📋 Why These Specific Sizes? - Technical Deep Dive

🎯 A4 Paper Optimization

Both grid systems are engineered around standard A4 paper (210×297mm). Each tile is sized at 190×277mm to fit comfortably with 1cm margins on all sides, ensuring clean printing without edge cutoffs on any consumer printer.

📐 150 DPI Standard

The 150 DPI resolution is the sweet spot for tabletop gaming:

  • Perfect Grid Squares: 25mm squares = exactly 147.6 pixels at 150 DPI
  • Miniature Compatibility: Standard 28-32mm miniatures fit perfectly
  • Print Quality: Crisp details without massive file sizes
  • Processing Speed: Fast web browser handling without memory issues
📏 Grid Dimensions Explained

2×3 Grid (57×55cm): Based on average tabletop space and typical encounter sizes. Six A4 sheets create a substantial play area without overwhelming smaller tables.

3×3 Grid (57×83cm): 50% taller format accommodates corridor-heavy dungeons and outdoor scenes that need more vertical space for natural exploration flow.

🔢 Pixel Mathematics
  • Tile Size: 190mm × 277mm = 1122 × 1638 pixels at 150 DPI
  • 2×3 Total: 3 tiles × 1122px = 3366px wide, 2 tiles × 1638px = 3276px tall
  • 3×3 Total: 3 tiles × 1122px = 3366px wide, 3 tiles × 1638px = 4914px tall
  • Margin Addition: Each tile gets 1cm (59px) margins added during export
✅ Output Quality Guarantee

When you print the generated tiles at 100% scale on A4 paper, your assembled map will have perfectly aligned grid squares that measure exactly 25mm - the international standard for tabletop miniatures.
