Help us help you. Post pics of your living room and the room in question as well as any likes or ideas of what you think you like.

Hire a designer. If you can’t be bothered with a measured whole home floor plan, or any details of the space, or its surroundings, then you need to pay someone to drag all of the zillions of pertinent details out of you and do it for you. You don’t get massive design effort for free.

Verbo was harsh, Millworkman was kind. But yes, it hellps to know what the surround space looks like. Is this about the decorating of the space, or are you building and have larger questions? You might post in Home Decorating forum.

Consider a roundish table expandable with leaves. This helps with traffic flow visibly in an open plan space.

A basic floor plan and some pics of the adjoining kitchen and living room would be helpful.

Thank you everyone. I posted this super quick right before bed so I didn’t forget. But you’re right. I was more looking for what size rectangle table fits in a 10x12 space I guess lol but I forgot that a lot of tables can be expanded with leafs and what not. So my question may not be that relevant anymore lol

But we’re building a home in the next year. Just finalized floor plans. So just have random questions

10 X 12 is not a very large space for a dining table and chairs. No room for a hutch or other furniture. Do you have a small or no family?

My dining space is open to my foyer, kitchen, and dining room. It is 10'4" x 13'4" and I bought a 78" table extendable to 101.5". The 101.5" actually fits fine but I do not have a hutch or anything else in the space. If you only have 12ft, a 7 ft (84") table would probably be your max.

This is the table I bought:

my dining room is open concept. a little larger than that. no walls at all...

Width 42" W

Length 76" extends to 112"

A culinary degree or classes can do great things for a dining area.

Loads of info. on the Net.
