What black kitchen and dining room chairs should you get for a square table?

A square dinner table gives you flexibility regarding the chairs that you choose. If you want to have a formal dining room, it's still best to have either one or two arm chairs and two or three side chairs. This allows you to set the head of the table apart from the other positions. Otherwise, it's fine to go with four of the same chair design, regardless of whether you select arm chairs, side chairs, or Parsons chairs.

Which black kitchen and dining room chairs work well when you have a limited amount of space?

Owing to their lack of arm rests, side chairs and Parsons chairs are your best options if you want to maximize the number of places to sit at your dinner table. A good alternative to these for the sides of your table is a black bench. You may want to keep some folding chairs in a closet that you can bring out if you need extra seating. If you have more than enough seating and it's your dinner table that's too big, consider putting one end or side against a wall.

How much space is necessary between dining room chairs?

If you're using side chairs, then it's a good idea to leave a minimum of 6 inches between chairs and a maximum of about 12 inches. People sitting next to each other have enough room this way, and there aren't any oversized gaps between your chairs. You can get away with a little less space between arm chairs if you elect to put two or more of those next to each other.
