Landscaping Calculators

Planning a landscaping project means answering one question before you pick up a shovel: how much material do you actually need? Whether you are laying a gravel pathway along the side of your house, filling raised garden beds with fresh topsoil, spreading mulch around shrubs, or building a French drain with washed stone, every project starts with accurate quantity estimates. Order too little and you stall mid-project waiting for a second delivery. Order too much and you are stuck with expensive leftover piles that take up driveway space for weeks. Our landscaping calculators remove the guesswork by converting your measurements into the exact units that suppliers sell — cubic yards for bulk delivery, tons for weight-priced aggregates, and bag counts for smaller pickup-truck runs.

Each calculator below is built for a specific material type so the density conversions, waste factors, and coverage depths match real-world supplier data. Enter your project dimensions — length, width, and desired depth — and the tool returns a purchase-ready quantity. You can combine multiple areas (rectangular beds, circular tree rings, triangular corner gardens) in a single calculation session and see a running total. The results include bulk and bagged options side by side, making it easy to compare pricing at your local landscape supply yard. Use these tools to plan anything from a simple mulch refresh to a full backyard renovation involving gravel bases, decorative stone borders, topsoil grading, and sand leveling layers.

Frequently Asked Questions

Which calculator should I use first? +
Start with the calculator that matches the largest area of your project. For most yards, that means the Gravel Calculator for pathways and drainage bases, or the Mulch Calculator for garden beds. If you are building up a new lawn or filling raised beds, begin with the Topsoil Calculator instead. Once you know the volume for your biggest material, move on to the smaller areas — the running totals will help you combine everything into a single supplier order and potentially qualify for bulk delivery pricing.
What's the difference between gravel and crushed stone? +
Gravel refers to naturally rounded rock that has been screened to a uniform size, while crushed stone is mechanically broken rock with angular edges. The angular edges of crushed stone make it lock together better, so it is the preferred choice for driveway bases and paver sub-bases. Round gravel drains faster and is easier to walk on, making it ideal for garden paths and decorative ground cover. Both materials are sold by the cubic yard or by the ton — our Gravel Calculator and Stone Calculator handle the volume-to-weight conversion for either type so you can order confidently.
How do I measure an irregular yard area? +
Break the space into simple shapes — rectangles, triangles, and circles — then add their areas together. For curved garden beds, approximate the shape as a series of rectangles or use the "irregular area" option available in each calculator. Measure each section in feet (length and width), record the numbers, and enter them one at a time. The calculators let you add multiple areas before generating a combined total, so you do not have to do the math yourself. For very complex shapes, lay a garden hose along the border, measure the bounding rectangle, and subtract the corners you do not need.
