How many ring sizes should a first collection stock?

ZKZ Editorial TeamMain answer · Product & gemmology desk

Do not order every size in equal numbers. Build the size run around your market's most common sizes, put the biggest share of quantity there, keep outer sizes small or made to order, and agree resizing rules with the factory before you pay. Use your own customer data when you have it, and a sensible spread when you do not.

Start with your market, not with the factory

Uncertain There is no single "standard" size distribution, because it differs by country, age group and style. We do not give percentages, since any figure we gave would be a guess. Check your own sales or enquiries, ask a few retailers in your market, and compare the size chart your customers use (US, UK, EU or millimetres).

Our advice As a rule, quantities should rise toward the middle of your market's range and fall away at both ends. Order the full range only for your best-selling styles.

A practical way to plan

1. Pick your range. List the smallest and largest sizes you want to sell, and whether you will offer half sizes. Adding half sizes multiplies the number of variants, so start with whole sizes on all styles and half sizes only on bestsellers.
2. Split by style. Plain bands and solitaires, which are easier to resize, can be stocked in fewer sizes. Rings with stones all the way around, wide bands or complex shapes are hard to resize, so those need a fuller size run.
3. Decide on made-to-order. Offer unusual sizes as made-to-order with a lead time, instead of holding stock of them.
4. Agree the factory rules. Ask for the minimum order per style and per size, the cost and time to resize or remake, and the tolerance on size accuracy.
5. Mark the size. Ask whether the size is stamped inside the band and whether the stamp matches the chart you use.

Reduce risk

• Start with fewer styles in more sizes instead of many styles in few sizes, so you can learn which sizes sell.
• Keep a small number of sample rings in common sizes for photographs and fit checks.
• Record every sale and return by size, then use that data for the second order.

Fact Silver can be resized, but each resize involves heat and removes or adds metal, and plating may need to be redone afterwards. Ask the factory what resizing does to plating and stones.

It depends How many sizes you should stock depends on the budget, the style mix and how quickly you can reorder. A brand with fast reorders can hold fewer sizes than one with long lead times.
