How to Choose the Right Tin Size: A Factory Insider’s Guide for Candles, Creams, and Tea
Choosing the wrong dimensions for your custom tin isn't just a design mistake—it's a logistics nightmare. If the tin is too big, your product looks small and you pay too much for shipping air. If it’s too small, it won't fit your filling machinery.
At Tinboxmate, we help brands navigate the maze of millimeters and ounces. Based on thousands of production runs, here is how we recommend picking the perfect size for your specific industry.
Candle Tins: Balancing Burn Time and Heat
For the candle industry, "standard" usually means 2oz, 4oz, and 8oz sizes. But there is more to it than volume.
The 2oz Travel Tin: Best for "sample sets" or wedding favors. These usually have a diameter of around 50mm.
The 4oz Tin: Our most popular size. It’s the sweet spot for retail price points.
The 8oz Tin: Ideal for luxury scents with longer burn times.
Pro tip from our engineers: Always consider the "wick clearance." A tin that is too narrow will get too hot, while one that is too wide may not allow the wax to melt evenly to the edges.
Cosmetic Creams: Focus on Portability and Sealing
When it comes to creams, salves, and balms, the focus shifts to height. A shallow tin (around 15mm to 20mm high) is much easier for a customer to use because they can reach the bottom easily with their fingers.
For 10g to 50g capacities, we suggest looking at our existing mold library first. Why? Because using a "standard" diameter like 40mm or 60mm can save you thousands in tooling costs. We can usually adjust the height of our existing molds to change the volume without you needing to pay for a new base mold.
Tea Tins: It’s About Volume, Not Weight
This is where most buyers get confused. 100g of dense Black Tea takes up much less space than 100g of fluffy White Tea.
We always ask our tea clients to send us a sample of their actual product. We then perform a "fill test" to determine the exact dimensions needed. For a typical 100g tea retail pack, a tin roughly 80mm in diameter and 120mm in height is the industry go-to, but we can customize this to make your brand stand out on a crowded shelf.
Save Money by Designing Around the Sheet
As a factory, we look at how many tins we can cut from a single sheet of tinplate. Sometimes, changing your tin's diameter by just 2mm can reduce material waste by 10%, directly lowering your unit price.https://tinboxmate.com/about-tinboxmate/
