What Is a Tablecloth Size Calculator?
A tablecloth size calculator tells you the exact dimensions of cloth you need to cover a rectangular table while leaving an even overhang on every side. Instead of guessing and ending up with a cloth that puddles on the floor or barely reaches the edge, you enter your table's measurements and the drop you want, and the tool returns the finished length and width.
How to Use It
Measure your tabletop's length and width in inches. Then decide on the drop — the amount of fabric you want hanging over each edge. Common drops are 6–8 inches for casual everyday use, 10–12 inches for a more formal look, and a full floor-length drop (often 28–30 inches) for special occasions. Enter all three values and read off the recommended cloth size.
The Formula Explained
Because the drop hangs over both opposing edges, you add it twice to each table dimension:
$$\text{Cloth Length} = \text{Table Length} + 2 \times \text{Drop}$$$$\text{Cloth Width} = \text{Table Width} + 2 \times \text{Drop}$$The factor of 2 accounts for the overhang on each of the two opposite sides.
Worked Example
Suppose you have a dining table that is 60 inches long and 30 inches wide, and you want an 8-inch drop. The length becomes \(60 + (2 \times 8) = 76\) inches, and the width becomes \(30 + (2 \times 8) = 46\) inches. So you would buy or make a 76 \times 46 inch tablecloth.
FAQ
What drop should I choose? For everyday meals, 6–8 inches looks tidy. For dinner parties, aim for 10–15 inches. Floor-length drops are reserved for formal events and event tables.
Does this work for round tables? No — this calculator is for rectangular and square tables. For a round table, the cloth diameter equals the table diameter plus twice the drop.
Should I add extra for hems? If you are sewing your own cloth, add 1–2 inches per side for a hem before cutting.
