* Small Dorm Room (under 100 sq ft): A 5' x 8' rug is usually a good choice. This size will fit comfortably under most beds (especially twin XL) and leave some floor space around the edges.
* Larger Dorm Room (over 100 sq ft): You might consider a 6' x 9' rug or even an 8' x 10' rug, depending on the space and your furniture arrangement. A larger rug can make the room feel more spacious and luxurious.
Important Considerations:
* Bed placement: If you want the rug to go under your bed, measure the bed's dimensions and add at least 2 feet on each side to allow for some floor showing.
* Furniture arrangement: Consider where your desk, chairs, and other furniture will be placed. You want the rug to anchor your furniture arrangement, not make the room feel cramped.
* Door clearance: Ensure the rug doesn't obstruct the doorway.
* Style: Consider the overall aesthetic of your dorm room. A larger rug will make a bigger statement.
Instead of focusing solely on square footage, visually assess your room and furniture placement before making a purchase. It's often better to slightly underestimate the size rather than overestimate and have the rug feel overwhelmingly large in a small space.
