Minecraft worlds are extremely large, measuring about 60 million blocks wide and 60 million blocks long, which equals approximately 3.6 trillion square blocks. If each block is one meter by one meter, the world spans about 60,000 kilometers across, which is roughly one and a half times the Earth's circumference. This makes the Minecraft world over 24 times larger than all the land surface on Earth combined. Additionally, Minecraft worlds have a vertical height of 384 blocks, making the three-dimensional space vast for exploration and creation.
