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.
