How to Change Your Character’s Size in Roblox Games

Key Takeaways

  • Roblox allows you to adjust the scale of your character’s body parts for a unique look
  • For R15 avatars, you can change the scale using special properties in the Humanoid object
  • For R6 avatars, you need to manually resize each body part and potentially re-rig the character

Customizing your character’s appearance is a big part of the Roblox experience. While the platform offers a wide range of avatar customization options, sometimes you may want to go beyond the default settings and change the actual size of your character. Whether you want to make your avatar taller, shorter, wider, or slimmer, Roblox provides ways to achieve this in games.

The process of changing your character’s size differs depending on whether you’re using an R15 or R6 avatar. R15 avatars, introduced in 2014, are the newer and more advanced character rigs that offer improved animations and customization options. R6 avatars, on the other hand, are the older character models that have been around since the early days of Roblox.

Changing the Size of R15 Avatars

For R15 avatars, Roblox has built-in properties within the Humanoid object that allow you to scale different parts of your character’s body. These properties are:

  • HeadScale: Adjusts the size of your character’s head
  • BodyHeightScale: Changes your character’s overall height
  • BodyDepthScale: Modifies the depth or thickness of your character’s body
  • BodyWidthScale: Alters the width of your character’s body

To change the size of your R15 avatar, you can use a server-side script that modifies these properties when a player joins the game. Here’s an example script:

game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(character)
        local humanoid = character:WaitForChild("Humanoid")
        if humanoid.RigType == Enum.HumanoidRigType.R15 then
            local scale = 0.5 -- Adjust this value to change the scale (0.5 = 50% of default size)
            humanoid.HeadScale = scale
            humanoid.BodyHeightScale = scale
            humanoid.BodyDepthScale = scale
            humanoid.BodyWidthScale = scale
        end
    end)
end)

This script waits for a player to join the game, checks if their avatar is an R15 rig, and then applies a custom scale to the character’s body parts. You can adjust the scale variable to increase or decrease the size as desired.

Changing the Size of R6 Avatars

Modifying the size of R6 avatars is a bit more involved since there are no built-in properties for scaling. Instead, you need to manually resize each body part and potentially re-rig the character to ensure proper animations and physics.

Here’s a general approach you can take:

  1. Get references to the character’s body parts: First, you’ll need to get references to the character’s head, torso, and limbs. You can do this by accessing the Character object of the player.
  2. Resize the body parts: Once you have references to the body parts, you can change their Size property to make them larger or smaller. Keep in mind that you’ll need to adjust the size of each part individually.
  3. Reposition the body parts (optional): After resizing the body parts, you may need to reposition them to ensure they’re properly aligned with the character’s torso. You can do this by modifying the Position property of each part.
  4. Re-rig the character (optional): Depending on the extent of the size changes, you may need to re-rig the character to ensure proper animations and physics. This typically involves creating new joints or motors to connect the resized body parts.

Here’s an example script that resizes an R6 character’s body parts:

game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:Connect(function(character)
        local humanoid = character:WaitForChild("Humanoid")
        if humanoid.RigType == Enum.HumanoidRigType.R6 then
            local scale = 2 -- Adjust this value to change the scale (2 = twice the default size)
            local head = character:WaitForChild("Head")
            local torso = character:WaitForChild("Torso")
            local leftArm = torso:WaitForChild("Left Arm")
            local rightArm = torso:WaitForChild("Right Arm")
            local leftLeg = torso:WaitForChild("Left Leg")
            local rightLeg = torso:WaitForChild("Right Leg")

            head.Size = head.Size * scale
            torso.Size = torso.Size * scale
            leftArm.Size = leftArm.Size * scale
            rightArm.Size = rightArm.Size * scale
            leftLeg.Size = leftLeg.Size * scale
            rightLeg.Size = rightLeg.Size * scale
        end
    end)
end)

This script gets references to the character’s body parts, checks if the avatar is an R6 rig, and then scales the size of each part by a factor of 2 (you can adjust the scale variable as needed).

Keep in mind that resizing R6 avatars can sometimes lead to issues with animations and physics, especially if the size changes are significant. In such cases, you may need to adjust other properties or create custom animations to ensure proper character behavior.

Considerations and Best Practices

When changing the size of your character in Roblox games, there are a few important considerations and best practices to keep in mind:

  • Performance impact: Larger characters generally have more complex physics calculations, which can impact game performance, especially in multiplayer environments with many players. It’s essential to strike a balance between character size and performance optimization.
  • Collision detection: Resizing characters can affect collision detection, potentially causing issues with navigating through tight spaces or interacting with certain objects in the game world. You may need to adjust collision models or implement workarounds to ensure proper collision handling.
  • Animation compatibility: Significant size changes, especially for R6 avatars, may cause animations to break or appear unnatural. In such cases, you may need to create custom animations or adjust existing ones to ensure smooth character movement and actions.
  • User experience: While changing character size can be a fun and creative way to customize your avatar, it’s important to consider the overall user experience. Extremely large or small characters may impact gameplay or make it difficult for other players to interact with your character.

By following these tips and best practices, you can successfully change the size of your character in Roblox games, adding a unique and personalized touch to your avatar while ensuring a smooth and enjoyable gaming experience.
