Minecraft Redstone Tick Calculator
Work out exactly how long a redstone circuit will take — convert ticks to seconds, plan repeater chains for a specific delay, or design a clock that pulses at the period you want. Handy when you're building auto-farms, hidden doors, or timed traps.
Three quick redstone timings
1. Ticks ↔ Seconds
1 redstone tick = 0.1 seconds. Type either box, the other updates.
2. Repeater chain for a target delay
Each repeater delays 1, 2, 3 or 4 ticks. This tool finds the shortest chain that hits the delay you want.
3. Redstone dust signal range
Signals start at strength 15 and lose 1 per block. Repeaters reset them to 15.
Redstone timing in plain English
Redstone in Minecraft runs on discrete steps called ticks. Every tenth of a second, the whole game checks every redstone circuit and updates it. That's why redstone circuits feel a little "steppy" compared to real electronics — you can't have a delay of, say, 0.15 seconds, because the game only checks in tenth-of-a-second chunks.
A repeater is your main tool for controlling those steps. Right-click a placed repeater and its delay bumps up by one tick (up to 4, then wraps back to 1). Chain them together and you can build any delay you want — the calculator above works out the shortest chain so you don't end up placing 40 repeaters when 10 would do.
Two extra things worth knowing:
- Signals through redstone dust weaken by 1 each block, so a plain dust line dies at block 15. Use repeaters as booster stations to go further.
- Observers and comparators have their own timing rules — see the FAQ below for the short version. If you need a specific delay, always use repeaters.

Every redstone component, in plain English
Short guide to what each piece does and where you get it. Skip to the ones you care about.
Redstone Dust
What it does: the "wire" of redstone. Placed on the ground, it carries a signal from block to block. Signal starts at strength 15 and drops by 1 for every block travelled — so it dies at block 15 unless you boost it with a repeater.
Where you get it: mine redstone ore blocks (deep in caves, Y −59 or lower is the sweet spot). Each block drops 4-5 dust with a normal iron pickaxe, more with Fortune. Villager clerics also trade dust for emeralds.
Redstone Torch
What it does: a permanent signal source. Powers any adjacent block or dust with strength 15. It's also a NOT gate — when the block below is powered, the torch turns OFF. That's how nearly every redstone contraption inverts a signal.
Where you get it: craft one stick + one redstone dust in a crafting table. Cheap, plentiful, and doesn't need updating.
Redstone Repeater
What it does: three jobs in one. (1) resets a dying signal back to strength 15 — think booster station. (2) forces the signal to travel one direction only. (3) adds a delay of 1, 2, 3 or 4 redstone ticks (0.1s per tick). Right-click to bump the delay up.
Where you get it: craft 3 stone + 2 redstone torches + 1 redstone dust. Or trade with a novice-level villager. This is the tool the calculator above chains together for you.
Redstone Comparator
What it does: reads block state and does maths on signals. Two modes: compare (front torch off) passes the strongest input; subtract (front torch on) subtracts side input from back input. Also detects how full a chest, furnace or hopper is — huge for auto-sorters and item farms.
Where you get it: craft 3 stone + 3 redstone torches + 1 nether quartz. The quartz means you need a trip to the Nether first.
Piston (Regular & Sticky)
What it does: pushes up to 12 blocks in a line when powered. A sticky piston also pulls the block back when it retracts — that's the one you want for hidden doors and folding builds. Pistons cannot push obsidian, bedrock or tile entities (chests, furnaces, etc.).
Where you get it: regular piston = 3 planks + 4 cobblestone + 1 iron + 1 redstone. Sticky piston = regular piston + 1 slimeball (or a honey block in a pinch).
Observer
What it does: watches the block directly in front of it. Any block state change (crop growth, water flow, doors opening, a piston moving) makes it fire a 1-tick pulse out the back. Perfect for auto-farms: place one in front of a fully-grown crop and it triggers the harvest the moment the crop ripens.
Where you get it: craft 6 cobblestone + 2 redstone + 1 nether quartz in a crafting table.
Hopper
What it does: transfers items into the container below it. Sucks up items from any container above (or floating items on top). Only moves 1 item every 4 game ticks (0.2s) — that's the maximum throughput to remember for bigger farms. Pipe several in a line for item sorters.
Where you get it: craft 5 iron ingots + 1 chest. Not cheap early game — save your iron for the ones you actually need.
Dispenser & Dropper
What they do: both eject items from a 9-slot inventory when powered. A dispenser uses the item (fires an arrow, sprays water, places a boat), a dropper just throws it as an item. That's the only difference. Both fire one item per redstone pulse.
Where you get them: dispenser = 7 cobblestone + 1 bow + 1 redstone. Dropper = 7 cobblestone + 1 redstone (no bow). Droppers are cheaper — use them when you don't need item-launch behaviour.
Redstone timing FAQ
A redstone tick is the smallest unit of time in a redstone circuit — one redstone tick is exactly 0.1 seconds. That's why redstone feels a little "chunky" compared to real electronics: everything jumps in tenth-of-a-second steps. Note the difference between a "redstone tick" (0.1s) and a "game tick" (0.05s) — two game ticks per redstone tick. The calculator above uses redstone ticks because that's what repeaters count in.
On its shortest setting (right-click 0 times after placing), a repeater delays the signal by 1 redstone tick, or 0.1 seconds. Right-click to bump it up: 2 ticks (0.2s), 3 ticks (0.3s), or the maximum 4 ticks (0.4s). If you need a longer delay, chain repeaters — the calculator above works out the cheapest chain for the delay you want.
A redstone signal starts at strength 15 and loses 1 strength for every block of redstone dust it crosses. That means signals die after 15 blocks. To go further, place a repeater — it resets the signal back to 15 and gives you another 15 blocks of range. Repeaters cost a small delay each, though, which the calculator factors into the timing.
The fastest reliable redstone clock is a 1-tick clock (0.1s period), usually built with an observer or a piston that keeps flipping itself. Very fast clocks can lag your server and are usually overkill — for most farms, a 2-4 second clock (built from 3-4 repeaters on max setting looped back) is plenty. Enter your target period above to see how many repeaters you'd need.
Yes, but with their own quirks. An observer sends a 1-tick pulse (0.1s) every time the block it's watching changes — great for auto-farms. A comparator has no delay of its own by default, but adds 1 tick of delay when it's in subtract mode. Neither is adjustable like a repeater — if you need a specific delay, use repeaters and let the calculator tell you the shortest chain.
