Sofa Size Calculator

The Two-Thirds Rule

A general guideline is that your sofa should be about two-thirds the length of the wall it's placed against. This creates a balanced look and ensures the sofa doesn't overwhelm or get lost in the space.

Room Size Considerations

• Small rooms (under 150 sq ft): Consider loveseats or apartment-sized sofas (58-72 inches)
• Medium rooms (150-250 sq ft): Standard sofas work well (72-84 inches)
• Large rooms (over 250 sq ft): Large sofas or sectionals (84+ inches)

Spacing Guidelines

• Coffee table distance: 14-18 inches from the sofa edge
• Walkway clearance: At least 30-36 inches for comfortable passage
• TV viewing distance: 1.5-2.5 times the TV diagonal for optimal viewing
• Wall clearance: Leave 6-12 inches behind the sofa if possible

Sofa Depth Matters Too

Standard sofa depth ranges from 30-40 inches (76-102cm). Deeper sofas are more comfortable for lounging but take up more room space. Consider how you'll use the sofa - formal sitting or casual relaxing - when choosing depth.

Before You Buy

• Measure doorways, hallways, and stairwells to ensure delivery is possible
• Use painter's tape on the floor to visualize the sofa footprint
• Consider the sofa's arm style - track arms save space vs rolled arms
• Account for reclining mechanisms if choosing a reclining sofa
• Think about future room changes and flexibility
