Another benefit to placing a carpet beneath your desk is it can help your office feel more ordered and organized. Rugs enhance desks and draw your attention toward them.

Keep in mind, if you own a rolling desk chair, then your carpet should be on the thinner side. A rolling desk chair might catch in thick and shaggy carpet strands and prevent you from rolling.

For non-rolling desk chairs, feel free to use a fun and fluffy carpet. Remember to lift the chair and not push or slide it. This will prevent the desk chair legs from getting snagged in the carpet strands and accidentally shredding your lovely carpet.

What Size Rug Should Go Under an Office Desk?

The rug size that should go underneath your desk depends on your desk type and desk size.

In the fashion world, the general guiding principle for rugs underneath desks is that your rug should be at least 18” to 24” larger than the desk size. A carpet this size will leave ample room for your office chair.

If you have a corner desk and round carpet, center your carpet to the center or corner of your desk. Make sure to leave enough room for your chair to rest on the carpet.

Rotate a rectangular rug to sit in a vertical position for smaller-sized offices. There will be more carpet material where your chair sits and in front of your desk. This is a terrific rug arrangement for visitors that sit in a chair across from you.

For rectangular rugs, you can have your carpet flow lengthwise along with your desk or in a vertical arrangement for narrow offices.

For circular carpets, they are most appealing when centered with your desk. Pull a round carpet beneath your office chair for a better fit and more aesthetic look.
