Quick answer (at 3:2)
At 300 DPI a 6 MP image prints about 10.0 × 6.7 inches (25.4 × 16.9 cm) assuming a 3:2 aspect ratio.

How we calculate this
- Convert 6 MP to approximate pixels for an aspect ratio.
- Divide each pixel dimension by DPI → inches:
inches = pixels ÷ DPI. - Convert inches to centimeters:
cm = inches × 2.54.
