Lanyard Sizes: Choosing the Right Measurements for Your Team with Zero Faff

Lanyards are inherently visual tools; they double as branding aids, wayfaring supplements, a physical employee ID or visitor management system, the list goes on… Yet that doesn’t necessarily mean that aesthetic is the be all and end all. If I use our customer trends as a barometer, in 2026, businesses are prioritising the practical. To work well in the real world, organisations must first have a solid grasp on the right lanyard sizes for their needs.

After all, one supplier’s ‘standard’ is another supplier’s ‘small’. And you can’t have your staff’s lanyards bouncing off belts or chafing around their necks when they have an important job to do.

To that aim, this guide will outline the typical lanyard widths, lengths and card attachment sizes for the most popular use cases. And, while I’m at it, I’ll also show you how at Only Lanyards we walk clients through the decision-making process.

TL;DR: British Lanyard Sizes at a Glance

The short version of this guide is that…

• Standard lanyard sizes are 90cm long, with a drop length of 45cm and a 1.5-2cm width.
• Event lanyard sizes usually sit at the typical 90cm long, but with broader widths of at least 2cm.
• Children’s lanyards are 80-85cm long and 1-1.5cm wide, fitted with safety breakaways as standard.
• Custom sizes and adjustable-length lanyards are available for those who need flexibility
  
  

Why Lanyard Dimensions are Anything But Trivial

As I mentioned up top, lanyard priorities are increasingly geared towards the functional. Nowadays, organisations are designing this essential hardware to be explicitly moulded to the setting rather than as a simple placeholder for a logo. As such, the first questions buyers typically ask fall along the lines of: “Where will our lanyards be worn, and what do we want them to achieve?”

The answers will, without exception, inform your sizing. Not least because your size estimates have an outsized impact on…

• Safety: More than a mere hassle, oversized lanyards present a snag risk, whilst undersized ones are a choking hazard. To keep the wearer safe, ensure the fit is slack but not swinging; ideally, sat at your midriff where it won’t restrict your movement.
• Comfort: The cold touch of a key fob or whistle on your neck all day long is the recipe for a sensory nightmare, as is a tight cord that bites down on your skin. As such, size is a major comfort-factor you can’t put off – no ifs or buts.
• Accessibility: As powerhouse universal design advocate and speaker, Molly Burke, attests “Accessibility is not niche. It is not special. It is good design that benefits all of us” – and this goes for all products,lanyards included. So, make sure your sizing options suit all your users, especially if they were designed with disabled folk in mind á la the sunflower lanyard.
• Convenience: Correctly sized lanyards eliminate those moments of frustration where you have to knot up the material to stop it from hanging too low or double loop it around a belt to avoid the discomfort.
• Wastage: Lanyards that are unnecessarily long, aren’t simply a workplace hazard; they’re just as much a waste of material, even if you’ve opted for a lower-impact material such as recycled rPET or bamboo.
• Professionalism: Lastly, when you’re a public entity, such as a charity, university, school, business or event organiser, optics matter. And, trust me, you don’t want stakeholders to be squinting at your workforce, wondering why something looks off with the uniform. Project professionalism like your life depends on it!

Let’s Get on the Same Page: Which Lengths are we Talking About?

You’re dying to find out which dimensions constitute standard size. First, though, a micro-myth buster. When we lanyard suppliers talk about length we mean one of two things:

1. Total length, as in the end-to-end size of the fabric if you laid it out flat, from tail to tip.
2. Drop length, or how far the lanyard hangs from your neck to the clip at the bottom.

Then there’s width, which is self-explanatory: basically, how wide the strap is. Of course, there’s the extra millimetres of anything you decide to carry on your lanyard to account for – I’m thinking water bottles, ID cards, keys, lip balm and other small essentials – but these are generally regarded as separate to the main length.

So, What’s the Standard Lanyard Size?

In the UK, we have standardisation on our side, because, on the whole, most reputable vendors will follow a set of uniform sizes.

As such, the typical lanyard – or ‘standard lanyard’ – comes in at a reliable 90cm in length, paired with a width of 1.5-2cm, depending on the intended application. The drop length, in this case, would be 45cm.

