Which size of button badge is best?

Here are some key things to consider when choosing the best size for your needs.
 
1. Small badges are more subtle but also more fashionable.
Two round pins—one with a cartoon person on orange, one with a red apple on white—are next to a yellow measuring tape showing a length of about 2 inches.

The 25mm size badge is considered to be the classic “one inch button”, timelessly fashionable so a great choice for brands, musicians and artists. The small size makes them great for striking logos and simple, eye catching designs, and it also makes them the most likely to be worn as a fashion accessory.

We also class 32mm diameter badges as small buttons. They retain the wearability from not being overly large, but do have a little more of a canvas to work with.

    1. The 25mm size has a wire d-pin not a standard safety pin

The 25mm size button badge is the only button badge that features a wire d-pin rather than a safety pin.

The wire d-pin is designed to allow the wearer to rotate the pin into the position that they prefer. The badges won’t arrive with the all of the pins oriented to the artwork. Instead the pin can be rotated as required.

For a small badge with a fixed position standard safety pin, opt for the 32mm size.

  1. Larger badges are better for communicating a message or promoting an idea.

38mm or 45mm diameter sizes give a little more scope to communicate a slogan or marketing message.

The artwork can include more lettering and more complexity but still maintain visual impact. These sizes are perfect for membership tokens or advertising events.

  1. 38mm size badges can have a kidsafe clip instead of a standard safety pin.

38mm is the only size that has a chunky kidsafe clip option available.

  1. 5. Really big badges can carry lots of information to see across a crowded room.

58mm or 77mm diameter badges allow room for complicated messages, and can also provide a way to promote a message across a room.

These large sizes are popular for staff to wear for corporate promotions, or of course if you are looking to make the biggest possible impact when the badges are worn, for example if the badges are for a party of celebration.

6. Rectangle and Square shapes offer additional choices.

 
Beyond the six circular sizes, the square and rectangle shapes offer two further badge sizes to pick from: 38mm x 38mm square and 70mm x 45mm rectangle.
 
The square shape makes for a quirky badge that is a little bit different to the norm, while the rectangular badge provides a large enough space to work as an effective name badge or to carry helpful information.
