Quick answer: An industrial barbell needs the right gauge, wearable length, and alignment for both piercings. A 38mm bar is one available size, not a universal industrial fit.
A straight bar connects two placements, so its fit is more involved than choosing a decorative end. Before browsing colors and charms, record the dimensions and construction your piercer has confirmed.
Understand wearable length
Wearable length describes the usable bar between the ends, rather than the complete end-to-end length including balls or decorations. Product conventions can vary, so ask if the listing is unclear. Measuring the outside of two ball ends and comparing that number to wearable length can lead to the wrong order.
Why gauge alone is insufficient
Two industrial bars can share a gauge while differing in length. Conversely, two bars can have the same length but different thicknesses. Both dimensions need to match the intended fit. Neither can tell you whether the bar aligns with the angle and spacing of your two piercing channels.
Bring a comfortable reference piece
Your piercer can measure existing jewelry and explain what, if anything, should change. If a bar seems to press against the ear or leaves excessive exposed shaft, describe that concern instead of choosing a random shorter replacement. A photo can illustrate your preferred look but cannot replace an anatomy assessment.
Compare decorative profiles
A charm or sculpted center adds another dimension to a straight bar. Check whether the decoration is fixed or movable and whether it changes how the piece sits. Glasses, hair, headwear, and headphones are useful practical considerations. A dramatic center detail should be assessed as part of the whole assembly.
Read the selected variant carefully
Kruelty’s Industrial Barbell collection contains multiple lengths and gauges. One listed pack offers 14G industrial barbells at approximately 38mm. That listing is an example of available dimensions, not a recommended size for everyone. Check the actual option selected in the cart and whether the package contains a complete bar, spare ends, or a multi-piece set.
Compare length without including the decorative ends
A bar described as 1½ inches is approximately 38.1mm before retail rounding. If you measure a loose piece from the outside of one ball to the outside of the other, you include the ends and cannot compare that number directly with wearable length. Have the usable shaft measured instead.
Make a second check for the bar's path across the ear. A longer bar does not automatically correct a center decoration pressing against the ear's flat area; alignment and anatomy may be the issue. Record whether a central charm is fixed or movable and where headphone cushions or glasses touch. Bring those details to a fitting instead of ordering several lengths to troubleshoot pressure yourself.
Frequently asked questions
Is 1½ inches the same as 38mm?
It is approximately 38mm. Use the seller’s stated measurement and confirm the required fit with your piercer.
Can I replace one industrial bar with two separate studs?
Ask your piercer before changing the setup; independent jewelry and a connecting bar behave differently.
