Which van size do you actually need?

• The longest single item. A sofa, a ladder, a pallet, a rolled carpet. Nothing else matters as much as this one number.
• How high you can stack. Boxes stack; furniture does not. If your load will not stack, you need floor length, not volume.
• Whether it goes in flat or upright. A mattress that has to lie flat needs the full load length even though it weighs nothing.
• Only then, the weight. If you are moving tiles, cement, water or equipment, check the payload column as well.

Take a one-bedroom flat with the usual contents: a two-seat sofa, a bed with a slatted base, a wardrobe that comes apart, a dining table with four chairs, a fridge, a washing machine, a television and somewhere between thirty and fifty boxes. Nobody can eyeball that and name a van. Broken into three numbers, anybody can.

First number: the longest single item. Here it is the sofa or the bed base, call it 2.0 m. That rules out nothing on the ladder, so length is not the constraint, which is already useful to know.

Second number: how much of it will stack. Boxes stack to the roof; the fridge, the washing machine and the sofa do not. Count the floor those unstackable items need, side by side, and you have the floor length that must stay clear. For this flat it is roughly 2.5 m of floor with everything else going above and around it.

Third number: whether anything must travel upright. A fridge usually must. That turns a height figure from a nice-to-have into a requirement, and on this list it is what pushes the answer from the shorter vans to a Transit or a Urvan rather than the smallest thing that would technically hold the volume.

Three numbers, and the flat above is a Transit in one trip or a Hiace in two. Notice that the weight never came into it. Unless you are moving something dense, the payload column is the last thing you check, not the first.

The same three numbers work for a shop fit-out, a site delivery or an office move. What changes is which of them binds: on a site delivery it is usually weight, on an office move it is usually the number of unstackable items, and on a flat move it is almost always the one tall thing nobody thought to measure.

Towers are the common one. Most buildings in Dubai want moves through a service lift rather than the main lobby, and the service lift usually has to be booked, sometimes days ahead, often with a security deposit and a certificate of insurance from whoever is doing the move. The lift car also has its own internal dimensions, and they are frequently tighter than the van.

Loading bays come with time limits and with a height barrier at the ramp. A vehicle that clears the barrier can still be turned away if the bay is booked, and a vehicle that does not clear it has to unload at street level and trolley everything in, which changes the job from a two-hour one into a half-day one.

Villa communities have their own version: a gate with a guard, a list your vehicle has to be on, and in some communities a working-hours window outside which no move is allowed at all. None of this is difficult, but all of it has to be arranged before the van arrives rather than while it idles at the barrier.

Then there is the route inside: the flat door, the corridor turn, the stairwell if the lift is out. Measure the tightest point on that route, not the widest, and measure it before you choose the van rather than after.

Send us the delivery address with the booking. We will say plainly whether the vehicle you want can reach it, and if it cannot, which one can.

Access at the pickup end deserves the same five minutes. A ground-floor villa with a driveway loads in a fraction of the time a fourth-floor flat with one lift does, and if both ends are awkward the job is longer than the distance suggests. That is worth knowing before you book a single day rather than after.
