Bangle Personalizer for Custom Jewelry: Sizes, Sets and Engraving on Shopify

How bangle sizes work

Indian bangle sizes look like decimals but they are not. A 2.4 bangle is 2 and 4/16 inches across the inside, which is 2.25 inches. A 2.6 is 2 and 6/16 inches. The number after the point counts sixteenths of an inch, so 2.10 and 2.12 are bigger than 2.8, not smaller.

That catches out customers outside India and even some within it. Show the inner diameter next to every size.

Measurements follow published Indian size charts. Your own maker may vary by a millimetre, so check against your stock.

Kadas are broader and heavier than bangles and are usually worn alone, so they tend to be sized larger and fit looser. If you sell both, give them separate size lists. "Free size" bangles with an opening or clasp should say so plainly and skip the size field.

Help text that stops wrong sizes

Most customers outside India think in wrist size, and wrist size does not help with a bangle. The bangle has to pass over the knuckles.

Put two methods under the size dropdown:

1. Use a bangle you own. Lay it on a ruler and measure the inside edge to inside edge in millimetres. Match it to the chart.
2. Measure your hand. Bring your thumb and little finger together, wrap a string or tape around the widest part of the hand, and divide the length by 3.14. That gives the inner diameter you need.

Then add one plain line: "Between sizes? Choose the larger one." A slightly loose bangle gets worn. A tight one comes back.

For girls' bangles, sizes around 2.2 to 2.4 cover many children aged 7 to 12, but adjustable styles are the safer choice for kids whose hands are still growing.

Selling bangles as sets

In India bangles are often bought in pairs or sets, for weddings, festivals and gifts. That changes how your personalizer should be built.

• Ask for size once. A set of four bangles goes on the same wrist, so one size dropdown covers the whole set. Do not make the customer pick it four times.
• Let the set size drive the price. A dropdown with "Pair", "Set of 4" and "Set of 6", each with its own price, is clearer than four separate products.
• Decide which bangles get engraved. Most customers want text on one or two bangles in a set, not all of them. Offer "Engrave 1 bangle" and "Engrave 2 bangles" with separate fees.
• Use conditional logic for the second name. For a couple's pair, show a second text field only when "Engrave 2 bangles" is chosen, so each partner's name has its own line.

Mixed metal sets (two gold tone, two silver tone) work well as image swatches. Show a photo of each finished set, not a flat color dot.

Engraving on a narrow band

Bangles are narrow and curved. A band 3 to 6 mm wide has room for one line of short text, and the curve makes long text harder to read because it wraps out of view.

What works:

• Inside engraving for private messages: "Aarav 14.02.2026" or "Ma" or a pair of initials.
• Outside engraving for names in a script that becomes part of the design. Keep it short.
• Character limits by width. As a starting point, try about 12 characters on the outside of a thin band and about 20 on the inside, then test on your own blanks and adjust.
• One font for numbers. Scripts look lovely on a name and turn a date into a squiggle at that height. Offer a clean serif or sans-serif for dates.

For Indian customers, ask whether you can engrave in Devanagari or other scripts before you offer it. Only list fonts your engraver can actually cut cleanly at bangle scale, and make sure the live preview uses the same font so what they see is what they get.

Gold and silver bangles in India

Gold bangles sold in India must carry a BIS hallmark. Hallmarking is mandatory for gold jewelry, and the Indian standard allows six gold grades: 14, 18, 20, 22, 23 and 24 carat.

Two practical points for your personalizer:

• Keep the hallmark clear. The hallmark is struck at a BIS-recognised assaying and hallmarking centre, not by you. Check where it sits on your bangles and position the inside engraving so it does not overlap.
• Price the engraving separately from the metal. Gold jewelry in India is usually priced by weight plus making charges, and the gold rate moves daily. Keep your product price for the metal and add engraving as its own fee, so you can update one without touching the other.

Silver bangles have their own hallmarking standard in India. Lighter, cheaper and easier to engrave, silver is a good place to start if you are testing personalized bangles for the first time.

Pricing bangle personalization

A simple structure that customers understand:

These are suggestions at the time of writing (October 2026). Base yours on actual engraving time per piece. PIMW shows every fee as a separate cart line, so the customer sees "Engraving, 2 bangles" next to the set price.

How to set up a bangle personalizer in PIMW

Your first personalized bangle can be live in about 15 minutes, and the free plan covers your first product.

1. Install PIMW Product Personalizer and add the app block to your product template in the theme editor.
2. Create an option set called "Bangle set".
3. Add a set size dropdown with a price on each choice.
4. Add the bangle size dropdown with inner diameters in each label, for example "2.6 (60 mm)", and the measuring help text.
5. Add an "Engrave how many" dropdown with its fees.
6. Add the first name field with its character limit and fonts, and position it on the bangle in your product photo so the live preview sits on the band.
7. Add the second name field and set it to show only when "2 bangles" is chosen. Conditional logic starts on the Pro plan.
8. Place a test order and check that size, set, text and font all appear as line-item properties on the order.

Common mistakes with bangle personalizers

• Treating 2.10 as smaller than 2.8. Sort your size list by actual diameter, not by how the number looks.
• Asking for wrist size. Bangles go over the hand. Ask for hand measurement or an existing bangle.
• Size picked per bangle in a set. One wrist, one size. Ask once.
• Long text on a curved band. Half of it wraps out of view. Keep limits tight and let the preview prove it.
• Engraving over the hallmark. Plan the inside layout around it.
• Mixing metal price and engraving fee. When the gold rate moves you should not have to rebuild your options.
