Compost & Bark Mulch Calculator

Find out exactly how much compost, bark, or topsoil you need for your flower beds with this easy UK garden calculator. Just enter your bed size and depth, and it tells you the total volume, weight, and number of bags required.

Flower Bed Projects

If you’ve ever started a flower bed project and found yourself halfway through with one sad bag of compost left, this tool is your new best mate. The Compost & Bark Mulch Calculator takes the guesswork out of gardening by working out precisely how much material you need before you even get your hands dirty.

Enter Dimensions

Simply pop in your bed’s length, width, and depth, then choose your material – compost, bark, or topsoil. The calculator instantly converts that into total volume, weight, and the number of bags to buy. You can even switch between metric and imperial units, perfect whether you think in metres or still measure things “by the foot”.

Material Densities

We’ve also factored in real-world densities, so lighter materials like bark go further than compost, meaning you won’t overspend or overfill. Whether you’re topping up raised beds, refreshing your borders, or creating a new flower sanctuary from scratch, this calculator keeps your green-fingered projects efficient and wallet-friendly.

So before you lug another heavy bag into your trolley, give this calculator a whirl – your back (and budget) will thank you.

Final Word

Well, there you have it, your one-stop soil sanity-saver. No more overbuying, underestimating, or panic trips back to the garden centre covered in dirt and regret. This calculator’s got your back, whether you’re laying compost for a veggie patch or spreading bark mulch like a pro landscaper.
