How to Choose Press On Nail Size


So, you’ve decided to dive into the fabulous world of press on nails. Great choice! These little beauties can give you salon-quality nails in minutes without the hefty price tag. But here’s the thing: if you want them to look amazing and stay put, you need to get the sizing right. Choosing the wrong size can lead to discomfort, nails popping off, or worse, looking completely unnatural. Don't worry, though; I've got you covered. Let’s walk through everything you need to know to choose the perfect press on nail size.

Why Choosing the Right Size Matters

Benefits of Well-Fitted Press On Nails

Getting the right size press on nails isn’t just about aesthetics (though, who doesn’t want their nails to look fabulous?). Well-fitted nails will:

  • Feel Comfortable: They won't press against your natural nails or cuticles, avoiding pain or discomfort.
  • Stay Secure: Properly sized nails are less likely to pop off at the worst times—like when you're showing off your new nails.
  • Look Natural: When nails fit correctly, they blend seamlessly with your natural nail shape and size, giving a polished and professional look.

Drawbacks of Poorly Fitted Press On Nails

On the flip side, poorly fitted nails can be a nightmare. Here’s what you might face:

  • Discomfort and Pain: If they’re too small or too big, they’ll press against your nail beds and cuticles, causing discomfort or even pain.
  • Short Lifespan: Ill-fitting nails are prone to lifting and popping off, which means you'll be constantly reapplying or losing nails.
  • Unnatural Appearance: Misaligned nails can look awkward and unnatural, defeating the purpose of having press on nails in the first place.

Understanding Press On Nail Sizes

Standard Sizing Systems

Most press on nails come in a range of standard sizes, usually numbered from 0 to 9. Size 0 is typically the largest, while size 9 is the smallest. Knowing your size in one brand might help as a rough guide for others, but there can be slight variations, so it’s always good to check each brand’s size chart.

Custom Sizing Options

Some brands offer custom sizing where you can order nails specifically tailored to your measurements. This is perfect if you have nails that don't quite fit into standard sizes, providing a more personalized and precise fit.

Measuring Your Natural Nails

Tools You'll Need

Before you start, gather these simple tools:

  • A flexible measuring tape or a ruler
  • A piece of clear tape
  • A fine-tipped pen or marker

Step-by-Step Measuring Guide

  1. Prepare Your Nails: Ensure your natural nails are clean and free of polish.
  2. Use the Tape Method: Place a piece of clear tape across the widest part of your nail.
  3. Mark the Width: Use the pen to mark where your nail starts and ends.
  4. Measure the Tape: Remove the tape and measure the distance between the marks with your measuring tape or ruler. Note this measurement in millimeters.

Common Mistakes to Avoid

  • Inaccurate Marking: Ensure your marks are precise; even a millimeter can make a difference.
  • Not Measuring All Nails: Each nail can have slightly different sizes, so measure all your nails individually.

Comparing Measurements to Size Charts

Interpreting Size Charts

Most brands provide a size chart that translates your nail measurements into their size numbers. Match your measurements to the closest size on the chart.

Adjusting for Different Brands

Different brands might have slight variations in their sizing. Always refer to the specific size chart for the brand you’re using. When in doubt, err on the side of a slightly larger size that you can file down.

Testing Fit Before Application

Dry Fit Method

Before applying any adhesive, place the press on nails over your natural nails to check the fit. They should cover your nail completely without overlapping onto your skin.

Wet Fit Method

For a more accurate test, apply a tiny dot of nail glue or a nail tab and press the nail on briefly. This will give you a better feel of how the nail will sit once fully applied.

Customizing Press On Nails for Perfect Fit

Filing and Shaping Techniques

If the nails are a bit too wide or long, don’t worry. You can file them down to better match your natural nails. Use a nail file to gently shape the edges and shorten the length as needed.

Using Nail Tabs or Glue for Better Fit

Sometimes, using nail tabs instead of glue can help achieve a better fit, especially if you need to slightly adjust the placement. Nail tabs also make it easier to remove and reuse the nails.

Maintaining Your Press On Nails

Daily Care Tips

  • Avoid Excess Water: Too much exposure to water can weaken the adhesive. Wear gloves while doing dishes or cleaning.
  • Be Gentle: Avoid using your nails as tools. This means no prying open cans or scraping off stickers.
  • Moisturize: Keep your hands and nails moisturized, but avoid oils directly on the press on nails as they can break down the adhesive.

Long-Term Maintenance Strategies

  • Touch-Ups: Keep a nail file and glue handy for any quick fixes if a nail starts to lift.
  • Regular Breaks: Give your natural nails a break between sets to keep them healthy.

Troubleshooting Common Issues

Nails Popping Off

If your nails keep popping off, it might be due to:

  • Poor Adhesion: Ensure your natural nails are clean and dry before application.
  • Wrong Size: Double-check your sizing to ensure they fit properly.

Nails Feeling Uncomfortable

Discomfort often means the nails are too small or improperly shaped. Try resizing and reshaping the press on nails for a better fit.


Choosing the right press on nail size might seem daunting at first, but with a little patience and practice, you'll get the hang of it. Properly sized nails not only look fabulous but also feel comfortable and last longer. So, take your time measuring and fitting, and you’ll be rocking those stunning nails with confidence in no time!


  1. How often should I change my press on nails? Ideally, every 1-2 weeks, but this can vary based on how well you maintain them and the type of adhesive used.

  2. Can I reuse press on nails? Yes, if they’re in good condition and you used nail tabs or gentle adhesive, you can clean and reuse them.

  3. What if my nails are between two sizes? Opt for the larger size and file it down for a better fit.

  4. Are press on nails safe for my natural nails? Yes, if applied and removed correctly. Avoid harsh adhesives and give your natural nails breaks between applications.
