| Scenario | Panel size | Qty | Overlap | Waste | Cutouts | Net area to order |
|---|---|---|---|---|---|---|
| Facade screens | 2.4 × 1.2 m | 18 | 5% | 7% | None | ≈ 59.3 m² |
| Safety enclosure | 3.0 × 1.0 m | 10 | 50 mm edges | 10% | 2 × (0.6 × 0.6 m) | ≈ 34.1 m² |
| Ventilation covers | Ø 1.2 m | 6 | 3% | 5% | 6 × Ø 0.15 m | ≈ 6.9 m² |
These examples are illustrative. Your site conditions may require higher waste or overlap.
Accurate screen takeoff starts with consistent panel geometry. This calculator converts common units, applies the chosen shape formula, and multiplies by quantity to create a clean gross area baseline. For rectangular panels, length times width is most common; circular and triangular options support duct caps, guards, and framed corners. Use custom area when drawings already provide measured coverage.
Overlap is where many orders drift. Percent overlap is useful when seams vary across elevations, while edge overlap models a fixed lap on each side. Edge overlap increases dimensions before area is computed, which better represents a uniform border allowance. Typical detailing uses small laps for fastening lines and larger laps for wind screening. Set overlap based on your fixing schedule and edge trims.
Openings reduce material, but they also increase labor. Add rectangular or circular cutouts for access hatches, vents, and conduit passes. The calculator subtracts cutout totals from gross area before waste is applied, helping you avoid underbuying. If cutouts are repeated, use quantities to speed entry. For irregular penetrations, approximate with equivalent rectangles or circles.
Waste accounts for trimming, damage, off‑cuts, and alignment. Many projects start with 5 to 12 percent, then adjust by panel size and installation complexity. When rolls are used, the tool converts net area to linear length using roll width, then estimates rolls from roll length. This supports purchasing decisions and reduces leftover stock. Add a price per square meter to estimate material cost.
Mesh specification affects performance beyond area. The optional open‑area module estimates openness using mesh count per inch and wire diameter in millimeters. It derives pitch as 25.4 divided by count, then computes opening in each direction. Higher openness improves airflow and visibility, while lower openness increases protection and screening. Use the calculated open area to compare functional coverage across materials. Validate open‑area inputs against supplier data sheets before final procurement decisions.
Use percent overlap when seam allowance varies by location or detailing. Use edge overlap when you have a fixed lap on every side. Edge overlap adjusts dimensions first, which better matches consistent border laps.
Run the calculator once per panel size, then add the net areas together. Export each result to CSV and combine totals in a spreadsheet. This approach keeps cutouts and waste aligned with each panel type.
Yes. Cutouts are subtracted from gross area before waste is applied, so the waste percentage is calculated on the remaining net area. This mirrors real ordering where trimming happens around openings.
Leave roll width and roll length blank. The calculator will still provide net area to order in square meters. Once the supplier confirms roll dimensions, re-enter them to get linear meters and roll count.
Net area includes overlap and waste factors. If overlaps add material and waste is applied, the final order quantity may exceed the original geometric area. Cutouts reduce it, but overlap and waste often dominate.
It is a geometric estimate based on mesh count per inch and wire diameter. Manufacturing tolerances and weave style can change openness slightly. Use it for comparisons, and confirm final values from supplier specifications.
Note: This tool supports planning estimates. Verify final takeoffs with shop drawings and supplier specifications.
