Once you know the dimensions of the room and you are aware of the space required around the edge of the dining set, then you should think about the size of the table you need. This will depend on a few things, such has:
- How many people will use the dining set every day?
- Do you entertain on a regular basis?
- Will you be starting (or growing) a family?
- How much can you afford to spend?
Of course, not everything is set in stone and answers to some of these questions may change over time. A good general rule to follow is to buy a dining table that is at least 36 inches to 42 inches (91 to 107cm) in length.
Alternatively, you could purchase a folding dining table with extra leaves that gives you the flexibility to expand if needed. Folding dining chairs are also a good option, as these can be collapsed when not in use, maximising the space available in the room.
Also consider the amount of room each person will need to sit and eat comfortably. Allow for a minimum of 24 inches (60cm) of table space for each person. If you want to add in a little more elbow room you can extend this to 30 inches (76cm). Try to balance this out with the amount of people who will be regularly using the dining room table and chairs.
