How to Choose a Campervan: Find the Right Van Size for You
Our first campervan was a 2015 Renault Trafic. It had no standing height, and Jacob could barely sit fully upright on the bed. From the outside, it did not look like the spacious vanlife builds we had been watching online, and there were certainly moments when an extra half-metre of interior space would have been welcome.
Once we started travelling, however, the smaller size became one of the van’s greatest strengths. We could drive through cities, fit into ordinary car parks and use it much more like an everyday vehicle. Inside, we still had a comfortable bed, a simple kitchen and enough storage for our trips around Europe. It was not perfect, but it worked well enough to get us out of the driveway and onto the road.
That experience still shapes the way we think about campervans. When people ask us how to choose a campervan, our first advice is not to buy the largest van they can afford. It is to choose the smallest van that still works for the people, journeys and weather they are actually planning for.
Quick answer: What size campervan should you choose?
For one or two people, a small or medium-sized van is often enough, particularly for weekend trips, summer holidays and travel where most of the day is spent outdoors. A larger high-roof van becomes more valuable when you want to stand inside, travel for longer periods or use the van throughout autumn and winter.
For four people, the decision becomes more complicated. A medium van can work for two adults and two younger children on shorter trips, especially with a pop-top or another flexible sleeping arrangement. For older children, four adults or longer journeys, a large high-roof van is normally easier to live with.
For five people or more, the number of suitable travel seats and the available payload should be checked before you begin planning beds or furniture. At that point, a large panel van, minibus or ready-built motorhome may be more practical than trying to adapt a standard van conversion.
Our CamperPals rule is simple:
Choose the smallest campervan that still gives everyone a suitable place to travel, a comfortable place to sleep, enough storage and an interior that remains usable when the weather keeps you inside.
By the end of this guide, you should be able to choose between a small, medium and large campervan based on the number of travellers, your travel style, comfort expectations and total budget.

4 Key Questions Before You Choose Your Base Vehicle
What’s your actual goal with vanlife?
Before you fall in love with a listing, get clear on what you’re building for. Are you chasing spontaneous weekends in the woods, or a six-month road trip across Europe? Your goal affects everything: the van size, the layout, how much power you’ll need, even how many solar panels make sense on the roof.
A helpful first step is to write down your must-haves and nice-to-haves:
- What do you want in your conversion?
- What can you live without?
- How much space will your essentials take?
If you want a structured base for this, use a simple checklist like a Van Conversion Map (rooms/zones, storage, electrics, water, sleeping, work space).t
Quick tips to avoid common buying mistakes
Buying a campervan base vehicle is like choosing a travel partner: you want someone reliable, not just good-looking.
A few quick “save-your-future-self” tips:
- The cheaper the van, the more you need to budget for repairs and downtime
- Don’t buy on vibes. Buy on fit + condition
- Don’t assume you can “fix it later” if the base vehicle is the wrong size
What type of van fits you best?
Do you want a comfortable “mini-motorhome” with all the features, or are you more of a minimalist who’s happy with the essentials?
This matters because your base vehicle sets your limits:
- Standing height
- Bed orientation (lengthways vs sideways)
- Bathroom options (or no bathroom)
- Storage volume
- Stealth vs obvious camper look
We’ll guide you through the main van options, but you’ll get a better result if you decide early whether you’re building:
- A full-time live-in van, or
- A stealthy city-friendly weekend van, or
- A family / long-distance road trip van
Activate your inner car dealer
Prepare to ask questions, negotiate calmly, and walk away if something feels off. Most beginners lose money here, not because they’re bad at bargaining, but because they get emotionally attached too early.
You don’t need to be aggressive, you just need to be prepared.
Start with the journey, not the badge on the bonnet
A van used for summer weekends has a fairly simple job. It needs to transport you, carry your equipment and provide a comfortable place to sleep. A van used for several months at a time needs to do much more. It may also need to work as a kitchen, office, changing room and living space during several days of rain.
Before comparing brands, think about how many people will travel, how long you expect to be away and how much time you will spend inside. Consider whether the van must fit into normal car parks. You see a Sprinter conversion with a fixed bed and shower, then a compact Transporter with a pop-top, and suddenly both seem like sensible choices. The problem is that they are designed for very different types of travel. It is tempting to start searching for a Sprinter, Ducato, Transporter or Trafic before deciding what the vehicle needs to do.
The useful question is therefore not, “Which campervan is best?” It is, “Which campervan is best for the way we intend to travel?”
Begin with a few simpler questions:
- How many people need to travel and sleep in the van?
- Will you use it for weekends, holidays or several months at a time?
- Will you mainly travel in summer or throughout the year?
