What do you mean by pretty ? What is your style ? Your idea books are not very helpful.

For 6-8 you will need a 60" round table, but the final number of chairs will depend on the size of the chairs you have. I have a 60" round table in my breakfast area with large chairs. It fits 6 of the large chairs comfortable and I can squeeze in a 7th if we have a large group and need extra seating.

What style table?

My table is from Theodore Alexander. Good quality and has been very durable with kids.

My style is very southern chic with white walls, dark floors, accents of gold. Looking for furniture currently. Thank you.

@BeverlyFLADeziner Thank you! I absolutely love that first table!! ❤️
