The Madison Bay Company out of Pennsylvania markets reproductions of vintage china, mostly through museum gift shops. They make china that looks just like the antiques, but it is microwave and dishwasher safe. You can buy sets or purchase it by the piece.
I just found that you can get some of the pieces on Amazon.
My favorite is the Blue and White Pagoda pattern. It is a beautiful reproduction of traditional transferware.
The tray is 16″ long.
The tea pot that comes with the set is a tall traditional style.
A shorter, rounder tea pot is also available. It is 10 3/4″ handle to spout, 5 1/4″ high and 6 1/2″ wide.
I love the stylized handle.
The set comes with two cups and saucers. The cup is 4″ in diameter. The saucer is 5 3/4″ across.
You can buy additional cups, separately.
