Round, 60 inches. Rectangle 6 x 3 . Allow 12 to 18 inches for chair, and another 12 to 18 inches for the pull back. Good luck!

Also take a look at Room and Board....they have several tables with different wood finishes or wood/steel/metal bases and a good selection of various tabletop materials. Also if you prefer a wood table, an area rug underneath the table could also help to break up all of the wood too.

Wax is good on a dining table as easy to apply a bit more in the event of cup rings etc.

Hi Jennifer K, thanks for your comments. The photos you have posted are really lovely but not really suited to our environment and house, which I know is impossible to tell from one photo. We have built a modern farmhouse on 10 acres. That room looks out to beautiful green countryside and the river below. The dining room is a bit of a feature and is completely different to the rest of our relaxed lodgey style house but I don't want it to be too modern, if that makes sense. The photos have given me a few ideas so thank you so much for your help!
