Field notes
Frequently asked questions
Does automatic mode always choose the best plan?
It chooses the orientation using less carpet area. Visibility, traffic direction, and manufacturer seaming rules may make the other plan preferable.
Why can a room smaller than the roll still have waste?
You purchase the full roll width for the required cut length, leaving an offcut beside the room.
Are closets included?
No. Measure closets and adjoining areas separately, then have an installer nest pieces into a complete cut plan.
