If you are working to a clearance or a floor-loading limit, put the number in the message field and we will check it against the actual units.
Nearly every IBC tote shares a 48 × 40 inch footprint. Height, tare weight and valve thread are what actually vary — and those three are what cause every specification problem we see. A 275 gallon unit is 46 in tall and 125 lb empty; a 330 is 53 in and 143 lb; a 550 is 64 in and 265 lb. Work to a half-inch of tolerance in either direction.
Start with the constraint, not the capacity
People choose tote size by volume and then discover a dimension problem. It is faster the other way round. Identify your binding constraint first:
- Floor area? Go taller. A 330 gives you 20% more volume in exactly the same footprint as a 275.
- Overhead clearance or a doorway? Go 275, and remember to add four to six inches for the forks.
- Lift capacity? A filled 275 is 2,420 lb and a filled 550 is 4,860 lb — the latter needs a 6,000 lb truck, not a 5,000 lb one.
- Floor loading? 2,420 lb over 13.3 sq ft is about 182 lb per square foot. Mezzanines and older timber floors frequently cannot take that stacked two high.
- Gravity feed height? That is a stand question, not a tote question. See fabrication.

Fill height to gallons to shipped weight
Drag the fill level and the tool answers all three questions at once, including how many fit on a legal load.
Net product weight 2,295 lb. Gallon and litre figures assume a straight-walled bottle; the real bottle tapers at the shoulder, so treat anything above 95% as nominal and always leave headspace for thermal expansion.
Size questions
What are the standard IBC tote dimensions?
The standard 275 gallon unit is 48 × 40 × 46 inches on a 48 × 40 inch pallet footprint. A 330 gallon unit shares the same footprint and stands about 53 inches tall. A 550 gallon unit is larger in every direction at roughly 62 × 48 × 64 inches. The 48 × 40 footprint is not an accident — it is the standard North American GMA pallet, which is why totes palletise, rack and truck so efficiently.
Why do two 275 gallon totes measure slightly differently?
Pallet construction and manufacturer. A steel-pallet unit typically runs 45.5–46.5 inches tall; a composite or all-plastic base can be half an inch either side of that. Bottle moulds also differ slightly between manufacturers. If you are fitting totes under a fixed clearance — a dock door, a mezzanine, a pump-over gantry — work to 47 inches for a 275 and 54 for a 330 and you will never be caught out.
How tall is a tote on a forklift?
Add your fork height. A standard carriage lifts the pallet base about 4–6 inches to clear, which puts the top of a 275 gallon unit at roughly 50–52 inches in transit and a 330 at 57–59. The common failure is a 56-inch doorway and a 330 gallon tote, which fits standing and does not fit moving.
Is the 275 gallon capacity actual or nominal?
Nominal. A '275 gallon' tote is really a 1,000 litre tote, which is 264.2 US gallons, and the usable brim capacity is closer to 288 gallons because the bottle is taller than the nominal fill line. Never plan to use brim capacity: liquids expand, caps need headspace, and a tote filled to the shoulder will push product out of the vent on a warm afternoon.
Every format, every dimension
Nominal names are marketing; the litre figure is the real design volume. Specify in litres whenever it matters.

The one dimension that never varies
48 × 40 inches — the GMA pallet, the dominant North American pallet standard. By adopting it the IBC inherits, free of charge: every pallet rack beam in the country, every forklift fork spacing, 26 floor positions in a 53-foot trailer, standard dock-leveller geometry, and the ability to go through a 48-inch doorway turned sideways.
It is also why oversize units are disproportionately awkward. The moment you leave 48 × 40, you leave all of that behind at once.

