The mission behind YardFigure
The problem every homeowner knows
You're in the garden center, or on the phone with a supplier, trying to guess how many bags of mulch or cubic yards of gravel the job needs.
Guess low and you lose an afternoon to a second trip. Guess high and you've paid to deliver material that ends up dumped behind the shed.
Built by someone who checks the sources
YardFigure is built and maintained by Shaikh Abdul Wasey. I'm a developer, not a contractor — and that's exactly why every number on this site is traceable. I don't ask you to take a figure on trust. Each calculator shows its full working, each formula is checked against published industry guidance, and the sources are named on the page so you can follow them yourself.
Tools you can actually trust
Every calculator uses the standard formula for that material and shows its full working, so you can follow each step rather than trusting a black box. Where a figure is a typical range rather than a standard — regional prices, for instance — the page says so.
Three steps
How to use our calculators
Every tool works the same way, so once you've used one, you've used them all.
1. Measure your area
Measure the length, width, and the depth or thickness you want — in feet, inches, or metric. For an odd shape, split it into rectangles and add a row for each so they total together.
2. Enter your numbers
Type your measurements in and the result updates instantly — in cubic yards, cubic feet, bags, or tons, whichever way your supplier actually sells the material.
3. Add waste & order
Add a 5–10% waste allowance for spillage and uneven ground, check the worked math if you want to see how it adds up, then head to the supplier knowing exactly what to buy.
What you can plan
Material calculators for every part of the project
Four families of tools, each paired with the guides that explain the depth, the material type, and the mistakes to avoid.
Concrete & hardscaping
Slabs, footings, pads, and patios — volume in cubic yards, pre-mix bags, and paver counts with waste built in.
Garden & soil
Raised beds hold more than they look, which is where people over-spend most. Size one bed or several at once.
Mulch & ground cover
Mulch only works at the right depth. Get the bags or cubic yards to cover any area, without piling it against stems.
Base materials: gravel & sand
The layers under a slab or patio decide whether it lasts. Size your compacted base and bedding sand in tons, yards, and bags.
The case for measuring twice
Why an accurate estimate saves you money
Materials are bulky, heavy, and priced by volume — which makes a rough guess expensive in both directions.
Wrong costs you either way
Order too little and the job stops mid-pour — and with concrete, a gap between batches leaves a cold joint that weakens the slab. Order too much and you've paid to deliver material you now have to store, move, or dispose of.
The number decides how you buy
Bagged material suits small volumes. Past roughly half a cubic yard, bulk is usually cheaper per unit and far less work. Our results show cubic yards and bags, so you can price both routes before you commit.
Planned, not patched
Consistent depth across a bed, an even base under a patio, the right jointing sand in a paver run — these separate a result you're proud of from one you quietly redo next season.
Built to be trusted, not just used

Frequently asked questions
Are the calculators really free?
Yes — every calculator on YardFigure is completely free, with no signup, no account, and no app to install. You can use any of them as many times as you like, right in your browser.
What units do the calculators support?
All of them work in both imperial and metric. You can enter measurements in feet and inches or in centimeters and meters, and results are shown in cubic yards, cubic feet, cubic meters, bags, and tons where relevant — so the number matches how your supplier sells the material.
How accurate are the results?
Each calculator uses the standard formula the trade uses and shows the full working, including a worked example, so you can check the math yourself. Real deliveries vary slightly with compaction, uneven ground, and edge thickness, so we recommend treating the result as a close planning figure and adding a waste allowance before you order.
How much waste allowance should I add?
For most projects, 5–10% extra covers spillage, settling, and uneven subgrade. Add toward the higher end for irregular shapes with lots of cuts — such as a curved paver patio — where offcuts you can't reuse add up. Every calculator has an optional waste field so you can build this in automatically.
Do I need to create an account?
No. There is nothing to sign up for and nothing to download. The calculators run entirely in your browser, and we don't ask for an email to show you a result.
Can I use these on my phone at the store?
Yes. Every calculator is built to work on a phone, so you can measure at home, then check or adjust the numbers on your phone while you're standing in the aisle or talking to the supplier.
