Lanyard Sizes

Below I have discussed each size in more detail.

10 × 450 mm

For those who prefer a smaller and more discreet lanyard, the 10-millimeter width and 450-millimeter length options may be a perfect choice. This size is often used to secure small attachments such as office ID cards, card pouches, or plastic-encased name tags. 

So whether you need a lanyard for work or personal use, the 10mm x 450mm size may be just what you need to keep your important items close at hand.

Even with its smaller size can still effectively serve its primary purpose of displaying important information for security and recognition.

15 × 450 mm

If you’re looking for a lanyard size that is slightly wider than the 10mm option but still suitable for smaller necks, the 15mm x 450mm lanyard may be a perfect choice. While only a few millimeters wider than the previous size, this lanyard is commonly used as a name tag holder for kids. 

Whether your child needs a lanyard for a school event, birthday party, or any other occasion, this size offers a great way to keep their name tag or ID card visible while also adding a touch of style and personality.

20 × 450 mm

Many office workers choose a lanyard that measures 20mm x 450mm and can be customized with their company’s design. This size provides ample space for creativity, allowing the company to showcase its logo and add a professional touch to the worker’s appearance. The wider width of 20mm also allows for the display of text, like a company motto or mission statement, making it a great option for events and conferences.

Other Lanyard Considerations


1. Color:

2. Material:

Lanyards can be made of various materials, such as nylon, polyester, or cotton. Each material has its own unique characteristics and strengths, so consider which material is best for your intended use. For example, if the lanyard will be subjected to harsh environments or weather conditions, a durable material like nylon may be the best choice.

3. Attachment Hardware:

Lanyards come with various attachment hardware options, such as swivel hooks, lobster clasps, or bulldog clips. Depending on what the lanyard is being used for, certain attachment hardware may be more suitable than others. For example, if the lanyard will be used to hold a badge or ID card, a bulldog clip may be the most secure choice.
