What is the standard height of a lamp?
Average floor lamps range in height from 60 to 72 inches, or 5 to 6 feet, but there are much taller lamps; think of those that arch over a sofa, almost brushing the ceiling, or a spring pole lamp that goes from floor to ceiling.
What size should a table lamp be?
Overall lamp and table measurements: The lamp should not be more than 1.5 times taller than the surface it is sitting on, and the lamp shade’s diameter should be smaller than the width of the sofa side table. You don’t want the table lamp’s shade to be sticking out beyond the table’s edge.
