Expert Tips for Choosing the Right Size
📏 Measure Your Space First
Before you start shopping, measure your living room carefully. Note the width and depth of the area where you plan to place the sectional. Don't forget to account for doors, walkways, and other furniture in the room. A good rule of thumb is to leave at least 18" of walking space around your sectional.
Consider Your Room Layout
- Open Concept: Use the sectional to define different zones
- Small Spaces: Choose a compact apartment-size sectional with a smaller footprint
- Large Rooms: A U-shaped or oversized L-shaped sectional creates a cozy focal point
Match Your Lifestyle
- Entertaining: Choose a larger sectional with plenty of seating
- Family Spaces: Durable fabrics and easy-to-clean materials are a must
- Relaxation: Consider a sofa with a chaise lounge for ultimate comfort
Check Doorways & Stairways
- Measure your doors: Make sure the sectional can fit through doorways
- Modular options: Choose a sectional that comes in pieces for easier delivery
- Delivery access: Consider whether the sectional can be delivered to your home
