SUPPORT
Thanks for using it.
MeasurePatch is a side project. I built it because working out how much gravel to order shouldn't take a spreadsheet and three browser tabs. It's free, there are no ads, nothing tracks you — and that stays true whether or not anyone ever chips in.
If a calculator here saved you a second trip to the supplier, you're very welcome to buy me a coffee. No pressure either way, and the site works exactly the same if you don't.
Any amount, one-off or monthly. Buy Me a Coffee handles the payment — you'll leave this site to do it.
Where it goes
The domain, and the hours that go into keeping the numbers right. Hosting is free at this size, so that's genuinely the whole list — nobody's getting rich here.
Everything stays free
Nothing on this site is locked behind a payment, and nothing will be. There's no supporter tier, no ad-free upgrade and no early access, because the free version is already the whole thing. Chipping in also won't get a product listed or a brand mentioned — the calculators stay supplier-neutral.
Rather help for free?
Honestly, the most valuable thing you can send costs nothing. If a calculator gives you a result that looks wrong, please tell me — the contact page explains what to include, and a good bug report is worth more to this site than the money.
After that: mention it to someone who measures things for a living. That's how small tools like this find the people who need them.