- Do you need full standing height?
- Would you prefer a fixed bed, or are you happy to make the bed each evening?
- Do you need space for bikes, a pushchair, surfboards or other large equipment?
- Will the van also be used as an everyday vehicle?
- How much money must remain for servicing, repairs and the conversion itself?
- How much time are you likely to spend inside during wet or cold weather?
Your answers will usually eliminate several attractive but unsuitable vans before you spend hours comparing engines and trim levels.
How many people must the campervan work for?
The number of travellers affects much more than the size of the bed. Every additional person needs a suitable travel seat, somewhere to sleep, personal storage and a share of the available payload.
In UK campervan adverts, you will often see terms such as two-berth and four-berth. A berth normally describes sleeping capacity. It does not automatically mean that the vehicle has the same number of suitable travel seats, which is particularly important when children or additional passengers will be travelling with you.
Stealth mode: Blend in inside cities
If you spend time in cities, maybe you even work a normal job and just travel on weekends, a stealth campervan can be a real advantage.
For our first Europe trip we chose a Renault Trafic specifically to park discreetly in cities. A more subtle van can:
- Reduce attention
- Make overnight parking easier
- Lower the risk of being moved on by locals/police
But here’s the downside we learned the hard way: a stealth campervan can also look like a trades van, the kind people assume is full of tools. We experienced this ourselves, unfortunately.
Stealth is great, but it’s not “zero risk”. It’s just a different type of risk.
Full-time vanlife: Standing height matters more than you think
If you plan to live in your van full-time, interior height becomes a daily quality-of-life thing. Being able to stand up:
- improves posture
- makes cooking and dressing easier
- reduces the “cramped box” feeling in bad weather
If you are able to, choose a high-roof option. The extra height is worth it.
Travelling with a partner, family or alone?
Two people changes everything. The big one: bed width and length.
After a long day (or a fun night out), the last thing you want is sleeping curled up because your bed is too short or too narrow. A slightly longer/wider van can dramatically improve sleep, which improves everything else.
A good way to choose the right van is to work backwards from how you will actually travel. A small campervan can work beautifully for two people, but it can feel very different when you add children, friends, extra luggage and more sleeping space. If you are unsure where to start, compare our guides to a campervan for 2 people and a campervan for 4 people.
Weather: Where will you actually travel?
If you travel in cold or rainy places, you’ll spend more time inside. That means you want:
- Enough space to move
- A comfortable layout
- Ventilation that prevents condensation
And if you travel in proper cold climates (like we do), remember:
- Insulate floor and ceiling more, witch reduces interior height
- So if winter travel is part of your plan, consider a van with extra headroom.
How many people must the campervan work for?

| Number of people | Usually best suited to | The most important question |
|---|---|---|
| 1 person | Small or medium van | Must it also work as an everyday vehicle? |
| 2 people | Small or medium van | Do you prioritise easy driving or standing height and indoor comfort? |
| 4 people | Medium or large van | Are there four suitable travel seats and beds without exceeding the payload? |
| 5+ people | Large van, minibus or motorhome | Can travel seats, beds, storage and payload genuinely work together? |
Campervan for 1 person
A solo traveller can often make a small van work very well. A compact bed, simple cooking equipment and well-planned storage can provide everything needed without making the vehicle difficult to drive or expensive to build.
The main question is whether the van will primarily be somewhere to sleep or a small home where you also want to work, cook and spend wet days. For longer journeys, a medium van may be worth the extra size even when you travel alone.
Campervan for 2 people
Two people have the widest choice of van sizes. A small van can work surprisingly well when the vehicle is mainly somewhere to sleep, store equipment and prepare simple meals.
A small or medium van often works well if you want easy parking, a manageable budget and a vehicle that can still be used in everyday life. It is particularly suitable when you expect to cook, sit and spend much of your time outdoors.
A large high-roof van is more useful if you want standing height, a fixed bed, a separate seating area or more comfort during longer trips.
Our detailed guide to choosing a campervan for 2 people compares van sizes, bed arrangements, headroom, storage and layouts in more detail.
Campervan for 4 people
Four people do not simply need two additional beds. You must also consider suitable travel seats, seat belts, bed lengths, personal storage and how the interior works when everyone is inside at the same time.
A medium van with a pop-top or flexible sleeping arrangement can work for two adults and two younger children on shorter holidays. For four adults, older children or longer journeys, a large high-roof van is normally more comfortable.
Before choosing the base vehicle or drawing the furniture, read our guide to a campervan for 4 people. It goes further into travel seats, beds, family layouts and payload.
Campervan for 5 people or more
For five or more travellers, the number of suitable travel seats is often the first limitation.
