Ring Buying for Men: The Tape Measure Method & Size Chart

In short: First off: buying a ring for men: the measuring tape method & size chart. Buying a ring without knowing the ring size is risky. Especially for men who rarely wear rings, measuring is a challenge. The size is the only real risk with a ring, everything else can be clarified beforehand. Those who wear it daily benefit most from narrow bands and rounded inner edges.

Measuring ring size for men: All methods explained

Method 1: Have it measured by a jeweler

The most precise method. A ring sizing set contains sample rings in all sizes, simply try them on, found the right size. Free at any jeweler. Always recommended for important purchases (wedding ring, expensive ring).

Method 2: Measure the inner diameter

Place a suitable ring on white paper, measure the inner diameter (ruler or caliper). Compare with size chart:

• Diameter 15.7 mm = Size 49
• Diameter 16.5 mm = Size 52
• Diameter 17.3 mm = Size 54
• Diameter 18.2 mm = Size 57
• Diameter 19.1 mm = Size 60
• Diameter 20.0 mm = Size 63

Method 3: Measuring tape/string method

Wrap string or a narrow strip of paper around the finger, mark the circumference, measure the length. Divide by π (3.14159) = diameter. Then use the chart.

Which important notes apply to men?

• Measure in the morning, fingers are then slightly smaller than in the evening
• Dominant hand often has larger fingers, for which hand is the ring bought?
• Wide rings (over 8 mm) fit tighter than slim ones, choose 0.5 to 1 size larger
• In summer fingers are slightly thicker than in winter

What if the size is not correct?

Solid gold rings can be adjusted by 1 to 2 sizes in most cases. Ask about the adjustment option at the time of purchase.

What goes well with rings?

A harmonious look is created by gradation, not by as many pieces as possible. Rose gold combines well with yellow gold, with silver on the other hand only through a bicolores link. Two well-coordinated pieces look more thoughtful than five random ones.

When does wearing the rings cause damage?

The clasp is almost always the component that gives way first, and it is most heavily stressed at certain moments. Sauna and heat do not damage the material, but they accelerate the abrasion on coated parts. The rest of the day, including shower and rain, is not an issue with stainless steel.

Which details reveal the workmanship of rings?

Between two visually identical pieces, the difference is almost always in the workmanship, not in the material. Important are clean edges without sharp points, even surfaces and a clasp without play. This is not an expert test, but the minimum check before every purchase.

What goes wrong most often when buying rings?

With rings, a wrong choice rarely costs a lot of money, but it repeats itself if the cause remains unclear. The classic is a piece that fits an occasion that happens twice a year. The 14-day return covers the rest, but the better decision is made beforehand.

How much do good rings cost and what do you get for it?

The entry begins in the low double-digit range, upwards the range is open. Sterling silver starts at about thirty euros, solid gold only in the triple-digit range, in between lies the entire fashion jewelry market. Who is looking for substance for decades, ends up with solid gold and a different price level.

How do you properly care for rings?

With rings, the visible loss of shine is usually caused by deposits, not by wear. Silver polishing cloths belong to silver, not to coated stainless steel, there they wear off the layer. What cannot be removed this way is usually abrasion and not dirt.

Material, dimensions and prices at a glance

Showering, swimming and sports do nothing to the stainless steel, it does not tarnish. For the selection of a ring, these values from the Corelune range help.

Frequently asked questions

What ring size do I have?

Measure the finger circumference in the evening with a strip of paper, because fingers swell slightly during the day. The circumference in millimeters corresponds to the German ring size.

What do I do if the ring does not fit?

With stainless steel, there is no practical size adjustment. Therefore, the way via the 14-day return is the easier.

Does ring stacking work in everyday life?

Yes, it works well with two to three narrow rings on one finger, while the other hand remains simple. Everything else quickly becomes restless.

Are rings with stones suitable for everyday wear?

Conditionally. Set stones last significantly longer than glued ones, and the flatter the stone sits, the less it catches. Check the setting occasionally with a fingernail: If the stone moves, you should take off the ring for sports and housework.

Examples that apply to this: Ring Heart from stainless steel, Mini and Statement Ring Shell with Shell from stainless steel. You can find more rings in the category Rings.
