yes, the chairs will,

but someone seated on them may not sit comfortably dining.

Yes, that is actually a comfortable amount. It is 188" circumference. Each place setting should be approximately 24", so this would be a very nice arrangement.

I have a 60” table and keep four seats for daily use. I’ll use 6 when necessary but it feels crowded.

I have 6 chairs around a 54" round table. You can get 8 of those bistro chairs around a 60" table.

I have 6 large chairs around a 60" round pedestal table and they fit fine and it is comfortable for 6 people to use at the same time. I can squeeze a 7th chair in if needed. The specs for my chairs say they are 20.25" wide.