What to work to, so nothing surprises you
Catalogue dimensions are nominal. Design to the top of each range and you will never be caught out.
| Measurement | 275 gal | 330 gal | 550 gal |
|---|---|---|---|
| Height, standing — design to | 47 in | 54 in | 65 in |
| Height, on forks in transit | 53 in | 60 in | 71 in |
| Width — design to | 48.5 in | 48.5 in | 62.5 in |
| Depth — design to | 40.5 in | 40.5 in | 48.5 in |
| Discharge centreline above floor | 9.5 in | 9.5 in | 11 in |
| Fill cap centre above floor | 46 in | 53 in | 64 in |
| Two filled units stacked | 92 in | 106 in | Do not stack |
| Four empty units stacked | 184 in | 212 in | Do not stack 4 |
| Minimum forklift capacity, filled water | 5,000 lb | 5,000 lb + margin | 6,000 lb |
| Minimum forklift, filled SG 1.4 | 5,000 lb + margin | 6,000 lb | 8,000 lb |
Dimensional tolerance you should expect
- Footprint: 48 × 40 in, ±0.25 in. Effectively fixed.
- Height, 275 gal: 45.5 – 46.75 in depending on pallet base and bottle mould.
- Height, 330 gal: 52.5 – 53.75 in.
- Tare, 275 gal: 118 – 132 lb, again by pallet type.
- Discharge centreline: 7 – 9.5 in. The figure that catches out anyone building a drain pan or a catch tray.
Choose by what binds, not by capacity
People choose tote size by volume and then discover a dimension problem. It is faster the other way round. Identify the binding constraint first.
| If this binds | Choose | Why |
|---|---|---|
| Floor area | 330 gal | 25% more volume in exactly the same 13.33 sq ft |
| Overhead clearance or a doorway | 275 gal | Seven inches lower standing, and the forks add four to six more |
| Forklift capacity | 275 gal | 2,330 lb filled with water against 2,900 for a 330 |
| Floor loading | 275 gal, single tier | 175 lb/sq ft against 218 for a 330, and 350 stacked |
| Visual level checks from the floor | 275 gal | You cannot see into a 330's opening standing up |
| Gravity feed head pressure | 330 gal, or a stand | Height is free head pressure if you are feeding downhill |
| Sprinkler clearance when stacked | 275 gal | Two filled 330s reach 106 in |
| Batch integrity — cannot be split | 550 gal | The only reason oversize is ever correct |
| Freight per gallon | 330 gal | 26 positions either way, so more volume per truck |
| No forklift available at all | Drums | 480 lb filled against 2,330 |
Why 275 became the standard
Three constraints converged. 1,000 litres is a round metric number and the format was designed in Europe. A 48 × 40 inch footprint is the North American pallet standard, so the container inherits all the existing handling infrastructure. And at 46 inches it clears a standard dock door even on forks, and is low enough that a person can see into the top opening while standing on the floor.
That last point matters more than it sounds. Plants with frequent visual fill checks stay on 275s even when floor space is tight.
Detailed questions
Why is a 275 gallon tote only 264 gallons?
Because it is a 1,000 litre tote and 1,000 litres is 264.172 US gallons. The nominal name is a rounded-up marketing figure. Brim capacity is nearer 288 gallons but you should never plan on it: thermal expansion of water alone is three-quarters of a gallon between 60 and 100 °F, and hydrocarbons are three to four times that.
Can I mix 275 and 330 gallon units in the same rack or stack?
Rack, yes — same footprint, same beam spacing. Stack, no: a 330 on a 275 does not interlock, the load path is wrong, and the combined height is awkward. Keep stacks to a single format.
What is the smallest IBC format available?
120 gallon, which is 450 litres at 40 × 32 × 39 inches and 78 lb tare. It is pallet-jack friendly on smooth concrete and genuinely useful where a full 275 will not fit or cannot be lifted. Availability is intermittent because few shippers use them.
Do all totes have four-way forklift entry?
Steel and composite bases, almost always. All-plastic bases are frequently two-way only, which in a tight aisle or a packed trailer turns a thirty-second pick into a five-minute shuffle. If you are specifying a fleet this is worth more than the four pounds of tare you save.
How accurate is a dipstick measurement?
Two to three percent through the straight-walled middle band — about 4 to 40 inches on a 275. Near the base and the shoulder the bottle tapers and a linear estimate overstates. For custody transfer you need a flow meter or a scale; for process control a dipstick or an external sight tube is fine.
What does a tote weigh empty if I need to ship it back?
118 to 132 lb for a 275 and 136 to 152 lb for a 330, depending on pallet base. That is the number a carrier bills on for an empty return, and it is why empties are cube-bound rather than weight-bound: 48 of them is only 6,000 lb against a 43,500 lb payload.
Is there a standard for IBC dimensions?
Not a single dimensional standard, no. What is standardised is the UN packaging code — 31HA1 for a composite IBC for liquids — which specifies test performance rather than geometry, and the GMA pallet footprint, which is a de facto commercial standard. Everything else is manufacturer convention, which is exactly why heights vary by an inch.
Can you measure a specific unit for me before shipping?
Yes. If you are working to a fixed clearance, a gantry height or a bunded area, tell us the number and we will measure actual staged units with a tape rather than quote a catalogue figure. It takes a grader two minutes and it has saved several customers a wasted delivery.
