When arranging a loveseat next to a sofa on a patio, deck, or garden space, allow enough room between the two pieces for easy walkways and conversations. A good rule of thumb is to leave about 2-3 feet between the outer arms of the loveseat and sofa. This gives a comfortable amount of clearance so people can easily get in and out of the seating without bumping knees or feeling squeezed. Positioning the loveseat and sofa facing each other with a patio table in between also works nicely to promote social interactions while keeping the furniture functional. Just be sure there's enough room around the table so people don't feel crammed. Loveseats and sofas used in separate conversation nooks around a fire pit or facing views work well spaced 6 feet or more apart depending on the area. Most importantly, leave breathing room to lounge freely while navigating between pieces with ease.
