Wire Mesh Tools
Instant, transparent calculators for spec'ing and quoting wire mesh — built by an independent answer engine, 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, independent set of 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 industry-standard conventions — mesh count is wires per inch, gauges follow the Standard Wire Gauge (SWG) system, micron ratings align with common ISO and ASTM practice, and apertures follow standard sizes. Because the site is independent and not tied to selling one particular product, there is no incentive to nudge you toward a specific mesh. 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: wires-per-inch mesh counts, SWG gauges, ISO/ASTM-aligned micron ratings and standard apertures.
- Neutral and independent: not tied to selling a single product, so the maths is the only agenda.
- 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 site is an independent wire mesh reference, and the tools exist to make specification easier, not to sell you software.
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?
Conversions between mesh, inch, millimetre and micron are exact, based on standard definitions you can re-check by hand. Weight and open-area 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.
Can you help me actually buy the mesh once I've spec'd it?
Yes. Once your specification is confirmed with these tools or our <a href="/guides/buying-guide/">buying guide</a>, you can send it through our <a href="/contact/">contact page</a> for a free, factory-direct quote. We do not list prices or push a particular brand — we simply pass a confirmed spec to suitable supply so you can compare offers on your terms.
