Furniture footprints and material costs are typical planning estimates, not exact measurements or quotes — always confirm against your actual furniture dimensions and local supplier pricing.

Frequently Asked Questions
A 6-seat dining set typically needs roughly a 10 x 10 ft (about 100 sq ft) footprint once you account for chairs pulled out and room to walk around the table. Larger tables or built-in benches need more — always measure your actual table and add at least 3 feet of clearance on every side.
36 inches (about 91 cm) is a comfortable standard for one person to walk through easily, and it’s the same clearance commonly used for indoor hallways. If two people need to pass side by side, or you’re planning for a wheelchair or stroller, aim closer to 44–48 inches.
Yes, generally — dark-colored composite decking tends to absorb more heat than natural wood or light-colored stone, and can get noticeably hot to bare feet in direct summer sun. Lighter composite tones and added shade both help reduce this significantly.
Poured concrete is typically the most budget-friendly option per square foot for a standard patio, followed by basic concrete pavers. Natural stone and composite decking tend to sit at the higher end, though exact pricing varies a lot by region and supplier.
Yes — planning only for the exact furniture footprint tends to feel cramped once chairs are pushed back and people are walking through. Adding a circulation allowance around each zone, like this calculator does automatically, gives a much more realistic and comfortable final size.
