When choosing dining room chairs, consider the table’s height, style, and available space. Chairs should be 10-12 inches lower than the tabletop for comfortable seating. For a cohesive look, match the chair design to the table’s style—rustic, modern, or traditional. If the table is round, consider armless chairs for space efficiency; rectangular tables can accommodate chairs with arms. Ensure enough space (24-30 inches) per chair for easy movement. Mixing materials or colors can add visual interest, but ensure they complement the overall décor.
