I recommend buying a rug that fits the size the table is kept at normally if you only use the leaves extensions twice a year try to take that into consideration.
Rug under coffee table size.
Don t be too funky and try to use round rugs with square tables leave that to the experts use a rectangular rug with rectangular coffee table and a round or oval area rug with a round or oval coffee table.
Living room rugs should fit under the couch and chairs.
Area rugs that are 4 x 6 feet or 6 x 9 feet are generally suitable for using under coffee tables.
Leggy furniture should have four on the floor or rug all dining chairs should be able to scoot in and out while staying on the rug.
To over simplify usually these sizes will suffice.
Bedroom rugs should leave a walkway on the sides of the bed.
For smaller living rooms you have two options.
Rugs should compliment your table or desk shape and size.
If you want to be confident that you re choosing the right area rug size for your dining room table simply add at least 60 inches to the length and the width of your table to get your ideal rug size.
To get the proportions right base the rug size on the interior dimensions of your seating area and not just the coffee table so it fills the negative space created by your furniture grouping.
6 chair dining room tables need an 8x10 rug.
Only a coffee table on the rug perfect for small or narrow spaces this layout plays off the room s scale to make it feel larger.
This is the minimum size you would want.
