Built around one practical question
How much gravel should you order? We help turn dimensions into volume, estimated weight and bags. Every estimate shows its density and allowance so you can discuss the result with a supplier.
Who maintains this tool
Site Measure is an independent project. Meet the maintainer on LinkedIn, or send questions and corrections to support@site-measure.com.
What we do
We publish the calculation method, use explicit unit labels and let you replace the general density with your own product specification. Calculations happen in your browser. You do not need an account.
How calculations are checked
Our verification notes describe the software checks and their limits. Published material references link to their source. No independent engineering review is claimed.
What to check before ordering
We do not sell gravel or supply installation specifications. Your supplier or installer should confirm the material, depth, compaction requirements and purchase increments.
