A beautiful press-on set starts with the right fit! Proper sizing helps your nails look natural, feel comfortable, and stay securely in place.
To place a custom or made to order set, we must know the accurate sizes for your unique nails!
There are three ways to find your sizes. Choose whichever method works best for you
1. The Sizing Kit — Our Recommended Method
For the easiest and most precise fit, we recommend ordering a Trinity Tipz sizing kit.
Step 1: Choose your shape and length.
Select the nail shape and length you plan to purchase. Each shape and length has its own unique sizing, so make sure your sizing kit matches your intended order.
Step 2: Try on your sample nails.
Place each sample tip over your natural nail to find the best-fitting size. Repeat for all ten fingers.
Step 3: Record your sizes.
Write down the corresponding size number for each finger on both hands.
For example:
- Right Thumb: 2
- Right Index: 5
- Right Middle: 4
- Right Ring: 5
- Right Pinky:
Repeat for your left hand.
Step 4: Keep your sizing information!
Once you've found your sizes, save them somewhere convenient. You can reuse your sizing information when ordering future sets in the same shape and length.
A little thank-you from us: Your sizing kit purchase includes a one-time coupon for the full purchase price of your kit to use toward your first nail order!
2. The Quarter Method — A Convenient Alternative
Don't want to purchase a sizing kit? No problem! You can send us photos of your natural nails using a standard U.S. quarter as a size reference.
A U.S. quarter measures 24 mm across and gives us a reference point to help estimate your nail sizes.
Step 1: Grab a quarter.
Use a standard U.S. quarter.
Step 2: Photograph your fingers.
- Place your hand flat on a surface.
- Keep your fingers relaxed and slightly separated.
- Position the quarter beside your fingers.
- Take a clear photo directly from above.
- Make sure your entire hand and the quarter are visible.
Step 3: Photograph your thumb separately.
Place your thumb beside the quarter and take another clear overhead photo.
Step 4: Send us your photos!
Send your photos to Trinity Tipz with your order or through our messaging options. We'll use the quarter as a reference to help determine your sizes.
Photo tips:
- Natural lighting works best.
- Keep your camera directly above your hand.
- Avoid filters, zoom, and angled photos.
- Make sure the entire quarter is visible.
- Send clear photos of both hands and a separate photo of each thumb.
Please note: The quarter method provides an estimate rather than an exact measurement. For the most precise fit, we recommend a sizing kit.
3. Measure Your Natural Nails
Prefer to measure your nails yourself? You can use a soft measuring tape to determine your nail widths in millimeters.
Step 1: Start with clean, dry nails.
Make sure your natural nails are clean and dry before measuring.
Step 2: Find the widest part of each nail.
Using a soft measuring tape, measure straight across the widest part of your natural nail, from side to side.
Keep the tape straight across the nail rather than wrapping it around the curve.
Step 3: Record your measurements.
Write down each measurement in millimeters (mm).
Measure all ten nails individually:
- Right Thumb
- Right Index
- Right Middle
- Right Ring
- Right Pinky
- Left Thumb
- Left Index
- Left Middle
- Left Ring
- Left Pinky
Remember that corresponding fingers on opposite hands may have different measurements!
Step 4: Find your corresponding size.
Compare your measurements with the sizing chart for your chosen nail shape and length. Each chart will help you match your measured nail width to the appropriate press-on size number.
Double-check your measurements before submitting your order.
Important Things to Know
Every shape and length has its own sizing.
A size 0 in Almond is not necessarily the same width as a size 0 in Coffin, Square, or Stiletto.
Always use the sizing information for the exact shape and length you intend to purchase.
Your hands aren't necessarily identical.
Don't assume your left and right hands use the same sizes. Measure or test each finger individually.
Still unsure? We're happy to help!
You don't have to figure everything out alone. You can send us clear photos using the quarter method, or reach out with your measurements. We'll do our best to help you find your perfect fit.
We want you to love the way your nailz fit, feel, and look!
