 3.3 in | 5.0 in | 6.7 in |
| 1,200 px | 4.0 in | 6.0 in | 8.0 in |
| 1,500 px | 5.0 in | 7.5 in | 10.0 in |
| 2,000 px | 6.7 in | 10.0 in | 13.3 in |
| 2,400 px | 8.0 in | 12.0 in | 16.0 in |
| 3,000 px | 10.0 in | 15.0 in | 20.0 in |
| 4,000 px | 13.3 in | 20.0 in | 26.7 in |
| 6,000 px | 20.0 in | 30.0 in | 40.0 in |
Key terms on this page
- Artwork
- The final graphic files (logos, images, text and colors) placed on a dieline and used to make printing plates or digital print files.
- Resolution
- The detail in a raster image, measured in pixels per inch (ppi). Print usually needs 300 ppi at final size.
- Paperboard
- Thick paper (usually 0.010 inch or more) used for folding cartons, such as SBS, kraft and recycled board.
- Flexographic printing (flexo)
- A printing method using flexible relief plates and fast-drying inks, common on corrugated boxes, labels and flexible packaging.
- CMYK
- The four process ink colors (cyan, magenta, yellow and key/black) combined in small dots to reproduce full-color images in print.
- Kraft
- Paper or board made from unbleached wood pulp, naturally brown and strong.
- Board
- A general term for thick paper materials used in packaging, including paperboard, corrugated board and greyboard.
- Dieline
- A flat template showing the exact shape of a box before folding, with cut, crease, bleed and safe zones. Artwork is designed on top of it.

Frequently asked questions
What resolution do I need for packaging?
300 ppi at the final printed size for offset and digital printing on paperboard.
Is a PNG good enough for packaging?
A large PNG can work for images, but logos should be vector files whenever possible.
Why does my logo look fine on screen but fail here?
Screens display images at about 72–150 ppi. Print needs more detail at the printed size.
