Pedal & wheel reach distances for your sim rig, from your body proportions
ERGONOMICS // LIVE
Reference point: every distance below is measured from your hip point — where your hip crease sits on the seat base. Pedal height is computed close to this hip point (per the "in line with your butt" rule), with small variation based on your own thigh-to-shin proportions. In practice, use whatever fixed part of your rig the seat mounts to (the seat rail zero, or the front bolt of the seat slider) as your physical zero, and measure forward along the same rails your pedals and wheel actually slide on.
Body
Limb lengths are estimated from your height using standard body-proportion ratios. Switch to "Enter measurements" for a more precise result.
Body measurements
Fit targets (fixed baseline)
This tool doesn't let you dial in seat angle or joint angles — it works the other way around: your body measurements go in, and the correct seat angle, pedal position, and wheel position come out. The targets below are fixed for everyone and drive that calculation:
Hip angle (back-to-thigh): 90°
Knee angle at full pedal press: 132°
Elbow angle with wrist on the wheel: 45°
Seat & pedal shape (reference)
These describe the physical hardware rather than your body, so they're not computed here — treat them as what to look for or set on the rig itself: seat lumbar bolster around 52° from horizontal, curving to about 44° higher up the backrest; pedal face tilted back about 12° (top pointing up/back); wheel dish angle around 14°.
Contact offsets
Small additions for the ball of your foot on the pedal face, and your grip point on the wheel rim.
Rig floor reference
Measure from the floor to where your hip actually rests on the cushion. This is rig-specific (depends on your seat mount height), not something derived from your body — it's what turns the hip-relative distances below into actual floor heights.

Recline-independent — pure elbow-angle geometry. Use the forward-of-hip figure above for actual rig setup.
Rig outline is a schematic Simlab GT1 Evo-style layout for visual context, not a precise spec drawing — the figure's size and reach change with your body proportions, but treat the numbers above (not pixel measurements from this drawing) as the source of truth.
How to set up your rig
Sit in your seat. Find your hip point (see reference note above) — that's zero for every measurement here.
Recline your seat back to — from vertical (target: 32–34°). This also sets your thigh angle, since your hip angle is fixed at 90° in this model.
Slide your pedal plate until the pedal face is — forward of your hip point, at the pedal height suggested below, tilted back about 12° (top pointing up/back).
Position your wheel so the rim (where your wrist rests) is — forward of your hip point, at a height where your hands land level with your shoulders, with the wheel dished back around 14°.
Get back in and sanity-check: at full pedal press your knee should sit near — (target 132°), and with your wrist on the wheel your elbow should sit near — (target 135° at the joint — a 45° bend away from straight). If either feels off, nudge the seat fore/aft slightly rather than re-measuring from scratch.
