Choosing the right table size depends on your room’s dimensions, the number of people you’d like to seat, and traffic flow. Measure your dining area, allowing at least 36 inches around the table for comfortable movement. For seating, each person generally needs 24 inches of space along the table. A rectangular table works well in narrow spaces, while round tables are great for smaller, square rooms. Extendable tables offer flexibility for entertaining. Visualize different sizes in your space with tape on the floor, ensuring you’ll have enough space for chairs and easy movement.
