This depends on what style table cover and material you choose.
For cloth table covers in the looser table drapes and table skirts styles, the table covers will drape loosely around all four sides of a table. For fitted cloth table covers that are stitched to fit the exact size of a table, we offer both 4-sided and 3-sided options. We would recommend 4-sided option for cloth table covers as they tend to be more versatile in case you end up in a location where the table can be seen from all sides.
Vinyl table covers are typically 3-sided and wrap around the front, sides, and top.
