Stop guessing in the garden center. Calculate exact cubic yardage, determine how many bags you need, and find out if ordering a bulk delivery is cheaper. This free online tool allows you to calculate mulch and soil quickly and accurately. No sign-up or installation required.
Every spring, millions of homeowners stand in the parking lot of a hardware store staring blankly at a pallet of mulch, trying to guess how many bags will cover their front yard. They usually guess wrong, resulting in multiple frustrating trips to the store or thin, inadequate weed protection.
Whether you are building raised beds for a vegetable garden, top-dressing a lawn with compost, or laying decorative bark mulch, landscaping materials are always sold by volume, not area. This guide breaks down the math of cubic yardage and helps you solve the ultimate landscaping dilemma: Bulk Delivery vs. Bagged Material.
The reason volume math is difficult is that depth drastically changes the total requirement. A garden bed that is 20 feet long and 10 feet wide requires 0.6 yards of mulch if you lay it 1-inch thick. But if you lay it at the recommended 3-inch thickness, the requirement triples to nearly 2 full yards.
Our calculator handles all of this cross-dimensional math instantly. You simply input the length and width of your garden bed, set your target depth using the slider, and the calculator yields exact cubic yardage (or cubic meters, if you are using the Metric system).
In the United States, standard bags of mulch or garden soil contain exactly 2 cubic feet of material. Because a cubic yard is 27 cubic feet, it takes exactly 13.5 bags to equal one yard (27 ÷ 2 = 13.5). If your landscaping project requires 3 cubic yards of mulch, you must load and haul 41 individual bags.
The most common question in landscaping is whether it is cheaper to order a dump truck delivery or buy bags. The answer depends entirely on your total volume and your vehicle.
Using our built-in Budget Estimator, you can toggle between bulk pricing and bag pricing. Input your local prices to instantly find out which method is most cost-effective for your specific project.
If you decide to pick up bulk material yourself to avoid the delivery fee, know your payload capacity. A cubic yard of dry topsoil weighs 2,000 lbs. A standard half-ton pickup (F-150, Silverado 1500, Ram 1500) generally maxes out around 1,500 to 1,800 lbs in the bed. Having the loader operator dump a full yard of wet soil into your truck will compress your suspension to the frame and create a severe driving hazard.
