Hickory Bark Mulch Chart: 8200 Sq Ft, 3 Inches, Order 84
On the defaults — a 8200 square foot bed at 3 inches deep with a 10% waste allowance — you need 9,020.00 square feet of cover, 83.52 cubic yards exact, so order 84 cubic yards. This is the HICKORY version — the mulch chart for hickory, a shredded hardwood bark in warm brown tones with a coarse, stringy texture, laid for beds and paths, that breaks down slowly over several seasons.
What does 83.52 cubic yards of hickory mulch mean?
It means a 8200 square foot bed, once the 10% waste allowance is added, needs 9,020.00 square feet of cover at 3 inches deep — 2,255.00 cubic feet, which is 83.52 cubic yards. Because mulch is sold by the whole yard, you order 84 cubic yards: the exact figure sits 0.48 yards below the next whole yard, so the order carries 0.48 yards of headroom for spillage and uneven ground. At 3 inches, one cubic yard covers 108.0 square feet, so the same bed at 2 inches would need only 55.68 yards, and at 4 inches it would need 111.36 yards.
Output · formula · meaning
| Output | Formula | What it means |
|---|---|---|
| Area needed | area × (1 + waste ÷ 100) | 9,020.00 sq ft — 8200 × 1.10. |
| Volume in cubic feet | area needed × depth ÷ 12 | 2,255.00 cubic feet — 9,020.00 × 3 ÷ 12. |
| Exact volume | area needed × depth ÷ 324 | 83.52 cubic yards — 9,020.00 × 3 ÷ 324. |
| Order quantity | round exact volume up to a whole yard | 84 cubic yards — the next whole yard above 83.52. |
| Coverage per yard | 324 ÷ depth | 108.0 sq ft per yard — 324 ÷ 3. |
| Area behind a target volume | target volume × 324 ÷ depth ÷ (1 + waste ÷ 100) | 8200 sq ft — 83.52 × 324 ÷ 3 ÷ 1.10, rounded. |
| Depth behind a target volume | area needed × depth ÷ 324, solved for depth | 3 inches — the depth that turns 9,020.00 sq ft into 83.52 yards. |
| Waste behind a target volume | target volume × 324 ÷ depth ÷ area − 1, as a percent | 10% — the allowance that turns 8200 sq ft into 9,020.00 sq ft. |
Three things to check before you trust the number
First, measure the bed honestly: length times width for each bed, added together, with L-shaped beds split into rectangles. A guessed area moves the order by the same percentage as the guess. Second, keep the depth honest: hickory does not break down, so the layer you lay is the layer that stays — and the pieces are angular, so they lock together and hold their depth on slopes better than round stones do, though loose pieces at the edges still wander. Third, do not skip the waste allowance on hickory: even tightly packing angular pieces leave gaps, and spillage at the edges and uneven ground still eat into the load, so the 10% allowance is the difference between finishing the bed and running short with the truck already gone. The headline order of 84 yards carries 0.48 yards of headroom, which covers ordinary spillage on a bed like this one.
Worked example
Area 8200 sq ft, depth 3 inches, waste 10%. Area needed: 8200 × 1.10 = 9,020.00 sq ft. Exact volume: 9,020.00 × 3 ÷ 324 = 83.52 cubic yards. Order: round 83.52 up to 84 cubic yards. Drop the waste to 0% and the exact volume falls to 75.93 yards, order 76; raise the waste to 5% and it is 79.72 yards, order 80; raise it to 15% and it is 87.31 yards, order 88. Drop the depth to 2 inches and it falls to 55.68 yards, order 56; raise it to 4 inches and it climbs to 111.36 yards, order 112. Depth moves the answer faster than waste does, because every inch adds a full layer across the whole bed.
Hickory bark mulch lookup table
Every row below applies 10% waste to the area first, then divides by 324: yards = area needed × depth ÷ 324, rounded up to the next whole yard for the order. Find your bed size and depth, read across, and order the last column.
