When planning space for a recliner sofa, consider both its regular and fully reclined positions. A standard recliner sofa usually needs at least 1 to 2 feet of clearance from the wall to recline fully. If you have limited space, look for wall-hugger recliners that require minimal clearance. Also, measure your room dimensions and ensure there's enough space for foot traffic when the sofa is extended. Proper planning will prevent crowding and allow comfortable movement around your living area.
