Screened Topsoil Calculator
— How Much Do You Need?

Screened topsoil starts out as natural topsoil, which is the upper layer of earth richest in organic matter and nutrients. Before it reaches you, it is run through a mechanical screen that removes rocks, roots, clumps, and other debris. The result is a clean, fine-textured soil that is consistent and easy to spread across any surface. Regular dirt, often called fill dirt, is typically subsoil. It sits below the topsoil layer, contains little to no organic matter, and is not suited for growing plants. It works well for large fill and grading jobs where plant growth is not the goal, but it will not give your lawn or garden beds what they need to thrive. Unscreened topsoil is topsoil in its raw form before any processing takes place. It can still contain clods, rocks, and debris, which makes it harder to spread evenly and less suitable for planting beds or fine finish grading. When you order screened topsoil, you are getting the cleaner, more workable version. It is the right choice whenever you need soil that plants can grow in and that you can spread smoothly across a surface.

Screened topsoil is one of the most versatile materials you can order for yard and garden work. It is the go-to choice for establishing a new lawn, whether you are laying sod or seeding from scratch. The fine, debris-free texture gives grass roots an easy path to take hold and spread. It is also excellent for filling and leveling low spots in your yard. If you have depressions that collect standing water after rain, a layer of screened topsoil can even things out and give you a smoother, healthier surface. For garden beds, raised planters, and general landscaping work, it gives plants a nutrient-rich medium to grow in right from the start. Contractors and landscapers also rely on screened topsoil to backfill around foundations, trees, and shrubs, and to finish grade a property before seeding or sodding. If your project involves anything where plants need to grow or where you want a clean, smooth finish to the soil surface, screened topsoil is the right material for the job.

For most common projects, yes, you can plant directly into screened topsoil. Grass seed, sod, shrubs, flowers, and many vegetables will all establish well in a quality screened topsoil without any additional amendments. It has enough organic content and workable texture to support plant growth right away. That said, every yard is different. If you are starting a high-production vegetable garden or working with plants that need especially rich or moisture-retentive soil, mixing in compost can give you an added boost. But for lawn establishment and general landscaping, screened topsoil on its own is typically all you need to get things growing. The key is making sure you apply enough depth. For seeding a new lawn, a 2-to-4-inch layer gives roots plenty of room to develop. For deeper planting beds, 6 or more inches is ideal. Use the Hello Gravel calculator to figure out exactly how much material you will need based on your specific dimensions before you place your order.

Yes, and it is a well-established technique called topdressing. A thin layer of screened topsoil spread across your existing lawn can help fill in minor low spots, improve the soil composition beneath the grass over time, and create a better environment for new seed to germinate when you overseed in the same pass. The key word is thin. A light application of roughly a quarter to half an inch allows the existing grass to breathe and grow up through the new soil. If you apply too thick a layer, you risk smothering the turf you already have. If you are trying to raise the grade significantly or fill depressions deeper than about an inch, you will get better results by removing or tilling the existing turf first, applying your screened topsoil to the right depth, and then reseeding. For a precise estimate of how much material either approach requires, the Hello Gravel calculator is the fastest way to work out the right quantity for your specific area.

Coverage depends entirely on how deep you spread the material. At 1 inch of depth, one cubic yard covers roughly 324 square feet. At 2 inches deep, that drops to about 162 square feet. At 3 inches deep, you are looking at around 108 square feet, and at 4 inches deep, approximately 81 square feet. For establishing a new lawn, most projects call for a 2-to-4-inch layer. If you are topdressing an existing lawn, a quarter to half an inch is usually sufficient. Garden beds typically benefit from 4 to 6 inches of screened topsoil to give plants a healthy growing environment. These figures give you a solid starting point, but your actual needs depend on the specific dimensions of your space and how much uneven ground you need to account for. The Hello Gravel calculator makes it simple to enter your square footage and target depth to get a reliable estimate of how many yards to order. Taking a few minutes to run those numbers before you place your order helps make sure you get enough material the first time without over-ordering.
