minecraft how far can tnt entity fall

In Minecraft, a TNT entity (which is created when TNT is ignited and turns into a falling, explosive entity) can fall a maximum distance of 80 blocks before it explodes due to the fall damage not affecting it, but rather the fuse running out.

However, if the TNT entity is falling and hits a solid block, or hits water, it will explode immediately.

The fuse time of TNT is 80 ticks (4 seconds) in Java Edition and 77-81 ticks (3.85-4.05 seconds) in Bedrock Edition, so if the TNT entity is falling and doesn’t hit anything, it will explode after this time, regardless of the distance it has fallen.

It’s worth noting that the height at which the TNT entity explodes due to the fuse running out can be affected by the server’s tick rate, which can cause some variation in the maximum fall distance.
