PX to CM converter (pixels to centimeters)
Convert pixels to centimeters using DPI. This matters for print size; screens use pixels directly.
Conversion formulas
- cm = pixels ÷ DPI × 2.54
- pixels = cm ÷ 2.54 × DPI
- 1 inch = 2.54 cm
Common DPI values
- 72–96 DPI for screens
- 150 DPI for drafts
- 300 DPI for print
DPI affects print size, not screen display.
Quick examples
- 1200 px at 300 DPI → 10.16 cm
- 1080 px at 300 DPI → 9.14 cm
- 1920 px at 96 DPI → 50.8 cm
3 steps (using this tool)
- Pick your target DPI (print vs screen).
- Convert cm to pixels (or pixels to cm).
- Enter the pixel size in the resizer and export.
FAQ
How do I convert px to cm?
Use cm = pixels ÷ DPI × 2.54.
Quick tip: For print, 300 DPI is common; for screens use 72–96 DPI.
Common mistake: Skipping DPI—your physical size will be wrong.
Which DPI should I use?
300 DPI for print submissions, 72–96 DPI for screens.
Quick tip: Always follow the requirement if a DPI is specified.
Common mistake: Guessing DPI for official documents—can lead to rejection.
Does DPI improve image quality?
No. DPI doesn’t add pixels; it only changes print size.
Quick tip: Higher quality comes from more pixels, not a higher DPI value.
Common mistake: Expecting DPI to fix a low-res image.
Do you upload my images?
No. Processing happens locally in your browser. Your files are not uploaded.
What size should I use?
Use the recommended size.
Which export format should I use?
JPG for photos, PNG for text/logos or transparency, WebP for smaller files (if supported).
Crop vs Pad — what is the difference?
Crop fills the target size (may cut edges). Pad fits the whole image and adds background/space.
How do I protect text and logos?
Keep important content centered and avoid placing critical text at the edges.
Can I batch resize?
Yes. Use the Batch Resizer to apply the same size to many images.