These dimensions are made for the average adult, with the expectation of everyday general use, such as in an office or school. Often, they’ll come paired with a retractable badge reel or other form of lanyard attachment to provide easy breezy access to anything you choose to carry on there, so you’ll have a few extra millimetres if you need them.

And, When Should Organisations Consider Something a Little Less Typical?

Since we live in a non-uniform world, many businesses will necessarily need bespoke lanyards to suit their requirements. To cut to the chase, the bottom line is that the best design is one befitting of the setting.

Hazardous workplaces can’t afford to have staff lanyards catching on machinery; neither should they pose a hygiene risk in healthcare environments. Sounds familiar? Then you should consider factoring lanyards into your broader workwear risk assessment to pinpoint the optimal length for safety.

Truly, the notion of “one-size-fits-all” is a massive misnomer.

Real-World Use Cases to Draw Inspiration From

Still scratching your head? I don’t blame you; there are myriad uses for lanyards, and they can be used practically anywhere. This means the scope for tailoring your overall design to their application is huge.

To whittle the bulk of your pondering down, let me walk you through our general recommendations.

Hygiene-First Spaces, From Canteens to Hospitals

When food or healthcare is involved, your lanyards must be tightly controlled to prevent swinging and the unwanted dispersal of bacteria through touch. For this reason, in labs, clinics, GPs, hospital wards and care settings, we point professionals towards shorter lanyard lengths with limited extras.

We recommend:

• Shorter or adjustable length lanyards
• Thinner straps to reduce exposure to germs
• Essential, wipeable attachments only to avoid the build up of microbes
• Flat, easy-to-clean finishes you can machine wash after your shift
• Breakaway clips as a must, so you don’t get caught on beds or medical equipment
• Non-tarnishing clips for optimal longevity

Heavy Industries, Distribution or Processing Hubs

Anywhere with heavy duty machinery, tools, vehicles and fast-paced processes should take their lanyard design very seriously. Again, the onus is on employers to recognise snag risks and opt for shorter lanyards to curb any accidents.

We recommend:

• Reduced lengths to minimise entanglement
• Safety breakaways for scenarios where the lanyard may catch on surfaces
• Strong, durable clips for keys, access fobs and ID
• Robust strap materials, potentially with a tight weave

Educational Settings

Where children are involved, lanyards must fit well (read: not be grabbable by their little hands). Thus, teachers, nursery assistants, youth workers, receptionists and other school staff ought to keep them out of reach, either laid flat, snugly on the chest or attached properly to a belt. Note that wider straps may be preferable to more clearly display the institutional logo, so authorised visitors and staff can be identified in a blink.

We recommend:

• Standard lanyard lengths for university, sixth formers, college and secondary school staff, but shorter straps for those working with younger students
• Breakaway clips for any children who need to wear lanyards
• Colour coded lanyards for access control and child safeguarding purposes
• Robust clips and attachments to withstand continual, daily use

Events, Occasions & Press Opportunities

If there’s any setting that demands a decent surface area it’s at events and public occasions. Double down if press coverage is on the table. Here, broader lanyard widths and longer straps are an advantage rather than a hindrance, because it means more space to flaunt your brand.

We recommend:

• 90-100cm lanyards, with a width of 2-2.5cm, for maximum visibility
• Double-ended hardware to keep your badges front-facing 24/7
• Robust materials such as woven jacquard fabric, which incorporates the logo directly into the weave
• Or strong dye sublimated polyester, for a compromise between full colour, pigmented printing and longevity

Day-to-Day Security & Workplace Use

Just as teachers and health professionals require something anti-snag, strong, durable and easy to clean, security guards and janitors ought to enjoy the same features. On top of these requirements, though, may be the addition of a high-strength attachment to carry keys, fobs, ID and any other access control devices.

We recommend:

• A compromise between strength and size, so staff can carry what they need to without straining the material or leaving the door open to snag hazards
• Safety breaks and carabiner clips, or perhaps a J hook for ID visibility
• Colour coding across office departments and access levels

What About Attachments, Like ID Badges?

Lanyard design doesn’t stop at the strap (even if it’s the most exciting bit). Equal attention needs to be paid to the hardware you attach at the bottom for safety, streamlined use and, of course, branding.

