What size rug should I buy?
Choose the room and enter the measurements that actually control rug size. SizeDial turns the layout into a standard rug size you can shop for.
How SizeDial calculated this
Dining-room results use the published 24-inch extension guideline around the table. Bedroom and living-room results map common furniture-placement goals to standard rug sizes and are presented as practical layout recommendations rather than universal rules.

A rug should relate to the furniture, not just the empty floor.
For dining rooms, chair movement is the key constraint. Lowe's recommends a rug that extends at least two feet beyond the table on every side. Living rooms and bedrooms have more than one valid layout, so the calculator shows a practical standard size and tells you what placement assumption it used.
Dining room rugs
Measure the table, then allow room for chairs to remain on the rug when pulled out. That is why dining rugs often need to be larger than people expect.
Living room rugs
A common approach is to put the front legs of the seating on the rug. Larger rooms can use a bigger rug with more furniture fully on it. A floating rug with no furniture legs on it is primarily decorative and should not be mistaken for a room-anchoring rug.
Bedroom rugs
The rug should extend far enough beyond the bed to give you usable rug underfoot. Standard 8×10 and 9×12 sizes are common because they work with many queen and king layouts.

Rug sizing FAQ
What if my room is between two standard sizes?
Use furniture placement as the tie-breaker. A slightly larger rug usually anchors a seating or dining group better, but leave enough visible floor and clearance for doors and vents.
Do exact rug dimensions vary?
Yes. A rug sold as 8×10 may differ by several inches. Verify the product's listed actual dimensions before buying.
