Before you contact us
A few quick answers that solve most questions faster than waiting on a reply:
A calculator gave a result I didn’t expect
Double-check your units (feet vs inches vs mm) and whether you entered nominal or actual dimensions. Most surprises come from a units mix-up. If the number still looks wrong, send us the exact inputs you used and we’ll check the math.
Can you add a calculator for ___?
Yes, tell us what you need. We build tools based on what people actually ask for, so suggestions genuinely shape what comes next.
Are the results safe to build from?
Our calculators give accurate material estimates for planning and ordering, but they don’t replace an engineer or your local building code. For structural or permitted work, always confirm with a professional.
Can I use your calculators on my own site?
Get in touch and tell us what you have in mind. We’re happy to talk through it.
