Formula
Centimeters to pixels at 300 DPI converts metric measurements to pixels by first converting to inches, then multiplying by 300. For metric-based design, 1 cm = 0.393701 inches, so pixels = cm × 0.393701 × DPI. At 300 DPI, 1 cm = 118.11 pixels. This converter is essential for designers working with A4 (21×29.7 cm), A3, and other ISO paper formats.
px = cm × (DPI ÷ 2.54)cm = px ÷ (DPI ÷ 2.54)How to convert
- Measure in centimeters: Note your design dimensions in cm.
- Convert using the formula: px = cm × 300 ÷ 2.54, or approximately cm × 118.11.
- Apply to your export settings: Set the pixel dimensions in your design software for print-ready output.
