How big a table fits my room?
Take 42 in (3.5 ft) off each side of the room, or 36 in (3 ft) if nobody needs to pass: what is left is the biggest table. A 12′ × 14′ room minus 7 ft each way leaves 5′ × 7′, so a 40 × 84 in table seating 8 fits. The calculator does this for your room and shows the clearance as a dashed outline.
