These are international
standards for measuring Body jewellery
It is exactly how
Lindy's Goodies measure - using digital calipers
If you are unsure
what your requirements are, ask a qualified Piercer for help.
The below picture indicates
measurements which are used for all straight bars such as those used for Tongue
and Industrial piercings. Seen here is a barbell which is 4g 16mm with 10mm
Above a jewelled ball captive ring is
pictured. Measurements indicate this captive ring to be 14g 14mm.
Here we see a typical eyebrow bar -
the measurement for the length is taken on the shorter side and includes only
the bar, not the length including the balls. This piece is 16g, 10mm. The same
measurement technique is used to measure belly bars.
Expanders are measured at their
widest part - here is a 10mm (00g) acrylic expander.
Pictured above is a Horseshoe
(CBB - circular barbell) ring with Internal Thread Balls (the thread is attached
to the ball, rather than the ball having the hollow inside). This captive would
be described as 8g, 22mm.
Here we see a Saddle Plug - it's
important to understand that these are measured at the 'waist' as indicated
Tunnels are measured at the central
part of the jewellery. In the flexi silicone (green) it indicates this to be 8mm
(0g) and the steel, 6mm (2g).
