Comprehensive analysis of DPI (Dots Per Inch) correlation with pixel dimensions for optimal RRB signature compliance. Technical reference matrix displaying exact dimensional calculations and estimated file size parameters across multiple resolution settings:
⚠️ Technical File Size Considerations:
File size estimations reflect signature complexity variables and compression optimization. Actual output may vary based on:
- Content Complexity: Minimalist signature designs = reduced file sizes
- Background Optimization: Clean backgrounds enable superior compression efficiency
- Compression Algorithms: Intelligent JPEG optimization for RRB compliance standards
- Signature Characteristics: Handwritten content compression varies with design complexity
Example: Simplified monochrome signatures may achieve 10-15 KB at 200 DPI, while complex multi-element designs could range 30-45 KB.
| DPI | Width (pixels) | Height (pixels) | Total Pixels | Est. JPEG Size Range | RRB Compliance |
|---|---|---|---|---|---|
| 96 DPI | 132 px | 75 px | 9,900 | 8-20 KB Simple: 8-12 KB Complex: 15-20 KB |
❌ Too Small |
| 200 DPI | 276 px | 157 px | 43,332 | 10-45 KB Simple: 10-18 KB Complex: 25-45 KB |
✅ Perfect |
| 300 DPI | 413 px | 236 px | 97,468 | 25-80 KB Simple: 25-40 KB Complex: 50-80 KB |
⚠️ May Be Too Large |
| 600 DPI | 827 px | 472 px | 390,344 | 100-300 KB Simple: 100-150 KB Complex: 200-300 KB |
❌ Way Too Large |
💡 Pro Tips for RRB Signatures:
- 200 DPI is Optimal: Provides the perfect balance between quality and file size for RRB requirements.
- Target 30-49 KB: RRB specifically requires signature files to be between 30-49 KB in size.
- Minimum 140×60 pixels: Ensure your signature meets the minimum resolution requirements.
- JPEG Format: Always save as JPG/JPEG format as required by RRB portals.
- White Background: Ensure your signature has a clean white background for best results.