A large panel van may have plenty of empty cargo space, but that does not automatically make it suitable for carrying five passengers. Check the registration document, existing seats, seat-belt mountings and current local rules before designing the interior.
It is also worth comparing a DIY panel-van conversion with a minibus or ready-built motorhome. The largest panel van is not always the simplest or most economical way to transport and accommodate a larger family.
Before buying the base vehicle, read our guide to a campervan for 4 people. It explains the difference between sleeping capacity and travel seats in more detail and looks at family layouts, bed arrangements and payload.
Small, medium or large campervan?
The number of travellers gives you a starting point and he way you plan to travel usually decides the final size. The number of people gives a first direction, but your travel style often decides which size works best in practice. What do you want to get out of owning and traveling in a campervan? Is the goal to visit nice places on occasional weekends, or do you see a more permanent living solution?
A small van is easy to live with outside the holiday
The smaller class includes models like the Volkswagen Caddy, Citroën Berlingo, Renault Kangoo, and similar vehicles. This is classified as a minicamper and, for many, also functions as an everyday car with a simpler living area.
En liten van passar ofta bra om du:
- Reser ensam eller tillsammans med en person
- Främst gör helg- och sommarresor
- Vill kunna köra och parkera ungefär som med en personbil
- Accepterar ett enkelt kök och begränsad förvaring
- Inte behöver stå inne i bilen
- Vill hålla inköps- och byggkostnaden nere
Tänk ett varv till om ni vill arbeta i bilen, resa under vintern eller vistas mycket inomhus. Efter flera regniga dagar kan en liten van kännas som ett sovrum där någon glömde bygga resten av bostaden.
A medium van is often the best compromise
Medium vans include the Renault Trafic, Vauxhall Vivaro, Volkswagen Transporter, Ford Transit Custom, Mercedes Vito and Toyota Proace. They are large enough for a more complete campervan layout but usually remain easier to drive and park than a full-sized panel van.
For many first-time builders, this is where the compromises begin to feel manageable rather than constant. You can normally create a comfortable bed, compact kitchen and useful storage without turning the vehicle into something that feels oversized during the rest of the year.
Our Trafic worked particularly well because the bed and storage were the priorities. We accepted that we could not stand inside and that most cooking would happen outdoors. In return, we had a van that fitted into ordinary parking spaces and did not make every city visit feel like a driving test.
A large high-roof van gives more comfort – and more consequences
Large vans include the Fiat Ducato, Peugeot Boxer, Citroën Relay or Jumper, Renault Master, Vauxhall Movano, Mercedes Sprinter, Volkswagen Crafter and full-sized Ford Transit.
Their obvious advantage is usable interior volume. Standing height changes the way the van feels on long trips, particularly when the weather is poor. A fixed bed can remain ready while a separate table is used for eating or working, and there is more room for a proper kitchen, toilet, clothing storage and larger water or electrical systems.
That comfort is real, but so are the consequences. The vehicle costs more to buy and generally requires more material and time to convert. It may be too long or tall for some car parks, and narrow roads or busy towns require more concentration. Larger systems and more storage can also encourage you to carry equipment that you would never have considered in a smaller build.
A large van is a sensible choice when you genuinely need the interior to function as a small home. It is less convincing when most of the added space will be empty for eleven months of the year.
Before deciding, imagine both sides of ownership. Picture a cold evening when standing height and an indoor table feel invaluable. Then picture finding parking in a crowded coastal town or needing to use the van for an ordinary trip to the supermarket. The right compromise is the one you are comfortable living with on both days.
The balance changes if you want a separate seating area, an indoor toilet, a permanent work desk or several beds. A pop-top can add standing height and sleeping space, but it also adds cost and complexity. For a family, the position and approval of the travel seats may decide whether a particular medium van is suitable before the furniture has even been considered.
Requirements Checklist
We suggest writing down all your requirements for the conversion. What are your ‘must-haves’, and what can you manage without? How much space will everything take up? Having a clear picture of what you want will help you choose the right type of van for the conversion. You can use the ‘Van Conversion Map’ as a basis for your checklist.
Imagine the disappointment of buying a van only to discover that you cannot convert it! Therefore, do this first:
Contact your insurance provider:
It is helpful to refer to an already converted van of the same model to get a better understanding of the premium and what is covered in the event of an accident or break-in. Don’t hesitate to call them if you are unsure.
Check laws and regulations:
Review the laws, regulations, and requirements set for conversions in the Europe. This includes checking local guidelines like DVLA guidelines for reclassifying a vehicle as a motor caravan and ensuring compliance with gas and electrical safety standards (such as Gas Safe and BS EN standards).