There are swathes of fittings to wade through, but the middle-of-the-road approach which satisfies most businesses is the trigger clip x safety break combo. This ensures you can carry a range of small attachments whilst giving you the peace of mind of a quick-release escape if the strap catches on anything.

Turning our minds to ID badges now, the standard dimensions (otherwise known as “credit card size” or CR80) sit at 86mm x 54mm. Larger and smaller profiles both exist for more specialised use cases.

How We, at Only Lanyards, Recommend You Tackle Your Order

To round up this guide, here’s a quickfire overview of how we typically advise our customers to make their order. Systematically run through these questions, and the answers will guide your choices.

• The big one: in which settings will your lanyards be worn, and for how long?
• How far will your budget stretch? Non-standard options may inflate your overall spend.
• What are the requirements for attachments, an ID card only, or medical tools, keys and fobs?
• How pressing is the promotional element? If you’re looking to stand out at events, a longer, wider lanyard pair with an oversized card might do the trick.
• If you’re opting for a shorter strap length, have you considered how your logo will fit? A narrow 1cm lanyard works fine for staff in the office, but at an event guests will be squinting. Would a plain lanyard with a branded badge attachment suffice?
• Have you surveyed your userbase? Full length, adult lanyards won’t do if you’re outfitting petite staff or children.
• What’s most important: a hygiene-friendly, snag-free design or high-visibility?
• What about accessibility features? The design might be the right length for its wearers, but have you considered things like tactile markings or high colour contrast?
• Is colour coding a necessity? If you have higher risk areas or departments within your organisation, some colour codes could be paired with thinner straps than your regular office workers. A nifty cost-saving solution, if you ask me!
• Have you ordered samples? This is the best way to confirm your design

Conclusion: Functionality Over Aesthetics, Always

Even the most beautifully intricate, pigmented lanyard design falls apart when the hardware itself is flawed. For it to really pay off, your focus should first land on the environment, userbase, comfort and convenience you can offer. Then you can drill into the aesthetics.

So, to pull the threads of this guide together, evaluate the setting and what your lanyards need to do within it; afterwards, you can tailor your lanyard sizes to suit. This way, you ensure with 100% certainty that these lanyards won’t pose a health and safety risk, plus, get the strap material right, andthey’ll encourage staff use. All in all, a great outcome.

Frequently Asked Questions

What Is the Standard Lanyard Size in the UK?

The most common adult lanyard measures 90cm in total length, producing an approximate 45cm drop length, with a 15–20mm strap width. This suits most offices, schools and everyday workplace applications.

What Width Lanyard Should I Choose?

It depends on your priorities. 10–15mm straps are lightweight and comfortable for outdoor use, at sporting events or on-the-go activities, whilst 25mm lanyards provide greater branding space and are ideal for exhibitions, conferences and promotional events. 20mm widths, on the other hand, tend to be a suitable middle ground for typical office use.

Are Shorter Lanyards Safer?

Yes, in higher-risk environments. Shorter or adjustable lanyards reduce the chance of snagging on machinery or equipment. Where appropriate, they should also be fitted with breakaway safety clips.

What Size Are Standard ID Cards?

Most organisations use the CR80 card format, measuring 86 × 54mm. This is the same footprint as a standard bank card and fits the majority of badge holders and lanyard attachments.

Can Lanyards Be Made to Custom Sizes?

Absolutely. Custom lengths and widths are available to accommodate children, accessibility requirements, specialist workplaces or promotional campaigns where standard sizing isn’t suitable.

Should Event Lanyards Be Longer or Wider?

For most conferences and exhibitions, a 90–100cm lanyard with a 20–25mm width provides excellent visibility while leaving enough space for logos and sponsor branding.

How Do I Know Which Size Is Right for My Organisation?

Start by considering where the lanyards will be worn, what they’ll carry, who will wear them and whether safety or branding is your highest priority. Ordering a small sample before committing to a full production run is often the best way to confirm your choice.

Do Accessories Affect the Ideal Lanyard Size?

Yes. Heavy keys, access fobs, radios or multiple ID cards can alter how a lanyard hangs. In these cases, a stronger attachment and carefully chosen length will improve both comfort and durability.
