The listed length (inches" or millimetres as shown below) refers to the distance between the balls. It is the length of the piercing shaft in fractional inches/millimeters and not the length of the full body jewellery.

If you are unsure what size you are, measure a piece of navel jewellery that currently fits you correctly and assess which size show below will best fit. TIP: Most professional belly piercings are done at the standard 10mm to 11mm lengths. If your piercing was done sometime ago your piercing may have shrunk to a smaller size over the years.

Pregnancy / Maternity Belly Button Ring Size Information

As your belly grows, your navel piercing stretches. During this time, it is best to wear a flexible PTFE or Bio Flex belly ring to avoid irritation.

Tummy Toys pregnacy belly rings are a standard size 14 gauge - as per above sizing and are sold in the following lengths. Anything shorter is not recommended as you can optionally cut these belly rings to a smaller size anyway if they are far too long for your piercing. Our pregnancy belly rings are self threading and your purchase from TummyToys will include instructions on how to do this. For threading assistance please feel free to contact us.

14mmUp to 7 monthsYes
19mmUp to full termYes
20mmUp to full termYes

Gauge - width of the shaft (eg. 14g)

Navel jewellery is measured by gauges. The higher the gauge the smaller the piercing. 14g is the standard size that fits most piercings. To go upto 12g (and wider) you will need to have your piercing stretched.

The majority of navel rings sold by Tummy Toys are sold in the standard 14g size unless otherwise specified. Tummy Toys have various sizes available in the UV Flex capitves range.

16g is actually a smaller piercing gauge then 14g. Often people who leave their piercing without jewellery for too long end up switching to a 16g as their piercing partially closes, however there are far less choices in belly button rings in a 16g so retaining your 14g piercing is much more beneficial.

Refer to the chart below for specific details.
