Cargo Van Load Calculator
Work out the smallest UK hire-van size that fits your load — checked by volume, weight, longest single item, and whether you need a tail lift.
Calculator Inputs
Rough guide: a 3-seat sofa is about 1.5-2 m³, a 1-bed flat move is typically 12-18 m³, a 3-bed house move is typically 30-45 m³.

Which UK Van Size Do You Actually Need?
UK hire companies commonly group vans into five size classes: small (around 3 m³), medium/SWB (around 5 m³), large/LWB (around 9 m³), Luton (around 17 m³), and 7.5-tonne box lorries (around 30 m³), cross-checked across MyJobQuote's UK van sizes guide and SDVH's Luton van capacity guide. The right class depends on volume and weight together — a load can be light but bulky (favouring more volume) or heavy but compact (favouring more payload), which is why this calculator checks both rather than just one.
Why Long Items Need Their Own Check
A medium van's load bay is typically only about 2.4m long, according to Parkers' Ford Transit Custom dimensions guide, and a large van's is around 3.0m — both too short for a 3.4m wardrobe, sofa bed or ladder, even when the total volume would easily fit. This calculator checks your longest single item's length against each class's load bay separately from the volume total, which a simple "total cubic metres" calculator misses entirely.
The Luton Payload Trade-Off
A 3.5-tonne Luton van's payload is often lower than a large panel van's — commonly 900-1,200 kg against a large van's up to 1,200 kg — despite having roughly double the load volume, because the Luton's bigger box body is itself heavier and both vehicles are capped at the same 3.5-tonne gross weight, per SDVH's Luton van capacity guide. For bulky-but-light loads (bedding, boxes, flat-pack furniture) this trade-off usually still favours the Luton; for dense, heavy loads (books, tools, building materials), the payload figure can matter more than the extra volume.
What Licence Do You Need?
A standard category B (car) licence covers every van class up to 3.5 tonnes maximum authorised mass — small, medium, large and Luton vans all included. Driving a 7.5-tonne box lorry needs category C1, which is automatic only for drivers who passed their car test before 1 January 1997; anyone who passed after that date needs a separate C1 test, according to GOV.UK's guide to driving licence categories.
Common Mistakes When Choosing A Van Size
The most common mistake is checking volume alone and forgetting weight — a load of heavy items (books, tiles, tools) can hit a smaller class's payload limit long before it fills the available volume. The second most common mistake is forgetting a single long item's length entirely, only to find it doesn't fit the load bay on the day. The third is assuming a bigger van always means more weight capacity, which the Luton payload trade-off above shows isn't always true.
Method And Limits
This calculator works from class-level representative figures for five common UK hire-van size classes, not the exact specification of any specific vehicle you'll be offered.
- Does not model 3D packing — it checks total volume, total weight, and your longest item's length as three separate pass/fail checks, not whether an odd mix of shapes actually tessellates into the load bay. Add a safety margin to your volume estimate for a complex mixed load.
- Does not model the exact model or trim you'll actually be offered — real vehicles vary meaningfully from these class averages, so confirm the payload plate and internal dimensions of the specific van you book.
- Does not model roof racks, roof boxes, or towing — these change the effective capacity calculation entirely and aren't covered here.
- Does not model multi-drop or route planning — this is a single-trip sizing tool, not a logistics planner.
- Uses conservative, lower-end figures for every class deliberately, so an "it fits" result is a safe planning figure rather than an optimistic best case.

Frequently Asked Questions
What size van do I need for a house move?
It depends mainly on total volume, not the number of rooms. A typical 1-bed flat move is roughly 12-18 m³ (fits a large van, sometimes a Luton for extra headroom), while a 3-bed house move is typically 30-45 m³, which usually needs a Luton van or a 7.5-tonne box lorry, sometimes across two trips.
How much does a small van typically carry?
A small van (e.g. Ford Transit Connect, VW Caddy, Vauxhall Combo class) has a typical load volume of around 3 m³ and a payload of around 700 kg on the conservative end of the published range — enough for a small flat-share move, but not a full house move.
Why would a long item need a bigger van than my total volume suggests?
Because van load bays have a fixed length as well as a fixed volume. A medium van's load bay is typically only about 2.4m long and a large van's about 3.0m, so a single item longer than that won't fit even if your total volume is small enough for a smaller class.
Why does a Luton van sometimes have a lower payload than a large panel van?
Because a Luton's payload is capped by the same 3.5-tonne gross vehicle weight as a large panel van, but its bigger box body is itself heavier, leaving less of that allowance free for your actual load. A large panel van's payload can be around 1,200 kg while a comparable Luton's is often closer to 900-1,200 kg, even though the Luton has roughly double the load volume.
Do I need a special licence to drive a hire van?
For any van up to 3.5 tonnes maximum authorised mass, a normal category B (car) driving licence is enough. A 7.5-tonne box lorry needs category C1, which UK drivers who passed their car test before 1 January 1997 hold automatically; everyone else needs to pass a separate C1 test.
What's the difference between a Luton van and a large panel van?
A large panel van has a load bay integrated into the vehicle's normal body shape. A Luton van has a separate, taller, squarer box body built over the cab, giving significantly more load volume — typically 17 m³ or more against a large panel van's 9-13 m³ — in exchange for often having a lower payload.
How is a tail lift useful, and which van classes offer one?
A tail lift is a powered platform at the rear of the van that lowers to ground level, letting you wheel or slide heavy or awkward items in without lifting them up. They're commonly available on large vans, Luton vans and 7.5-tonne box lorries, but rarely offered on small or medium vans.
Can I fit a 3-bed house move in one van, or will I need multiple trips?
A typical 3-bed house move (roughly 30-45 m³) is right at or beyond the largest single hire-van class this calculator covers, so it's common to need either the largest available box lorry with careful loading, or two trips in a Luton van.
Does this calculator account for the weight of packing materials, boxes or blankets?
Not automatically — the weight input is your total load weight, so include a reasonable allowance for boxes, packing materials and moving blankets if you're estimating rather than weighing your actual items. Adding 5-10% to your best-guess item weight for packaging is a sensible margin.
What if my exact load volume or weight is hard to estimate?
Use the rough guides shown next to the volume input as a starting point, and round up rather than down — this calculator already uses conservative, lower-end figures for each van class, so a slightly generous estimate on your side keeps the safety margin intact.
Is this the same as a professional freight or container load calculator?
No. Freight and container load calculators typically do full 3D bin-packing across pallets, crates or containers for commercial cargo. This tool is aimed at someone hiring a domestic or small-business van and deciding which UK hire-van size class to book.
Will my furniture actually fit through the van doors, not just the load bay?
This calculator checks your longest single item against each class's load bay length, but van rear-door openings and side-door widths vary by model and aren't checked here — always measure your largest single item's width and height and check the specific van's door dimensions with your hire company.
