Minecraft schematic size limits

The generator will not emit an arbitrary mega-base. Free and Pro each have a hard cap on every side of the box, and the prompt’s numbers are clamped before a single block is placed. This page is that math.

The two caps

Pricing copy and checkout stay on the pricing page. Pro does not add Bedrock, and it does not raise Litematica’s own mod limits. It raises the box this compiler is willing to fill. A 48×48×48 region is the maximum volume the Pro clamp allows, not a promise that every kernel looks good as a cube. Castles want a wide footprint. Towers want height. Type the three numbers instead of assuming a cube.

How a prompt becomes a size

Three numbers in the line, each one or two digits, from 3 to 64, become width, height, and depth. “13x9x11” is exact. Two numbers set width and depth, and height is about three quarters of the smaller one. One number sets width and depth, and height is about 70 percent of it. “100” does not mean one hundred. The scanner reads two digits, so 100 becomes 10, and the leftover zero is discarded. Type 20 or 48 if you want the cap.

With no numbers, size words apply: tiny 8, small 11, medium 16, large 22, huge 32, mega 40. Then the plan clamps. Free large, huge, and mega are all 20. Pro keeps large at 22, huge at 32, and mega at 40, and a typed 48 stays 48. Width and depth will not go under 5. Height will not go under 3. A castle is raised to at least 15 on width and depth when the cap allows, because four turrets plus a keep do not fit in a hut footprint. On free, a castle you described as 8×8×8 still grows toward 15 and then stops at 20, so you simply get a small castle, not an error.

The word list and the shape priority are on prompt tips. A size cannot turn a house prompt into a castle. Shape is chosen first.

What still fits for free

The house preset is 13×9×11. The spruce cabin preset is 11×8×11. A 9×18×9 tower fits in 20. A 16×12×16 castle fits. The default farm is 15×7×13. The default bridge is 19×8×7. All of those are legal on the free plan, and they are the sizes the kernels were tuned around. You do not need Pro to download a starter house .litematic.

You do need Pro if you want a typed side longer than 20, including a 21×14×21 castle (the text preset on the castle page uses 21, which free will clamp down) or a wall you described as 32 long. If the preview looks stubbier than the numbers you typed, the clamp did it. Read the size in the result before you build the material list into a shopping trip.

Daily quota is not the same as size

One free generate per UTC day means one compile, which already includes both downloads. You do not spend the generate twice to get the .schem. Details are on schem to litematic. Leaving the tab and coming back tomorrow is a new generate. Failed loads in Litematica are not a size problem. A 20-block house fails the same way as a 48-block house if it is in the wrong folder. Use Litematica not working for that, and import for the path.

WorldEdit will paste whatever box you generated, up to that cap. It will not expand a free file to 48 after the fact. Generate on Pro if you need the larger grid, then import the .schem.
