Gravel & Dirt Master
Always verify with your local quarry.
Every landscaping project begins with a pile of dirt or rock. But ordering that pile is a high-stakes guessing game. Order too little, and you pay a second delivery fee (often $100+) for a small amount. Order too much, and you are left shoveling a mountain of leftover gravel into the woods.
The Gravel & Dirt Calculator takes the guesswork out of the yard. It converts your project dimensions (Length x Width x Depth) into precise Volume (Cubic Yards) and Weight (Tons) for specific materials like #57 Stone, Mulch, Topsoil, and Sand.
How to Use This Calculator
Follow these three simple steps to get a quote-ready number:
1. Measure the Area
Measure the Length and Width of the driveway, path, or garden bed. If you have an irregular shape, break it into rectangles and sum them up.
2. Choose Your Depth
Depth is critical. Standard recommendations are:
- 2-3 Inches: Decorative mulch or flower bed top dressing.
- 4-6 Inches: New gravel driveways or walking paths.
- 12+ Inches: Filling a raised garden bed.
3. Select Material (Density)
Different materials weigh differently. A cubic yard of mulch is light; a cubic yard of wet sand is incredibly heavy. Select your material from the dropdown to apply the correct density factor.
Understanding Material Weights
Gravel & Crushed Stone
Gravel is dense. Standard #57 limestone or granite weighs about 1.4 tons per cubic yard.
- Uses: Driveways, drainage, French drains.
- Note: “Crusher Run” (stone mixed with dust) compacts harder and may require slightly more tonnage.
Topsoil & Dirt
Loose, dry topsoil weighs about 1.0 – 1.2 tons per cubic yard. However, wet soil can weigh significantly more (up to 1.5 tons).
- Uses: Filling holes, grading lawns, raised beds.
- Tip: Always buy “screened” topsoil to avoid roots and rocks.
Sand
Sand is deceivingly heavy, weighing 1.3 – 1.5 tons per cubic yard depending on moisture content.
- Uses: Paver base, mixing concrete, play sandboxes.
Mulch
Mulch is sold by Volume (Cubic Yards), not Weight, because it is so light (~600-800 lbs/yard).
Pro Tips for Ordering
The “Compaction Factor”
Loose material settles. When you spread 4 inches of loose gravel on a driveway and drive on it, it packs down to 3 inches. Always order 10-15% extra to account for compaction and settling over time.
Truck Capacity
Know your limits:
- Pickup Truck: Hauls 0.5 – 1.0 cubic yard (Warning: Watch your payload weight!).
- Single Axle Dump Truck: Hauls 5 – 7 tons (approx 4-5 yards of gravel).
- Tri-Axle (Standard Dump): Hauls 20 – 22 tons (approx 15 yards of gravel).
Frequently Asked Questions (FAQ)
What is a “Yard” of dirt?
It refers to a Cubic Yard (). It is a measure of volume, roughly the size of a washing machine.
Can I put fresh gravel over old gravel?
Yes, this is called “top dressing.” You typically only need 1-2 inches of new stone to freshen up an existing driveway, rather than the full 4 inches needed for a new one.
Why does the calculator ask for weight?
Quarries sell stone by the Ton (scale weight). Garden centers sell mulch by the Yard (bucket volume). This calculator gives you both numbers so you can speak the seller’s language.
Final Words
Don’t let a simple weekend project turn into a logistical nightmare. The Gravel & Dirt Calculator gives you the professional numbers you need to order with confidence. Save money, save your truck’s suspension, and get the job done right.
