The usual rule for rugs in rooms is made of that you must fit the size to that of the table. Chairs stay on the rug when you push them back from the table. Like this all four feet stay on the rug when some pull the chair to get in or exit.
A rug that extends in 24 inches past the edges of the table keeps dining chairs from feeling loose or shaky, the front feet stay on the rug while the back are on the floor. That protects also the floor and makes everything more comfy.
How to Size a Rug for Your Dining Table
To find the right size, measure first the dining table with any leaves. Good advice is to choose a rug that is 18-24 inches wider than the table on all sides. You can simply add around 24-30 inches to every side.
Measure the length and width, later add 24 inches to each side… That means plus 4 feet to length and width, so 2 feet extra for every side. For a rectangular table adding 48 inches to length and width gives the least size for good support.
An option is to add 36-48 inches to the whole table size, to leave space to move the chairs. Some suggest 60-80 cm of space around the table.
Different tables need different setups. A standard 60-inch table for six people works well with a 10×10-foot rug. A 48-inch round table best goes with an 8-foot round rug.
A 60-inch round table usually needs a 9-foot option. For a table for four people an 8×8-foot rug works well, whether round or square shape. A two-seater table can use a rug of around 4×6 feet.
A standard rectangular six-seater dining table needs bigger, like a 6×9-foot or 8×10-foot rug. For a typical 36×72-inch six-seater table you should use an 8×10-foot carpet with 24-inch space on all sides. A large table for eight people best goes with a 9×12- or 8×10-foot rug.
To avoid bumps, adding at least 24 inches to all sides is wise.
