  • Room size and layout
  • Number of people using the sofa
  • Existing furniture placement
  • Doorways and hallways for delivery
  • Personal comfort preferences

Room Size Considerations

I made the mistake of not properly measuring my living room before purchasing my first sofa. The result? A beautiful piece that overwhelmed the space. Here’s what I learned:

  • Leave at least 30 inches of walking space around the sofa
  • Consider the distance from the sofa to the TV (8-12 feet is ideal)
  • Account for coffee tables and other furniture
  • Remember to measure doorways and staircases for delivery

Tips for Measuring Your Space

Here’s a practical guide I developed through trial and error when measuring for my new sofa:

  • Use painter’s tape to mark the sofa’s footprint on the floor
  • Measure twice, order once
  • Consider the sofa’s depth for comfortable seating
  • Account for armrest width in your measurements
  • Remember to measure ceiling height for tall sofas

Based on my experience and research from Architectural Digest and Consumer Reports, here are the most common mistakes people make when choosing sofa size:

  • Not considering the scale of other furniture
