Pine straw calculator.

Measured beds. The seller's own bale. Fresh or settled depth.

Beds & tree rings · seller bales · settling · boxes & pallets

Measure up to three landscape beds, select a seller bale preset or enter your supplier’s coverage figure, compare the bale count depending on whether the seller’s stated depth means settled needles or fresh straw, and round the order to single bales, 4-bale boxes, or 48-bale pallets.

6 bales (12–15 bales if seller depth is fresh) · 283.12 sq ft net

Gross bed area is 283.12 sq ft and net mulched area is 283.12 sq ft. To finish with your target settled layer, UGA Extension’s settling ratio corresponds to spreading 4 in to 5 in of loose fresh needles.

Fresh straw, settled straw and the seller's depth

Freshly spread pine straw settles. A UGA CAES Field Report article dated 2006-08-31 (read October 19, 2026) quotes UGA Extension consumer horticulturist Bob Westerfield: 4 to 5 in of fresh pine straw settles to about 2 in, and straw 2 in deep after settling does 90% of what you would expect a fabric or plastic liner to do—a 2 to 2.5 times settling ratio. Clemson Cooperative Extension HGIC’s Mulch sheet recommends a 2 to 3 in layer of pine needles for acid-loving trees and shrubs.

Sellers state coverage at different depths—2 in at The Pine Straw Store, 3 in at J&J Pine Needles, and 2.5 in at Mid-Atlantic Pine Straw (read October 19, 2026)—without saying whether that depth is fresh or settled. This tool shows both readings: on the default 283.12 sq ft layout at 2 in settled depth, you need 6 Pine Straw Store box bales if the seller’s depth is settled, or 12 to 15 bales if the seller’s depth is fresh (4 to 5 in spread).

Four seller bales on one scale

The calculator converts each preset to square-foot-inches per bale (k = coverage × stated depth) before dividing into your area and target depth:

On a 1,000 sq ft bed (40 × 25 ft) at 2 in settled depth, those four presets take 20, 16, 14, and 20 bales under the settled reading, or 40 to 50, 32 to 40, 27 to 34, and 40 to 50 bales under the 2× to 2.5× fresh reading.

Beds, tree rings and the sale unit

The tool sums up to three beds—rectangles, circles, tree rings (outer circle minus bare trunk circle), and triangles—minus bare exclusions. In the default setup, a 20 × 10 ft rectangle (200 sq ft), an 8 ft ring with a 2 ft trunk circle (47.12 sq ft), and a 12 × 6 ft triangle (36 sq ft) total 283.12 sq ft.

Choosing The Pine Straw Store’s 4-bale box (36 lb) or 48-bale pallet (576 lb) rounds up to whole packages: 6, 12, or 15 box bales round to 2, 3, or 4 boxes (8, 12, or 16 bales; 2, 0, or 1 leftover; 72, 108, or 144 lb).

Topping off an existing layer

The Pine Straw Store (read October 19, 2026) states that refreshing an existing bed uses about 60% of a fresh layer (4, 7, or 9 box bales on the 283.12 sq ft default layout, or 12 box bales on an 800 sq ft bed at 2.5 in settled depth). Clemson HGIC notes: “Pine needles and bark mulches typically last for around 2 to 4 years before the need to add more.” UGA CAES (2006) advises adding new straw on top of the old to make a layer at least 2 to 4 in thick, while noting that more than about 6 in adds no benefit.

Pine straw is not seeding straw

Search results often mix ornamental pine straw with grain straw spread over grass seed. Clemson Cooperative Extension’s Lawn Establishment guide (HGIC 1203, updated 2024) specifies 1 bale of grain straw (60 to 80 lb) for about 1,000 sq ft of new lawn seed; by our arithmetic, about 43.56 bales per acre (43,560 sq ft). This calculator is for pine straw mulch in beds, not for straw over new seed.

Pine straw questions

How many square feet does a bale of pine straw cover?

