Event Badge Sizes Explained: 4×3 vs 4×6 vs A6

Badge size seems like a minor detail until you see a 4×6" badge on a lanyard at a cocktail reception. Here's how to choose the right size for your event. ## 4×3" (102 × 76 mm) The industry standard for conferences and seminars. This is the size you see at most corporate events. **Pros:** - Fits standard PVC holders - Not obtrusive during networking - Enough space for name, company, and QR code - Most cost-effective to print **Cons:** - Limited space for logos and sponsor branding - Small QR codes can be hard to scan from a distance **Best for:** Multi-day conferences, seminars, workshops, and most corporate events. ## 4×6" (102 × 152 mm) The large-format option. Popular at trade shows where visibility from a distance matters. **Pros:** - Highly visible across a crowded exhibition hall - Plenty of space for sponsor logos and session schedules - Large QR codes scan easily **Cons:** - Can feel oversized at seated dinners - Requires larger holders or clips - More expensive per badge **Best for:** Trade shows, expos, and events where attendees walk large distances. ## A6 (105 × 148 mm) The European standard. Slightly narrower and taller than 4×6". **Pros:** - Professional, passport-like proportions - Works with A-series paper systems - Good balance of visibility and portability **Cons:** - Less common in Asia, holders may be harder to source - Slightly more expensive than 4×3" **Best for:** International conferences, association events, and European-headquartered companies. ## Custom Sizes Some events need non-standard sizes: | Custom Size | Use Case | |---|---| | 3×4" (vertical) | Events where name visibility at chest height is priority | | 5×7" (table tent) | VIP dinner seating cards that double as badges | | Round 80 mm diameter | Festivals and casual networking events | | Wristband 25×250 mm | Events where hands-free is essential | ## Size Comparison Table | Size | Dimensions | Visibility | Cost | Best For | |---|---|---|---|---| | 4×3" | 102 × 76 mm | Medium | Low | Conferences, seminars | | 4×6" | 102 × 152 mm | High | Medium | Trade shows, expos | | A6 | 105 × 148 mm | High | Medium | International events | | Custom | Varies | Varies | High | Special requirements | ## How Size Affects Printing Not all printers handle all sizes: - **Zebra ZD621:** 4×3" and 4×6" fanfold - **Brother QL820:** 62 mm continuous (custom cut) - **Epson C4000:** Up to 4×6" inkjet - **Epson L3250:** A6 and custom sizes **Not sure which size?** [Request a quote](/quote/) and tell us your event type.
