Pixel sind meist ganzzahlig, Dezimalstellen sind für feine Berechnungen zulässig.
Geben Sie die Größe ein – das Pixelfeld wird sofort aktualisiert.
Sie benötigen die Pixeldichte (PPI). Ein Zoll = 2,54 cm. Formeln:
cm = pixels ÷ PPI × 2.54 pixels = cm ÷ 2.54 × PPI Beispiele: bei 96 PPI sind 100 px ≈ 2.65 cm. Bei 300 PPI sind 100 px ≈ 0.85 cm.
PPI ist für digitale Bilder, DPI für Drucker. Nutzen Sie PPI für Größenberechnungen.
Für Web-Bilder ja. Für den Druck benötigen Sie meist höhere Dimensionen.

A pixel (px) is the smallest addressable element of a raster image displayed on a screen. The word "pixel" is a combination of "picture" and "element." Each pixel represents a single point of color, and millions of pixels together form the images you see on monitors, phones, and tablets.
Pixels have no fixed physical size — their real-world dimensions depend on the display's pixel density (PPI). A pixel on a 27-inch 1080p monitor is physically larger than a pixel on a 6-inch smartphone with the same resolution.
Key fact: A standard web display uses 96 PPI, meaning each pixel is approximately 0.0265 cm (0.265 mm) wide.
A centimeter (cm) is a metric unit of length equal to one hundredth of a meter. It is widely used around the world for everyday measurements — from paper sizes (A4 is 21 × 29.7 cm) to screen dimensions and print layouts.
Unlike pixels, centimeters represent a fixed physical size. When designers and print professionals need to specify how large an image will appear on paper or in the physical world, they use centimeters (or inches). Converting between pixels and centimeters requires knowing the resolution (PPI) of the output device.
Key fact: 1 inch = 2.54 cm. This constant is the bridge between pixels (digital) and centimeters (physical).
DPI (Dots Per Inch) measures how many ink dots a printer places within one linear inch. Higher DPI means finer detail and smoother prints. Common print DPI values include 150 (draft), 300 (standard quality), and 600+ (high-quality or photo prints).
While DPI is often used interchangeably with PPI, they are technically different. PPI (Pixels Per Inch) refers to digital screen resolution, while DPI refers to printer output. For pixel-to-cm conversion, PPI is the correct value to use.
PPI (Screens)
72, 96, 150, 200, 300 PPI
DPI (Printers)
150, 300, 600, 1200 DPI
The conversion between pixels and centimeters uses a straightforward mathematical formula based on the pixel density (PPI):
cm = (pixels / PPI) × 2.54 pixels = (cm / 2.54) × PPI Step-by-step example: Convert 500 pixels to cm at 96 PPI:
A pixels to cm conversion table provides quick, pre-calculated results so you don't need to do the math yourself. Each row shows a pixel value and its equivalent in centimeters at a specific PPI. Below is a multi-PPI comparison table for the most commonly used pixel values:
| Pixels | 72 PPI | 96 PPI | 150 PPI | 300 PPI |
|---|---|---|---|---|
| 50 px | 1.76 cm | 1.32 cm | 0.85 cm | 0.42 cm |
| 100 px | 3.53 cm | 2.65 cm | 1.69 cm | 0.85 cm |
| 200 px | 7.06 cm | 5.29 cm | 3.39 cm | 1.69 cm |
| 500 px | 17.64 cm | 13.23 cm | 8.47 cm | 4.23 cm |
| 1000 px | 35.28 cm | 26.46 cm | 16.93 cm | 8.47 cm |
| 1920 px | 67.73 cm | 50.80 cm | 32.51 cm | 16.26 cm |
| 3840 px | 135.47 cm | 101.60 cm | 65.02 cm | 32.51 cm |
How to read this table: Find your pixel value in the left column, then look across to the PPI column that matches your display or print setting. The intersection gives you the physical size in centimeters.
Common screen resolutions and their physical dimensions at 96 PPI (standard web display):
| Resolution (px) | Width (cm) | Height (cm) |
|---|---|---|
| 1200 × 1600 | 31.75 | 42.33 |
| 1024 × 1536 | 27.09 | 40.64 |
| 1080 × 1350 | 28.58 | 35.72 |
| 3024 × 4032 | 80.01 | 106.68 |
| 1920 × 1080 | 50.80 | 28.58 |
| 3464 × 3464 | 91.65 | 91.65 |
| 1600 × 400 | 42.33 | 10.58 |
| 431 × 531 | 11.40 | 14.05 |
| 2550 × 3300 | 67.47 | 87.31 |
| 3840 × 2160 | 101.60 | 57.15 |
Note: These dimensions change with PPI. At 300 PPI (print), the same 1920×1080 image would only be 16.26 × 9.14 cm.
The pixel-to-centimeter ratio varies depending on the PPI setting. Here's a quick reference for the most common PPI values:
The higher the PPI, the more pixels fit into each centimeter — resulting in sharper, more detailed images.
