Travertine Mulch Chart: 5600 Sq Ft, 3 Inches, Order 58 Yards
On the defaults — a 5600 square foot bed at 3 inches deep with a 10% waste allowance — you need 6,160.00 square feet of cover, 57.04 cubic yards exact, so order 58 cubic yards. This is the TRAVERTINE version — the mulch chart for travertine, a warm-toned natural stone with a pitted surface that drains well, holds its colour and never breaks down — the quartzite-mulch-chart page is the QUARTZITE version, the sandstone-mulch-chart page is the SANDSTONE version, and the mulch-chart page is the GENERAL version for any loose mulch.
What does 57.04 cubic yards of travertine mulch mean?
It means a 5600 square foot bed, once the 10% waste allowance is added, needs 6,160.00 square feet of cover at 3 inches deep — 1,540.00 cubic feet, which is 57.04 cubic yards. Because mulch is sold by the whole yard, you order 58 cubic yards: the exact figure sits 0.96 yards below the next whole yard, so the order carries 0.96 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 38.02 yards, and at 4 inches it would need 76.05 yards.

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: travertine does not break down, so the layer you spread is the layer that stays — but the stones scatter onto paths and lawns when raked or walked on, so edge the bed if you want the depth to hold. Third, do not skip the waste allowance on travertine: the stones are pitted and angular and lock together, so they stay put better than round gravel on slopes, but 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 58 yards carries 0.96 yards of headroom, which covers ordinary spillage on a bed like this one.
Worked example
Area 5600 sq ft, depth 3 inches, waste 10%. Area needed: 5600 × 1.10 = 6,160.00 sq ft. Exact volume: 6,160.00 × 3 ÷ 324 = 57.04 cubic yards. Order: round 57.04 up to 58 cubic yards. Drop the waste to 0% and the exact volume falls to 51.85 yards, order 52; raise the waste to 5% and it is 54.44 yards, order 55; raise it to 15% and it is 59.63 yards, order 60. Drop the depth to 2 inches and it falls to 38.02 yards, order 39; raise it to 4 inches and it climbs to 76.05 yards, order 77. Depth moves the answer faster than waste does, because every inch adds a full layer across the whole bed.
Travertine 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 |
|---|---|---|---|---|
| 250 | 2 | 275.00 | 1.70 | 2 cubic yards |
| 250 | 3 | 275.00 | 2.55 | 3 cubic yards |
| 500 | 2 | 550.00 | 3.40 | 4 cubic yards |
| 500 | 3 | 550.00 | 5.09 | 6 cubic yards |

Every branch, checked
A 5600 square foot bed at 3-inch depth with 0% waste gives 51.85 cubic yards exact, order 52 cubic yards. The same bed at 2-inch depth with 10% waste gives 38.02 cubic yards exact, order 39 cubic yards. A 5350 square foot bed at 3-inch depth with 10% waste gives 54.49 cubic yards exact, order 55 cubic yards. A 5850 square foot bed at 3-inch depth with 10% waste gives 59.58 cubic yards exact, order 60 cubic yards. Each branch changes exactly one input, so the difference from 57.04 isolates that input.
The reverses, worked backwards
The area behind 57.04 cubic yards is 5600 sq ft: at 5350 sq ft the figures are 54.49 cubic yards exact, order 55 cubic yards, and at 5850 sq ft they are 59.58 cubic yards exact, order 60 cubic yards. The depth behind 57.04 cubic yards is 3 inches: at 2 inches the figures are 38.02 cubic yards exact, order 39 cubic yards, and at 4 inches they are 76.05 cubic yards exact, order 77 cubic yards — one inch either way moves the order by about 19.0 yards. The waste behind 57.04 cubic yards is 10%: at 5% the figures are 54.44 cubic yards exact, order 55 cubic yards, and at 15% they are 59.63 cubic yards exact, order 60 cubic yards — waste moves the exact volume, and at 15% it lifts the order to 60 yards.
What the defaults assume
The defaults assume a flat 5600 square foot bed, a uniform 3-inch layer, and a 10% waste allowance. Real travertine beds are rarely flat: slopes shed stones downhill, paths and tree trunks eat into the area, and loose stones 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 with travertine: the 5600 square foot headline is a large garden bed, and the table covers everything from a 250 square foot border to a 3000 square foot yard. A landscaper quoting a travertine job: the waste column protects the quote, and the order column is the number given to the supplier. A homesteader spreading bulk travertine on paths: 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 stones scatter, or a skipped waste allowance will each move the answer by exactly the amount of the error, every load. The model does not include stones scattering into lawns, delivery minimums, or compaction — 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 travertine mulch really be?
Three inches is the standard bed layer on this page, and 2 inches suit paths and top-ups. Travertine does not break down, so a 3-inch spread stays 3 inches; if stones scatter, rake them back or top up the thin spots.
Does travertine mulch introduce weed seeds?
Travertine 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 58 yards when the exact figure is 57.04?
Because mulch is sold by the whole yard, and 57.04 rounds up to 58 — the order carries 0.96 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. Travertine does not settle like bark, so use the travertine rows for travertine and the matching chart for bark or wood chips.
