To find the right tablecloth size, measure your table's length and width (or diameter for a round table), then add twice your desired drop to each dimension. The drop is how far the cloth hangs over the edge: 6 to 12 inches is right for everyday dining, while 15 inches to floor-length suits formal occasions.
The simple formula
Start by measuring your tabletop. For a rectangular or square table, measure both the length and the width. For a round or oval table, measure the diameter at its widest point. Then decide on your drop and double it, because the cloth hangs over two opposite edges. The math is straightforward: tablecloth length equals table length plus twice the drop, and tablecloth width equals table width plus twice the drop.
Choosing your drop
The drop sets the mood of the table. A casual, everyday drop of 6 to 8 inches is practical and relaxed. A more polished drop of 10 to 12 inches suits dinner parties and looks elegant without getting in the way. For formal events, weddings, and holidays, a dramatic 15-inch drop or a full floor-length drop of around 29 inches creates a luxurious, occasion-worthy look.
A worked example
Suppose you have a rectangular table that is 60 inches long and 40 inches wide and you want a 10-inch drop. Add twice the drop, or 20 inches, to each dimension. You need a tablecloth roughly 80 inches long by 60 inches wide. For a 48-inch round table with the same 10-inch drop, you would want a cloth about 68 inches in diameter.
Don't forget the leaves
If your table extends with leaves, decide whether you want a cloth sized for the table closed or fully extended, and measure accordingly. Many hosts keep one generous cloth sized for the extended table for gatherings, and a smaller everyday cloth for daily use.
