If you want anything on the leftDo you like plants? And I agree above try that and if that don't work then leave it the way it is cuz you're doing good

This is a “budget? What’s a budget?” answer…but I’d be tempted to line one wall with a banquette which would shift the table over and out of the middle which would give you the opposite wall for some type of buffet or console table.

The rug is accentuating the narrowness…i would consider a rug ..more wall to wall…even with a pattern that leans more toward parallel to windows…also try moving the drapes wider..to barely cover window frame…placing the bench under the window and pulling the table forward a little…and if the budget allows smaller wooden “country style” chairs would give the space a little more breathing room…

Your room is average, not narrow.

Some fine-tuning

Add more panels of drapery and run them to the corners of the wall.

A chandelier that was sized correctly for the room would help.

Those two things will change the appearance.

Additionally, I see you have selected formal, large-scale chairs for the room and a farmhouse kitchen table. I would change that out to a table that is at least 42" deep.

Have you tried turning the table then you might have space for a buffet on the window wall with a nice lamp on it. It would help to know the exact size of the room and I agree the table does not work with the chairs . The pics to me look skewed so a to scale flor plan would be better and also the size of the table you have.

The only pieces I would keep in the room are the chairs and the chandelier. I suggest no rug at all (is is emphasizing the narrowness). I suggest no draperies; use each side of the windows for shelving. Keep the blinds up during the day. A round table might work better for you and I would not do wood.

No art on either wall. Let the window and new shelving be a focus.

I agree with Beverly, the only additional points would be to remove the bench which is just clutter and remove the chair rail (visual clutter)
