Turret range is a circle, and lanes are straight corridors. That mismatch is worth a free auto-attack every wave, and almost nobody uses it.
League of Legends Guide
Turret Aggro Range
Updated August 2026
A turret's range is a circle drawn around the turret. A lane is a straight corridor running past it. Those two shapes do not agree with each other, and the disagreement is free value if you know where to stand.
The short version: approach diagonally rather than straight down the lane, and you can stand meaningfully further up the corridor for the same distance from the turret. That is usually the difference between being able to auto-attack someone last-hitting under their turret and not.
The Numbers Worth Knowing
Three distances govern everything below, and they are all different from each other, which is the main reason this feels confusing in game.
750 — attack range
How far the turret can actually shoot. Measured edge to edge, so your champion's body counts. Outside this, nothing it wants to do to you matters.
1350 — sight radius
How far the turret can see. Nearly double its reach, which is why it watches you walk up long before it can do anything about it.
1400 — the aggro trigger
Damage an enemy champion standing within this range of their turret and the turret turns on you. Almost twice its attack range.
It holds its target
Once a turret picks something, it keeps hitting it until that target dies, leaves its range, or stops being targetable. It does not re-choose every shot.
The correction to the original version of this guide. This post used to say that positioning correctly meant you could harass "without ever pulling turret aggro". That is not quite what happens. The trigger for a turret turning on you is damaging someone within 1400 of it, and that is nearly twice the 750 it can actually shoot from.
In practice you are still safe, because a turret cannot hit what it cannot reach. What it changes is the margin. There is no grace period and no wind-up: step inside 750 after landing your harass and you are already the thing it is aiming at. Plan the step back before you throw the punch, not after.
Why Diagonal Beats Straight
In the lead image the champion is directly in line with the turret, and it has locked on — the outline lights up and it makes a noise at you. In this one the champion has stepped off to the side of the lane, is standing further up the corridor, and the turret is doing nothing.
Nothing has been exploited. It is just that distance from the turret is measured as the crow flies while progress up the lane is measured along the lane. Trading some of one for the other is allowed.
The size of the trade is modest and worth being honest about. Step roughly four hundred units to the side and you buy back a bit over a hundred along the lane. A hundred units is not dramatic, but it is a real slice of an auto-attack range, and it is repeatedly the difference between reaching someone last-hitting and watching them do it.
Where the Enemy Is Forced to Stand
This is the half that makes the positioning worth anything, and it is the half people skip. Standing diagonally is only useful if it puts you near where your opponent has to be.
They do not get a free choice. The minion wave arrives in a shape, and if they want to last hit all of it rather than give up gold, they have to stand roughly where the wave is — the circled area. The X is where they would prefer to be, safely tucked behind the turret and away from you, and taking it means giving up minions.
So pick your side to match. Approach diagonally from the side the wave is on, and their farming spot and your safe spot end up next to each other. Do it from the wrong side and you have gained nothing at all: they simply drift to the far edge of the wave and you are stuck choosing between missing and diving.
Step in, attack, step out. This is a poking pattern, not a standing position. Move in, release the auto-attack, and start walking back the instant it fires rather than when it lands — the damage happens on release. The same footwork is covered in more detail in our guides on auto-attack spacing and early game harassing.
Bot Lane, Where It Pays Best
Bot lane is where this earns the most, because it is where the long-range carries live. A marksman with real reach gets the whole benefit of the extra hundred units, and the enemy has two people down there who both want to farm.
The obvious caution still applies, and it has aged well. Hugging a side wall to squeeze out range puts you next to terrain, and terrain is where you get caught. Against anything that can pin you against it — Alistar, Vayne, hook supports generally — the extra reach is not worth the position you have to take to get it. Do this into lanes that cannot punish you for it, not into lanes that are waiting for exactly this.
What Has Changed Since 2013
The screenshots are from the pre-2014 Summoner's Rift, so the terrain art and the turret models look nothing like they do now. Read them for the geometry.
Turrets themselves have gained a lot of machinery in the meantime. Outer turrets now carry five plates of a thousand health each, which fall away fourteen minutes in, and they pick up stacking resistances as they are damaged. None of that touches the mechanic on this page. Range, sight and the aggro trigger are what the positioning depends on, and those still behave the way the screenshots show.
If a term here is unfamiliar, the League of Legends Terms Glossary has the current names.

Frequently Asked Questions
What is a turret's range in League of Legends?
750, measured edge to edge, so your champion's body counts toward it. Its sight radius is much larger at 1350, which is why a turret watches you approach long before it can shoot you.
What makes a turret target you?
Damaging an enemy champion who is within 1400 range of their turret. That trigger radius is nearly double the turret's own 750 attack range, so you can take aggro from a distance it cannot shoot from. Once a turret has a target it keeps hitting it until that target dies, leaves its range, or becomes untargetable.
Why does standing diagonally let you get closer?
Because turret range is measured as a straight-line distance while progress up the lane is measured along the lane. Offsetting to the side lets you stand further up the corridor at the same distance from the turret. Around four hundred units to the side buys back a bit over a hundred along the lane.
Is it safe to harass someone under their turret?
Yes, as long as you stay outside 750 and step out on the attack's release rather than waiting for it to land. The risk is not the turret, it is the enemy: hugging a side wall to gain range puts you next to terrain, which is exactly where engage supports and champions with displacements want you.
Does turret plating change any of this?
No. Plates are a health and gold system on outer turrets — five of them, a thousand health each, gone fourteen minutes into the game. They do not affect range, sight, or what makes a turret pick a target.

Nice article. This will help me improve my ADC skills a lot more.
ReplyDeleteWow man! GJ with this article!
ReplyDeleteHuh I just noticed that all the towers line up against the wall, occupying the edge if the lane. This means the other edge will have less coverage and thus allows you to be deeper in.
ReplyDeleteThis is awesome. I always wondered why I get continually harassed under tower, while every time I try, I would get tower shots to the face. Gotta try this out!
ReplyDeleteI think the phrasing is wrong but the concept is 100% right. Now I may have miss read wrong. by standing diagonal you are not standing any farther away from the turret. you are still standing at a straight line from the turret just in a different direction. Turrets agro is based a circle radius if I am not mistaken and all a radius is the same exact distance from a single point to form a circle. the reason why you can harass more easily is because you force the enemy champ to fit in that circle that you were talking about to actually get every cs. with them standing it brings them close to you which allows you not to go into that turret radius so you can easily get out quick enough after an auto like you said. but lets say the enemy is very noob and dumb. and they stand in front of the turret. then you would not want to stand diagonal because it would put you farther away you would want to stand in front because then you are closer to enemy and would not have to get in turret agro. I hope this makes since
ReplyDeleteanother side note. say the opponent was in between the tower and terrain wall in mid tower. the most optimal place to be to harass technically would be in the little path way leading to blue buff on either side that puts you close to enemy but with out taking turret shot but I strongly do not recommend this because then you are very easily set up to be ganked and killed.
