Your seat.
Your lens. Your frame.

Distances are horizontal: tier elevations, people, rails, stage height and obstruction are not modelled. Markers do not snap to actual ticket numbers.

The 46 m reference comes from Seoul’s renovation announcement; it describes the expanded floor. The drawing’s retractable-seat configuration may differ. You can change the reference above.

Framing uses an ideal rectilinear projection: frame height = distance × sensor height ÷ focal length. The singer is a scale illustration, not a photograph or a rendered seat view.

Seat coordinates and distances are approximate. Framing assumes an uncropped image; head-to-waist height is estimated as half the singer’s height.
