SettingsSettings for this calculationUS
The total linear length of building perimeter or scaffold to be enclosed with netting.
Measure the full run of perimeter or scaffold edge that needs netting coverage, including all sides being enclosed.
The vertical height of netting coverage needed at each point along the perimeter.
This is the vertical drop of the net panel itself (e.g. one scaffold lift height, or the full building elevation being screened), not the height above ground.
Total netting area needed
5,070 sq ft
This is a material-quantity takeoff only. If this netting is intended as fall-arrest protection under OSHA 29 CFR 1926.502(c) (not just debris containment), the specific net product must have certified drop-test/impact-energy data and be installed per its manufacturer's requirements and a qualified person's fall protection plan — this calculator does not verify that.

How this was calculated
Formula source(s)
- Net area = Perimeter Length × Net Height, a straightforward material-quantity takeoff for perimeter debris/catch netting or safety netting systems used on scaffolds and building exteriors during construction. This is a quantity takeoff only — it does not address the specific mesh size, drop-test/impact-energy rating, or attachment requirements for netting used as actual fall-arrest protection under OSHA 29 CFR 1926.502(c), which requires certified test data specific to the netting product.
Inputs used
- Perimeter/Scaffold Length to Net
- 260 ft
- Net Height (Vertical Coverage)
- 19.5 ft
Confidence note: This is a material-quantity takeoff only. If this netting is intended as fall-arrest protection under OSHA 29 CFR 1926.502(c) (not just debris containment), the specific net product must have certified drop-test/impact-energy data and be installed per its manufacturer's requirements and a qualified person's fall protection plan — this calculator does not verify that.
What this calculation does not cover
- Netting a scaffold changes what the scaffold has to resist. An open frame lets wind through; debris net turns it into a partly solid surface, and the load it collects goes straight into the ties. A netted scaffold needs a denser tie pattern than the bare frame it was designed as — the tie schedule follows whether the scaffold is bare, netted or sheeted — and adding net to an existing design without revisiting the ties is a well-known way to pull a scaffold off a building.
- The fixings are the quantity that gets forgotten. Net is tied to the scaffold at every eyelet along the top edge and at intervals down the standards, and adjacent panels are laced together for the full length of each seam. What the job actually needs beyond the area is a count of ties or clips per unit length of edge and a length of lacing cord per seam — order area alone and the net turns up with nothing to hang it by.
- Any opening cut into the net has to be re-edged. Hoist openings, loading bays, window access and cuts around tie tubes are not simple deductions from the area: a cut edge in mesh runs unless it is bound or roped, so each opening adds edge rope and fixings and takes that panel outside the edge detail it was supplied with.
