Garden Path Calculator
— How Much Do You Need?

The best gravel for your garden path depends on the look you want and how much foot traffic the path will see. Pea gravel is one of the most popular choices for garden paths. It is small, smooth, and rounded, which makes it comfortable to walk on barefoot and gives any path a natural, relaxed feel. It comes in a range of earth tones and blends well into cottage gardens, formal landscapes, and everything in between. It also shifts underfoot more than angular stone. For a surface that firms up and stays put, angular crushed stone is the better option. The jagged edges lock together under foot traffic, which means the surface gets more stable over time. Decomposed granite is another option that compacts into a smooth, firm surface. For most homeowners, pea gravel or a fine crushed stone are the go-to materials.

For a garden path built for regular foot traffic, a finished depth of 2 to 3 inches is the standard recommendation. That is enough to walk comfortably, provides good drainage, and gives the path a complete, finished appearance without using more material than the project calls for. To estimate how much gravel you need, start by measuring the full length and width of your path in feet, then multiply those numbers together to get the total square footage. From there, your depth drives the tonnage. At 2 inches of depth, one ton of gravel covers roughly 100 to 120 square feet. At 3 inches of depth, that same ton covers closer to 70 to 80 square feet. Keep in mind that rounded gravel like pea gravel and angular crushed stone have slightly different densities, so real-world coverage can vary a little depending on the material you choose. A garden path that is 3 feet wide and 50 feet long covers 150 square feet. At 3 inches depth, that is around 2 tons of material. If you are planning multiple paths, adding a patio, or combining your path with other landscaping work, the total tonnage adds up quickly and a bulk truckload covers more ground than you might expect. Use the Hello Gravel calculator on this page to plug in your exact dimensions and get a precise tonnage estimate before you order.

You can lay gravel directly on soil, but skipping prep tends to cause problems that are frustrating to fix later. When gravel sits directly on bare soil, it can sink over time, weeds push up from below, and the path surface becomes uneven. The recommended approach is to excavate the path area to a depth of 4 to 6 inches before adding gravel. Lay a sheet of landscape fabric to block weeds and prevent gravel from mixing into the soil. After that, pour gravel on top and rake to an even depth of 2 to 3 inches. If the soil is soft, adding a thin layer of base material under the finish gravel will improve stability. This prep pays off in long lasting looks and performance.

Building a gravel garden path is a straightforward project. Mark the path with stakes and a string line, then excavate the area to 4 to 6 inches, removing grass and roots and keeping the bottom level. Install edging on both sides to keep the gravel in place, using metal, timber, brick, or plastic edging. Lay landscape fabric over the floor, then pour gravel on top and rake to a 2 to 3 inch depth. If using angular crushed stone, you can walk the path back and forth a few times to help compact it; pea gravel will settle naturally. Hello Gravel delivers by the truckload, and you can use the calculator to estimate how much to order before delivery.

Two things handle most of the work: edging and a weed barrier. Edging keeps gravel from migrating into lawns or beds; metal landscape edging is a common durable choice, but timber, brick, or plastic edging also work. A weed barrier under the gravel blocks many weeds from pushing up through the ground. Over time, some weeds may appear on the surface and can be controlled with a quick hand weeding or a top-up of gravel. For rounded gravel like pea gravel, you can add a base layer to improve stability. The path remains low maintenance when built with good edging and base.
