Before purchasing body jewelry online, it's not only super important to know what gauge you wear - but also what length or inner diameter you wear.
Fortunately, it's really easy to take these measurements at home! Gauge must be measured with a caliper, but the inner diameter and the length of a post can be measured with a ruler if you don't have a caliper (a caliper will still be the most accurate, though).
First, let's take a quick look at how body jewelry is measured:
Finding out what inner diameter you wear in nose hoops is not only really simple, but it will ensure that you get a great fitting nose ring that hugs the nostril perfectly!
Quick Tip: Measure your nose piercing without your jewelry inserted. This will allow you to clearly line up the caliper or ruler with your actual piercing hole.
The measurement that you need is the distance from the piercing hole to the edge of your nostril - measure in a straight line from the piercing hole down to the edge of your nose. This will be the smallest inner diameter hoop that you can wear comfortably, and it will fit snugly against your nostril. The most accurate way to measure your nose piercing is to use a caliper, however, you can also use a ruler if that's all you have.
To avoid the problems that come with a piece of jewelry that fits too tightly, make sure you always round up to the next whole number if the measurement you get is in between sizes. For example, if you measured a distance of 5.6mm from the piercing hole to the edge of your nose, do not buy a hoop that has a 5mm inner diameter. Instead, round up and get a hoop with a 6mm inner diameter.
Don't forget - if you're buying a beaded nose hoop, make sure you add 1mm to the smallest inner diameter that you can wear to accomodate the size of the beads that I use!
If you want your hoop earrings to fit snugly against the bottom of your earlobe, then it's incredibly important to measure your actual piercing. A hoop that hugs the earlobe is more comfortable to sleep in and is less likely to snag on clothing or hair during daily activities.
Don't want a close-fitting hoop earring? No problem! Just add 1mm-3mm to the measurement that you obtained using the above steps and you'll get a looser fit.
The two different measurements that you need to know before buying tragus studs online are: 1) the gauge that you wear, and 2) what length of post you need. The easiest way to obtain these measurements is to simply ask your piercer, but if that isn't an option you're not out of luck.
Quick Note: Traditional 20 gauge post earrings for earlobes do not work well for tragus piercings. Not only is the gauge too thin, but the post is also going to be too long to fit comfortably in your ear - most stud earrings will have a post length between 10mm and 11mm.
To find out what gauge you wear, simply use a caliper to measure how thick the stud is that you are currently wearing - the two most common gauges used for tragus piercings are 18 gauge (1.0mm thick) and 16 gauge (1.2mm thick). You must use a caliper to measure the gauge, a ruler will not work for this step.
Next, you can move on to finding out what length you wear. There are two ways to do this - you can either measure your actual piercing, or like you did with the gauge, just measure a piece of jewelry that already fits comfortably.
This is a really easy measurement to take! In a straight line, measure the distance from the piercing hole to the edge of the cartilage - this will be the smallest inner diameter that you can wear, and it will fit snugly. If you are going to get a beaded hoop, make sure that you add 1mm to this measurement to accommodate the size of the beads that I use.
