Spawn Proofing Calculator
Find how far apart to place torches so no hostile mob can spawn, using the exact block-light rule from Java Edition.
Source light level
14
Safe radius (taxicab)
13
Max square spacing
13
Max staggered spacing
18
Floor Light Coverage
Top-down view of a 25×25 floor with one light source at the center. Adjust the spacing above to see gaps appear once you space sources farther apart than the max safe spacing.
Safe (block light ≥ 1)
Unsafe (block light 0)
Light source
Coverage: 100%
All Light Sources (Modern 1.18+ rule)
| Source | Light level | Safe radius | Square spacing | Staggered spacing |
|---|
Uses the real vanilla taxicab (Manhattan) light-falloff rule: light drops by exactly 1 per block of |dx|+|dz| distance from the source. Multi-torch grid spacing assumes a single consistent light source type placed at every grid point — mixing source types or accounting for ceiling height/other obstructions isn’t modeled here.
