Plan any Minecraft build block by block, from spheres and spiral stairs to farms and pixel art. Bring in your own structures, and look up every item, mob and mechanic in the game.
Tap a block to highlight where it goes.
| Lap | Heights | Center |
|---|
Where each ore shows up in the Overworld, from bedrock at Y −64 to the build limit at Y 320. The wider the shape, the more of that ore there is at that height. These are the world generation rules used since the Caves and Cliffs update (1.18).
| Ore | Found between | Best Y | Pickaxe | Good to know |
|---|
Nether ores spread evenly through most of the height, except ancient debris, which is most common low down.
Numbers are for a normal world. Big updates sometimes change world generation, so check the Minecraft Wiki if something doesn't match your version.
Quick numbers worth knowing while you build, travel and farm.
Every item in the game. Search, then click one to see how to make it, how to get it, and what it’s used to make. Data from Java Edition .
The icons are simple drawings colored by what each item is made of, not the game’s own pictures.
The best enchantments for each piece of gear, and the full list with what clashes with what.
Which workstation gives which job, and every trade each villager can offer.
What each animal eats, and how to tame the ones you can.
Health, where they show up, what they drop, and how to handle them.
Structures worth finding, where they are, and the best loot in each.
How long each fuel lasts, and everything you can smelt.
What each redstone part does, the logic gates, and handy circuits.
Throw an eye of ender from two different spots, type in where you stood and which way it flew, and this works out roughly where the stronghold (and its End portal) is.
Angle is the first number after "Facing" on the F3 screen, with your crosshair on the floating eye. For example, in "Facing: south (Towards positive Z) (-31.5 / 12.0)" it's −31.5.
Stand still, throw an eye, and put your crosshair right on it while it hovers. Press F3 and note your X, Z and the angle (the first number in "Facing").
Walk at least 300 blocks at a right angle to the way the eye flew, not toward it. The wider the gap, the sharper the answer.
Do the same from the new spot. Type both readings in above.
Head to the spot shown, throw one more eye near it, and dig down where the eye drops straight down. Strongholds are underground.
For far strongholds, build a portal at the Nether coordinates shown (one eighth of the distance) and travel there instead.
Each eye has a 1 in 5 chance of breaking, so bring spares. In a normal world the 3 closest strongholds are between 1,280 and 2,816 blocks from 0, 0.
Walk to the spot shown and throw again. Keep following the eye. When it flies down into the ground instead of up and away, you’re standing over the stronghold.
Press F3 + G to show chunk borders. The eye leads to the chunk that holds the stronghold’s first staircase, so stand in the chunk where the eye dips down.
The staircase is always at block 4, 4 inside its chunk. On the F3 screen, the "Chunk" line starts with your spot inside the chunk; walk until it reads 4 and 4 (the middle number is height). Or use the helper below.
Never dig straight down. Dig a staircase, one block down for each block forward, so you can see what’s below you and walk back up. Keep a water bucket ready for lava.
Stone bricks (plain, mossy or cracked), iron doors and wooden doors mean you’ve hit it. If a stone block breaks oddly fast and a silverfish pops out, that’s a stronghold too.
Strongholds sit deep, so keep going down. Once you’re well below where you expected it, dig short tunnels out in each direction; strongholds are big, so you’ll cut into a corridor.
The portal room is usually away from the first staircase. Listen for the silverfish spawner and look for stairs up to a platform over lava. Put torches on your right-hand wall so you can always find your way back.
Type where you’re standing when the eye flies down. This gives the 4, 4 block of that chunk.
Bring at least 12 eyes of ender, a few extra for throws (each has a 1 in 5 chance of breaking), a good pickaxe, torches, food, a water bucket and some blocks. Silverfish hide in stone bricks: kill them with one hit, and don’t break blocks around you while they’re about, or more will join in.
Turn Overworld coordinates into Nether ones and back, and check that your portals will link to the right partner.
Pick an item and the enchanted books you have. This finds the cheapest order to combine them, so you spend the fewest levels and never hit "Too Expensive!".
Type your world seed and where you are. Green squares are slime chunks, where slimes spawn underground. Click any chunk to move there.
How filling every food is, from the game's own numbers. Click a column to sort.
How many experience points you need between levels, how much it takes for Mending to fix your gear, and roughly how much farming that is.
What to bring and how to win against the Ender Dragon, the Wither and Elder Guardians, and how to stay away from the Warden.
Plan a wall of maps that join up with no gaps, at any map scale. It works out which maps you need, where to stand to make each one, and how to hang them.
What every potion does, how to brew it, and how long it lasts. Open a section below. Java Edition, 1.21 and later.
Durations are for drinking. Longer means brewed with redstone, stronger means brewed with glowstone. You can't do both to one potion, and a dash means that version doesn't exist.
A longer or stronger potion stays longer or stronger when it turns, so long Night Vision becomes long Invisibility and Healing II becomes Harming II.
