Ring Size Guide
How to Find the Right Ring Size at Home
Finding your exact size is important for not just comfort but also security and durability. You can find your ring size through home measurements when you use these three basic techniques.
The methods in this section provide effective ways to determine your ring size, which should be done before you order your ring.
Method 1: Measure an Existing Ring

(Recommended if you already own a well-fitting ring)
How it works:
You need to put a ring which fits you well onto a flat surface and use a ruler or calliper to measure its inner diameter. The measurement should be compared with a standard ring size chart to determine your appropriate size.
Method 2: String or Paper Method

(Simple and accessible)
How it works:
Wrap a thin strip of paper or string around the base of your finger. Mark where it overlaps, then measure the length with a ruler. Use a size chart to convert the measurement to your ring size.
You should measure at room temperature because measuring with cold fingers or swollen fingers needs to be avoided.
Method 3: Printable Ring Size Chart

(Most accurate at home)
Download and print a ring size guide, ensuring the scale is set to 100%. Place your ring over the printed circles to identify the best match.
Method 4: Professional Measurement

(Best for complete accuracy)
The most precise method exists in professional ring measurement, which people should obtain from local jewelers. The professional fitting process allows you to assess ring comfort and ring fit, which helps you determine whether the ring correctly fits your finger.
The ring size measurement service at our store lets you confirm your ring size before making a purchase. The method helps you decide between two sizes and select a larger band size.

What should I do if I'm between ring sizes?
If you find yourself between sizes, we usually recommend choosing the slightly larger size. Fingers can swell a little in warm weather, so this gives a bit more comfort and flexibility.
Does resizing weaken the ring?
Resizing involves carefully adding or removing a small amount of precious metal to adjust the size. While resizing a ring too many sizes up or down can affect its strength, we always work within safe resizing limits.
At Rings of UK, any resizing is carried out with great care to maintain the ring's integrity. Every resized ring is also cleaned and polished before it's returned to you, so it looks as beautiful as when you first received it.
What is the most common engagement ring size?
The most common ring sizes typically fall between K and P. If your measured size is outside this range, we recommend double-checking your size using another method or our printable guide, as most rings can only be resized by a limited amount.
