How To Use Minecraft '/fill' Command In Minecraft Bedrock

Hey everybody, it’s UnderMyCap, and welcome back to another post. Today I’m going to show you how to use the /fill command in Minecraft Bedrock.

This is a very simple command to learn, it’s fun to use, and it’s useful in a lot of situations. If you’ve ever wanted to build a massive cube or create a hollow area quickly, /fill is the right command for you.

I’ve also made a video on this for Minecraft Java. If you want the Java version, you can check that out as well.

How to Use the Basic /fill Command

First, open the command line (type /). In Bedrock edition, you’ll see the command interface appear. Then type:

/fill

After /fill, you need to enter two sets of coordinates:

• The first set is one corner of the area you want to fill.
• The second set is the opposite corner of the area you want to fill.

If you don’t have a set location in mind, you can use tildes (~) to fill relative to your current position. For example, you can do something like:

/fill ~ ~ ~ ~ ~ ~ <block>

Before you hit enter, you also need to specify the block you want to fill with. For example, you might choose glass, dirt, stone, or any other block.

Understanding Size (Why It Sometimes Looks Bigger Than Expected)

One important thing to keep in mind is that the fill area is inclusive, meaning it includes both the start and end coordinates. So if you fill from one position to another “three blocks away,” it may appear like a 4×4 area because both ends count as part of the filled region.

Using Exact Coordinates

You can also fill using specific coordinates instead of relative ones. One way to help find coordinates is to set your world spawn and then reference the coordinates shown on-screen. From there, type those coordinates into the /fill command.

This method can feel a bit complicated at first, but it’s one of the easiest ways to be precise when selecting the corners of your fill area.

Fill Modes: Extra Options You Can Add

After the coordinates and the block type, Bedrock also lets you add an additional option (a “mode”) that changes how the fill behaves. These options give you more control—for example, you can create hollow shapes, preserve certain blocks, or destroy blocks and drop items.

Here are the key options you can use.

destroy

The destroy option breaks the blocks in the fill area and replaces them with your selected block, while also dropping the broken blocks as items.

For example, if you fill an area that contains dirt using destroy, the dirt will break and drop as collectible items.

replace

replace is similar to destroy, except it does not drop items. It simply replaces blocks in the area without breaking them into drops.

In other words, it swaps the blocks out cleanly.

keep

keep is a very useful option. It only replaces air blocks, meaning it will fill empty space but won’t overwrite blocks that are already there.

So if you have an area with existing blocks (like coarse dirt) and you only want to fill in the empty gaps, keep is the option to use.

hollow

hollow creates a hollow version of the shape. It builds the outer shell and clears the inside, leaving an empty interior you can use for rooms or structures.

outline

outline is essentially the same as hollow in terms of the result you’ll see: it creates the outer shell of the shape. In practice, they behave very similarly, and both can be used to create a shell around an area.

Final Thoughts

That’s the basics of the /fill command in Minecraft Bedrock, including the different modes you can use to control how it fills an area.

Thanks so much for reading, and I’ll see you next time.
