NANA ARMOUR RING Size Guide

Choosing the right size makes your NANA ARMOUR RING feel like part of you — secure, comfortable, and easy to wear all day. This guide will help you find your best size (6 / 7 / 8 / 9) in a few simple steps.

1. Quick Size Tips

If you already wear rings:

  • Look inside your favourite ring band — you may see a number like 6 / 7 / 8 / 9.
  • If that ring fits the same finger where you’ll wear your NANA ARMOUR RING, you can usually choose the same size.
  • If your current ring is a very thin band, and the NANA ARMOUR RING is wider, consider going half a size up if you’re between two sizes.

General feeling (for the ring finger):

  • Size 6 – slimmer fingers, more petite hands
  • Size 7 – most common “standard” size
  • Size 8 – slightly stronger / wider fingers
  • Size 9 – wider fingers or prefer a looser fit

2. NANA ARMOUR RING Size Chart (US Sizes)

US Size Inner Diameter (mm) Inner Circumference (mm) Typical Fit Note
6 ~16.5 mm ~52.0 mm Slim fingers, petite fit
7 ~17.3 mm ~54.5 mm Standard fit for many wearers
8 ~18.1 mm ~57.0 mm Slightly wider / stronger fingers
9 ~18.9 mm ~59.5 mm Wide fingers or relaxed fit

> If you’re between two sizes based on your measurement, we recommend choosing the larger size for this ring style.

3. Method A — Measure a Ring You Already Own

This is the fastest and most accurate method if you already have a ring that fits well.

  1. Pick your best-fitting ring Choose a ring that fits the same finger and same hand where you’ll wear the NANA ARMOUR RING.
  2. Measure the inside diameter
  • Place the ring on a ruler.
  • Measure the inside width from one inner edge straight across to the other inner edge (in millimetres).
  1. Match with the chart
  • Compare your measurement to the Inner Diameter (mm) column above.
  • Choose the closest size (6 / 7 / 8 / 9).

Example:

  • If your ring’s inner diameter is around 17.3 mm, choose Size 7.
  • If it’s closer to 18.1 mm, choose Size 8.

4. Method B — Measure Your Finger With Paper or String

If you don’t have a ring yet, you can measure your finger directly.

  1. Prepare a strip
  • Cut a thin strip of paper (or use a soft string).
  • Make sure it’s not too wide, so it wraps around your finger easily.
  1. Wrap around the base of your finger
  • Wrap it around the base of the finger where you’ll wear the ring.
  • The strip should be snug but not tight.
  • Mark the point where the paper/string overlaps.
  1. Measure the length
  • Lay the strip flat and measure from the start to your mark (in millimetres).
  • This is your finger circumference.
  1. Match with the chart
  • Compare your measurement with the Inner Circumference (mm) column.
  • Choose the closest size.

Example:

  • Circumference around 54–55 mm → Size 7
  • Circumference around 57–58 mm → Size 8

5. Fit Notes for the NANA ARMOUR RING

The NANA ARMOUR RING has an armour-style band design, which can feel a little different from a very thin, minimal ring.

  • A slightly wider band can feel more snug than a thin band in the same size.
  • If you are exactly between two sizes, or your fingers tend to swell during the day, we suggest choosing the bigger size.
  • Try to measure your finger at the end of the day, when your fingers are at their largest — this helps avoid choosing a size that’s too tight.

6. Common Questions

Q: I’m between two sizes. What should I do? A: For the NANA ARMOUR RING, we recommend going up one size if you’re in-between. A slightly looser ring is more comfortable than one that’s too tight.

Q: Which finger should I measure? A: Measure the exact finger where you plan to wear the ring. Your left and right hands can be different, and even fingers on the same hand can vary.

Q: I want to buy this as a gift. Any tips? A:

  • If the person already wears rings, secretly “borrow” one and measure it using Method A.
  • If you’re unsure, and they usually wear standard women’s ring sizes, Size 7 is often a safe starting point, while Size 8–9 work better for wider fingers or a looser look.

7. Final Check Before You Order

Before you add your NANA ARMOUR RING to the cart:

  • Confirm your size using Method A or Method B
  • Check our Size Chart one more time
  • If you’re hesitating between two, choose the larger size for a more comfor
