Some rules just make things better! Like traffic rules. We all get around a little easier because of them. Similarly in the home there are some general dimension rules for furniture distance that make a room feel and look better and indeed allow for better foot traffic flow.
Apartment Therapy makes a case for sticking to the rules in this link…

Apartment Therapy gives a general range for the optimal distance of a chandelier over a Dining Room table. Another tip is that a smaller chandelier should hang higher over a Dining Room table -
While a larger one should hang lower, closer to the table -
In addition, larger scaled rooms or furniture look better with more generous spacing in some areas, like walkways.
Keep walkways open for free movement within and between rooms, a minimum width of 36 inches when possible. If you’re thinking rules, rules, rules! Here is one you can break. If there’s a natural path that leads from the Front Entry immediately to a back door, break that up with a centering table or sculpture, something delightful that encourages you to linger and enjoy your beautiful home before rushing right back out!
