Material Calculator

Estimate how much material you need to cover one or more areas at your chosen depth, plus what it will cost. A 2 to 4 inch layer is right for most beds.

Cubic meters
Liters
2 cu ft bags (standard)
3 cu ft bags (large)

Bag counts are rounded up to whole bags. Buying 5 to 10% extra covers settling and uneven ground.

Plant Calculator

Figure out how many plants you need, what spacing to use, or how much area a set number of plants will cover. Closer spacing fills in faster; wider spacing uses fewer plants but takes longer to look full.

Fill in any two fields and the third will be calculated for you.

Sun Position & Shadow Calculator

See where the sun sits in the sky at any location, date, and time: its compass direction, height above the horizon, the shadow it casts, and the day's sunrise, sunset, and golden hour times. Drag the time slider to watch the sun move across its daily path.

Overhead view. Outer ring is the horizon, center is straight up. The arc is today's sun path; the line from center is the shadow direction.
