54”-72”, counter to counter. It depends if it’s a traffic path, major traffic path, or if people just want to squeeze through occasionally to reach a seat. That in no way appears to be close to 78” of space between the two. You need to be working with something that uses scale sizing.

Thanks. It’s a SketchUp drawing, I assure you the scale is right, just the chairs are mostly pulled out.

IMO 60 -72” is good .

If you ever have both the breakfast bar and dining table in use at the same time you need space for all the chairs at both locations to be filled with adult-size bodies, room enough for pulling chairs out to sit on and scoot back toward the table, and plenty of room for a person to walk in between all those occupied seats without bumping into anyone. Allow two feet of space for each seated adult plus the chair itself and a three-foot walkway for a person carrying a plate and a drink between occupied chairs. 72” would be tight if anyone is larger than average. I’d keep it at 78”.

I have 64” but my chairs tuck under the island, it’s a mile of space. I agree with the 60”-72”
