How to Create a Sizing Chart for Your Fashion Brand

Creating a sizing chart is a crucial step in fashion product development, serving as an essential guide for designers and brands to ensure consistency and accuracy of sizing. In this blog post, I'll explain why a sizing chart is essential and how you can create an effective one for your brand.

Why your fashion brand needs a sizing chart

1. ‍Helping customers understand what to buy : Asize chart enables your customers to make informed choices, which increases customer loyalty, improves shopify experiences and reduces returns and customer service requests.‍
2. Create consistent sizing across your collection : A well-designed sizing chart ensures consistent sizing across your brand's different styles, facilitating style development and reducing the time and costs associated with prototypes and fittings.‍
3. Define your customer's unique body type : A size chart helps you target your market by defining the specific body type your garments are aimed at, enabling you to tailor your designs and marketing strategies to better meet your customers' needs and preferences.

Sizing chart types: Internal vs. External

• External (Public) : Used to educate customers about your brand's specific sizes, often displayed on retail sites.
• Internal (Private) : Used for garment development and maintaining consistent sizing across your brand's different styles.

How to Create a Sizing Chart

1. ‍Identify your customer and their body type : Define the profile of your ideal customer, taking into account factors such as age, gender, size, shape, tone and nationality.‍
2. Research and source size information : Compile size data that relates directly to your target customer's unique body type.‍
3. Compare and analyze data : Use a comparison template, such as an Excel spreadsheet, to facilitate the comparison process and gain accurate insights into your target market's sizes.‍
4. Make decisions : Make informed choices about how the data collected applies to your ideal customer's body type.‍
5. Finalize your chart : Create a clear, visually appealing chart that identifies where each measurement is taken and includes each size in your range.

Best Practices for a Successful Sizing Chart

1. ‍Body measurements vs. garment measurements : Your sizing chart should be based on body measurements, not garment measurements.‍
2. Single measurement vs. range : Each measurement on the sizing chart means "up to". So it's common to use a single number for each size.
   

By using these guidelines and regularly updating your size chart, you can ensure that your garments fit well and meet your customers' expectations, while simplifying the product development process for your brand.