What’s your budget?
Let’s not pretend: Convert a can into a fullfunctionall campervan can get expensive. So here are our recomandations to budget your conversion and estimate your campervan buildning cost.
A simple depreciation rule of thumb
A rough guideline many builders use is:
try to spend around half the van’s purchase price on the conversion.
Why? Because the more mileage you add, the more the vehicle depreciates and it’s painful to over-invest in a base van that won’t hold value.
Example, approximate:
- If you buy a van for €10,500, try to keep the conversion around €4,500–€6,500.
This isn’t a law, it’s a sanity check. Some builds justify more spend. But for many first-time builds, it prevents the classic trap: “I built something amazing and financially it made no sense.”
Estimate your build cost, the practical way
Make a list of everything you need and price it out. Then add +30% for unexpected expenses.
That becomes your conversion budget.
At the end of this series we’ll also share a complete “van conversion essentials” list to help you plan faster.
Don’t forget the non-build costs
Building is one thing, getting road-legal and running is another. Depending on your country, don’t forget:
- Road tax / environmental fees
- Insurance
- Inspection / registration checks
- Potential weight-related costs (especially near 3.5 tonnes)
These can add a surprising amount to your total.
Choosing Your Van (So the Build Is Actually Enjoyable)
Now that you’ve thought through requirements and budget, it’s time to decide what type of vehicle fits best.
My personal top pick is the Mercedes Sprinter (even though we currently have a Renault Trafic). The Sprinter is reliable, well-built and comfortable , but it often costs more upfront.
A better way to choose than “brand loyalty” is to decide based on:
- Your desired interior height
- The bed layout you want
- How much storage your life requires
- Where you’ll travel (cities vs remote, summer vs winter)
In the next parts of this series, we’ll break down van sizes and layouts in a way that’s easy to compare.
Lifestyle Fit:
Don’t Forget How You’ll Use the Van
Activities and hobbies
Think about what you want space for:
- Bikes (inside garage vs rear rack)
- Surfboards (roof storage)
- Climbing gear, hiking kit, skis
This determines storage solutions and can influence which van length/height makes sense.
Working while travelling
If you’ll work on the road, plan for:
- Internet (mobile hotspot, data plan, maybe a roof antenna later)
- A dedicated workspace (fold-out desk, swivel table, or dinette setup)
- Enough power outlets and charging options
Systems and Equipment
Power: solar and electrical system
A self-sufficient van needs a reliable power setup. If you plan to run laptops, fridge, fans, charging, and maybe an inverter:
Choosing a van with the right roof area and interior space makes this easier.
Water and waste
If you want a proper water setup:
- Fresh water tank (or jerry cans)
- Waterpump
- Filtration (optional but nice)
- Grey water plan
- Toilet option (portable or built-in)
These systems take more space than most beginners expect , especially if you want it tidy and easy to maintain.
Safety and Maintenance (The Unsexy Stuff That Saves Trips)
Safety basics
At minimum, consider:
- smoke alarm
- Carbon monoxide alarm
- Fire extinguisher
- Secure storage and additional locks
- Optional cameras/alarm for peace of mind
Maintenance and repairs
Regular maintenance keeps your van reliable and prevents expensive surprises.
Learn the basics:
- Simple troubleshooting
- Keep a small tool kit and a few spare parts so minor issues don’t end your trip.
- Tyre checks
- Oil level
Comfort and Design (Where Vanlife Becomes “Nice”)
Insulation and climate control
Good insulation isn’t just for winter, it improves comfort year-round.
Common comfort upgrades:
- Insulating floor, walls and ceiling properly
- Ventilation (roof vent / fan helps prevent condensation)
- Diesel heater if you travel in colder seasons
A van with a higher roof makes insulation less “costly” in terms of lost headroom.
Custom furniture and storage
Beds and sleeping in a campervan
The number of people travelling in the van affects the choice of base vehicle more than many beginners expect. For two people, the main questions are usually bed layout, storage and everyday comfort in a small space.
For four people, belted seats, sleeping arrangements, payload and rainy-day living become much more important. We cover those choices in more detail in our guides to a campervan for 2 people and a campervan for 4 people
To maximise space:
- Use every corner
- Build multifunctional furniture (beds with storage, fold-out tables)
- Design storage based on what you actually carry
The best builds are the ones that feel effortless to live in.
Inspiration and Resources
Follow other vanlifers
For inspiration and practical lessons, follow other builders and travellers. Many share real-world mistakes and fixes, which can save you a lot of time.
Useful tools and apps
Apps like Park4Night can help you find parking spots and campsites and reviews from other vanlifers can be surprisingly useful when you’re travelling somewhere new.