| Area (sq ft) | Depth (inches) | Area needed (sq ft, 10% waste) | Exact (cubic yards) | Order |
|---|---|---|---|---|
| 300 | 2 | 330.00 | 2.04 | 3 cubic yards |
| 300 | 3 | 330.00 | 3.06 | 4 cubic yards |
| 600 | 2 | 660.00 | 4.07 | 5 cubic yards |
| 600 | 3 | 660.00 | 6.11 | 7 cubic yards |
| 800 | 3 | 880.00 | 8.15 | 9 cubic yards |
| 800 | 4 | 880.00 | 10.86 | 11 cubic yards |
| 1100 | 2 | 1,210.00 | 7.47 | 8 cubic yards |
| 1100 | 3 | 1,210.00 | 11.20 | 12 cubic yards |

Every branch, checked
A 8200 square foot bed at 3-inch depth with 0% waste gives 75.93 cubic yards exact, order 76 cubic yards. The same bed at 2-inch depth with 10% waste gives 55.68 cubic yards exact, order 56 cubic yards. A 7900 square foot bed at 3-inch depth with 10% waste gives 80.46 cubic yards exact, order 81 cubic yards. A 8500 square foot bed at 3-inch depth with 10% waste gives 86.57 cubic yards exact, order 87 cubic yards. Each branch changes exactly one input, so the difference from 83.52 isolates that input.
The reverses, worked backwards
The area behind 83.52 cubic yards is 8200 sq ft: at 7900 sq ft the figures are 80.46 cubic yards exact, order 81 cubic yards, and at 8500 sq ft they are 86.57 cubic yards exact, order 87 cubic yards. The depth behind 83.52 cubic yards is 3 inches: at 2 inches the figures are 55.68 cubic yards exact, order 56 cubic yards, and at 4 inches they are 111.36 cubic yards exact, order 112 cubic yards — one inch either way moves the order by about 27.8 yards. The waste behind 83.52 cubic yards is 10%: at 5% the figures are 79.72 cubic yards exact, order 80 cubic yards, and at 15% they are 87.31 cubic yards exact, order 88 cubic yards.
What the defaults assume
The defaults assume a flat 8200 square foot bed, a uniform 3-inch layer, and a 10% waste allowance. Real hickory beds are rarely flat: paths and tree trunks eat into the area, and loose pieces at the edges wander into the lawn, so measure the planted area only and keep the waste allowance on sloped ground. Zero square feet is the honest edge: 0.00 cubic yards exact, order 0. A depth of zero or below, a negative area, or a negative waste allowance is rejected, because none of them describes a real bed.
Who uses this
A gardener dressing beds and paths with hickory: the 8200 square foot headline is a large garden bed or a long drive, and the table covers everything from a 300 square foot border to a 3200 square foot yard. A landscaper quoting a hickory job: the waste column protects the quote, and the order column is the number given to the supplier. A homeowner laying hickory on a path: the 3-inch rows are the bed depths, and the 2-inch rows are the path depths. A community garden coordinator splitting a bulk delivery: each plot reads its own row, and the orders add up to the truckload.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is in the inputs. A guessed area, a depth measured before the pieces settle, or a skipped waste allowance will each move the answer by exactly the amount of the error, every load. The model does not include pieces wandering at the edges, delivery minimums, or the gaps between angular pieces — a supplier may sell only in whole yards or charge extra below a minimum, so confirm the order quantity with the supplier.

Frequently asked questions
Why does the table apply waste to the area first?
Because waste is lost cover: spillage, scattering and uneven ground mean you need more covered area than the bed measures. Adding 10% to the area, then converting to yards, keeps the waste in the same units as the bed. Applying it after the conversion gives the same number here, but the area-first order keeps the table readable.
How deep should hickory mulch really be?
Three inches is the standard bed layer on this page, and 2 inches suit paths and top-ups. Hickory does not break down, so a 3-inch spread stays 3 inches; if pieces scatter, set them back or top up the thin spots.
Does hickory mulch introduce weed seeds?
Hickory is mineral, so it carries no weed seeds at all; weeds can still root in the dust and debris that collects on top of it, so use fabric underneath and clear the debris. This calculator prices volume only and does not judge the gardening choice.
What if my bed is not a rectangle?
Split it into rectangles, measure each, and add the areas before entering the total. A circle uses radius times radius times 3.14. Guessing one number for an irregular bed is the most common reason orders come up short.
Why order 84 yards when the exact figure is 83.52?
Because mulch is sold by the whole yard, and 83.52 rounds up to 84 — the order carries 0.48 yards of headroom for spillage and uneven ground. That headroom is the buffer the exact figure does not have.
Can I use this chart for other mulch types?
The volume math is the same for any loose mulch — area, depth and waste convert the same way — but settling and coverage differ by material. Hickory does not settle like bark, so use the hickory rows for hickory and the matching chart for bark or wood chips.
