Wire Mesh Tools
Instant, transparent calculators for spec'ing and quoting wire mesh — built for fast specification checks, free to use.
Spec Converter
Convert mesh count ↔ opening size (inch / mm / micron) ↔ open area % ↔ pitch.
Weight Calculator
Estimate weight per m² and roll weight from mesh, wire diameter and material.
Mesh Selector
Answer three questions and get a recommended mesh type, material, aperture and wire gauge for your application.
Free wire mesh tools — built to be transparent
Wire mesh is one of the most confusingly specified products in industry. The same screen can be described by mesh count, aperture (opening), micron rating, wire gauge, open area percentage or weight per square metre — and a value that looks correct in one unit can be badly wrong in another. Most supplier sites either bury this maths or hide it behind a sales enquiry, so you cannot check the numbers for yourself.
This is a free set of transparent tools that does the wire mesh maths in the open. Every formula is shown, every unit is calculated at once, and there is no sign-up, login or paywall. You can cross-check each result by hand if you want to.
Three tools cover the decisions that matter: the Spec Converter translates between mesh, inch, millimetre and micron; the Weight Calculator estimates weight per square metre and per roll across common materials; and the Mesh Selector recommends a mesh type, material and aperture for your application. All three are built for real specification and sourcing decisions, not for show.
Which tool should I use?
Pick the tool that matches the question you are actually trying to answer. Each one is focused on a single job, and you can move between them as your spec firms up.
| Your question | Use this tool | What you get |
|---|---|---|
| "What opening is 40 mesh?" / convert mesh ↔ micron | Spec Converter | Opening in inch, mm and micron, open area % and pitch |
| "How much will this mesh weigh / cost to ship?" | Weight Calculator | Weight per m² and per roll across six materials |
| "Which mesh do I actually need for my job?" | Mesh Selector | Recommended mesh type, material, aperture and gauge |
Who these tools are for — industries and roles
Wire mesh is specified across dozens of sectors, and the same spec sheet often passes through several pairs of hands before an order is placed. These tools are built for anyone who needs to get the numbers right: filtration and separation, mining and aggregates, construction, agriculture and livestock, food and beverage, chemical processing, water treatment, architecture and the oil and gas industry all rely on mesh defined by aperture, gauge and open area. On the people side, procurement and sourcing teams use them to sanity-check supplier quotes, design and process engineers to size apertures, contractors and installers to confirm what was ordered, importers and distributors to compare offers, estimators to work out roll weights and shipping, and QC staff to verify incoming goods against the spec.
Why these tools are different
What sets these tools apart from a typical supplier calculator is transparency, not marketing. Every result is produced by a formula you can see and re-check, using stated inputs and visible equations. The upgraded calculator pages now link the relevant unit definition and woven-cloth standards while spelling out where nominal geometry stops. WireMeshQA and FenceAndMesh are operated by the same team. The calculation methods stay visible here, while product and quotation enquiries are handled separately by FenceAndMesh. We also state the limits of each result plainly, so you know when a value is a clean conversion and when it is an estimate.
- No black box: every formula and conversion is shown, so any result can be verified by hand.
- Industry-standard conventions: the main calculators now show their input definitions, equations, source notes and exclusions.
- Ownership disclosed: the shared operation with FenceAndMesh is stated, while the formulas and limits remain visible for checking.
- Honest about limits: weight and open-area figures are clearly flagged as estimates that depend on exact wire diameter and weave.
- No sign-up: free to use, instantly, with no login, email capture or paywall.
Frequently asked questions
Are these wire mesh tools really free?
Yes. The Spec Converter, Weight Calculator and Mesh Selector are completely free to use, with no trial period, credits or premium tier. There is nothing to pay and nothing to unlock. The tools exist to make specification easier and are separated from product and quotation enquiries.
Do I need to sign up or share my email?
No. You can use every tool instantly without an account, login, email address or any personal details. Nothing you type into a calculator is required to be saved or submitted, so you can run a conversion, check a weight or compare options and simply close the page when you are done.
How accurate are the results?
The inch-to-millimetre unit conversion is exact; aperture, weight and open-area outputs are nominal calculations based on the entered mesh count, wire diameter and density. Those figures are estimates, because they depend on the precise wire diameter and weave of the finished product. Treat them as a reliable working figure for planning, and confirm the exact value against a final mill specification before ordering.
What should I do after building a mesh specification?
Save the mesh type, opening, wire diameter, material, finish, format and quantity as a written brief. Send the same brief to qualified suppliers, compare like-for-like responses and independently verify the final mill specification, tolerances and commercial terms.
Need a clearer starting specification?
Use the selector first, then check units and estimated weight with the supporting tools.
