Measure your table. Determine how many additional inches you want on each side.
Add the extra inches to your table's present dimensions to find out how big your extension should be. For example, if you may want to add 12 inches to a 60-inch-long table and 8 inches to a 48-inch-wide table, you would look for a table extension measuring 72 inches by 56 inches.
Look for an extension that is as close to your dimensions as possible. Make sure you select a table extension specifically labeled for that use.
These pads are sometimes called expanders.
Clear off your table, and unfold the extension on the table. The pad should be centered on the table, with the extra inches hanging evenly off each side.
Adjust the pad as needed. If the extension is extra long or wide, connect the extension legs to the ends.
Each extension is different. Consult the instructions to see how the legs for your particular extension go on.
Gently press on the ends of the extension to test for stability. Use it only if it can take the pressure.
if it's sturdy, cover the extension with a tablecloth.