In seller figures read October 19, 2026, The Pine Straw Store lists 50 sq ft per box bale and 62.5 sq ft per pallet bale at 2 in depth, J&J Pine Needles lists 50 sq ft (range 45 to 55 sq ft) at 3 in depth, and Mid-Atlantic Pine Straw lists 40 sq ft at 2.5 in depth.

How many sq ft does a 2 cubic foot bag of mulch cover?

By volume geometry (1 cu ft equals 12 sq ft at 1 in depth), a 2 cu ft bag of mulch covers 12 sq ft at a 2 in depth or 8 sq ft at a 3 in depth. Use the mulch link in the calculation record below to size bagged or bulk bark.

How much is an acre of pine straw worth?

In forestry publication ANR-1418 (2019, read October 19, 2026), the Alabama Cooperative Extension System (ACES), citing Dickens et al., reports annual harvests of 150 to 275 bales per acre for loblolly pine, 125 to 250 for slash pine, and 80 to 200 for longleaf pine, and cites a UGA report listing landowner stumpage prices of $0.25 to $0.30 per bale for loblolly and $0.40 to $1.00 per bale for longleaf.

How many bales of straw does it take to cover 1 acre?

One acre is 43,560 sq ft (220 × 198 ft). For a 2 in settled pine straw bed (4 to 5 in fresh), that takes 697 pallet bales under the settled reading or 1,394 to 1,743 under the fresh reading (15, 30, or 37 pallets of 48 bales, totaling 720, 1,440, or 1,776 bales and 8,640, 17,280, or 21,312 lb), 872 to 2,178 box or Mid-Atlantic bales, or 581 to 1,452 J&J bales. For lawn seeding, Clemson HGIC 1203 gives 1 bale for about 1,000 sq ft; dividing the acre by that area gives our own estimate of about 43.56 bales.

Is this pine straw calculator free?

Yes. This calculator is free to use online with no registration, and you can print your order sheet or export an itemized CSV table directly from the results panel.

How heavy is a bale of pine straw?

On The Pine Straw Store’s product specifications (read October 19, 2026), a box bale weighs 9 lb (36 lb for a 4-bale box) and a pallet bale weighs 12 lb (576 lb for a 48-bale pallet). By comparison, Clemson HGIC 1203 notes that a cereal-grain seeding straw bale weighs 60 to 80 lb.

Does the estimate include pine straw delivery and installation?

No. This tool computes physical bale, box, and pallet quantities and published package weights only, without guessing local per-bale prices, shipping fees, or spreading labor.

Can I use this as a wheat straw coverage calculator?

No. This tool sizes pine straw mulch. For straw spread over new lawn seed, Clemson HGIC 1203 (updated 2024, read October 19, 2026) gives 1 bale (60 to 80 lb) for about 1,000 sq ft. For garden beds with another bale, select My seller’s own figure and enter your supplier’s coverage and depth.

How many bales of straw do I need to cover 1000 square feet?

For 1,000 sq ft (40 × 25 ft) at a 2 in settled depth (4 to 5 in fresh), you need 20 box or Mid-Atlantic bales under the settled reading or 40 to 50 under the fresh reading (5, 10, or 13 boxes of 4, which is 20, 40, or 52 bales weighing 180, 360, or 468 lb), 16 to 40 pallet bales, or 14 to 34 J&J bales. For lawn seeding, Clemson HGIC 1203 specifies 1 grain-straw bale per 1,000 sq ft.

How many bales of straw do I need for seeding?

Clemson Cooperative Extension’s Lawn Establishment guide (HGIC 1203, updated 2024, read October 19, 2026) states that 1 bale of cereal-grain straw weighing 60 to 80 lb covers about 1,000 sq ft over new lawn seed.

Where this estimate stops

  • Bale presets reflect the three sellers read on October 19, 2026; enter other bale sizes under My seller’s own figure.
  • The 2× to 2.5× settling band comes from one source, UGA CAES (2006).
  • Sellers do not say whether their stated depth is fresh or settled; both readings are shown.
  • Bed areas are plane geometry of the shapes entered; slopes and edging are not measured.
  • No bale prices, delivery fees, or spreading labor are estimated.
