Precomputed values for a single standard TNT charge.
Blast values
- Max radius (air)
- 6.9
- Stone depth
- 2.05
- Safe distance
- 8
Blast behavior follows Java explosion mechanics; chain reactions multiply the area.

FAQ
FAQ
How big is a TNT explosion?
TNT has explosion power 4, reaching about 6.9 blocks in open air.
How deep does TNT dig into stone?
Against stone, the crater reaches roughly 2 blocks deep per charge.
How far should I stand?
8 blocks is a comfortable safe distance for standard TNT; chain reactions need more.
Does water stop TNT?
Yes: water absorbs explosions and prevents block destruction, a common mining technique.
Why does my crater look different?
The actual shape varies with obstacles, density and blast resistance of surrounding blocks.
