Roblox R6 vs R15 vs Rthro: Avatar Body Guide
Verified November 7, 2026 · Status: live feature
Roblox has three avatar body types: Classic (R6, 6 joints, simplified), R15 (15 joints, standard modern), and Rthro (realistic proportions, multiple body shapes) — switch at Avatar page → Body → select type; clothing and accessories made for one type may not fit another, and some experiences force one type regardless of your selection.

Symptom → cause → first action
| Problem | Likely cause | First action |
|---|---|---|
| Accessory won’t equip | Item is for R6; you’re on R15 or vice versa | Avatar → switch body type |
| Avatar looks strange after bundle swap | Head + body from different rigs mismatch | Pick all pieces from same rig family |
| Experience forces specific rig | Experience setting overrides your preference | No fix; experience-wide setting |
| Can’t find animation pack | Animations tied to specific body type | R15 has most animations; R6 is limited |
| Rthro items don’t fit R15 avatar | Rthro has different proportions | Switch to Rthro bundle to wear the item |
| Items disappeared from inventory | Reset items on body type swap | Click Equip on each; type conflicts |
Body type comparison
| Type | Joints | Animations | Item compatibility |
|---|---|---|---|
| Classic (R6) | 6 | Limited (older) | R6-specific gear only |
| R15 | 15 | Full modern set — walks, idles, emotes | Most clothing / accessories |
| Rthro (Normal / Narrow / Slender / Bulky) | 15 + proportions | Rthro-specific animations | |
| Rthro Mesh (newer bundles) | 15 with mesh deformation | Supports full animation set |
Switching between types
- Avatar page → Body section.
- Select R6 / R15 / Rthro (check available bundles under each).
- Click “Redraw” to preview.
- Confirm; your inventory auto-sorts items for the selected type.
- Switching is free and reversible — swap any time.
Picking the right type for your goals
- Classic (R6): Simple, lightweight, works everywhere. Best for retro-style play.
- R15: Modern default. All new animations, full item compatibility. Most players use R15.
- Rthro Normal: Realistic adult proportions. Good for RPG / realism experiences.
- Rthro Narrow: Slimmer proportions. Lifestyle / fashion experiences.
- Rthro Slender: Taller, even slimmer. Model / stylish looks.
- Rthro Bulky: Wider, muscular. Fighting / tough-guy roles.
Experience-forced types
- Experience creators can force a specific body type on all players in that experience.
- Your personal avatar choice is overridden for that experience only.
- Return to the main menu → your chosen type is restored.
- Many popular experiences force R15 for consistency and modern animation support.
- Older or retro experiences often force R6 to match the aesthetic.
Animation compatibility
| Type | Available animations |
|---|---|
| Classic (R6) | Basic walk, run, jump, sit — no advanced animations |
| R15 | Full animation set — walks, dances, emotes, custom animations |
| Rthro | R15 animations + Rthro-specific motion that fits proportions |
Buying for your type
- Avatar Shop items have an “R6 only” or “R15/Rthro” badge.
- Filter Shop → Compatible with [your type] to see only items that fit.
- Some bundles work across types; the UGC community targets R15 most often.
- Rthro bundles are sold as sets (head + body + accessories) — pieces designed to work together.
If body type isn’t working
- Item still won’t equip? → double-check your current body type matches the item’s badge.
- Rthro bundle looks wrong? → wear the full bundle, not individual pieces mixed with R15 gear.
- Can’t switch type? → verify your account is 13+ (younger accounts have avatar restrictions).
- Avatar reset to defaults? → it happens when switching; re-equip from Inventory.

FAQ
What’s the difference between R6, R15, and Rthro?
R6 has 6 joints and limited animations; R15 has 15 joints and full modern animation support; Rthro has 15 joints plus realistic body proportions in 4 shape variants (Normal, Narrow, Slender, Bulky).
Which is best?
R15 for most players — it has the widest item and animation compatibility. R6 if you want retro simplicity. Rthro if you want realistic proportions. The difference is aesthetic; none is objectively “better.”
Can I change my body type?
Yes, anytime from your Avatar page. Switching is free and reversible. Your items auto-sort by type — some may not equip until you switch to a compatible type.
Why won’t my item equip?
The item is designed for a different body type. Check the item’s description for its compatibility badge, then switch your avatar to the matching type.
Do experiences respect my body type?
Some do, some don’t. Many popular experiences force R15 for consistency. Older or retro experiences may force R6. You can’t override an experience’s forced type.
Do I lose items when I switch types?
No — your inventory stays the same. Items that don’t fit the current type simply won’t appear equippable. Switch back to your old type and the items work again.
Are Rthro bundles worth it?
If you want realistic body proportions, yes. Rthro bundles come as a themed set (head, body, accessories). They cost Robux and are usually 1,000-5,000 Robux per bundle.
