Estimates are for planning

Buildzly calculators give estimates based on the measurements you enter and published product figures. Real projects vary with site conditions, products, local prices and workmanship. Check quantities against product labels, and buy a small surplus where running short would be costly.

Not professional advice

Nothing on this site is engineering, legal or contractor advice. For structural work or anything that needs a permit, follow your local building code and consult a qualified professional.

No warranty

The site is provided "as is". We work hard to keep it accurate, but we can't guarantee every result is error-free, and we are not liable for losses from using it.
