Overview
inZOI's Creative Studio includes one of the most detailed body customization systems in the life simulation genre. Players can adjust nearly every aspect of their Zoi's physique using a combination of drag sculpting, dedicated sliders, and body presets. The system supports a wide range of body shapes, from slim to heavy, with fine control over individual body parts. With over 250 customization options across the entire character creation process, body type editing is a core part of building a unique Zoi.
Customization Methods
Body type customization uses two primary methods that work together: free-form drag sculpting and slider-based controls.
Drag Sculpting
The most intuitive method is dragging directly on your Zoi's body model. Clicking on any body region highlights it, and dragging in different directions adjusts the shape, size, and proportions of that area. This works similarly to clay sculpting and gives precise control over how each body part looks from different angles.
When you click on a body part, dot-style sliders appear that let you fine-tune the adjustment. Each dot can be dragged to reshape the selected area. This system lets players make subtle changes that would be difficult to achieve with traditional numbered sliders alone.
Primary Sliders
Two global sliders control the overall body shape before fine-tuning individual parts:
Slider | Effect | Impact on Other Sliders |
|---|---|---|
Body Weight | Adjusts overall body mass from thin to heavy | Changes all individual body part sliders proportionally |
Muscle Mass | Controls muscle definition from soft to toned | Independent; does not affect other sliders |
The body weight slider is a global modifier. Moving it affects the size of every body part at once, including the face. This is useful for establishing a general build before making targeted adjustments. The muscle mass slider operates independently and only changes how defined the muscles appear without altering the body's proportions.
Edit Modes
The body editor offers two modes for adjusting individual parts:
Mode | Behavior |
|---|---|
Symmetry Mode | Adjustments to one side of the body mirror to the other side automatically (e.g., both arms adjust together) |
Individual Edit Mode | Each body section can be edited independently without affecting any other part |
Symmetry mode is the default and is recommended for most body types. Individual edit mode is useful for creating asymmetric characters or making very precise adjustments to one side.
Adjustable Body Parts
Players can click on and adjust the following body regions using the dot slider system:
Body Part | Adjustments Available |
|---|---|
Neck | Thickness, length |
Shoulders | Width, slope, height |
Arms | Upper arm thickness, shape |
Forearms | Forearm thickness, shape |
Chest / Bust | Size, shape, spacing, height |
Waist | Width, definition |
Hips | Width, shape |
Buttocks | Size, shape, projection |
Thighs | Thickness, shape |
Legs (Lower) | Calf thickness, shape |
Hands and feet cannot be customized in the current version of the game. Facial features are edited through a separate system with its own set of detailed controls for eyes, nose, mouth, jawline, and skin texture.
Body Presets
For players who prefer not to manually sculpt every detail, the Creative Studio offers a selection of body presets covering a range of body types. Selecting a preset applies a predefined body shape that can then be further modified with sliders and drag editing. Body presets are separate from face and outfit presets, so choosing a body preset does not change your Zoi's facial features or clothing.
Body Hair
Male-presenting Zois have access to body hair sliders that are not available for female-presenting characters. These sliders control hair density and distribution across three regions:
Chest: Adjusts chest hair from none to full coverage
Arms: Controls arm hair visibility
Legs: Controls leg hair visibility
Height
Height cannot be adjusted in inZOI. All Zois of the same gender presentation and age group are the same height. The developers have confirmed this is a deliberate limitation because the game uses pre-programmed animations. Allowing different heights would break interaction animations such as hugging, handshakes, and conversations where two Zois need to face each other at matching positions.
February 2026 Realism Update
On February 13, 2026, Director Hyungjun Kim addressed community feedback about body representation. Players had noted that wider and heavier body types looked artificially smooth, with curves that did not reflect real body variation. The update changed how larger body types are rendered:
Reduced artificial smoothing on wider and bigger Zois
Added more natural skin textures and subtle body contours
Improved proportions for all body sizes to look more realistic
Preserved the existing range of body shapes while making them appear more natural
Before this update, the game had a tendency to make body shapes look flawless with perfectly smooth curves. The change introduced more organic variation, particularly visible on larger body types where skin folds, natural contours, and realistic proportions replaced the previous airbrushed appearance.
Impact on Gameplay
Body type in inZOI is entirely cosmetic. A Zoi's physical build does not affect their skills, career performance, relationships, or interactions with other Zois. All body types have identical gameplay capabilities. This is a deliberate design decision to let players create Zois that look however they want without worrying about stat penalties or advantages tied to appearance.
Clothing items adapt to different body types automatically. Outfits stretch and adjust to fit the character's proportions, so players do not need to worry about finding size-specific clothing.
