Email is the only way to reach us, and every message goes to the same inbox.
Email us
That button opens your email program with a short template already filled in. Nothing is sent until you send it.
There is no contact form on this site. A form would need a server to receive it, and this site does not have one, so a form here would look functional while quietly going nowhere.
What to include
If you are reporting a result you believe is wrong, the report is only actionable with the inputs. Please tell us which calculator, whether you were in metric or imperial, exactly what you typed including the unit shown next to each box, the result on screen and the result you expected. A shareable link from the results panel captures most of this in one go.
What we can help with
- Suspected errors in a calculation, conversion or rounding rule.
- Unclear wording in a guide or on a calculator page.
- Accessibility problems, including anything that does not work by keyboard.
- Suggestions for a shape or option the calculators do not currently handle.
What we cannot help with
We cannot advise on slab thickness, footing depth, reinforcement, mix specification or whether a particular design is adequate. Those decisions depend on loads, ground conditions, climate and local rules, and they belong with a qualified professional or your local building authority.
Response times and the contact address
This is a small independent project, so responses may take a few working days. For all enquiries, email contact@materialmeasures.com.
Privacy
If you email us we will see your address and whatever you write. We use it to reply and for nothing else, we do not add it to a mailing list, and we do not pass it on. Your calculator inputs are never transmitted to us unless you paste them into a message yourself.
