Finding the right ring size helps your jewelry feel beautiful from the first wear. This guide can help you measure at home, compare common ring sizes, and choose a comfortable fit before placing your order.
Viramia uses US ring sizing as the main standard. If you already know your size in another system, you can use the chart below as a reference.

How to Measure Your Ring Size at Home
Method 1: Measure a Ring You Already Own
This is usually the easiest method if you have a ring that already fits the intended finger.
- Choose a ring that fits comfortably.
- Measure the inside diameter of the ring in millimeters.
- Compare the measurement with the chart above.
- If the measurement falls between two sizes, consider the larger size for comfort.
Tip: Make sure you measure the inside edge only, not the outer edge of the ring.
Method 2: Measure Your Finger
If you do not have a ring to compare, you can measure your finger with a strip of paper or soft measuring tape.
- Wrap the paper or tape around the base of your finger.
- Keep it snug, but not tight.
- Mark where the ends meet.
- Measure the length in millimeters.
- Compare that number with the inner circumference column in the chart.
Tip: The ring should slide over your knuckle with gentle resistance and feel secure at the base of your finger.
When to Measure
For the most accurate fit, measure your finger:
- At the end of the day, when fingers are usually slightly larger.
- When your hands are at a normal, comfortable temperature.
- More than once, especially if you are between sizes.
Avoid measuring when your hands are very cold, very warm, or swollen, as this can affect the result.
Choosing Between Two Sizes
If you are between two sizes, consider how the ring will be worn:
- For a wider band, choose the larger size for a more comfortable fit.
- For a slim band, your usual size often works well.
- If your knuckle is larger than the base of your finger, choose a size that can pass over the knuckle without feeling loose once worn.
- For stacking rings, make sure each ring still feels comfortable when worn together.
If the piece is adjustable, gently adjust it only as needed and avoid repeatedly bending the band.
Ring Fit by Style
Slim Bands
Slim bands usually feel lighter and may fit true to size. They are a good choice for everyday wear and stacking.
Wide Bands
Wide bands cover more of the finger and can feel tighter. If you are between sizes, sizing up is often more comfortable.
Engagement and Statement Rings
Rings with larger stones or more detailed settings should feel secure without spinning too much. A slightly snug fit may help keep the stone centered, but the ring should not feel tight.
Open or Adjustable Rings
Open and adjustable rings offer more flexibility, but they still need a good starting size. Adjust slowly and gently to help protect the shape of the band.
International Size Note
Ring size conversions are approximate. Different jewelers and regions may use slightly different standards, so the most reliable method is to measure the inner diameter or inner circumference in millimeters.
If you are ordering a custom piece, we recommend confirming your US ring size before production begins.
Custom Ring Orders
For custom rings, sizing is especially important because the piece is made for your order. Please check your size carefully before confirming your design.
If you are unsure, we recommend visiting a local jeweler for a professional measurement. It is a simple step that can make your custom ring feel more comfortable and secure for years to come.
Frequently Asked Questions
What ring size system does Viramia use?
Viramia uses US ring sizes as the main sizing standard.
What if I am between two ring sizes?
If you are between sizes, the larger size is often more comfortable, especially for wider bands. For slim bands, your usual size may still fit well.
Can I measure my ring size at home?
Yes. You can measure either the inside diameter of a ring you already own or the circumference of your finger. For the most accurate result, measure more than once and compare your result with the chart.
Are international size conversions exact?
No. International size conversions are approximate. Millimeter measurements are usually the most helpful reference.
Should I size up for a wide band?
If the band is wide or you are between sizes, sizing up may feel more comfortable.
How tight should a ring feel?
A ring should feel secure but comfortable. It should slide over your knuckle with gentle resistance and should not pinch, leave deep marks, or feel difficult to remove.
