SIZE GUIDE

Guessing the size? Not necessary. Got it wrong? No worries.

Size Guide for Surprise Gifts

Not sure about the size? We’ve got you covered — the surprise stays a surprise.

KOTAOSTA is all about emotions.
But if you want the ring to fit perfectly from the start, here are 4 simple and discreet ways to measure your loved one’s finger size — without spoiling the surprise.

1. Scan a ring using an app

If you have access to a ring she already wears:

  • Open an app like
    Ring Sizer by Jason Withers
  • Place the ring directly on your phone screen and match it to the right size

📲 Fast, easy, accurate — and 100% stealth

2. Place her finger on your phone screen

If you don’t have a ring but can gently compare her finger:

  • Open a sizing app or size chart on your phone
  • While she’s asleep or resting, carefully place her finger on the screen
  • Align her finger with the circles to estimate the size
  • Or take a photo of her finger and send it to us — we’ll help!

💤 Works great at night — just a little light and finesse required

3. Ask someone close

A sister, friend, or mother might already know — or can help find out:

  • Have them casually try on rings together at a store
  • Ask them to take a photo of her hand with a ring
  • Or ask directly — without giving away the surprise

💡 Your secret allies can make the difference

4. Print out our sizing template

  • Download and print our PDF ring size chart
  • Place her ring on the circles and find the closest match
  • Or use the included paper strip to measure her finger discreetly

👉 Download the Ring Size Template (PDF)

🖨️ Simple and accurate — just follow the instructions carefully

Still not sure?

KOTAOSTA rings are made to adapt.
If the size isn’t perfect — we’ll replace it for free.

Buy it. Gift it. Enjoy the moment. Size is never an issue.
