Two pendants can look the same and sit very differently. The numbers tell you why.
Width
Aim for a pendant about half the width of the table below it. For a long table, hang a row of two or three.
Height
Hang 75 cm above a table and 90 cm above an island. Lower it for a cosy feel, raise it for an airy one.
Spacing
Leave at least a pendant's diameter between each light in a row.
