All of the tables listed below are the largest extendable dining tables available that are not completely custom. These tables can be extended with upwards of 12 and 13 leaves. Each leaf is 12 inches wide making the largest of our tables 19 feet long, Standard. At this length you can seat 20 to 22 people. Many people have concerns about seeing a line between each of the leaves, especially when you add 12 or 13 of them. Our builder takes great pains in making sure that the leaf joints are practically invisible. Each table is sanded with all the leaves that you order in them. Not only but the leaves are numbered so that you can place them back in the table in the same way everytime thereby keeping the leaf joints seemless. Because the leaves are sanded in the table you will want to order all the leaves that you may need. If you dont and you end up needing more it will be just about impossible to make it fit perfectly with the rest of the leaves
