# Loaded Chunks

### <span data-darkreader-inline-color="" style="color: rgb(230, 126, 35);">Loaded Chunks/Simulated Chunks</span>

<span data-darkreader-inline-color="" style="color: rgb(149, 165, 166);">Loaded Chunks also known as simulated chunks are the chunks that anything can normally process in. These chunks only occur around a player or created with the use of **/tickingarea** or **Add-ons.** These chunks are what players will spend their time interacting with a majority of the time.</span>

<p class="callout info"><span data-darkreader-inline-color="" style="color: rgb(149, 165, 166);">These chunks are represented by the hex code 0x0009 in the game code.</span></p>

### <span data-darkreader-inline-color="" style="color: rgb(230, 126, 35);">Buffer Chunks</span>

Around every loaded chunk is a buffer of <span data-darkreader-inline-color="" style="color: rgb(230, 126, 35);">[unloaded chunks](https://bedrockwiki.com/books/chunks/chapter/unloaded-chunks)</span> this is to improve load times and general stability of the game.

<span data-darkreader-inline-color="" style="color: rgb(126, 140, 141);"><span data-darkreader-inline-color="" style="color: rgb(149, 165, 166);">The size of the area of loaded chunks around a player is dependent on the **simulation distance** setting in the world settings and it comes in four different sizes 4 chunks, 6 chunks, 8 chunks, and 12 chunks. These sizes are not radii as you may be inclined to believe but instead follow <span style="color: rgb(230, 126, 35);">[taxicab geometry](https://en.wikipedia.org/wiki/Taxicab_geometry)</span>, going from each corner of the central chunk containing the player.</span></span>
