The Basic Answer: 1/20th of a Second
In Minecraft, one tick lasts exactly 0.05 seconds, or 1/20th of a second. This means the game processes 20 ticks every single second under normal conditions. Think of ticks as the game’s heartbeat – they’re the tiny time intervals when Minecraft updates everything happening in your world.
What Happens During Each Tick
Every tick, Minecraft performs countless calculations. Mobs move, redstone circuits activate, crops grow, water flows, and blocks update. It’s like the game taking a snapshot, making all necessary changes, then moving to the next frame. This consistent timing is why redstone contraptions work reliably and why you can predict when things will happen.
Server vs Client Ticks
There’s an important distinction between server ticks and client ticks. Server ticks handle the actual game logic – mob AI, block updates, and world changes. Client ticks manage what you see on screen – animations, particle effects, and visual updates. Both aim for 20 ticks per second, but they can run at different speeds depending on performance.
When Ticks Slow Down
Sometimes your game can’t maintain the full 20 ticks per second. This happens when:
- Too many entities are loaded (hundreds of mobs or items)
- Complex redstone machines are running
- Your computer or server is struggling with performance
- Large world generation is happening nearby
When this occurs, everything in the game slows down proportionally. A furnace that normally smelts an item in 10 seconds might take 15 seconds if the server is running at only 13 ticks per second instead of 20.
Practical Applications
Understanding tick timing helps with redstone engineering and farm design. For example, a hopper transfers one item every 8 ticks (0.4 seconds). Knowing this lets you calculate exactly how fast your item sorting systems will work. Similarly, most crops have a random chance to grow each tick, so more frequent ticks mean faster crop growth.
Whether you’re building complex contraptions or just curious about game mechanics, understanding Minecraft’s tick system opens up a whole new level of gameplay possibilities.
TL;DR
One Minecraft tick lasts exactly 0.05 seconds (1/20th of a second), with the game running 20 ticks per second under normal conditions.
