How to Measure Press-On Nails Size

It’s great that you have decided to go for the press-ons gig, but you have just encountered your biggest obstacle yet. In terms of size, how will you determine which size you need? I’m assuming you’re here to figure out the fastest, easiest way to size your press-ons. Isn’t it? Is it 10, 12, 20, 24, or what the heck?


To order your nails, you have the option of choosing the nail size that is appropriate for you. This means getting false nails that don’t fit is no longer an issue! In case you are wondering about the size you need, do not fret! You can simply measure your nails to find out what size you need.

In this press-on nail tips blog post, I’m going to cover the most often asked question:

“How to measure press-on nails size?” Let’s dive into it!

4 Ways to Sizing Press-on Nails for Your Client

Listed below are 4 different sizing options, and I’ll just say right off the bat that they are all a bit time-consuming.


Most people are having clients send in their nail tips measurements. Send your clients a sizing kit or have them pick it up from you. The kit can be sold as a separate item or it can be bundled into your set’s price. This option takes a great deal of time and communication.

It would be beneficial to mail sizing kits. When you focus intensely on only 10 nail tips, you get the most accurate sizing fit, and your client can also practice applying and gluing at home. If possible, you should send her all 10 tips for her desired length & shape. You could also send 10 extra tips of a different size & shape if she was interested in more than one style; in this case, you should and could charge extra.

However, this option may have some cons:

  • The process might be a bit stressful, especially if you are also working on another set of nail tips at the same time. If things get hectic, it will certainly be a challenge!
  • There is no extra nail tip to put on if a nail comes off, they lose track of it, and it goes missing! Reusability is almost nil once a nail goes missing.


Your customers might find it useful to see a short clip about how to size their nail beds. You can find this really cool tip online where you take a piece of Scotch tape and mark markings and then you take the tape and place it on a flat surface and measure the thickness in millimeters (for example, multiply the centimeter side of the ruler by ten).

According to me, this is a much better option. There is no need to know what size and style your customer wears since you are going by her natural nail bed, which does not change. You can send her another nail tip or two if you are unable to choose between sizes since it is your responsibility to size her properly.

You can custom design a set of up to 10 nail tips (or 12… if you’re nice with it). It also saves you time and money since you won’t have to wait for the mailing kit to arrive for your client or spend extra money to mail a sizing kit.

Some cons of this option:

  • You still have to wait for your customer to sit down and complete this complicated measuring process per your instructions.
  • In that scenario, she’ll either take longer to submit or even get cold feet about this whole press-ons business if she doesn’t have tape or a ruler.


Provide sets of various sizes. You should contemplate sizes like small, medium, or large. It will be most flexible for you and your clients. In the set of small-size press-ons, you will also include thinner nails, like size 2 and 5-9, 2. The medium set will feature 0-7, while the large set can house double-zeroes through size 5. You can offer 2 of each for every size (small, medium, or large). 

So, in total, you will create between 14 and 18 tips. Once again, your client gets a few extra tips, plus the margin of error for sizing is still low. Your client would probably be immensely happy with this offer. 

One of the greatest benefits of this option is that you avoid the need to communicate back and forth, which will only result in a pause in the production process.

Cons for measuring size with this option:

  • Compared to the pros, the cons of this option are relatively minor. You will need to update the cart drop-down options to include SML and the tip shapes attached to the different sizes.
  • Moreover, you are also investing more time in creating more tips.


Create ready-to-ship sets that only include your most popular designs as you go into full production mode. Not only will you be creating different nail tip sizes, but you will also be creating some doubles. In middle sizes, for instance, the size may be the same on the ring and index as well as the middle and ring, and so you’ll need 4 #4s rather than 2. As for size 4, I believe it to be the most universal since almost all your clients will need a size 4.

If you use sizing option #4, there is no communication between your client and yourself, and you become a full-blown production machine, where your client is able to jump on and shop when you release. A very minor cons this option has!

A Few Final Thoughts

It was mentioned at the beginning of this article that there is no easy way, but this does not mean there isn’t a halfway point. I believe option 3 is that halfway point. In conclusion, I would simply recommend you an easy method how customers themselves can measure their press-on nail size if they do not have a soft measuring tape. What you need to do is just to measure the width of your nail at the widest part. Follow the steps below:

  • First of all, you should place a small piece of tape along the width of your nail.
  • Mark the widest point of each side of your nail on the tape using a pen.
  • Remove the tape after measuring the distance between two points in millimeters with a ruler.
  • Be sure to record your measurements in millimeters!

Simply measure and compare your measurements with a sizing chart in the shop.
