So after trying to find a new floor lamp, and look at tripod floor lamps. I saw a few modern designs which I liked, but then looking closely I realised that they are actually different heights. I sort of overlooked the fact that there may be different heights and that can make a difference in a home. For example, some who may have talk ceilings may prefer taller floor lamps.
When is comes to the height of floor lamps for sofas. The top of a floor lamp that is going to be used with a sofa, should be between 58 and 64 inches tall.
The bottom of the shade should be at or above the eye level of a person seating down on the sofa.
If you want to use a combination of floor lamps and table lamps, then make sure that the top edges of all the fixtures are within a few inches of one another.
