Know your square footage.
Rectangles, circles, triangles — or walk the actual perimeter of an odd-shaped bed and get a real number.
Measure all three sides — this works for any triangle, not just right angles.
Walk the edge clockwise. For each side, enter its length and the corner angle at the end of that side (90° for a square corner).
The shapes that cover most yards.
Straight math, no rounding tricks — exact area and perimeter every time.
For everything else.
Enter side lengths and corner angles as you walk the bed, and watch the shape draw itself.
Measure once, reuse everywhere.
Send your area straight into the material calculator, or your perimeter into stake spacing.
Stop guessing bags.
Turn square footage and depth into cubic yards, bags, and a ballpark cost — bulk vs. bagged, side by side.
Defaults are ballpark U.S. big-box prices — edit them to match your supplier.
| Option | Amount | Est. cost |
|---|---|---|
| Bagged | — | — |
| Bulk delivery | — | — |
Mulch, soil, gravel, sand, compost.
Each with its own typical bag size — all editable.
See both, pick the cheaper one.
Bagged is convenient for small jobs; bulk usually wins past a couple of yards.
Depth chips for common jobs.
Top-ups, fresh beds, and gravel bases each want a different depth — pick a preset or set your own.
Light it without the dim end.
Work out how many fixtures you need, then run the voltage-drop math so the farthest light isn't the dim one.
Voltage drop is the #1 reason the last fixture on a run looks dim — this checks it before you bury the wire.

Spacing presets built in.
Path lights, border wash, or wide accent spacing — pick a preset or dial in your own.
The check most free tools skip.
Wattage, distance, and wire gauge — the same math pro installers use before they trench a run.
A straight answer, not just a number.
Know immediately if you should upsize the wire or split the circuit.
Every stake, evenly spaced.
No awkward leftover gap at the end — get the exact interval and the total count.
Staking a run for lights or a water feature? See YardSocket for getting outdoor power out to where the stakes go.
Fence-lines and full loops.
Straight runs need an end stake on both sides; loops don't — the math adjusts either way.
No fractional leftover.
Get the exact interval that divides evenly, right alongside what you asked for.
Perimeter carries over.

Yard calculator FAQ
How do I find the square footage of my yard?
Open the Lawn Area tool and pick a shape — rectangle, circle, triangle, or walk-the-sides for irregular beds. Enter your measurements in feet to get the area and perimeter.
How many bags of mulch, soil, or gravel do I need?
Use the Material calculator: enter the area, depth in inches, and bag size. It returns cubic yards and cubic feet, plus a bagged vs. bulk-delivery cost comparison.
How many landscape lights do I need for a path?
In the Lighting tool, enter the run length and target spacing to get the fixture count and the actual even spacing. The voltage-drop check then tells you whether your wire gauge can handle the run.
How do I space stakes evenly along a fence line or border?
Enter the total length and target spacing in the Stake Spacing tool. It adjusts the interval so there is no leftover gap and handles both open runs and closed loops.
Are these calculators free, and is my data uploaded?
Yes, they are free with no signup. All calculations run on your device in the browser.
