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

Here is a reference page for any 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.

Measurements

Brush	Height	Depth	Width	Comment
Thick Wall		≥ 32		Unlikely to be penetrated (except glass, wood, ...).
Thin Wall		≤ 16		Penetrable for strong weapons.
Very Thin Wall		≤ 8		Penetrable for most/all weapons.
Big Crate	≥ 72	64	64	Can only see over it by jumping.
Headglitch Crate	56-60	64	64	Can choose between peeking over it or hiding.
Small Crate	≤ 44	48	48	Can always see players behind it.
Stair Step	≤ 18	≥ 16		Stairs should usually be clipped with a Slope.
Slope	≤ Depth			Walkable if at most 45.573° steep.

Note:

• These figures are just suggestions and nothing official.
• Height differences between players are not taken into account: A player crouching behind a crate that is 56 units high isn't safely covered if the enemy can see them from above.
• See also the Eye Levels of a player below.
• Test bullet penetration yourself using the cheat sv_showimpacts_penetration 1. See also: List of CS:GO Surface Types.
• Steep slopes can become walkable by setting the cheat sv_standable_normal to something under 0.7.

Player Dimensions

Player Posture	Height	Width/Depth	Feet Level	Eye Level
Standing	72	32	0.031250	64.093811
Crouching	54			46.076218

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: 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.

	Bump mine and jump	> 1300	< 1400	< 1400
	Bump mine and exo-jump	> 1600	< 1700	< 1700

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:

• 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.

	Jump off Fall Damage		Run off Fall Damage		Crouch off and stand up Fall Damage		Run off (exojump) Fall Damage

For the following tables, we assume that a player is standing on something (e.g. on a world brush) with a given height from the ground that they fall 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.

Important: A player can bypass fall damage (and the landing sound) by uncrouching just before landing. Use e.g. trigger_hurt appropriately if you wish to prevent a player's survival.

Smallest Fall Height in Units causing...	Jump off		Run off		Crouch off and stand up		Run off (exojump)
	64 tick	128 tick	64 tick	128 tick	64 tick	128 tick	64 tick	128 tick
≥ 1 damage	167	163	223	216	232	225	223	220
≥ 25 damage	247	243	303	301	312	310	447	451
≥ 50 damage	340	342	396	393	405	402	767	772
≥ 75 damage	459	454	516	505	525	514	1173	1179
≥ 100 damage	578	573	635	631	644	640	1666	1672
≥ 120 damage	693	687	750	737	759	746	2127	2120

Note:

• The fall damage is slightly higher when landing crouched as opposed to landing uncrouched.
• 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.
• When wearing an exojump, there is a default fall damage reduction of 60 %, controlled by the ConVar sv_falldamage_exojump_multiplier.
• 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 smallest initial height that a player needs to hurt themselves 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.

An approximation for the fall damage of a player running off some height on 128 tick is 9.525 * sqrt(height) - 139.25. The resulting damage value must be clamped to the upper limit 695, then multiplied with sv_falldamage_scale (and also with sv_falldamage_exojump_multiplier if the player wears an exojump) and finally the value must be rounded down and clapmed to the lower limit of 0. As a C function, it could look like this:

int damage(float height, bool playerWearsExojump) { float damage = 9.525 * sqrt( height ) - 139.25; damage = MIN(695, damage) * sv_falldamage_scale; if (playerWearsExojump) damage *= sv_falldamage_exojump_multiplier; return MAX(0, (int) damage); }

The error of this approximation should be at most 1 damage point. For jumping off, add 54.8 to the input height to get a result of a similar precision. For the Crouch off and stand up damage subtract 9.6 from the input height.

Grenades

Highest throwing Distance on a plane in Units

Throwable Type	Distance (with Jumpthrow)
	Standing	Running
Smoke Grenade Decoy Grenade	≈ 1754 (2653) Pitch: -32.9 (-27.4)	≈ 3045 (4380) Pitch: -40.7 (-33.0)
Tactical Awareness Grenade Snowball	≈ 1494 (2335) Pitch: -38.1 (-30.6)	≈ 2494 (3734) Pitch: -46.8 (-39.2)
Molotov Incendiary Grenade	≈ 1247 (1385) Pitch: -18.0 (6.3)	≈ 1876 (2015) Pitch: -18.0 (7.4)
Flashbang HE Grenade	≈ 1050 (1113) Pitch: -10.4 (9.0)	≈ 1555 (1618) Pitch: -10.5 (9.1)
Breach Charge	≈ 363 (632) Pitch: -40.8 (-32.2)	≈ 614 (1017) Pitch: -49.6 (-38.7)

The table on the right indicates the maximum distance that the different types of grenades can be thrown by players, assuming no height differences in the floor and measured in 2D, rounded to whole units. It also contains the approximate angle at which a player must look up or down to achieve these throwing distances. A pitch of 0 means looking straight forward, -90 or 90 means straight up or down respectively. A jumpthrow is the act of holding one or both attack buttons down and then invoking the command sequence +jump; -attack; -attack2 at once. For a breach charge, it is +jump; +attack.

• Players cannot throw a grenade higher than 1490 units.

Smoke

• 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.

Fire

• 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.
