Short answer: there is no single number — loading depends entirely on the carton volume of the model you buy. In KREEDA’s 2026 range, the lightest walking pad loads 340 units per 20GP while a full-size office treadmill loads 106. The table below gives the measured figure for 18 representative models, and the formula further down lets you check any model against its carton dimensions before you commit to an order quantity.
Why “how many fit in a container” has no single answer
A container is a fixed box; a treadmill carton is not. Two models with the same belt size can differ by 30% in loading because one folds flatter or ships in a two-piece carton. Loading is set by four things: the folded thickness of the deck, whether the handrail is detachable, the carton’s internal padding, and whether the cartons stack two-high inside the container. Only the factory’s loading test — not a rule of thumb — produces the real figure.
Container reference figures
| Container | Internal volume (approx.) | Typical use |
|---|---|---|
| 20 ft standard (20GP) | ≈ 33 CBM | Dense, heavy cargo; the practical choice for a first trial order |
| 40 ft standard (40GP) | ≈ 67 CBM | Volume cargo where weight is not the limit |
| 40 ft high cube (40HQ) | ≈ 76 CBM | Tallest cartons; usually the lowest freight cost per unit |
Those interior volumes are the industry-standard approximations used for freight planning (see this container planning guide). Treat them as planning figures, not as a promise from the shipping line: the usable volume is always a little less than the nominal volume, because cartons do not fill the last five centimetres of any container.

| Model | Category | Running surface | 20GP | 40GP | 40HQ |
|---|---|---|---|---|---|
| Q29-2 | Walking pad | 375 × 900 mm | 340 | 686 | 806 |
| Q20 | Walking pad | 420 × 1050 mm | 218 | 458 | 530 |
| Z06 | Walking pad | 400 × 900 mm | 222 | 450 | 528 |
| JK31-9 | Walking pad | 400 × 1050 mm | 183 | 379 | 430 |
| Z10 | Walking pad | 430 × 1050 mm | 198 | 410 | 476 |
| S32-9P | Walking pad | 410 × 1050 mm | 198 | 407 | 472 |
| JK31-8 | Running & walking | 400 × 1050 mm | 178 | 366 | 413 |
| JK8866-1 | Running & walking | 460 × 1100 mm | 156 | 312 | 360 |
| JK68-1 | Office treadmill | 420 × 1200 mm | 115 | 244 | 266 |
| JK68-6 | Office treadmill | 420 × 1000 mm | 138 | 277 | 304 |
| JK68N | Office treadmill | 420 × 1200 mm | 106 | 219 | 243 |
| JK360F-1 | Foldable treadmill | 360 × 1000 mm | 114 | 243 | 275 |
| Q24-10 | Foldable treadmill | 360 × 950 mm | 247 | 509 | 618 |
| Q30-6 | Foldable treadmill | 375 × 930 mm | 246 | 544 | 632 |
| JK1608N-6 | Foldable treadmill | 390 × 1000 mm | 168 | 381 | 404 |
| JK1601 | Foldable treadmill | 400 × 1050 mm | 168 | 351 | 405 |
| JK43-1 | Foldable treadmill | 430 × 1050 mm | 132 | 270 | 294 |
| JK1608N | Foldable treadmill | 390 × 1000 mm | 142 | 307 | 351 |
Two things follow immediately from the table. First, the spread within one category is larger than the spread between categories — Q29-2 loads three times as many units as JK68N, and both are legitimate products for different markets. Second, the jump from 20GP to 40HQ is not linear: it is roughly 2.3× on most walking pads but closer to 2.1× on the bulky office units, because the cartons on the bulky models cannot be stacked as efficiently.
How to work out loading for a model that is not in the table
Ask the factory for the carton dimensions and the gross weight, then:
units per container ≈ (container volume × packing efficiency) ÷ carton volume
Use 0.85–0.90 as packing efficiency for flat treadmill cartons, and check the result against the container’s payload limit — a 20GP is usually capped around 25–28 tonnes of cargo, which for a 30 kg gross carton works out at roughly 830 units, well above what the volume allows. On walking pads, volume binds first. On heavy commercial units, weight can bind first, and it is worth asking which limit your order hits.
Why 40HQ is usually — but not always — the cheapest per unit
Freight is charged per container, so a bigger container spreads the same cost over more units. But three things can flip that conclusion: a supplier whose cartons are too tall for a 40HQ’s door opening (rare, but it happens with assembled handrails), a destination port where 40HQ equipment is scarce, and an order small enough that you cannot fill a 40HQ and would pay for air. For a first order, a 20GP of a fast-moving walking pad is often the right unit of risk — and it is also the fastest way to get real data on how the product actually performs in your market.
Frequently asked questions
How many treadmills fit in a 20 ft container?
Between roughly 106 and 340 units in KREEDA’s 2026 range, depending on the model. The low end is a full-size office treadmill; the high end is a thin walking pad. The figure for your exact model is on its specification table.
How many walking pads fit in a 40HQ?
On the models above, 401 to 806. The Q29-2 reaches 806 units per 40HQ, which is the highest figure in the range.
Should I order a 20GP or a 40HQ for a first shipment?
Order the container you can sell through. A 20GP reduces the cash tied up in stock and gives you a faster read on demand; a 40HQ lowers freight per unit but only helps if the stock moves. Many first orders are a mixed 20GP with two or three models.
Can I mix models in one container?
Yes, and it is usually the better first order. Give the factory the quantity per model and it will calculate the loading for the mix. Mixing costs a little volume efficiency but it de-risks the order considerably.
Does the loading figure include pallets?
Not on these models. The figures above are floor-loaded cartons. If your market requires palletised delivery, ask for the palletised loading figure as well — it is typically 15–25% lower.
Why do two suppliers quote different loading numbers for the same carton size?
Because one of them is quoting a calculation and the other is quoting a test. Ask for the loading test photograph or the container loading plan. KREEDA publishes the tested figure on each model’s specification table.
Does the 40GP or 40HQ figure include the weight limit?
These figures are volume-limited on the models shown. On the heaviest office units a 40HQ can approach its payload limit before it runs out of volume, so confirm both when the order value is large.
