This free mulch calculator tells you exactly how much mulch, gravel, topsoil, sod, or grass seed your project needs, plus the cost, in seconds. No more guessing, no more wasted bags.
Area: 200 sq ft
Round up to whole yards or bags when you order.
1 cubic yard ≈ 13.5 bags (2 cu ft). Estimates only — settling and uneven ground can change real-world amounts.
The mulch calculator above works for any bulk landscaping material sold by volume or area. Pick your material, enter the size of the bed or lawn, set the depth, and you’ll get the cubic yards, bag count, and estimated cost instantly. Below is how the numbers work so you can order with confidence.
Measure the length and width of the bed or lawn in feet, then multiply them to get square feet (length × width = sq ft). For odd shapes, break the space into rectangles, measure each one, and add them together. For circles, multiply the radius by itself, then by 3.14. If you already know the square footage, just toggle the calculator to “Square Feet” and type it in.
For most beds, apply mulch 2 to 3 inches deep. Two inches is plenty for an annual refresh on an established bed; three inches is better for new beds or heavy weed suppression. Going deeper than 3 inches can suffocate roots and waste material. Keep mulch a couple inches away from tree trunks and plant stems so they don’t rot.
For decorative gravel and stone beds, 2 inches is a good default. For a gravel walkway or driveway base, plan on 3 to 4 inches (or more for vehicles). Crushed stone compacts, so order a little extra.
For filling or leveling, 3 to 4 inches of topsoil is typical. If you’re prepping a new lawn or garden bed, 4 to 6 inches gives roots room to establish. The calculator defaults topsoil to 3 inches.
This trips a lot of people up. One cubic yard equals 27 cubic feet. The most common bagged size is 2 cubic feet, so one cubic yard is about 13.5 bags. A 1.5 cubic foot bag gives you 18 bags per yard. Once you pass roughly 8 to 10 bags, bulk delivery by the yard is almost always cheaper than buying bags.
Sod is sold by the square foot, by the roll, and by the pallet. A standard roll covers about 10 square feet, and a pallet covers roughly 450 square feet. Order about 5% extra to account for trimming around curves and edges. Lay sod the same day it’s delivered and water it right away.
Grass seed is measured in pounds per 1,000 square feet. A typical new lawn needs about 5 lbs per 1,000 sq ft, while overseeding an existing lawn takes around 3 lbs per 1,000 sq ft. Rates vary by grass type, so check the seed bag and adjust the rate in the calculator if needed.
How much mulch do I need for 200 square feet?
At a 2-inch depth, 200 square feet needs about 33 cubic feet, which is roughly 1.25 cubic yards or 17 bags of 2 cubic foot mulch. Order 2 cubic yards if buying bulk.
How do I calculate cubic yards of material?
Multiply square feet by the depth in inches, divide by 12 to get cubic feet, then divide by 27 to get cubic yards. The calculator does all of this for you automatically.
Is bulk or bagged mulch cheaper?
Bulk is cheaper per unit once you need more than about 8 to 10 bags. For small touch-ups, bags are easier to haul and store. The calculator shows both so you can compare.
How many bags of mulch are on a pallet?
It varies by supplier, but most pallets hold 60 to 70 bags of 2 cubic foot mulch, which is roughly 4.5 to 5 cubic yards.
When should I apply mulch?
Late spring after the soil warms is ideal, once weeds are pulled and beds are clean. A lighter fall layer helps insulate roots through winter.
Stop guessing on material orders. Price the whole job for profit, quote faster, and never eat the cost of a short order again. The how to start a landscaping business guide and our done-for-you templates are all inside the kit.
