Truck Loading Calculator

It depends on your box size, how the boxes can be turned and whether they stack. The 26 ft box truck preset uses inside dimensions of 789 × 246 × 246 cm with a 4,535 kg (10,000 lb) payload. Enter your box dimensions, weight and quantity, and the calculator places them in 3D and tells you how many fit and whether space or weight runs out first. Inside height on these trucks ranges from about 8 ft 1 in to 8 ft 7 in, which can change how many layers fit, so measure the truck you’re renting if the load is tight.

On the floor, a 53' dry van takes 26 standard 48 × 40 in (GMA) pallets loaded straight and 30 loaded turned. The Trailer Load Calculator shows both patterns from a top view. This calculator goes further: it uses the full cargo space of 1,600 × 250 × 279 cm (the same 630 × 98.5 × 110 in, rounded down) and the 20,411 kg (45,000 lb) payload, so it shows whether your pallets can be double-stacked and whether weight runs out before space does. Mark pallets that can’t carry weight as Non-stackable.

No. Each preset uses the inside dimensions of one representative published spec for that truck class, rounded down to whole centimeters. Real trucks differ by a few centimeters between manufacturers, bodies and model years, and inside height can differ by tens of centimeters, for example between low-floor and high-floor bodies. Height decides how many layers fit, so it matters most. When you know the cargo space of the truck you’ve booked, enter it as custom dimensions and use the presets for early planning.

No. The calculator checks that the cargo fits inside the cargo space and stays within the truck’s payload. It doesn’t check axle loads, front-to-rear weight distribution, load securing or the gross vehicle weight allowed on the road. The presets have no tare weight, so it can’t estimate the gross weight of the loaded truck either. Plan straps, load bars and axle weights with your carrier and confirm the load against the rules on your route.

Wing bodies and curtainsiders are loaded from the side, so a rear door opening like a shipping container’s doesn’t limit what goes in. For vans, box trucks, dry vans and reefers, the presets don’t include door dimensions, so no door check runs on those either. If you load through the rear doors, check that your largest item clears the opening and any lift gate, or pick Custom and enter the door size so the calculator checks it.

The Trailer Load Calculator counts pallets on the floor of a US trailer: footprint only, straight or turned, single or double stacked. The truck loading calculator places boxes and pallets in three dimensions, using height, weight, rotation and stacking rules for each item, and it covers trucks in Japan, Korea and Europe as well as the US. Use the Trailer Load Calculator for a quick pallet count and this one when box sizes, mixed items or weight decide the load.

In Japan, the class name isn’t the payload. A 4t wing truck carries about 2.8 t, an uprated 4t (zōton) wing 7.3 t and a large 10t wing 13.5 t, and the presets use the maximum payload from the source spec. In Korea, the class name roughly matches the nominal payload: a 1-ton truck carries 1,000 kg and a 5-ton truck 5,000 kg. The 11-ton preset uses 13,000 kg from its source, and the 2.5-ton and 3.5-ton presets use the class value. In Europe, a curtainsider semi-trailer is usually quoted at 33–34 EUR pallets.

Each of these vehicles has two separate load spaces, and the calculator fills them one at a time: the lower deck first, then the upper deck on the UK double-deck trailer, and the truck body first, then the trailer body on the drawbar combination (Gliederzug). Each section gets its own results tab, and the 3D view shows the whole vehicle with the deck floor or partition drawn in. Freight never stacks through a deck. Both sections share one payload: 24,000 kg assumed for the double-deck trailer and 21,700 kg calculated for the drawbar combination. If the first section uses up the weight, nothing more goes into the second. The calculator doesn’t optimize how weight is split between decks or bodies. These vehicles aren’t part of Auto (best fit) and can’t be split across several trucks, so they’re calculated only when you pick them. The double-deck trailer’s length, width and payload are assumptions based on a 13.6 m semi-trailer, and its 187 cm deck height is one builder’s inside opening for a fixed deck. Real deck heights run from about 150 to 197 cm depending on the deck type (fixed or moving), wheel size and position along the trailer, with less height over the front swan neck, so measure the trailer you’re booking.

Insulation takes up space, so a refrigerated truck or reefer trailer has smaller inside dimensions than a dry truck of the same class. The Japanese 4t wing preset is 627 × 222 × 242 cm, while the 4t reefer is 620 × 211 × 212 cm. In the US, the 53' dry van is 1,600 × 250 × 279 cm and the 53' reefer 1,569 × 246 × 262 cm. The presets don’t allow for the refrigeration unit or air ducts, so measure the reefer you’re booking and enter it as custom dimensions.
