Short answer
Count the people who eat there most weeks, not Christmas.
Four people: 63 in. Six: 94.5 in. Eight: 110 in. Those are our published ratings on Ann, deliberately generous so chairs with arms still fit. A generic 24 in-per-chair chart can squeeze more onto the long sides; we would rather you sit well.
If the household is four with guests once a month, 63 in plus the two ends (six) on a 35.5 in-wide table is the purchase. If guests are the point of the room, buy 240 or 280. Do not buy a 160 and hope it grows.
Yes, one chair at each end, if the table is at least 35.5 in wide and the legs leave knee room.
Ann is 35.5 in deep. Legs sit 4.9 in in from the short ends, so a chair can go between them. That is how a 63 in Ann becomes six seats without magic.
Diana and Ann can be made in a custom width. About 35.5 in is the comfort tip if chairs sit on both long sides. Narrower is possible; it is a recommendation, not a verdict.
There is no leaf, no butterfly, no hidden extra 31.5 in.
The search is real. The product is not. Custom length on Ann is a made-to-order table at a fixed size, not a mechanism. If you need two lengths in one life, you need two rooms or a second table, not a slide.
Ann's stated depth is 35.5 in. That holds two place settings and a dish in the middle.
If the room is a galley, custom width on Ann or Diana is the lever, not a shorter length that costs seats.
Luna is 43.5 or 55 in across, still 30 in high. Four seats at 43.5 in, six at 55 in with our dining chairs. The round size guide is its own page.
About 24 in wider than the table on every side, so a chair pulled out still has all four legs on the rug.
That makes 9 x 7 ft for a 63 x 35.4 in table, 12 x 7 ft for 94.5 x 35.4 in, and a round rug of about 7.5 ft for the 43.5 in Luna, or 8.5 ft for the 55 in one. If the room cannot take that, go without: a rug that catches the back chair legs is worse than none. Choose a flat weave or short pile so chairs slide.
