Fold over elastic comes in different sizes and widths, and it can be used on various wearable items such as shoes, backpacks, and clothing. Different sizes and widths have different purposes. Fold over elastic is available in several sizes, including 1/4 inch, 3/8 inch, 1/2 inch, and 5/8 inch. Here's a breakdown of these four sizes:

1/4 inch (6.35 millimeters): This is one of the most common sizes of fold over elastic. It is typically used for lightweight applications such as baby clothing, lingerie, and hair accessories. The 1/4 inch wide fold over elastic is suitable for small edges and details.

3/8 inch (9.53 millimeters): This size of fold over elastic is slightly wider than the 1/4 inch size and is more suitable for applications that require stronger support. It can be used for lightweight to medium-weight clothing, home goods, and crafts.

1/2 inch (12.7 millimeters): The 1/2 inch wide fold over elastic is a versatile size suitable for various applications. It can be used for clothing (including lingerie, swimwear, and activewear), home goods, packaging, crafts, and more. This size of fold over elastic provides a broader support area and is suitable for multiple purposes.

5/8 inch (15.88 millimeters): The 5/8 inch wide fold over elastic is typically used for applications that require greater support, such as sportswear, backpacks, hats, and more. It provides a wider area to maintain item stability and fastening.

In addition to the listed sizes, there are wider options available, such as 3/4 inch (19.05 millimeters) and 1 inch (25.4 millimeters). These wider sizes are often used for larger items or applications that require stronger support.

Apart from the four common sizes mentioned above, there are other sizes available as well. When choosing fold over elastic, it is important to consider the specific application and select the size accordingly, as different purposes require different size ranges.
