How to Measure Your Ring Size

Finding your perfect ring size is essential for comfort and security. THOMAS SABO offers two simple methods to measure your ring size accurately at home in just a few minutes.

Method 1: Measure an Existing Ring

If you already own a ring that fits well on the intended finger, this is the easiest method:

1. Select a ring that fits comfortably on the finger you plan to wear your new THOMAS SABO ring.

2. Place the ring on a flat surface.

3. Use a ruler to measure the inner diameter of the ring in millimetres (mm).

4. Be precise - measure from the inside edge to the inside edge.

5. Match your measurement to our size chart below to find your THOMAS SABO size.

Pro tip: For the most accurate measurement, use a ruler with millimetre markings and measure at the widest point of the ring's inner circle.

Method 2: Use the Paper Strip Method

Don't have a ring to measure? No problem! This method works perfectly:

1. Cut a strip of paper approximately 10cm long and 5mm wide.

2. Wrap the paper strip snugly around the base of your finger (where the ring will sit).

3. The paper should be comfortable - not too tight, not too loose.

4. Mark with a pen where the paper overlaps.

5. Remove the paper and lay it flat.

6. Measure the length from the end to your mark in millimetres.

7. This measurement is your ring circumference - match it to our chart. THOMAS SABO specifies the ring sizes by the inner circumference of the ring in millimetre (mm). For example size 44 corresponds to 44 mm.

Alternative: You can also use a piece of string instead of paper. Just ensure it doesn't stretch when you're measuring.

To measure, wrap the strip of paper around the desired ring finger, marking the ends with a pen. 

 

Measure the marked strip of paper with a ruler to determine your ring size in mm.

Expert Tips for Accurate Ring Sizing

Measure at Different Times of Day

Your finger size naturally fluctuates throughout the day due to temperature, activity level, and hydration. For the most reliable result:

1. Measure your finger in the evening when fingers are typically at their largest.

2. Avoid measuring immediately after exercise or when your hands are very cold.

3. Take measurements on 3-4 different days and use the average.

4. Consider seasonal changes - fingers tend to be larger in summer.

When in Doubt, Size Up

A ring that's slightly too large is always preferable to one that's too tight. Here's why:

1. Ensures comfort throughout the day as fingers naturally swell.

2. Prevents the ring from getting stuck on your finger.

3. Easier to add a ring guard to make it smaller than to stretch a ring.

4. Allows for natural finger size changes over time.

Consider Ring Width

The width of your ring affects how it fits:

1. Narrow bands (2-4mm): Usually fit true to size.

2. Wide bands (6mm+): May require going up half a size for comfort.

3. Comfort fit bands: Have a curved interior and may fit differently than traditional flat bands.

Account for Knuckle Size

1. Measure both your knuckle and the base of your finger.

2. Choose a size between the two measurements.

3. Consider rings with sizing beads or a hinged shank for the perfect fit.

How to Find Someone's Ring Size Secretly

Planning a surprise proposal or gift? Here are clever ways to discover their ring size without spoiling the surprise:

Method 1: Borrow an Existing Ring

If they already wear rings, borrow one that fits the intended finger and measure the inner diameter. This can provide a close estimate.

Method 2: The Friend Conspiracy

Enlist the help of their close friends or family members who can:

1. Casually bring up ring sizes in conversation.

2. Suggest trying on rings "for fun" during a shopping trip.

3. Already know their size from previous jewellery gifts.

Method 3: The Clay Impression

1. Press one of their rings into a bar of soap or clay.

2. Take the impression to a jeweller for sizing.

3. This preserves an exact imprint without removing the ring.

Method 4: While They Sleep

1. Gently tie a piece of string around their finger while sleeping.

2. Mark where it meets and measure later.

3. Only recommended for heavy sleepers!

Common Ring Sizing Mistakes to Avoid

1. Measuring with the Wrong Tools

Always use non-stretch materials like paper or string.

2. Measuring at the Wrong Temperature

Ensure hands are at normal room temperature.

3. Pulling Too Tight

The material should slide over your knuckle with slight resistance.

4. Guessing Based on Appearance

Always measure - ring size doesn't correlate with other body measurements.

When is the best time to measure ring size?

The best time to measure your ring size is in the evening when your fingers are at their largest. Avoid measuring when your hands are cold or immediately after exercise. For the most accurate result, measure 3-4 times on different days and use the average.

Can THOMAS SABO rings be resized?

Unfortunately our THOMAS SABO rings cannot be resized.

What if I'm between sizes?

If your measurement falls between two sizes, we recommend choosing the larger size. This ensures comfort throughout the day and accounts for natural finger swelling. You can always use a ring guard for a more snug fit if needed.

Do different fingers require different sizes?

Yes! Each finger can be a different size, even on the same hand. Your dominant hand is often slightly larger. Always measure the specific finger where you plan to wear the ring.

How do I care for my THOMAS SABO ring?

To maintain your ring's beauty:

1. Remove rings before swimming, exercising, or cleaning.

2. Store separately to prevent scratching.

3. Clean regularly with a polishing cloth.

4. Have your ring professionally cleaned and checked annually.
