Body Proportions

Make sure you have proper mounting before doing this as it will influence your results: mounting page

You can visualize your body proportions here btw: visualizer page

You can use a mirror in VRChat to see your trackers' positions. However, compare SteamVR tracker position to IRL joint's position, not your VRChat avatar's joints positions.

Alternatively, you can use the SlimeVR Overlay in SteamVR to visualize your bones.

Make sure to adjust the values from the top-down.

Head shift (8-12)

Shake your head left to right as if you're disagreeing. Adjust your head offset until any movement is be negligible. All trackers should stay in place.

Neck Length (8-14)

Move your head up and down as if you're nodding OR move head side-to-side as if you're confused. Adjust your neck length until any movement is be negligible. All trackers should stay in place.

Chest Length (25-40)

Modify value until your SteamVR chest tracker is about at the middle of your spine

Hip Length (2-6)

Feel free to experiment with it, but keep it around 2 to 6

Waist Length (20-35)

Modify value until your SteamVR waist/hip tracker lines up with your hip bones (you can use your controller to line up your IRL hip and tracker).

Upper Leg Length (35-60)

Modify until your knee trackers are at your knee joints.

Lower Leg Length (45-60)

Modify until your feet trackers are at the level of your ankles.

Feet (when using feet extensions)

Set “foot length” at 0, change “foot shift until feet trackers are inside your avatar's ankles or at the same level horizontally and set “foot length” back to 5.

Hips width (26-32)

Default value is good. Can try to tweak to make your leg trackers line up when resetting, but do not increase in the goal of preventing leg crossing.

Hip offset (0) and Chest offset (0)

Keep at 0 unless you have a particular problem with your avatar.

Skeleton offset (0)

Keep at 0 unless you have a particular problem with your avatar/setup/viewpoint.

Controller distance z (10-20) and Controller distance y (2-8)

Rotate wrist and adjust until elbow tracker has the least amount of sliding.

Upper/lower arm length (20-35)

Adjust so that SteamVR tracker is on your elbow.
