To obtain the size round tablecloth required for your round top barleaner table -

Measure top to floor (double this measurement) and add diameter of the top. Choose either your exact cloth size or slightly larger (extra fabric can be tucked underneath to create a fuller effect).

OR use a 3.3m round tablecloth with a chair sash to gather fabric around the centre pole and allow fabric to spread out to the floor.
