Estimate blast radius and volume for TNT, and how much dynamite a crater of a given size needs.
The calculator estimates the blast radius and destruction volume of TNT and works out how much dynamite a crater of a given size needs.
One caveat matters: an exact result depends on each block's blast resistance, and stone, dirt and obsidian differ enormously. So this is an estimate, not a guarantee.
A single TNT destroys soft blocks roughly 4 blocks out. Chain explosions do not add up linearly — there is an 80-tick delay between them.
Enter how many TNT blocks are placed at once.
Set the crater radius you want.
Read the estimated blast radius and how much dynamite is needed.
Verify in a test world — the real crater depends on block types.
The game computes damage per block based on its resistance and distance from the epicentre. An averaged model cannot capture that precisely.
No. Both have very high blast resistance and survive ordinary TNT.

Estimates only: the real crater depends on block types and how the TNT is placed.
One TNT destroys soft blocks within roughly 4.2 blocks (except obsidian and bedrock).
Point-blank TNT damage to a player is about 65 HP (32.5 hearts).
