How to Choose the Correct Ring Size for Your NFC Ring

Choosing the correct ring size is essential for comfort, durability, and daily usability, especially when you’re investing in a functional ring like the TNG NFC Ring, Ceramic Looks NFC Ring, or a Fully Customized NFC Ring.

A ring that fits perfectly ensures a better daily experience for:

Touch ’n Go payments
Public transport such as MRT, LRT, and Komuter
Parking and access systems
Digital NFC business card sharing
Everyday wearable comfort

In this guide, we’ll show you how to measure your ring size accurately and convert it to US ring size, the standard size used for most custom rings, smart rings, and NFC rings.

Why US Ring Size Is Important for NFC Rings

US ring sizing is widely used for:

Online ring purchases
Handcrafted and made-to-order rings
Smart rings and NFC rings
International size consistency

All our products, including the TNG NFC Ring, Ceramic Looks NFC Ring, and Fully Customized NFC Ring, are produced based on US ring size standards to ensure better accuracy, comfort, and consistency.

Measuring correctly is very important because NFC rings are usually custom-sealed, handcrafted, and non-resizable after production.

Once the ring is completed, the size cannot be adjusted like a normal metal ring. That’s why choosing the correct size from the beginning is the most important step before placing your order.

Method 1: Measure Your Ring Size Using a Paper Strip

This is a simple method you can do at home using paper or string. It is suitable for customers who want to estimate their ring size before ordering.

What You’ll Need:

A thin strip of paper or string
Pen or pencil
Ruler with millimeter measurement

Step-by-Step Guide:

Wrap the Paper Around Your Finger
Wrap the paper around the base of your finger where you plan to wear your TNG NFC Ring or Ceramic Looks NFC Ring.Make sure it feels snug, but not too tight.
Mark the Overlap Point
Use a pen to mark the exact point where the paper overlaps.
Measure the Length
Lay the paper flat and measure the length in millimeters (mm).
This measurement is your finger circumference.
Convert to US Ring Size
Match your measurement with a US ring size chart to find your recommended size.

✅ Best for:
Customers who want a quick home measurement before ordering a custom NFC ring.

⚠️ Important Tip:
Do not pull the paper too tightly. Your ring should be comfortable enough to wear daily but secure enough not to slip off easily.

Method 2: Measure an Existing Ring

If you already own a ring that fits your finger perfectly, this method is fast and reliable.

What You’ll Need:

A ring that fits your intended finger well
Ruler or digital caliper with millimeter measurement

Step-by-Step Guide:

Choose the Right Ring
Select a ring that fits the same finger you plan to wear your NFC ring on.
Measure the Inner Diameter
Place the ring on a flat surface and measure straight across the inside of the ring in millimeters (mm).Make sure you only measure the inner circle, not the outer edge.
Convert to US Ring Size
Compare the inner diameter measurement with a US ring size chart to find the closest matching size.

✅ Best for:
Customers who already have a comfortable ring and want to order a similar fit for their Ceramic Looks NFC Ring, TNG NFC Ring, or Fully Customized NFC Ring.

⚠️ Important Tip:
Different fingers may have different sizes. A ring that fits your left hand may not fit the same finger on your right hand.

✅ Best for:
