You need a minimum of 24 to 36 inches from the wall to the front of the table. If you have a counter on the other side that will have stools, your table should be 48" minimum from the counter top. No stools, minimum of 36"I do not put stools backing up to chairs. Too many legs, hit each other.

Chandelier should be 30" off the table top.

@Diane Kremer My benches will be up against the wall with cushions along the back. So you're saying my table should sit 5-17 inches from the benches?

Marianne, The question is more complex than that. When you have a bench and the dining table, you have to have enough room to get in on either side as the table overlaps the bench. Also, with the 1.5" sill, back cushions and a 19 inch bench, you do not have enough seating space. You also have the door to the right of the table which may be blocked if you move the table out too far. These are all things that need to be considered before you put your bench in. Your bench should be at least 24 to 26 inches deep. Have you given any thought to an L-shaped bench so you could slide in on either side? If you pull your chair up to a table as if you were sitting there to eat, you will notice that the table overlaps the bench. That is how you place the table with your bench. So you can see you need room to get around or into it on either side. I hope that helps.

Visit http://www.homestyler.com/ . The site is free but, has limitations with furniture, accessories choices etc, But it will give you an idea if everything will fit the way you want. I'd wait until you have your benches installed before moving any other more permanent items.
