How low should a pendant hang over the dining table? Drag it and see

The light over your dining table works best when its shade hangs roughly 60 to 90 cm above the tabletop, measured to the bottom of the shade, not from the floor.

Too low and it blocks faces and glares. Too high and the pool of light spreads thin. Drag the lamp in the side view, change the ceiling height and shade, and see the sightline and cord length update.
