How the Pixel to CM Calculator works

Pixels are a digital unit; centimeters are a physical unit. To relate them, we use DPI (dots per inch). This calculator assumes a common screen density of 96 DPI. With that assumption:

  • 1 inch = 2.54 cm
  • 1 inch = 96 px
  • So 1 px = 2.54 / 96 ≈ 0.026458 cm
  • And 1 cm ≈ 96 / 2.54 ≈ 37.80 px

How to use the Pixel (X) ⇄ CM calculator

  1. Choose direction using the ⇅ button (Pixel → CM or CM → Pixel).
  2. Enter your value in the From box.
  3. The To value updates instantly—no need to press Convert.
  4. Use the Clear button to reset both fields.

Actual printed or on-screen size may differ if your device or document uses a different DPI.

Pixel (X) to Centimeter Conversion Table

Approximate values at 96 DPI:

Pixels (px) Centimeters (cm)
10 px0.26 cm
50 px1.32 cm
100 px2.65 cm
200 px5.29 cm
500 px13.23 cm
1000 px26.46 cm

How to Convert Pixel (X) to Centimeter

Use the formula:

  • cm = pixels × 2.54 ÷ DPI
  • With 96 DPI: cm = pixels × 2.54 ÷ 96
  • pixels = cm × DPI ÷ 2.54

How many pixels is 1 cm?

At 96 DPI, 1 cm ≈ 37.80 px.

What is 3.5 cm × 4.5 cm in pixels?

Using 96 DPI: 3.5 cm ≈ 132 px, 4.5 cm ≈ 170 px. So ID/passport style 3.5 × 4.5 cm is about 132 × 170 px.

What is 1920×1080 resolution in cm?

At 96 DPI: 1920 px ≈ 50.80 cm, 1080 px ≈ 28.58 cm. Real size will change if your monitor has a different DPI.

How much is 50 px in cm?

FAQs

Does this calculator assume 96 DPI?
Yes. For consistency, pixeltocm.com uses 96 DPI as a standard screen reference. If your device or design uses a different DPI, apply the same formulas with your DPI value.
Can I adapt this for 300 DPI print?
Absolutely. For 300 DPI: cm = px × 2.54 ÷ 300. For example, 900 px at 300 DPI is 900 × 2.54 ÷ 300 ≈ 7.62 cm.
Why do different screens give different physical sizes?
Because actual DPI changes between monitors, laptops, and mobiles. Pixels are fixed units in your image; centimeters depend on device pixel density.
Is this tool suitable for UI, web, and print designers?
Yes, it is ideal for estimating sizes for layouts, mockups, and basic print planning, as long as you apply the correct DPI for your target medium.
