Dimensions of a player standing. Dimensions of a player crouching.

Here is a reference page for any Counter-Strike: Global Offensive Counter-Strike: Global Offensive mapper looking for dimensions or numbers that are used for level and map creation. For other tutorials go to the Counter-Strike: Global Offensive Level Creation page.

Crouching 54 46.076218
Warning.png Warning:  In Hammer, the bounding box of all player spawn entities (except info_player_start and info_player_logo) do not use the player width/length of 32 units, instead using 26 units. Don't use these entities as a reference for the player width/length.
Note.png Note:  A corridor must be wider (!) than 32 units to be accessible to players.
Idea: To test in Hammer if a player fits in a narrow/angled corridor, you can make a temporary 32 x 32 x 72 (or 32 x 32 x 54) block representing the dimensions of a player and move it to various locations inside the corridor. It is traversable if the volume of the block and surrounding geometry (including vertices and edges) do not intersect. Hold Alt while dragging to prevent the block from snapping to the grid.

Warning.png Warning: 
  • Sometimes, there are differences between 64 tick and 128 tick. If there are two numbers in a cell of this table, the first is the one for 64 tick and the one in brackets is the one for 128 tick. Interestingly, it is sometimes possible to reach the 128 tick block height with 64 tick (e.g. getting on a 66 units block) but requires something like strafing on the edge of the block.
  • There are two slightly different ways of Crouch Jumping, which is why we use different terms here:
    • By Jump then Crouch we mean first invoking +jump and then +duck.
    • By Crouch then Jump we mean first invoking +duck and then +jump during the crouching transition.
  • The numbers in this table concerning jumps assume full stamina. That means that the player has recovered from previous landings, hitting the ground.
Note.png Note: 
  • The Lowest Wall Height cannot peek over can be considered the Eye Level rounded up.
  • Players standing on a player that does not touch the ground or that stands on another player will slide forward (and unduck) and the invocation of +left, +right, +back, +duck and +speed has no effect.
  • These numbers have been obtained using a special map, cl_showpos 1, as well as getpos and host_timescale.



Fall Damage

For the follownig table, we assume that a player is standing on something with a given height from the ground that he falls down from. The fall damage that the player will receive does not only depend on the technique the player uses to fall down but also on the tickrate.

Warning.png Warning: 
  • Standing players running/jumping off a block and crouching before landing might receive slightly more damage.
  • Players crouching off a block and uncrouching in mid-air might receive slightly less damage.
  • Players uncrouching perfectly just before landing make no noise and don't receive any fall damage, regardless of the fallen distance.
  • There is a default fall damage reduction of 60 % when wearing an exojump controlled by the ConVar sv_falldamage_exojump_multiplier.
Note.png Note: 
  • Players jumping on a block with a height of 9 (128 tick: 11) units or higher will land on it silently (no crouching).
  • Players running off a block with a height of 20 units or more will fall. Otherwise they "stick" to the ground.
  • Players running off a block with a height of 47 (128 tick: 46) units or less will land silently.
  • Players running off a block with a height of 214 to 222 units hear a fall damage sound but don't receive any damage (64 tick only).
  • Players jumping off a block with a height of 159 to 162 units hear a fall damage sound but don't receive any damage (128 tick only).
  • The fall damage doesn't exceed 695 because sv_maxvelocity is 3500 by default. If higher, the maximum fall damage also increases.
  • All fall damage is multiplied with sv_falldamage_scale.

Note.png Note: 
  • A player can still survive bigger height differences by uncrouching just before landing. Use e.g. trigger_hurt appropriately if you wish to prevent a player's survival.
  • The smallest initial height that a player needs to hurt himself is 151 units: crouch then jumping off and staying crouched deals 1 damage. With an exojump, it needs just an initial height of 79 (128 tick: 75) units.



Grenades

  • The smoke grenade diameter is roughly 256 units with a height of about 128 units.
    • When smoking a corridor precisely, it is always possible to entirely cover a width of 200 units with no gaps, assuming no height differences in the floor.
    • Corridors with a width of about 256 units or more cannot be covered without gaps.
    • The smoke "shines" through (thin) walls.
  • Molotovs and incendiary grenades have a similar diameter as a smoke grenade.
    • They can easily cover a width of 256 units or less, but not too much more than that.
    • The flames tend to be blocked by (vertical) walls, making them spread in other directions.
