Garden screens cover insect netting, shade mesh, and windbreak fabric. Mesh size and shade rating affect airflow, light, and pest control. UV-stabilized products last longer outdoors and resist tearing. Changes in thickness and roll width also change how many seams and overlaps you should plan for.
Measure the outside path the material will follow, not just the opening. Hoop tunnels and cages need extra length for curvature plus edge anchoring. If you use clips, battens, or channels, include that routing distance. Enter measurements in any supported unit, and the calculator standardizes results in square meters.
Overlap covers stitching, taping, hems, and tie-down margins. Flat panels often work with 5–8% overlap, while curved frames and multi-panel joins may need 8–15%. Waste accounts for trimming and miscuts. Raise waste when cutting circles or triangles from rectangular rolls.
Roll area equals roll width multiplied by roll length. The calculator divides your adjusted buy area by roll area and rounds up to whole rolls. It also reports linear length needed, which helps when suppliers cut by the meter. Cost can be estimated per roll or per square meter.
Perimeter and fastener spacing influence clips, staples, or ties. Tighter spacing improves wind resistance but increases hardware. Multiple layers multiply area directly and can change ventilation, so plan access openings early. Use leftover material for repair patches and door flaps.
1) What overlap percentage should I start with?
Start with 5–8% for flat panels. Use 8–15% for curved hoops, stitched seams, or heavy tie-downs. Increase overlap if you expect frequent removal and re-clipping.
2) How do I choose a waste percentage?
Use 8–10% for straight cuts and simple shapes. Use 10–20% for circles, triangles, or many cutouts. If you are matching patterns or reinforcing edges, add extra waste.
3) Why are results shown in square meters?
Square meters keep comparisons consistent across units. You can enter feet, inches, or centimeters, and the calculator converts to meters internally so area, roll sizing, and costs remain aligned.
4) What does “linear length needed” mean?
It is the length of material required from a roll at your chosen roll width. It helps when suppliers cut from a bulk roll and charge per meter rather than selling full rolls.
5) When should I use multiple layers?
Use layers for stronger windbreaks, better pest exclusion, or combined shade and insect control. Each layer multiplies the base area, so confirm your frame can handle added heat and reduced airflow.
6) How accurate is the fastener estimate?
It is a spacing-based perimeter estimate. Real installations may need extra fasteners at corners, doors, and high-wind edges. Treat it as a purchasing baseline, then add a small buffer.
7) Why do I still get leftover area after rounding rolls?
Rolls are counted as whole units, so the calculator rounds up to ensure coverage. Leftover area can be useful for repairs, patches, or future add-ons like vents and access flaps.
