What You'll Need

  • An iPhone with the Taglia di anellor app installed (free on App Store) — for the most preciso method
  • An existing ring that fits the finger you want to misurare — preferred method for app-based misurazione
  • OR: a piece of string/paper strip and a ruler — backup method if you don't have a ring to misurare
  • Good lighting and a flat surface — ensures preciso misurazione

Method 1: Using the Taglia di anellor App (Most Preciso)

The Taglia di anellor app uses smartphone screen calibration technology to misurare your taglia di anello with sub-millimeter precisione. This is the most reliable method for phone-based misurazione.

1.

Download the Taglia di anellor App from the App Store

Visit the App Store and search for "Taglia di anellor" (App ID: 6739887211). The app is completely free with no hidden charges. Download and install it on your iPhone.

2.

Open the App and Select "Misurare with Ring"

Launch the Taglia di anellor app and tap the "Misurare with Ring" option. The app will ask for permission to use your camera and access calibration data for your specific iPhone model.

3.

Place Your Ring Flat on the Phone Screen

Take an existing ring that fits the finger you're misurazione. Gently lay it flat on your phone screen, positioning it so the app can see the inner edge clearly. The inner diametro of the ring is what determines your taglia di anello.

4.

Adjust the On-Screen Circle to Match the Ring's Inner Edge

The app displays a circle that you can resize with your finger. Adjust this circle until it perfectly aligns with the inner edge of your physical ring. Take your time with this step—precision here ensures precisione.

5.

Read Your Size in Your Preferred System

The app instantly displays your taglia di anello in multiple formats: Taglia uss, Taglia uks, Taglia eus, and millimeter diametro. Scegliere the system you need for your purchase.

6.

Verify by Repeating the Misurazione 2-3 Times

Lift your ring off the screen, reposition it, and misurare again. Repeat this process two to three times. Your misurazioni should be consistent. If you get slightly different readings, take the middle value as your most preciso size.

Pro Tip: Make sure your phone screen is clean before misurazione—dust or smudges can interfere with the misurazione. Also ensure the ring sits completely flat on the screen with no gaps between the ring and the display surface. Position yourself in a well-lit room, but avoid direct sunlight on your phone screen, which can create glare.

Method 2: String Method with Phone Ruler (Alternative Verification)

If you don't have an existing ring to misurare or want to verify your app-based misurazione, the string method is reliable and requires only household items. This is the ideal backup method for Android users or anyone without the app.

1.

Cut a Thin Strip of Paper or Use Non-Stretchy String

Tear or cut a narrow strip from a sheet of paper, or gather a piece of non-stretchy string like dental floss or thin cotton string. The material should be flexible enough to wrap around your finger but not stretchy, as stretchy materials will give inpreciso misurazioni.

2.

Wrap It Snugly Around the Base of the Finger

Wrap the string or paper strip around the base of the finger you're misurazione. The key is "snug but not tight"—it should fit comfortably without leaving a mark or feeling constrictive. This is different from the way you'd wear a ring: misurare at the widest part of the base, not over the knuckle.

3.

Mark Where the Paper/String Overlaps

Hold the string or paper in place with one hand and use a pen to mark where the ends overlap. This overlap point is your circonferenza misurazione.

4.

Misurare the Length in Millimeters Using a Ruler

Lay the string or paper on a ruler and misurare from the starting point to your mark in millimeters. This is your circonferenza dell'anello. For best results, use a metric ruler for precision.

5.

Convertire Your Circonferenza to Taglia di anello

Use a taglia di anello conversionee tabella to match your circonferenza misurazione to a taglia di anello. For example, 52mm circonferenza typically equals Taglia us 6, UK L, or Taglia eu 52. You can also divide your circonferenza by 3.14159 to get the diametro in millimeters, then riferimento a size tabella.

Common Mistakes to Avoid

  • Wrapping too tightly: The string should be snug, not constrictive. A tight wrap will give you a size that's too small and won't fit comfortably when you wear the ring.
  • Misurazione over the knuckle: Misurare at the finger's widest point below the knuckle, not across the knuckle joint, which is larger and will skew your misurazione.

Q

Different sizes each misurazione?

Solution: This is normal with manual misurazione. Repeat your misurazione three times and take the middle reading as your official size. If all three readings differ by more than half a size, ensure you're misurazione correctly—consistent inconsistency points to technique issues.

Q

Ring slides around on the phone screen?

Solution: Clean your phone screen with a soft cloth to remove dust and oils. Press the ring flat against the screen with gentle downward pressure. Misurare in a well-lit room without glare. If your phone case is raised, you may need to remove it temporarily to get a flat surface.

Q

Your misurazione falls between two sizes?

Solution: Scegliere the larger size if you prefer wider fascia rings or thicker fascias, as these will feel tighter. Scegliere the smaller size if you prefer thinner fascias or delicate rings. If you're buying an engagement ring, consider comfort fit rings which are slightly roomier, and size up if between sizes.

Q

Your finger seems different sizes at different times?

Solution: This is completely normal. Fingers swell during the day due to temperature changes, activity level, and hydration. Always misurare in the evening at room temperature when your fingers are at their largest. This ensures your ring will fit comfortably throughout the day.

Q

No existing ring to misurare?

Solution: Use the string method to misurare your finger directly, then cross-check your result with the Taglia di anellor app using a friend's ring or by visiting a jewelry store to confirm. This two-method approach gives you confidence in your misurazione.
