Metal Eyelet Sizes: Complete Size Chart from 4mm to 40mm
Complete metal eyelet sizes chart from 4mm to 40mm. Find the right grommet size for shoes, bags, curtains, tarps, and garments with our detailed guide.
Choosing the correct eyelet sizes is critical for both function and appearance. An eyelet that is too small will restrict lacing or airflow; one too large will look sloppy and may pull through the fabric. This complete guide covers every standard metal eyelet size from 4mm to 40mm, with detailed specifications and application recommendations.

1. Understanding Eyelet Measurements
When discussing eyelet sizes, three measurements matter:
- Inner Diameter (ID) — the hole opening through which lace, cord, or rope passes. This is the most important measurement.
- Outer Diameter (OD) — the total diameter including the flange. Determines the visible footprint on your material.
- Barrel Length — the height of the tubular section that passes through the fabric. Must match your material thickness.
2. Complete Eyelet Size Chart
Here is the complete eyelet sizes reference chart with all standard dimensions:
| Size Code | Inner Diameter | Outer Diameter | Common Use |
|---|---|---|---|
| #0 | 4mm | 8mm | Lingerie, delicate fabrics |
| #1 | 5mm | 10mm | Shoes, light garments |
| #2 | 6mm | 12mm | Shoes, bags, belts |
| #3 | 8mm | 14mm | Bags, curtains, apparel |
| #4 | 10mm | 17mm | Canvas bags, banners |
| #5 | 12mm | 20mm | Tarps, heavy canvas |
| #6 | 14mm | 23mm | Industrial tarps, marine |
| #7 | 17mm | 27mm | Awnings, large banners |
| #8 | 20mm | 30mm | Shower curtains, signage |
| #10 | 25mm | 35mm | Truck covers, rope guides |
| #12 | 30mm | 40mm | Heavy industrial, drainage |
| #15 | 40mm | 52mm | Marine, heavy-duty industrial |
3. Size Recommendations by Application
- Shoe eyelets: 4mm–6mm ID
- Belt eyelets: 6mm–8mm ID
- Corset eyelets: 5mm ID
- Hoodie drawstrings: 8mm ID
- Tarpaulins: 12mm–14mm ID
- Marine canvas: 14mm–20mm ID
- Banners and signage: 10mm–12mm ID
- Truck covers: 20mm–25mm ID
4. Eyelet vs. Grommet Sizing
The terms "eyelet" and "grommet" are often used interchangeably, but there is a practical difference. Eyelets are typically smaller (under 12mm ID) and consist of a single piece that rolls over on itself. Grommets are larger, two-piece assemblies with a separate washer ring for reinforcement. The same eyelet sizes system applies to both, but grommets offer more strength at larger diameters.
5. How to Measure for the Right Eyelet
To select the correct eyelet sizes, follow these steps:
- Measure the cord or lace — the inner diameter should be at least 1mm larger than the cord that passes through it
- Measure the material thickness — the barrel length must accommodate your fabric layers plus any reinforcement tape
- Consider the aesthetic — outer diameter determines visual impact; larger flanges look more prominent
- Account for the hole punch — the hole you cut should match the barrel diameter exactly, not the inner or outer diameter
6. Ordering the Correct Size
When placing your order, always specify: inner diameter, material (brass, stainless steel, iron), finish (nickel, antique brass, matte black), and barrel length. Providing all four parameters eliminates errors and ensures you receive exactly the right eyelet for your project.
