Standing up as a wall, one block thick.
Blocks
One family reads as a deliberate build up close. Every block gets the closest colour from a distance and looks like noise next to it.
Floyd-Steinberg: the colour a block could not hit is pushed into its neighbours, which buys shades the palette does not have.
Materials
Take it into the game
A Java structure block places up to 48 blocks on a side, so anything wider than that wants the schematic or the function file.
Bedrock has no such cap. Open the .mcpack to import it, turn it on under the world's Behavior Packs (cheats have to be on), stand where its north-west corner should go and run /structure load mcmaps:pixel_art ~ ~ ~. Wide pieces place as their chunks load, so stay close. On Windows a structure block can also import the .mcstructure file.
Picking a width
Width is the only decision that really matters. It sets the block count, the build time and how much detail survives, and every one of those grows with the square of it: doubling 32 to 64 turns a 1,000 block afternoon into a 4,000 block weekend.
A face or a logo reads at about 32 blocks. Anything with small text in it needs 64 or more, because a letter has to be several blocks tall before it is a letter rather than a smudge. Past 128 you are building something that only reads properly from a long way off, and the schematic is the sane way to place it.
Standing or flat
A standing wall is the usual answer and the one the plan is drawn for: rows from the bottom, one block thick. Flat lays the same picture on the ground, which is what you want for something read from the air, a floor pattern, or a build you will later cover with a glass roof. The block count is identical either way; only the plan and the commands change.
Frequently Asked Questions
How do you make pixel art in Minecraft?
Pick an image, decide how wide it should be in blocks, and build it a row at a time from the bottom. Every pixel becomes one block, so a 64 wide picture is a 64 block wall. This tool does the colour matching and gives you the plan, with the row you are on picked out so you do not lose your place.
How is this different from map art?
Map art matches the 61 colours a filled map can display and hangs flat in item frames. Pixel art matches the real colour of the block itself and stands up as a wall you walk past. Different palettes, different maths, different builds. Use the map art studio for the first one.
Should I turn dithering on?
For photographs and anything with a gradient, yes. Dithering pushes the colour a block could not hit into its neighbours, which buys shades the palette does not physically have, at the cost of speckle up close. For logos, flags and flat cartoon art, turn it off: those are already made of solid colours and dithering only adds noise.
How many blocks will it take?
Width times height. A 64 wide image of a square picture is 4,096 blocks, which is 64 stacks. The material list on this page splits that by block so you know how much of each colour to gather, and the total is shown in stacks as well.
Which blocks does it use?
Only ones that hold a wall up. Anything that falls, like sand, gravel and concrete powder, is excluded, along with anything that is not a full cube. With every block allowed it also skips blocks with different faces and blocks that change after placing, like infested stone, unwaxed copper and living coral. You can also restrict the whole build to one family, such as concrete or wool, which looks far more deliberate up close.
Can I paste it in on Bedrock?
Yes. The Bedrock pack (.mcpack) is a behavior pack with the finished wall inside as a structure. Import it, turn it on under the world's Behavior Packs and run the /structure load command shown under the exports, and it places from wherever you stand. Bedrock has no 48 block cap like the Java structure block, but a very wide wall only finishes once you are close enough for its far end to load. On Windows a structure block can also import the bare .mcstructure file.
