Is there a standard badge size?
For event badges, no. There is no Brazilian standard defining credential dimensions, which is why you find different sizes at every supplier.
What does exist are card standards the market borrows from other uses. The main one is the bank card format, defined by the international standard ISO/IEC 7810 as 85.6 x 54 mm, used for employee ID badges. Paper follows the ISO 216 family, where A6 is 105 x 148 mm and A7 is 74 x 105 mm.
In practice, event credentials in Brazil cluster into three bands. It is worth understanding what each one solves before choosing.
The most used formats
| Format | Dimensions | What fits | Best for |
|---|---|---|---|
| Standard card | 86 x 54 mm | Small name and photo | Employee badge, permanent access |
| Medium credential | 9 x 12 cm | Name, company, QR code | One-day event, internal audience |
| Large credential | 10 x 14 cm | Legible name, tier, logos | Conference, trade show, sponsored event |
EcoCrachá uses 14 cm tall by 10 cm wide, within the large band, because the format has to accommodate two things at once: the attendee's information during the event and the sponsor's brand space, which is what makes zero cost possible for the organiser.
Choose by what has to fit
Before deciding the size, list what gets printed. It is usually more than people remember:
- The attendee's name, which is the most important item
- Company or institution
- Access tier: attendee, speaker, press or staff
- QR code or barcode for accreditation
- The event logo
- Sponsor logos
- Numbering or internal identification
Add that up and test it on a piece of paper cut to the size you are considering. A 9 x 12 cm format with seven elements becomes a pile-up. That is the moment to find out, not after a thousand units have been printed.
Reading distance decides the rest
Here is the criterion almost nobody applies and that makes the biggest difference to the event experience.
A credential exists for two jobs: access control and networking. Access control is handled by the QR code, which the scanner is brought close to. Networking is different: a person has to read the name of whoever is in front of them without leaning in awkwardly, which means reading from about a metre and a half.
A name in a small size, 12 or 14 points, forces the attendee to lean forward and squint. In our experience the name works well from 20 to 24 points in bold, and that already sets a minimum width for the badge. If the chosen format does not allow that type size, the format is wrong, not the font.
One inversion that helps: set the first name large and the surname smaller, on separate lines. At events, people address each other by first name.
Portrait or landscape
Portrait, taller than it is wide, is the most common at conferences and trade shows. It follows the natural fall of the lanyard and keeps the content aligned with the body.
Landscape, wider than it is tall, gives more width for a long name and for a horizontal logo, which is the shape of most brands. The problem is that it spins more on the chest and often ends up sideways.
If you use landscape, use two holes instead of one. That is the difference between the credential sitting straight and sitting crooked all day.
Lanyard length
The lanyard changes the height at which the credential sits on the body, and that matters for reading.
EcoCrachá comes with a 45 cm lanyard, measured flat, which forms a loop of about 90 cm and leaves the credential at chest height. A longer lanyard sends the piece down to the waist, where nobody reads it. A shorter one is tight round the neck.
If your event has official photography or a broadcast, a lanyard at chest height is also what keeps the brand visible in the image.
Safety margin in the file
A technical detail that generates rework: reserve a clear area at the top of the credential, where the lanyard hole goes. If the logo or the name sits flush with the hole, the lanyard's tension point runs over the information and the cut may go through the text.
Leave slack at the edges too. Industrial cutting has a tolerance, and content pressed against the margin comes out misaligned on part of the run. Ask the supplier for the template before finalising the artwork, with the cut marks and the safety area already indicated.
Common sizing mistakes
Choosing by the price list. A smaller format is cheaper per unit and then does not fit the sponsor logo you already sold in the package. At that point the saving became a commercial problem.
Copying last year's size without reviewing it. If this year you have more sponsors or a new access tier, the old format may no longer work.
Ignoring duration. A three-day event means a credential handled, stuffed into a backpack and worn again. A large format in fragile material creases by day two. That is where the size decision meets the material decision, which we cover in how to choose the credential for your event.
Leaving the QR code too small. A code squeezed into a corner jams scanning and the queue stops. Reserve real space for it.
Quick reference
If you want the short answer:
- One-day corporate event, small audience: 9 x 12 cm does the job
- Conference, trade show, sponsored event: 10 x 14 cm is the safe format. See conference badges and trade show badges
- Employee badge for permanent use: 86 x 54 mm, card format
- Lanyard: 45 cm flat, which is a loop of about 90 cm
Frequently asked questions
What is the standard badge size for events?
There is no official standard for event credentials. The Brazilian market works with three bands: the standard card at 86 x 54 mm, the medium credential at 9 x 12 cm and the large credential at 10 x 14 cm. For conferences and trade shows, the large format is the most used because it accommodates a legible name, the access tier and a sponsor logo.
What size is the EcoCrachá?
EcoCrachá measures 14 cm tall by 10 cm wide and comes with a 45 cm lanyard. It is a large format, which allows a name at a size legible from a distance plus the sponsor's brand space.
What is the best badge size for a conference?
The large format, around 10 x 14 cm. Conferences usually run several days, have several access tiers and more than one sponsor, and all of those elements have to fit without competing with the attendee's name.
What type size should I use for the name on a badge?
Think in terms of reading distance rather than the number on its own. The name has to be read from about a metre and a half, for networking, and in practice that usually calls for 20 to 24 points in bold. If the chosen format does not allow that size, it is the format that is too small.
What is the ideal lanyard length?
Around 45 cm measured flat, which forms a loop of roughly 90 cm and leaves the credential at chest height. A longer lanyard drops the piece to the waist, where the name does not get read.
Portrait or landscape badge, which is better?
Portrait is the most common at events because it follows the fall of the lanyard and sits straight on the body. Landscape offers more width for a long name and a horizontal logo, but it spins easily, so use two holes instead of one to stabilise it.
In closing
Badge size looks like an operational detail and it is an experience decision. The right format is the one that keeps the name legible at a metre and a half, accommodates what you sold in sponsorship, and survives the length of the event.
The EcoCrachá works at 14 x 10 cm in recycled PET canvas, and after the event the credential turns into a wallet instead of becoming waste. Request a quote with the number of attendees at your event.
