Quick answer (at 3:2)
At 300 DPI a 24 MP image prints about 20.0 × 13.3 inches (50.8 × 33.9 cm) assuming a 3:2 aspect ratio.

How we calculate this
- Convert 24 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.
