Wire Mesh Standard Size Chart: Complete Guide for Global Importers & Contractors
Choosing the correct wire mesh size is one of the most important steps in any construction, fencing, agriculture, or industrial application. A wire mesh standard size chart helps engineers, buyers, and contractors select the right opening size, wire thickness, and mesh dimensions to ensure performance, safety, and cost efficiency.
However, global buyers often face three challenges:
- Mesh standards differ by region (ASTM, BS, ISO, CN standards, etc.)
- Suppliers use different mesh numbering systems
- Wrong mesh selection can lead to rework, weak protection, or unnecessary cost
To solve this, we prepared a comprehensive and export-focused wire mesh size chart, tailored for B2B buyers and project contractors.
As a professional factory, we do not just provide data — we help you make confident purchasing decisions for long-term application reliability.
What Is a Wire Mesh Standard Size Chart?
A wire mesh standard size chart lists mesh opening sizes, wire diameter, and dimensions. It allows you to compare specifications easily when sourcing woven or welded mesh.
It typically includes:
| Parameter | Description |
|---|---|
| Mesh opening | Distance between parallel wires |
| Mesh count | Number of openings per inch (imperial standard) |
| Wire diameter | Thickness of wire |
| Material | Galvanized, PVC-coated, stainless steel, etc. |
| Standard height & length | Typical roll or panel sizes |
| Weight (optional) | Useful for transport, strength, costing |
Because mesh is used in many environments — fencing, farming, building, filtration, and reinforcement — there is no single global chart. Instead, buyers rely on common standard ranges.
Why Mesh Size Standards Matter
Selecting the correct size ensures:
- Proper structural strength
- Smooth installation
- Long service life in harsh environments
- Compliance with construction standards
- Best cost-performance ratio
Incorrect sizing can cause project delay and even failure. Therefore, a clear wire mesh size chart helps reduce risk.
Global Mesh Size Systems Explained
Different countries use different systems. Below are the most common:
| Region | Standard Format | Notes |
|---|---|---|
| USA | Mesh number per inch | ASTM |
| Europe | mm opening & mm wire | EN |
| China | mm opening (GB Standard) | CN GB/T |
| Middle East | mm opening & gauge | Mixed standards |
| Africa & Latin America | mm opening & gauge | Imported specs common |
To bridge global differences, we offer dual-unit charts (inch + mm).
Standard Welded Wire Mesh Size Chart (Galvanized / PVC-Coated)
| Opening Size | Mesh Count | Wire Diameter | Standard Width | Standard Length |

Standard Expanded Metal Mesh Chart
| Opening Type | Opening Size | Strand Thickness | Sheet Size |
|---|---|---|---|
| Diamond | 10×25mm–50×100mm | 1–5mm | 1×2m / 1.2×2.4m |
| Heavy Expanded | 50×100mm & above | 3–8mm | Custom also |
Industrial platforms, walkways, security partitions, machine guarding.
Understanding Mesh Count vs Opening Size
- Higher mesh number = smaller openings
- Lower mesh number = larger openings
Example:
| Mesh No. | Opening |
|---|---|
| 4 mesh | ~6.35mm |
| 1 mesh | ~25mm |
Therefore, always confirm whether the supplier uses:
- Mesh number (per inch)
- Exact mm opening
This ensures accurate procurement.
Wire Gauge Conversion Table (AWG vs mm)
| AWG | mm |
|---|---|
| 20 | 0.81 |
| 18 | 1.02 |
| 16 | 1.29 |
| 14 | 2.03 |
| 12 | 2.64 |
| 10 | 3.25 |

Factory Perspective: How to Choose the Right Mesh?
As a manufacturer, we always guide buyers through questions:
| Question | Purpose |
|---|---|
| Where will you use the mesh? | Outdoor? Indoor? Marine? |
| What loading strength do you need? | Determines wire thickness |
| What is the exposure environment? | Rust resistance level |
| Do you need rolls or panels? | Installation method |
| What lifetime do you expect? | Material choice |
This ensures you receive the most suitable product — not just the cheapest one.
