it's not mandatory. either way looks good.

but if you did, I think these would look nice

I like the coloring in this one w/your dark wall

not the blue, just showing you a similar table w/dark wall. you'd pick one w/gray or charcoal in it

Measure off a rectangle 6 feet longer and wider than your table and tape that out around it with painter's tape. Does the tape run into the baseboards, floor vent or any furniture you may have on the walls not shown? If not, that's the size you need. Don't go any smaller than that or the chairs will fall off it when pulled out and sat in. The photo makes it appear that your wall installation and drum light are centered with the wall but not with the table. If true, I would adjust for that and remove the chairs and bench before taping and measuring.

I would do a blk/wht to match ur pics.

Yes rug. And I say a lighter color. Close to the table. Like the two middle options Beth showed

Gorgeous room by the way. Really pretty

Really depends on your family and day to day use. I would love a rug but don’t want to deal with the chaos of a rug and three kids and a golden retriever. So we’ve settled for no dining room rug. There is design and then reality.

What does the rest of the room look like?

Also, can you please show us your entire window there?

The curtains look way too long, but it is possible that you have hung them too low, and by hanging them higher they will be the perfect length.
