There is no single ideal patio size; it really depends on the situation. If you just want a patio for a small dining area, then you could get away with a smaller 12 by 12 foot patio. However, if you’re looking for a patio that can accommodate a full-fledged outdoor kitchen and dining area for guests, the size will need to increase accordingly. Professional patio design services can recommend the perfect size patio for your specific use case.
