Ever had a customer ask, “Will this fit me?” right before checkout? Or tried converting a US size to UK or EU sizing and ended up more confused?

The free Clothing Size Chart Generator & Size Converter by 6Six Needles makes apparel sizing a whole lot easier.

Whether you’re launching a streetwear brand, running a Shopify store, selling on Etsy, or shopping internationally, you can create professional clothing size charts and compare international sizes in one convenient place.

Create clothing size charts your customers can actually understand.

Switch between inches and centimeters, then download your finished chart as a PNG, PDF, or CSV. You can also copy the table or HTML directly into compatible product pages.
