Converting Asian Size to US Size: FAQs

Understand the Differences Between Asian and US Size

A commonly encountered challenge for shoppers dealing with global fashion is to convert Asian size to US size. The main thing to remember here is that Asian sizes are much smaller than US sizes — normally one or two complete sizes less. For example, an extra small in the US could turn out to be a small or medium in Asian countries.

This is because Asian sizing caters to smaller frame sizes. So, the measurements of the average body size are likely to differ. Plus, there’s no standardization across Asian countries, so sizing can vary by brand. If you’re sourcing from multiple dropshipping clothing suppliers, this inconsistency can be frustrating for your customers — especially when they can’t try on the clothing before buying.

Therefore, it is crucial to check a brand specific sizing chart and read customer reviews to get the best fit. Generally, it’s safe to err on the side of sizing up, but it doesn’t hurt to double check to prevent mistakes.

The Importance of Size Conversion for Online Store

For online retailers, giving accurate size conversion charts is not only convenient. It’s an important part of offering a seamless shopping experience. Incorrect sizing is one of the leading causes of online return. Customers who don’t get items that fit raise return costs for the business. Streamlining clear Asian sizes to US conversions can significantly reduce returns and improves overall customer satisfaction.

International customers want size conversion tools and info, which help boost your level of trust. Many people are hesitant to buy wholesale clothing from Asia only because you never know if it’s going to fit. However, when stores have reliable conversion charts and detailed measurements, customers can shop with confidence. It also builds a good reputation as positive reviews line up.

Moreover, displaying an accurate Asian size to US comparison helps make your store more accessible around the world. This tells that your brand appreciates and understands your international customers. In increasingly competitive e-commerce, that kind of customer first approach can give a store an edge. In other words, good size conversion just makes sense: it spurs business and adds to real customer satisfaction, and thus to build loyal customers.

How to Convert Asian Size to US Size with Accuracy

For any e-commerce business targeting a global audience, the step of understanding how to convert Asian sizes to US sizes is critical. Asian sizing lacks standardization, so a clear approach is needed to ensure customer satisfaction and reduce returns. Here are some strategies for accurate size conversions below:

1. Ask Your Suppliers for Conversion Charts

Start by asking your suppliers — whether you’re working with USA clothing dropshipping suppliers or Asian ones — to send you detailed size conversion charts. Measurements in centimeters and inches should also be included in these charts for the key dimensions: chest, waist, hips, and inseam. With supplier provided data, you know that you’re working with the accurate information for the garments you are selling. This is a foundational step for effectively translating the Asian sizes to US sizes.

2. Always Check Brand-Specific Size Charts

While brands in the same country are usually similar, the sizing can still vary big time. It is always preferable to consult the brand’s size chart instead of only using generic conversion tables. Each of these charts offers exact measurements according to the brand’s specific sizing standards to inform customers and reduce the chances of returns.

3. Create Size Charts for Each Product Type

The sizing needs differ for shirts, pants, and shoes other items. This makes it important to develop individual size charts for each product type. Your size charts must be tailored to specific products to better fit the items and ensure your customers can select the correct size with clarity.

4. Factor in Fabric Stretch and Garment Style

The fit of a garment is greatly dependent on its material. For example, spandex is stretchy fabric, which can be more flexible. On the contrary, you need fine-tuned sizing for hard materials like denim. You should also think over the style of the garment (slim-fit, regular, or oversized) in regards to how clothing will drape on the body. Fabric and style information helps customers get a sense of fit and choose sizes.

6. Encourage Customers to Take Their Own Measurements

Encourage your customers to measure their size accurately by giving them straightforward instructions. Go the extra mile by providing detailed guides or videos demonstrating how to measure areas such as chest, waist, hips, and inseam. Self-measurement on customers’ part guarantees correct comparison with your size charts and the better fit selection.

5. Include Customer Reviews About Sizing

Customer reviews are a useful way to get an idea of how a garment will fit in your specific real world scenario. Ask your buyers to share their measurements, sizes they bought, and fit & comfort feedback. Such user generated content can double as practical reference for potential customers.

7. Consider Using a Size Calculator or Recommendation Tools

Provide size calculators or recommendation tools like MP Size Chart & Size Guide for customers on your website. These tools take measurements supplied by the customer and will recommend the correct size based on the specifications of your product. Such technology implements enhanced the shopping experience through personalized size recommendations, decreasing uncertainty and potential returns.

8. Don’t Overlook Supplier’s Return Policies

Make sure you know your supplier’s return and exchange policies. Also ensure that these policies are clearly communicated to your customers. Remember, customers trust transparent return policies!
