Mesh rolls needed

3 rolls

High confidence

At the values currently entered, the mesh rolls needed works out to 3. Figures are shown for United States, where IRC 2024 is the governing residential reference; switch the market above if you are building elsewhere.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

Why does mesh area need an overlap allowance before converting to rolls?
Adjoining mesh strips must overlap at every seam so the base coat bonds the reinforcement continuously across the wall — this overlap adds material beyond the raw wall area before the total is divided into rolls.
Why is the roll count always rounded up?
You cannot buy a fraction of a roll, so the required area is always rounded up (ceiling) to the next whole roll, the same convention used for other rolled or sheet materials.
Does the roll coverage area vary by manufacturer?
Yes — roll width and length differ by mesh product and manufacturer, so enter your specific roll's coverage area rather than assuming the ~46.5 m² (500 ft²) example value.
