BackyardFigures Your yard, figured out

Measure once – buy right no guessing – just math

Why BackyardFigures exists

Every yard project starts with the same simple question: how much do I actually need? How many bags of mulch for the flower beds along the driveway? How many cubic yards of topsoil to level out that low corner of the lawn? How many pounds of grass seed for the bare patches the dog left behind last summer? It sounds easy – until you’re standing in the garden center aisle, staring at bags labeled in cubic feet, while the landscape supplier down the road only sells by the cubic yard or the ton.

Most people end up guessing. And guessing is expensive. Buy too little, and you’re back in the truck for a second trip – or paying a second delivery fee, which can cost more than the material itself. Buy too much, and you’re left with a pile of gravel on the driveway, half a pallet of sod drying out in the sun, or a bag of fertilizer that sits in the garage for three years. Over-applying seed or fertilizer doesn’t just waste money, either: it can weaken your lawn and wash nutrients into storm drains and streams.

BackyardFigures was built to take the guesswork out of that first step. The idea is simple: one place with clear, fast, free calculators for the materials homeowners buy most often. No sign-up, no email address, no app to download. You enter your measurements, and the answer appears instantly – in the units stores and suppliers actually use. Cubic feet and cubic yards for mulch and soil. Tons for gravel. Pallets and pieces for sod. Pounds for seed and fertilizer. Every calculation runs right in your browser, so it works on your phone in the store just as well as on your laptop at home.

We also know that a number alone isn’t always enough. That’s why each calculator comes with short, practical guidance: how deep mulch should really be, how much a yard of topsoil weighs before you try to haul it in a half-ton pickup, which seeding rate fits tall fescue versus Bermuda grass, and what the three numbers on a fertilizer bag mean. The rates and material weights we use are typical values from manufacturers and university extension publications. Products and site conditions vary, so treat our results as a reliable starting point and always double-check the label or ask your supplier before you order.

Whether you’re refreshing a few garden beds this weekend, building raised beds for your first vegetable garden, laying a new gravel path or bringing a tired lawn back to life, the goal is the same: buy the right amount the first time, spend less, and get back to the part of yard work that’s actually fun.

We’re adding new calculators and guides regularly. If there’s a tool you’re missing, let us know – we read every message.

How to measure your yard

For rectangles, measure length and width in feet. For round beds, measure across the widest point (the diameter). Irregular areas are easiest to split into a few rectangles – calculate each one and add the totals, or use the “Total area” option.

Depth is usually entered in inches. If you’re unsure, each calculator recommends a typical depth for the job.
