Carpet Restretching Area Calculator
Calculate the total carpet area requiring restretching across multiple rooms. Enter each room's dimensions to get the total square footage and estimated restretching cost.
$
Typical range: $0.25–$0.75 per sq ft
Extra area buffer for edges and overlaps (typically 5–10%)
Formula
Room Area (sq ft) = Length × Width
Total Raw Area = Σ (Room Areai) for all rooms
Adjusted Area = Total Raw Area × (1 + Waste Factor / 100)
Estimated Cost = Adjusted Area × Cost Rate per sq ft
Unit conversions applied before calculation:
- Inches → Feet: divide by 12
- Meters → Feet: multiply by 3.28084
- Yards → Feet: multiply by 3
Assumptions & References
- Restretching cost typically ranges from $0.25 to $0.75 per sq ft depending on region and carpet condition.
- A waste/overlap factor of 5–10% is recommended to account for edges, tack strips, and irregular room shapes.
- Rooms are assumed to be rectangular; for irregular shapes, break them into rectangular sections.
- Carpet restretching is generally recommended every 5–10 years or when visible ripples/buckles appear.
- Cost estimates are for labor only and do not include furniture moving, repairs, or replacement materials.
