Bedrock Depth in Different Minecraft Versions
In modern Minecraft (Java Edition 1.18+), bedrock generates at the very bottom of the world at Y-level -64. This represents the absolute floor of your Minecraft world, below which you cannot dig or build.
Legacy Versions vs Current Versions
Before the Caves & Cliffs update, bedrock appeared much higher up. In older versions (pre-1.18), bedrock typically generated between Y-levels 0 to 5, with the thickest concentration at Y-level 1. The world height was also much more limited back then.
Bedrock Layer Characteristics
Bedrock doesn’t form a perfectly flat surface. Instead, it creates an irregular layer that’s typically 1-5 blocks thick. The topmost bedrock blocks can appear as high as Y-level -60, while the bottom layer sits firmly at Y-level -64. This uneven distribution means some areas have thin spots while others are completely solid.
Why Bedrock Depth Matters for Mining
Understanding bedrock depth helps optimize your mining strategy. Diamond ore generates most frequently between Y-levels -50 to -64, meaning you’ll often encounter bedrock while diamond mining. Many players dig down to bedrock level and then mine upward to maximize their diamond yield while using the bedrock as a reference point.
Nether and End Bedrock
The Nether has bedrock at both the top (Y-level 127) and bottom (Y-level 0) of the dimension. The End features bedrock platforms and pillars at various heights, but the main island sits on bedrock at Y-level 0.
Whether you’re planning deep mining expeditions or building massive underground bases, knowing that bedrock sits at Y-level -64 helps you navigate Minecraft’s depths more effectively.
TL;DR
Bedrock generates at Y-level -64 in modern Minecraft, forming the unbreakable bottom layer of the world. In older versions, it appeared much higher at Y-levels 0-5.
