Support SizeDecoder

SizeDecoder is free to use and ad-light by design. If the size charts, conversions, or tools saved you a return or a bad guess, a small one-time contribution helps keep the data current and the tools free for everyone else.

What a contribution actually pays for

This isn't a large operation with staff or an office — it's a small, independently run reference site. The real, recurring costs are hosting, the time spent rechecking size tables against updated brand and regional standards so a chart from three years ago doesn't quietly go stale, and responding to the reports that come in through the contact page when someone flags a conversion that doesn't match a real product. A tip doesn't buy anything flashy; it buys the time to keep doing the unglamorous maintenance work that keeps the numbers trustworthy.

Why donations instead of a paywall

Every conversion, chart, measuring guide, and tool on this site stays free and accessible without an account, a login, or a subscription — that's a deliberate choice, not a temporary state before a future paywall. A size conversion is exactly the kind of quick, practical lookup that shouldn't require handing over payment details first. Donations exist as an optional way for people who found the free tools genuinely useful to support keeping them that way, not as a workaround for content that's secretly meant to be paid.

If you want something tangible in return

A donation here is a tip with nothing shipped back — if you'd rather receive a real product for your money, the Perfect-Fit Measurement Kit is a $9.99 printable measuring kit: a verified-scale paper tape, step-by-step worksheets for every garment type this site covers, and a personal size-record card for each member of your household. Buying that is a way to support the site while getting something genuinely useful for your own next order, rather than a pure tip.

Other ways to help that cost nothing

If a donation isn't the right fit right now, two things help just as much in practice: using the contact page to flag a size chart that doesn't match a real product you own, and linking to a specific conversion or chart page when it genuinely answers a question you searched for. Accurate, current size data depends partly on people who actually use the numbers on a real order telling us when something's off — that feedback loop keeps the whole site honest in a way a one-time payment can't.

Where a contribution goes, in practice

Contributions are processed through Stripe and go toward the same running costs described above — hosting, data maintenance, and time spent on chart corrections. There is no separate donation fund report published, since this is a single small site rather than a registered nonprofit; treat a contribution as a direct thank-you for the specific tools and charts you used, not as a donation to a formal cause.
