I always recommend a variety of size options in any dining space to increase your ability to meet the needs of your guests. Yes it’s easy to put 2, 800mm square tables together to allow 6 people to dine in a group, however in my experience this inevitably means that the 2 tables don’t meet as they should. The ultimate outcome is that your guests become annoyed in their vein attempts to stop the “table wobbles”. I recommend the inclusion of 20% of the tables being 1200mm x 800mm to accommodate the larger groups successfully. Larger round tables are also an option however you should be aware that an 1800mm diameter table for example, will create an increase in chatter volume as people try to communicate across the table. A 1500mm size table is a good compromise.
