Definition
A gripper calculator totals sharp or smooth gripper needed around a carpeted room.
Explanation
Gripper is sold in strips (often 1.5m). Deduct door openings. Use tackless strip on stairs with a stair-specific calculator.
Worked example
A 4m × 5.2m room has 18.4m perimeter. Minus two 0.9m doorways leaves 16.6m of gripper.
Summary
Order gripper in full strips and keep spare for repairs.

Gripper placement around the room
Perimeter maths
Gripper runs around the room except at door openings. For a 4m × 5.2m rectangle, perimeter is 18.4m; subtract each doorway width (typically 0.76–0.9m).
Order in standard strip lengths and keep offcuts for small repairs or cupboard floors.
Sharp vs smooth
Sharp gripper holds woven and tufted carpet securely. Smooth or dual-purpose strip suits loop piles and areas where delicate fibres sit against the pin line.
Frequently asked questions
- Smooth or sharp gripper?
- Sharp for most woven carpets at walls; smooth for delicate or loop piles near thresholds.
