Patio Mortar Calculator

Welcome to our patio mortar materials calculator. Please use it to estimate the amount of sand and cement required to complete your project


  • Measure the length and the width of the area. Measure in metres and part metres. For example, 10 feet would be 3.05 metres. If the area is irregular, break the calculation down into a series of smaller rectangles and add together.
  • Enter the height and width dimensions in to our easy calculator. You may be surprised as the results are often more than you think.
  • Our standard Maxi bags of sand are a minimum of 850 kgs.

If what you need does not match closely to the Maxi bags don’t panic. We can supply pretty much any weight in another format either in half bags, loose or Maxi bags with 25kg bags to “top up”.

For non-standard bags, please call 01935 822204 and ask for the Trade Counter.

If in doubt, please call and we will be happy to help you work out your requirements.
