35 x 35 x 35 in bulk bag
A 35 x 35 x 35 in bulk bag is the short size for dense product: its box volume of 24.8 cubic feet already holds about 2,480 lb of dry sand at an assumed 100 lb per cubic foot, so it is usually sewn at 2,000 to 2,500 lb SWL for sand, gravel and cement. It also suits fill lines with little headroom, and light batches of 800 to 1,200 lb that would leave a tall bag half empty.

Fill weight if filled to the box volume
Each row multiplies 24.8 cu ft by an assumed typical bulk density. A filled bag rounds out and settles, so the real fill differs: use your product's data sheet. Never fill past the SWL on the label.
| Product (assumed density) | Weight at 24.8 cu ft | Lightest common SWL that covers it |
|---|---|---|
| Plastic resin pellets (34 lb/cu ft) | 843 lb | 1,000 lb |
| Wheat flour (36 lb/cu ft) | 893 lb | 1,000 lb |
| Seed corn (45 lb/cu ft) | 1,116 lb | 1,500 lb |
| Granulated sugar (50 lb/cu ft) | 1,240 lb | 1,500 lb |
| Granular fertilizer (60 lb/cu ft) | 1,488 lb | 1,500 lb |
| Portland cement (90 lb/cu ft) | 2,232 lb | 2,500 lb |
| Gravel (95 lb/cu ft) | 2,356 lb | 2,500 lb |
| Dry sand (100 lb/cu ft) | 2,480 lb | 2,500 lb |

What fits in 24.8 cubic feet
The arithmetic is short. 35 x 35 x 35 in is 42,875 cubic inches; divide by 1,728 and the box holds 24.8 cubic feet, about 703 litres. That box is the ceiling, not the fill. An unbaffled bag rounds out as product goes in, its corners never pack square, and a free-flowing material leaves a cone under the top, so a real fill usually stops short of the box figure.
At the densities we assume for the tables, dry sand at 100 lb per cubic foot comes to 2,480 lb, gravel at 95 lb to 2,356 lb and portland cement at 90 lb to 2,232 lb. All three land between 2,000 and 2,500 lb, which is why this cube turns up so often in heavy, granular work. Plastic pellets at 34 lb only reach 843 lb, and granulated sugar at 50 lb about 1,240 lb. Your product's own data sheet decides the real number; ours are stated assumptions for the sum.
One rule outranks the arithmetic: the SWL on the label caps the fill, whatever room is left. A 2,000 lb bag of sand stops at 2,000 lb, which at 100 lb per cubic foot is 20 cubic feet, roughly four fifths of the box.
Where do these go? Landscape supply, masonry and play sand, foundry sand, crushed glass and sample lots of ore all move in short, heavy bags. Each is dense enough that a cube of fabric under three feet tall reaches its weight.
Short body, low fill head
A 35 in body stands just under three feet tall, and that matters at both ends of the job. At the filler, the loops hang on hooks or a bar while the inlet spout meets the filling head and the bag bottom rests on the scale or pallet; a short body leaves room on frames built low or tucked under a mezzanine. At the discharge station, the bag hangs from its loops over the hopper, and a short body keeps the drop and the frame height down.
Measure before you order. Take the distance from the scale deck or pallet top to the hook bar, then subtract body height, loop length and any top spout. If that number comes out small or negative for a taller bag, the 35 in cube is often what fits. A low, wide bag also carries its weight close to the forks, and the driver sees over it far more easily than over a 60 or 70 in bag.
Short bags suit jobsites as well. A landscape yard or a contractor often unloads with a telehandler or a rough-terrain forklift on gravel, and a squat, heavy bag swings less on uneven ground than a tall one. Angular stone, broken concrete and slag can cut the weave from inside, so for sharp product ask for heavier fabric or a coated body, and look each bag over for nicks before it goes under the chute.
Pallets, floor and payload
The 35 in square footprint leaves 2.5 in per side on a 40 x 40 in pallet, and 2.5 in by 6.5 in on a 48 x 40 in pallet, measured on the empty dimensions. A filled bag bulges past its nominal width, so those spare inches shrink once product is in; check the filled width before you rack or wrap it.
For trailer sums we assume a 53 ft dry van with 100 in of inside width and 630 in of length. Two bags fit across, since 100 / 35 = 2.86, and 630 / 35 gives 18 rows, so the floor takes 36 bags single stacked. With dense product the payload runs out first. At 2,480 lb of sand per bag, 44,000 / 2,480 = 17 bags, and half the floor rides empty. That is normal for aggregate and cement, and the carrier will want those 17 spread for axle weights. With 843 lb of pellets the picture flips: 36 x 843 = 30,348 lb, so the floor is full and the payload is not.
Stacking light, short bags two high is common in storage, but only when the bag is built and rated for it and the product holds its shape. Ask before you plan a load that way.
How it is usually built
Most of these go to aggregate yards, cement users and landscape suppliers, so the builds are plain and strong. Used bags come up for sand and gravel too; the used bulk bags page covers what qualifies, and the label still decides the fill.
Outdoors is where these bags tend to wait, and sunlight is hard on polypropylene. UV exposure softens the fabric surface until it powders, and a bag that has stood in prolonged sun should not be lifted; nor should anyone stitch up a torn loop and carry on. Keep empties baled under cover until the morning they are filled, and plan collection so full ones do not sit for weeks in an open yard.
- Duffle top or open top for sand and gravel loaded from a chute or a loader bucket
- Spout top and spout bottom for cement and other dusty powders run through a closed filler and discharger
- Flat bottom where the bag is cut open or tipped at the job
- Type A fabric for sand, gravel and cement where no flammable dust or vapour is present
- SWL of 2,000 to 2,500 lb, at a 5:1 single-trip safety factor for most aggregate work
Questions
How much does a 35 x 35 x 35 bulk bag hold?
The box volume is 24.8 cubic feet, about 703 litres. At our assumed densities that is 843 lb of plastic pellets, 1,488 lb of granular fertilizer or 2,480 lb of dry sand, but the SWL caps the fill, so a 2,000 lb bag stops at 2,000 lb even with room left.
Why order a short bag instead of a taller one?
Headroom and density. A heavy product reaches the rating long before it reaches the top of a tall bag, so the extra fabric does nothing, and a short body fits fill frames and dischargers that a 50 or 60 in bag will not clear.
How many full 35 x 35 x 35 bags go on a truck?
The floor of an assumed 53 ft van takes 36 single stacked, two across and 18 rows. With sand at 2,480 lb a bag, the 44,000 lb payload allows 17, so dense loads ship by weight, not by floor space.
