KEY TAKEAWAYS
- Wrap a thin thread or paper strip around your finger, mark where it meets, and measure in mm
- That measurement is your finger circumference. Use the conversion chart below to find your US size
- Always measure in the evening when fingers are slightly larger
- Between sizes? Go slightly larger for a more comfortable fit
Why Getting the Right Size Matters
When you’re shopping for a ring online, getting the size right makes all the difference. A ring that’s too tight will pinch and feel uncomfortable, and one that’s too loose might slip off when you least expect it. Since every ring I make at Valltasy is one of a kind, I want to make sure it fits you perfectly from the moment you put it on.
The good news? You don’t need to visit a jeweler or buy any special tools. Everything you need is already at home. I’ll walk you through two simple methods, and in just a couple of minutes you’ll know your exact size.
Two Easy Methods to Measure at Home
I always tell my customers to pick whichever method feels easiest. Both give you the same result, so just go with what you have handy.
Method 1: The Thread Method
- Take a thin thread, piece of string, or dental floss. Nothing too thick, you want it to sit flat against your skin.
- Wrap it gently around the finger where the ring will sit. Make sure it’s snug but not tight, you should be able to slide it around just a little.
- Mark the point where the thread meets with a pen or marker.
- Lay it flat and measure the length in millimeters (mm) with a ruler. This number is your finger circumference.
Method 2: The Paper Strip Method
- Cut a thin strip of paper (about 1 cm wide and 10 cm long). Regular printer paper works great.
- Wrap the strip around your finger and mark where the end overlaps with a pen.
- Lay the strip flat on a ruler and measure the distance from the edge to your mark in millimeters.
This method is great if you don’t have thread or string around. The paper holds its shape better too, which makes it a little easier to mark accurately.
EXAMPLE
If your measurement is 52 mm, your EU size is 52 and your US size is 6. Easy! Once you have your circumference, just check the conversion chart below and I’ll take care of the rest.

Wide Bands vs Thin Rings
This is something a lot of people don’t realize, and it can make a real difference in comfort. A wider band covers more of your finger, so it naturally feels tighter than a thin ring of the same size.
My rule of thumb:
- Thin bands (under 4 mm) – your measured size should be perfect as is.
- Medium bands (4-6 mm) – consider going up a quarter size for extra comfort.
- Wide bands (over 6 mm) – I recommend going up a half size. Trust me, your finger will thank you!
If you’re ever unsure which category a ring falls into, just ask me and I’ll let you know.
Tips for a Perfect Fit
A few small things can make a big difference when measuring your ring size. Here’s what I always tell my customers:
- Measure in the evening because your fingers are slightly larger in the evening than in the morning.
- If your knuckle is wider than the base of your finger, measure both spots and pick a size somewhere in between.
- Between sizes? I always recommend going with the slightly larger size. A ring that’s a tiny bit loose is way more comfortable than one that pinches.
- Avoid cold hands because cold temperatures make your fingers shrink. Warm them up first for the most accurate measurement.
- Don’t pull the thread too tight because comfort is key! You want the ring to slide on smoothly, not squeeze.
- Measure more than once because temperature, humidity, and even what you’ve eaten can affect finger size. Measuring 2-3 times on different days gives you the most reliable result.
Measuring for Someone Else
Planning a surprise? I love that! Here are a few sneaky ways to find out someone’s ring size without giving away the secret:
- Borrow a ring they already wear on the same finger. Slip it onto a pencil and mark where it stops, then measure the diameter. Multiply by 3.14 to get the circumference.
- Press one of their rings into a bar of soap or trace the inside circle on paper. This gives you an imprint you can measure later.
- Ask their friends or family. Sometimes the simplest way is the best. They might already know!
- When in doubt, go slightly larger. It’s much easier to resize down than up, and a slightly loose ring is more comfortable than a tight one.
And if all else fails, you can always reach out to me and we’ll figure it out together. I’ve helped plenty of people find the perfect surprise ring! If you’d like something truly unique, explore my custom ring options.

COMMON QUESTIONS
Ring Size FAQ
What's the most common ring size?
For women, the most common ring sizes fall between US 6 and US 7 (EU 52-54). For men, it’s usually between US 9 and US 11 (EU 59-65). But everyone is different, so I always recommend measuring rather than guessing!
What if I don't have a ruler that measures in millimeters?
You can use a regular inch ruler and convert! Measure in inches, then multiply by 25.4 to get millimeters. Or just take a photo of the thread next to any coin (for scale) and send it to me. I’ll figure it out for you.
Can I measure using an existing ring?
Yes! Place a ring that fits well on a ruler and measure the inside diameter in millimeters. Then multiply by 3.14 (pi) to get the circumference. For example, if the inside diameter is 17 mm, the circumference is about 53 mm, which is roughly a US size 6.25.
Do ring sizes vary between left and right hands?
They can! Your dominant hand is usually slightly larger. Always measure the specific finger on the specific hand where you plan to wear the ring.
Will my ring size change over time?
It can change due to weight fluctuations, temperature, pregnancy, or even the time of day. That’s why I recommend measuring a few times before ordering. If you’re ever unsure, just ask me!
How do I know if a ring fits correctly?
A well-fitting ring should slide over your knuckle with just a little bit of resistance, then sit comfortably at the base of your finger. It shouldn’t spin around freely, but it also shouldn’t leave a mark or feel like it’s squeezing. Think snug, not tight.
What if the ring doesn't fit when it arrives?
Don’t worry! Since every ring I make is one of a kind, I’m always happy to help find a solution. Get in touch and we’ll work it out together.
