1/16″ Bubbles that are 1/16th of an inch in thickness and 1/8th of an inch in diameter provide very little protection and are used for wrapping small, fragile items, such as glassware. You can double or even triple wrap for additional protection if needed, but these super small bubbles are mainly to protect from scratches or surface damage.
1/8″ This size is a nice option for small or easily scratched items that need a little extra protection, but not much.
3/16″ This is the most common size for bubble wrap. It is 3/16th of an inch in size with 3/8” of an inch diameter. It is ideally suited for light to medium weight items.
5/16″ This option has a 1 inch diameter, which makes each bubble quite large. You can easily fill in lots of space in boxes while adding a significant amount of cushioning to protect your belongings.
1/2″ This is the largest option that you can normally find. With a 1/2 inch depth and 1¼ inch diameter it will fill up space and can help provide a significant amount of protection for medium-weight items.
PRO TIP: For maximum protection, place the actual bubble directly against your item rather than the flat surface of the wrap.
