White label and custom size tooling
Everything free on MySizeCharts stays free, in full, forever. This page is about the handful of things a company needs and a shopper never touches, which is the only honest thing to charge for.
What you can pay for
- A white-label widget.The same converter without the "Sizes by MySizeCharts" link, and with your own logo if you want one. This is the natural upgrade and the one most people ask about.
- Your own measurements inside it.The free widget carries the neutral tables. A paid one can show your brand's measurements next to the neutral conversion, which is what a shopper actually needs when your fit differs from the standard.
- A hosted API on your own subdomain. Same data, your domain, with an availability commitment in writing. The public API stays exactly as it is: free, unmetered, no key.
- A commercial data licence. The JSON stays free under CC BY 4.0, which requires attribution. If attribution does not work for your use, what you are buying is the licence and the support, not access to the data.
- A converter built into your product page. Not an iframe: the real thing, in your template, using your stock and your size tables. That is FusionStudios work rather than a product.
What is not for sale, at any price
- Access to a chart. Every chart is free and complete.
- Removing advertisements. There are none.
- A "pro" converter with more systems in it. Every system stays in the free one.
- A place in a chart. No number moves for commercial reasons. See the affiliate disclosure.

Common questions
Will anything that is free today move behind a paywall?
No. Every chart, every converter, the printable pages, the JSON API and the embeddable widget stay free and complete. What is on this page is work that a company needs and a shopper never touches. If that promise is ever broken, the changelog will carry the date it happened.
Why are there no prices?
Because we would be inventing them. Every item here is scoped work whose cost depends on what you already have. Describe the situation and you get a real number rather than a made-up one anchored to a pricing page.
Do I need any of this to use the widget commercially?
No. The free widget is licensed for commercial use as it stands. The only paid version of it is the one without the attribution link.
