Badge Sizes, Fonts, and Colours. Design Tips that Improve Readability

At most events, your badge is doing a lot more work than you might think. It’s your introduction, your affiliation, your pass, and sometimes even your map. But none of that matters if it can’t be read at a glance.

That’s why readability matters so much on event badges. People don’t stop to study them. In real-world settings — such as hallways, queues, and coffee breaks — badges need to deliver information instantly and clearly. That’s especially true for networking: if someone can’t read your name or company from a metre away, that’s a missed opportunity. And if dozens of badges look different, use tiny fonts, or rely on light pastel text on white backgrounds, things go downhill fast, which is why we have concise guidelines on what should an event badge include.

Design of event badges. Sizes, fonts, colours

In this guide, we’ll look at how to get your event badge size, font, and colour choices right, without sacrificing your brand’s visual style. You’ll also find tips for dealing with hard-to-read brand guidelines and how to keep everything polished.

Big enough to be useful. Let’s talk size

The right event badge size depends on your use case, but for conferences, expos, and networking-heavy events, a larger size is generally more suitable. Consider: space for large text, a logo, and possibly a scannable QR code.

• – Recommended badge size: 100×140 mm (portrait) or 110×85 mm (landscape);
• – Avoid credit-card-sized badges unless they’re only for access control;
• – Leave 5–10 mm of padding around the edge to prevent anything from being cropped or hidden.

If you’re printing double-sided badges (Why should you do that? Because badges flip!), make sure both sides are equally readable.

A tough font choice. Clarity > personality

You don’t have to ditch your brand’s font entirely, but it can’t outshine the practical aspects. We’ve written more about this topic in our article: Top 7 Badge Printing Mistakes and How to Avoid Them. Check it out.

Make sure to:

Use sans-serif fonts for readability (anything like Montserrat, Roboto, or Helvetica will work just fine);

• – Ensure there’s at least a 3-point size difference between name, company, and other info;
• – Avoid all-uppercase text for names—it’s harder to read quickly;
• – Aim for font sizes of 24–36 pt for names, and no smaller than 14–16 pt for secondary info.

If your brand font is decorative, narrow, or low-contrast, keep it for the logo and headlines rather than for people’s names.

Colour choices that don’t sacrifice clarity

Usually, colour is part of your brand identity, but when it comes to event badge colour, it also plays a significant role in whether people can read what’s printed.

• – Use dark text on light backgrounds (black on white or navy on beige is safe);
• – Avoid low-contrast combos like yellow on white, light blue on grey, or red on orange;
• – Make sure colour-coding is visible and straightforward (e.g. a colored dot or stripe, not the entire badge);

Use your brand palette wisely (don’t overdo it just because it’s in the guidebook). And if your event branding features low-contrast pastel tones, use them as accents or borders, and anchor the core info in high-contrast text blocks.

If your brand palette isn’t readable

Sometimes the brand or event has a colour palette that just doesn’t work for print or legibility. When that happens, your job is to adapt smartly, not abandon your identity. It’s a difficult task, of course, but you can make it if you:

• – Stick to the brand’s dominant colour for borders or badges’ edges;
• – Use white or pale backgrounds for content areas;
• – Anchor text in dark overlays (e.g. white text on brand-blue background);

For digital assets, you have more flexibility. But for print, prioritise contrast.

Designing for readability is designing for everyone

Sounds relatively easy, right? Because it is.

Readable, minimalist event badges are simply professional. And, on top of that, they’re more inclusive. For attendees with vision impairments, neurodivergent individuals, or those with dyslexia, clear layouts and high-contrast designs make a significant difference. And trust us – they will see that, comparing your event to the others, and recognise that you put the energy into changing the design for them.

Our tip: In photos, too, readable badges show better, meaning your post-event wrap-ups and press materials will look more polished and intentional.

Checklist: design choices that improve badge readability

We want to finish this article with a checklist that will help you create perfect premium badges for your event.

Here’s what you have to tick off.

☐ Badge size is large enough (100×140 mm is a safe bet)

☐ Fonts are clean, sans-serif, and sized clearly (name = 24–36 pt)

☐ Colour contrast is high (dark text on light background)

☐ Layout leaves space between elements (no visual clutter)

☐ Branding elements don’t overwhelm the key info

☐ Colour-coding is simple and easy to interpret

☐ Information hierarchy is clear (name > company > role > event name)

☐ Tested print proof for legibility before full run
