About Hat Size

Hat Size was built for the moment you just need to handle this task and move on — no signup, no upload to a third-party server. Built to be the kind of tool you bookmark and use weekly: no surprises between visits, no degraded free tier, and a UI that gets out of the way. If you find yourself doing this regularly, the rest of the utility suite covers most adjacent tasks with the same approach.
