DPI (dots per inch) defines how many pixels you need to fill one inch of paper. At 300 DPI, a 10×8 inch print needs 3000×2400 pixels. StudioSizer calculates this automatically and outputs exact pixel sizes.
Common conversions
- 8×10 in @300 DPI → 2400×3000 px
- 24×36 in @300 DPI → 7200×10800 px
- 50×70 cm @300 DPI → ≈5906×8268 px
With StudioSizer, pick a Preset or enter custom inches/cm and export up to 10 sizes per image.
