Post a floor plan noting all dimensions, including doorways, windows, fireplace, etc.

Anyone can throw out a number or shape and say that should work. But I’d lay down sheets or cut up boxes, etc. to approximate sizes and then move all around the pretend table you’ve crafted…chairs in and chairs out, walking around to get from one room to another, carrying a large platter with the thanksgiving turkey on it, etc. then you’ll get a better feel for how much room around the table you’ll want which then gives you a much better idea of the size and shape of a table you’ll be comfortable living with.

Can you also post pics from other angles? I think a round table in a rectangular room won't work, just based off the info you've provided so far.

I need a lot more info and honestly that FP looks silly in that space and I see nothing to say historic and are the drapes staying. ? A room is more than just size tou styrl, how many seats you need how traffic flows through the space all have a real bearing on decor. Start with a to scae floor plan showing every window, doorways where those lead and every measurement post that here in jpeg format in a comment DO NOT START another post or we will lose you . Als include the rooms next to this one For mw the first thing would be total redo of thea FP it looks like a kids toy

Yes, Patricia, that fireplace is totally out of proportion--it looks to be about 2 feet high, while the windows and ceiling look 4 or 5 times that. I wonder if it's real or photoshopped.

I have no idea but it has to go and if photo shopped even worse . The home is apparently historic and the drapes look like some faric tossed up there with no thought We need actul pictures please if these are not it /I need much mor einfo. Early for answers form the OP .

Regarding help with furnishing, what is the style you are aiming for/suiting adjoining rooms? Perhaps pour over inspiration rooms for ideas and/or provide more details to receive more relevant suggestions: changing window treatments, painting, want a rug, open to modifying the fireplace, etc.

Measurements, plus do the following:

Here is how to post a Design Dilemma to get the best results. You need to show the whole space—all four sides of an entire space—even if it’s about one specific Dilemma. Commenters need to see doorways, windows, closets, finishes throughtout the space to make informed suggestions.

State right at the beginning what the room will be used for and who will use it. State the non-negotiables at the beginning, what has to be kept. Give some idea of the budget. And provide approximate measurements

Keep in mind that you're inviting some design pros and people with a design eye into your home via photos. If they walked into your actual space, they would take in all of it: all four sides, doorways, floors, windows, ceiling, built-in fixtures, lighting, trim--the "givens"--then the features that can be changed--furnishings, paint, art, rugs, decor items, etc. It's all one first impression. Same thing with photos. That's why it's important to provide well lit photos of the entire space, taken from all sides of a room regardless of the size of your problem.

Start by removing the drapes

In a long, narrow room, which is what your room looks like to me, you don't want a round table. I'm also not a fan of the drapes and they look like they are hung much higher than the top of the windows, making the window on the left look very small.

I'd probably start by getting some art for over the fireplace. You want the proportions to be right, ie more or less the same proportions as the space.

As for the size of the table, none of us can tell without the measurements of the room and knowing your needs. Do you want to fit all 20 members of your extended family around it at Thanksgiving? Or will you it only be you and your partner?

Thanks for the comments. Attached is a photo of the dining room decorated by the previous owners. I'd like to find a table that seats 8-10.

The fireplace definitely has to be dealt with but look at just a minor adjustment already improves the look by replacing those dark print curtains and removing the mantel...

With windows this tall, selecting drapery panels that have hold backs higher up help not add to the visual height of the room.

An oval would not be a shape I considered for this room.

Just saw new pictures were posted above, definitely looks better proportion wise.

The additional photos show a much better proportioned fireplace.

We still need a floor plan with all dimensions noted. See housegal200's comment above.
