Standard, Sleek, vs. Slim Cans: Specifications & Lid Compatibility
Can body geometry and easy-open end engineering across Standard, Sleek, and Slim profiles and 200, 202, and 206 neck finishes.
Quick Answer: Standard (~66mm) and Sleek (~57.4 mm) cans share a Size 202 (52.5mm) neck, so co-packers switch runs with minimal seamer changes; Slim (~53mm) cans require a narrower Size 200 (50.0mm) neck. Size 206 (~57mm) ends serve large-format wide-neck cans with higher pressure resistance.

Pick the wrong can profile and your co-packer bills you for a full seamer retool. Pick the right one and you can run Standard, Sleek, and sometimes Slim on the same line with only change parts. This guide compares the three profiles we produce most often—Standard (~66mm), Sleek (~57.4mm), and Slim (~53mm)—and the 200/202/206 neck finishes that match them.
We only make aluminum cans and easy-open ends, so every number below comes from our own drawing set and shop-floor experience. Below, we break down geometric profiles, neck finish sizing, and end compatibility.
1. Body Diameters and Neck Finishes
Standard and Sleek cans both use a Size 202 neck (52.5mm curl diameter), so a line set up for one can usually run the other after a changeover. Slim cans use a Size 200 neck (50.0mm), which needs its own seamer chucks and starwheels.
This is why a co-packer running 355ml Standard beer cans can add a 330ml Sleek RTD with minimal tooling cost, but adding a 250ml Slim mixer means buying Size 200 change parts. The body diameter does not determine the end size—the neck does.
2. When to Choose Size 202 vs Size 206 Lids
Size 202 ends are the default for Standard and Sleek cans. They are cheaper per thousand and work with both B64 and CDL profiles. Size 206 ends are reserved for wide-neck large-format cans such as 24oz/709ml; the larger opening handles higher carbonation pressure and pours faster.
Most of our export orders for 330ml, 355ml, and 500ml run Size 202 CDL ends. The CDL profile cuts metal gauge by roughly 10% versus legacy B64 while still passing our 95–102 PSI buckle test.

| Can Architecture Profile | Nominal Body Diameter | Available Liquid Capacities | Matching Lid Size Finish | Standard Lid Compatibility |
|---|---|---|---|---|
| Standard Profile | ~66.1 mm (211 Body) | 330ml, 355ml (12oz), 473ml (16oz), 500ml | Size 202 (52.5 mm) / Size 206 | 202 CDL SOT, 202 B64, 206 SOT |
| Sleek Profile | ~57.4 mm (204 Body) | 250ml, 330ml, 355ml (12oz) | Size 202 (52.5 mm) | 202 CDL SOT, 202 RPT, Full Aperture |
| Slim Profile | ~53.3 mm (202 Body) | 150ml, 180ml, 200ml, 250ml (8.4oz) | Size 200 (50.0 mm) | 200 CDL SOT, 200 RPT Matrix |
4. Internal Linings by Destination Market
We match the liner to the food-contact law of the destination country. Epoxy-Phenolic is the cost-optimized choice for markets like Russia and Ghana where it is still permitted. BPA-NI is required for North America, the EU, and the UK.
High-acid or high-salt beverages put extra stress on the coating around the scoreline and tab rivet. We run automated copper-sulfate porosity tests on every lot and can supply third-party food-contact migration reports and ISO 9001 / FSSC 22000 certificates on request.
5. Contract Pricing and End Customization
We quote long-term contracts on a "metal price + conversion fee" basis. The aluminum portion moves with the raw aluminum benchmark, while our conversion margin stays fixed. That gives you a transparent forecast and the option to switch from B64 to lighter CDL ends when metal prices rise, without changing can neck specs.
On the value-added side, we offer colored lids and tabs, laser-etched tab logos, and under-tab QR codes. The QR code sits under the SOT lever and only shows after the can is opened. We have used this for loyalty programs, anti-counterfeit batch tracking, and market-specific landing pages.
Key Takeaways
- Standard and Sleek cans share a Size 202 neck; Slim cans need Size 200.
- Size 206 ends are for wide-neck large-format cans, not standard profiles.
- CDL ends cut metal use ~10% versus B64 while holding the same pressure rating.
- Epoxy-Phenolic works for price-driven markets; BPA-NI for EU/UK/North America.
- benchmark-indexed contracts and end customization are available on bulk orders.

Request a Can Profile ReviewFrequently Asked Questions
What are the key dimensional differences between Standard, Sleek, and Slim aluminum cans?
Standard Cans feature a ~66mm body diameter paired with a Size 202 neck. Sleek Cans feature a ~57.4 mm body diameter paired with a Size 202 neck. Slim Cans feature a ~53mm body diameter paired with a narrower Size 200 neck.
What is the primary technical difference between 202 and 206 easy-open ends?
Size 202 ends (~52.5mm diameter) are the global cost-effective standard for standard and sleek cans. Size 206 ends (~57mm diameter) provide a wider neck opening for large-format containers, offering higher gas pressure resistance and enhanced drinking pour velocity.
Why do Sleek cans share tooling with Standard cans?
Because Sleek cans use the same Size 202 neck finish as Standard cans, co-packers can switch between craft beer standard cans and RTD cocktail sleek cans with minimal seamer chuck adjustments. Slim cans need dedicated Size 200 chucks.
How do internal linings satisfy regional food-contact laws?
We match the liner formulation to the destination market—cost-effective Epoxy-Phenolic for high-volume markets like Russia and Ghana, and certified BPA-NI lacquers for North America and the EU.
