There are no rules that say certain rooms cannot have large or oversized pendant lighting. As a general guideline, the pendant size should complement the room around it, matching in size with other prominent objects such as a dining room table or a sectional. To determine this, make sure to measure the height, width, and diameter of the pendant desired. Bedrooms and living rooms tend to be the largest rooms of the home and can be home to oversized pendant lighting, however, consider how much traffic each room receives and if the pendant in mind is an elegant piece that would be better suited as a focal point in rooms guests will spend more time in. A rustic modern pendant can be a conversation piece that stands out with natural textures and a warm feel.
Also keep in mind the proper hanging height for pendant lights. Pendants that hang too high or too low can have the opposite or diminished effect as intended and may overwhelm the room instead of creating flow. The average ceiling height is 8 feet, so keep pendant lights hanging 24 to 36 inches above any surfaces. If the pendant is set higher than 36 inches, the intention of a more focused glow may not be achieved and a linear suspension or chandelier may be a better option.
