Stop Guessing Your Ring Size

4 Easy Steps

Let’s end the era of “I think I’m a size 7?”

If you have Snapchat, a ring that already fits, and 60 seconds… you can get your exact size without any guesswork.

Here’s the easiest ring-sizing tutorial on the internet — seriously.

STEP 1

Grab a Ring That Fits Perfectly

STEP 2

Open Snapchat & Take a Black Photo

STEP 3

Tap the Pen Tool & Trace the Inner Circle

STEP 4

Measure the Inner Diameter

Find the number you measured under 'diameter' in MM to the ring size in any ring size chart — and boom, that’s your size.

See?

No printing charts, no cutting paper strips, no guessing.

Just Snapchat, a ruler, and one minute.

Now that you know your exact size, you’re ready to shop confidently — and avoid the headache of returns.
