Placemats - rectangle or square - which ones work best??

[DorsetLass]

Advice please- I am aware this is not the most important of decisions that I will my like but...about to get some slate placemets for our large rectangular oak table. Thank you for help on such a trivial matter!

We have rectangular (same slate for oak table!) Just prefer the look!

You'll be able to fit more square ones on so that might be better if you'll ever need to squeeze loads of people at the table. but I prefer rectangular aesthetically.

Rectangular for us too.
