Placement Guidelines

Position your rug correctly for the best look.

Do This

  • Position rug so 2/3 extends from under the bed toward the foot
  • Center the rug with the headboard, not the room
  • Account for the extra 4" of bed length when positioning at the foot

Avoid This

  • Don't center the rug in the room (center it on the bed instead)
  • Don't treat it like a standard king—the Cal King is longer and needs more coverage at the foot
  • Don't let the rug end at the headboard—it should extend well past the foot

Pro Tips

  • 1Position rug so about 12" extends under the headboard
  • 2The extra 4" of length vs standard king needs consideration at the foot
  • 3Nightstands should sit on the rug for best results
  • 4A 10×14 gives you extra breathing room for the longer bed

For most Cal King bedrooms, a 9×12 rug is the standard choice. The 12-foot length handles the extra bed length well. If you have a larger room or want maximum coverage, consider a 10×14.
