  • Measure the delivery route separately.
  • Include projecting arms and removable legs.
Method

What this result assumes

A sofa against one wall is evaluated with open floor in front.

15 cm at each side and 90 cm in front are conservative planning targets, not universal rules.

Limitations

What it cannot confirm

This is a planning estimate, not a building-code, safety, installation, or delivery guarantee.

Confirm product-specific requirements with the manufacturer, installer, retailer, or qualified trade.
