Minecraft Beacon Calculator

A full level-4 beacon needs 164 mineral blocks (81 + 49 + 25 + 9). Levels 1, 2 and 3 need 9, 34 and 83.

Mineral type does not change the powers. This selection estimates crafting the entire base from one material, at 9 raw items per block.

Inventory comparison mode

Usable mineral blocks total (optional)

(?)

Enter whole, full base blocks reserved for this entire base. The comparison stays against the full base even after checking layers. It excludes beacon blocks, activation items and loose raw items. The selected material above controls only the hypothetical single-material crafting estimate.

Already built part of this pyramid?

Already-built level in this same layout

(?)

Keep the beacon tops at their current positions. Add larger layers underneath the existing base; clear or excavate enough space below. Reuse assumes the same layout. Reserved inventory is separate from placed blocks.

Will the range cover your area?

(?)

Place several beacons so their horizontal squares cover a circle or rectangular area. The pyramid level above sets the reach.

Optional. Enter the north-west block of the area, or leave both blank for positions relative to that corner.

These positions are separate beacon sites. Their beacon blocks and bases are not included in the materials above. Plan materials for each site separately.

Want a coloured beam?

Glass above the beacon, bottom to top

(?)

The lowest glass sets the beam’s colour. Each glass above it is mixed half and half with the colour below, so the top glass counts most. Stained glass panes work the same; clear glass changes nothing. This plan puts the same glass above every beacon. Colours follow Java Edition.

(?)

Structure files hold the whole pyramid with its beacons and any glass above them, so a mod or a structure block can show or place it for you. They are made in your browser and never uploaded.

Java with the Litematica mod: put the .litematic file in the schematics folder inside your .minecraft folder. In the game, press M, choose Load Schematics, select the file and load it. It appears where you stand as a see-through guide to build along.

Bedrock: in a Creative world with cheats on, get a structure block with this command:

/give @s structure_block

Set the structure block to Load, press Import, choose the .mcstructure file, then press Load. Import is only on Windows. A structure block loads at most 64 × 64 blocks across and 384 high, and the empty cells keep whatever is already in your world.

Build it layer by layer

(?)

Fill every layer. Each new layer sits on the one below, centred with a one-block inset on all four sides.

Checks record base construction only. They do not confirm a working beacon in the game. Bring the beacon blocks and activation items separately, then check the beam and powers in your world. Plans are saved by base size on this browser; changing the crafting material keeps your checks and stock.

Building at exact game coordinates?

Use world coordinates

(?)

Enter the block where the north-west beacon goes: the beacon itself, not the base under it. East is +X, south is +Z. Each layer then shows its Y level and its X and Z range, and the range question shows where the effect reaches.

Placed the beacons on top?

(?)

These are your manual records. Base checks never activate a beacon or verify game success. At level 4, each beacon chooses either its primary effect at level II, or a primary effect at level I plus Regeneration. Bring one iron ingot, gold ingot, emerald, diamond or netherite ingot per beacon for the initial selection.

How many blocks does a full beacon need in Minecraft?

A full, four-level pyramid for one beacon needs 164 mineral blocks — 2 stacks + 36. If you use only iron, that is 1,476 iron ingots. These totals cover the solid base only; bring the beacon block and the item used to activate its powers separately.

Single-beacon base materials by pyramid level

Single-beacon base materials by pyramid level
Level	Layers, bottom to top	Base blocks	Iron ingots, if all iron
1	3×3	9	81
2	5×5 + 3×3	34	306
3	7×7 + 5×5 + 3×3	83	747
4	9×9 + 7×7 + 5×5 + 3×3	164	1,476

Each layer is filled, not hollow. Add the area of every layer to get the base block count: 81 + 49 + 25 + 9 = 164 for level 4. Multiply by 9 to convert iron blocks to iron ingots. Other material choices keep the same block count.

How do you make a beacon in Minecraft?

Craft it from 5 glass, 3 obsidian and 1 nether star. The nether star drops when you defeat the Wither.

Then build a solid pyramid of iron, gold, emerald, diamond or netherite blocks: one 3×3 layer for level 1, up to four layers and 164 blocks for level 4. Place the beacon on the centre of the top layer with a clear view of the sky; glass above it is fine.

Open the beacon and put in one iron ingot, gold ingot, emerald, diamond or netherite ingot to choose its powers.

Choose the pyramid level

Can you use copper blocks for a beacon base?

No. Only blocks of iron, gold, emerald, diamond and netherite count, and copper blocks are not one of them. You can mix those five in any layer; the material changes neither the powers nor the range.

Count a base of mixed blocks

How do you change the beacon beam colour?

Put stained glass or stained glass panes in the beam above the beacon. The lowest glass sets the colour, and each glass above it is mixed half and half with the colour below, so the top glass counts most. Clear glass changes nothing.

The beam colour question in this calculator builds the stack for you: add glass to see the colour, or pick a colour and let it find the glass. It uses Java Edition’s colours.

Find the glass for a colour

Where exactly do I build it?

Stand where the north-west beacon will go and read your block position: press F3 in Java Edition, or turn on Show Coordinates in Bedrock Edition. Enter that X, Y and Z under “Building at exact game coordinates?” in the 2D layers.

Each layer then shows its Y level and its X and Z range, starting one block below the beacons, and the range question shows where the effect reaches. In the Overworld the whole pyramid has to fit between Y −64 and Y 319.

Enter your coordinates

What range and duration does the calculator show?

The displayed effect radius uses Java values: 20, 30, 40 or 50 blocks for levels 1–4. The effect lasts 11, 13, 15 or 17 seconds; Java re-applies it every 80 game ticks (4 seconds at normal tick speed) while you stay in range. This is an effect estimate, not a map of every affected block or an edition-specific beam simulation.

How are these materials counted?

The table adds the area of each solid layer; the calculator also supports the shared rectangular bases described above. It counts the pyramid separately from crafting and activating the beacon, as described in the beacon section of Minecraft’s official recipe guide. That guide explains beacon basics, rather than supplying the totals in this table.

Counts assume the standard mineral-block pyramid. Mods or server rules that change beacon construction, powers, or range are outside this calculator’s scope.
