Dining room tables come in various heights, but a standard dining table typically has a height of about 30 inches (76 centimeters) from the floor to the tabletop. However, there are variations based on the table style and design. Counter-height tables are taller, usually around 36 inches (91 centimeters), while bar-height tables are even taller, ranging from 40 to 42 inches (102 to 107 centimeters). When choosing a dining table, it's essential to consider the height in relation to the chairs or stools you plan to use to ensure comfortable seating for dining.
