Which vans can you sleep across? Width between the walls, every base van
· 7 min read
Only one van family lets an average adult sleep across it without touching the walls: the Ducato, Boxer, Relay and ProMaster, at 1.87 m between the bare walls. Every other large van is 1.76–1.83 m, which sleeps a 1.70 m person at best; with wall flares the Crafter, Daily and Sprinter join, and no mid-size van does at all. That is the short answer. The long answer is a table, because the difference between “fits” and “knees bent” is four centimetres, and the brochure number is not the one you sleep in.
Why it matters: a transverse bed uses ~1.4 m of van length instead of the ~1.9 m a longitudinal one takes — half a metre of living space back, in the same van. It is the single biggest layout decision a body dimension makes for you, and the fixed-vs-convertible argument mostly depends on it. So before the bed style, check the width.
The rule
You need your height plus about 5 cm between the finished walls at mattress height — a pillow at one end and feet that are not pressed into a panel at the other. A typical wall build-up is 25 mm insulation plus a 5 mm panel per side, so finished width = bare width minus 6 cm. A 1.80 m sleeper therefore needs 1.85 m finished, or 1.91 m bare. No panel van is that wide between the walls, which is why the Ducato’s 1.87 m is the practical ceiling and everyone over 1.80 m ends up notching the panels or fitting flares.
The table: every base van, width between the walls
Bare widths are the between-walls figure from the van database that drives the planner (manufacturer width minus a per-platform offset calibrated against published cargo dimensions; it is the width above the wheel arches, not between them). Finished assumes the 6 cm build-up. Verdicts are for a 1.70, 1.80 and 1.90 m sleeper: ✓ = height + 5 cm or more, ~ = within 5 cm (notched panels, thin wall insulation at bed height, or a slight diagonal), ✗ = no. The last column adds 12 cm of wall flares.

What the table says
- The Ducato family is the transverse van, and even it is marginal at 1.80 m. 1.81 m finished against 1.85 m needed: the usual fix is to leave the panel out behind the pillow and at the feet, sleeping wall-to-wall on the insulation, which recovers 1–2 cm per side. Over 1.85 m tall, even the Ducato wants flares.
- The Crafter is the flare-friendly runner-up. At 1.83 m bare it is 4 cm short of the Ducato, and 12 cm of pods take a 1.80 m sleeper from no to yes with margin — the same pods on a Sprinter (1.79 m) land exactly on the line.
- The Daily is the overlooked one. 1.80 m between the walls is wider than a Sprinter, Transit or Master; a 1.70 m sleeper fits with notched panels and no cutting.
- Master, Transit, Sprinter: plan longitudinal unless you are short or willing to cut. 1.76–1.79 m bare is a 1.65–1.70 m sleeper. That is the honest reason so many Sprinter layouts run the bed down one side.
- No mid-size van sleeps an adult across it, flares or not. Transporter, Vito, Trafic and Expert are 1.63–1.70 m; the layouts for that class are in the small van guide.
When you are on the line
If your height puts you in a ~ cell, three things move it. Thinner wall insulation at bed height: 10 mm foam instead of 25 on the two strips the mattress touches buys 3 cm for almost nothing in warmth, because the bed covers them anyway. A slight diagonal: turning the mattress 5° across a 1.4 m-deep bed adds about 6 cm of length and costs nothing but a trapezoid cushion. Flares: window pods or bonded wall bulges add 5–8 cm per side and are the only route past 1.90 m in any van — budget the cost, the weight and a weatherproof bond, and check they clear the wheel arch and the rear door hinge.
Do not compare against your height in bare feet on a hard floor: a pillow, a 5 cm mattress compression and socks against a cold panel are why the rule carries the 5 cm.
Width is the first cut, height is the second
Width decides whether the bed goes across; the roof then decides whether you stand next to it — the standing-height table is the companion to this one, and the full dimensions comparison has both per variant. In the planner, the transverse bed template is placed against the real wall taper of the van you pick, so a ~ verdict shows up as a bed that touches the panel before you cut one.
FAQ
Can you sleep across a Sprinter?
Not as an average adult without modifying the walls. A Sprinter is 1.79 m between the bare walls, about 1.73 m after insulation and panels. That fits a 1.65 m sleeper; a 1.80 m person needs about 1.85 m. With window pods or wall flares that add 12 cm it becomes 1.85 m — a 1.80 m sleeper fits, a 1.90 m one does not.
Which vans fit a transverse bed without wall flares?
One family: the Fiat Ducato, Peugeot Boxer, Citroën Relay/Jumper and RAM ProMaster, at 1.87 m between the walls (about 1.81 m finished). That sleeps a 1.75 m person with room and a 1.80 m person with the panels notched at head and feet. The Iveco Daily (1.80 m bare, 1.74 m finished) is the only other large van within reach, and only for sleepers up to about 1.70 m.
How much width do you need to sleep across a van?
Your height plus about 5 cm, measured between the finished walls at mattress height. A 1.80 m sleeper therefore needs 1.85 m finished, which is 1.91 m bare once you take off a 25 mm insulation layer and a 5 mm panel on each side. No production panel van is that wide between the walls, which is why the Ducato's 1.87 m is treated as the limit.
What do wall flares or window pods add?
Typically 5–8 cm per side, so 10–16 cm of sleeping length. They replace the rear quarter windows or cut into the wall skin, cost money and weight, and need a clean weatherproof bond. On a Crafter (1.83 m bare) they turn a no into a yes for a 1.80 m sleeper; on a Master (1.76 m) they get you to about 1.82 m — still short for 1.80 m.
