Bagged mulch is handy for small beds; bulk by the cubic yard is cheaper past about 10 bags. One cubic yard equals roughly thirteen 2 ft³ bags.

Mulch settles, so a fresh 3 in layer thins over the season. Top up rather than piling it against trunks and stems.

How it works

  1. 1

    Measure the bed

    Enter the length and width of the bed or area you are mulching.

  2. 2

    Set the depth

    Two to three inches refreshes a bed; three to four suppresses weeds.

  3. 3

    Get the amount

    See the cubic yards for bulk and the number of bags at your bag size.

Frequently asked questions

How much mulch do I need?
Multiply length by width by depth in feet, divide by 27 for cubic yards, or by the bag volume for bags. The calculator does both so you can compare.
How many bags of mulch in a cubic yard?
A cubic yard is 27 cubic feet, so it holds about thirteen 2 ft³ bags or nine 3 ft³ bags. Bulk is usually cheaper past roughly ten bags.
How deep should mulch be?
Two to three inches is enough for most beds; three to four blocks weeds. Keep it off trunks and stems and top up as it breaks down.
Are these numbers exact?
They are close planning estimates, not a substitute for a contractor takeoff. Real quantities depend on your terrain, post spacing, waste and local building code, so buy a little extra and confirm against your supplier.
Is my fence design sent anywhere?
No. Everything runs in your browser. The layout, lengths and prices you enter stay on your device, nothing is uploaded, logged or stored, and it all clears when you close the tab.
