About EnoughCalc

Every home project starts with the same question: how much do I need to buy? Buy too little and you make a second trip mid-job. Buy too much and the leftovers sit in the garage. EnoughCalc answers that question in the units you actually buy — bags, boxes, tins and tonnes.

What makes our calculators different

  • Retail units, not just volumes. We convert cubic metres and cubic yards into bags and boxes.
  • Metric and imperial. Every calculator works in both, so it's useful in the US, UK, Canada, Australia and beyond.
  • Sources for every figure. Material weights, bag yields and coverage rates come from manufacturers and industry references, listed on How we calculate.
  • Tested maths. Each formula is checked by automated tests against known answers before it goes live.
  • Private by design. Your measurements are calculated in your own browser and never sent to us.

Who runs EnoughCalc

Hi, I'm Elijah, and I run EnoughCalc.

I started it because I got tired of buying the wrong amount for home projects. Buy too little and you're back at the store halfway through the job. Buy too much and the leftover bags sit in the corner for months.

Whether you're laying a driveway, putting up a fence, painting a room or filling a raised bed, the first question is always the same: how much do I actually need? EnoughCalc answers it in the things you buy: bags, boxes, tins and bulk loads.

I check the numbers behind each calculator against manufacturer data sheets and supplier information, and the sources are listed on every page so you can check them too.

That's the whole idea behind the name: buy enough, not too much.

Thanks for stopping by. I hope it makes your next project a little easier.

We are not a store and we don't sell building materials. If you spot an error or want a calculator we don't have yet, please get in touch — corrections are fixed quickly and noted on the page.
